[0046] The method provided in this embodiment can be used to Figure 1 In the first terminal 110 or the second terminal 130 in the implementation environment shown or other terminals in the implementation environment, for the convenience of description, the method will be schematically described below by taking the method applied to a computer device as an example.

[0047] Please refer to Figure 2 , which shows a flowchart of a virtual prop control method provided by an exemplary embodiment of the present application. This embodiment is described by taking the method used in a computer device as an example, and the method includes the following steps:

[0048] Step 201, in response to a view angle rotation operation, controlling a virtual object to rotate the view angle, and the virtual object holds a virtual prop.

[0049] In a possible implementation, the perspective rotation operation refers to an operation of changing the perspective of the virtual object. The perspective rotation operation may be a triggering operation of a perspective rotation control or a rotation operation of a virtual environment screen. When the computer device receives the perspective rotation operation, the virtual object is controlled to rotate the perspective. When the virtual object rotates the perspective, the virtual prop held by the virtual object moves in the direction of the perspective rotation.

[0050] Optionally, the viewing angle rotation operation may be a rotation in any direction, such as rotating the viewing angle to the left, rotating the viewing angle to the right, rotating the viewing angle upward, or rotating the viewing angle downward, etc.

[0051] Optionally, the virtual props held by the virtual object may be virtual firearms, throwing props, or melee attack props, etc.

[0052] When the virtual object does not hold a virtual prop, the object held by the virtual object may be a limb of the virtual object, such as an arm of the virtual object.

[0053] Indicatively, Figure 3 As shown, a view rotation control 301 is displayed in the virtual environment screen, and the user can change the view by triggering the view rotation control 301 .

[0054] Step 202 : during the process of the virtual object rotating its viewing angle, controlling the virtual prop to swing toward the real-time viewing angle of the virtual object, wherein there is a deviation between the real-time prop orientation of the virtual prop and the real-time viewing angle of the virtual object.

[0055] When the virtual object rotates its viewing angle, the computer device will control the virtual props to move with the viewing angle. During the movement, the virtual props will swing in the direction of the real-time viewing angle of the virtual object, thereby simulating the effect of a slight shaking during the movement of the object.

[0056] By controlling the virtual props to swing toward the real-time viewing direction of the virtual object, a deviation exists between the real-time prop direction and the real-time viewing direction, thereby achieving a hysteresis effect of the movement of the virtual props and improving the simulation authenticity.

[0057] Indicatively, Figure 3 As shown, when the virtual object rotates its viewing angle upward, at a certain moment, the real-time viewing angle direction of the virtual object is 302 , while the real-time prop direction is 303 , there is a deviation between the two, and the virtual prop swings toward the real-time viewing angle direction 302 .

[0058] Step 203, in response to the view rotation operation stopping, controlling the virtual prop to swing inertially according to the target view direction of the virtual object, the target view direction is the view direction when the virtual object stops rotating the view, and the prop orientation of the virtual prop when the inertially swinging stops is consistent with the target view direction.

[0059] Optionally, when the triggering operation of the view rotation control ends, or the rotation operation of the virtual environment screen ends, it is determined that the view rotation operation stops. When the computer device determines that the view rotation operation stops, it determines the target view direction of the virtual object.

[0060] Among them, inertial swing refers to the small shaking of the virtual props in the target viewing direction. When the viewing direction is different, the direction of inertial swing is also different. For example, when the viewing angle is rotated left and right, after the viewing angle stops rotating, the virtual props will perform inertial swing in the left and right direction; when the viewing angle is rotated up and down, after the viewing angle stops rotating, the virtual props will perform inertial swing in the up and down direction.

[0061] When the virtual prop stops its inertial swing, the prop orientation of the virtual prop will stop in the target viewing direction, that is, the prop orientation is consistent with the target viewing direction after the inertial swing stops.

[0062] Indicatively, Figure 4 As shown, when the virtual object stops rotating the viewing angle and the target viewing angle direction is 401 , the virtual prop performs an inertial swing according to the target viewing angle direction 401 , and after the inertial swing ends, the prop orientation of the virtual prop is consistent with the target viewing angle direction 401 .

[0063] To sum up, in the embodiment of the present application, in the process of controlling the rotation of the perspective of the virtual object, the virtual props held by the virtual object can be controlled to swing in the direction of the real-time perspective of the virtual object, and in the swinging process, there is a deviation between the real-time prop orientation of the virtual props and the real-time perspective direction of the virtual object, that is, the perspective of the virtual props and the virtual object do not move synchronously, thereby achieving a lag effect in the movement of the virtual props, and after the virtual object stops rotating its perspective, the virtual props are controlled to swing inertially in the direction of the target perspective, simulating the inertial motion of the object when it stops moving, thereby improving the authenticity of the virtual props following the perspective movement process during the rotation of the perspective, which helps to improve the realism of the game.

[0064] In the embodiment of the present application, a spring model is introduced, and the viewing direction of the virtual object and the prop orientation of the virtual prop are used as the two ends of the spring model, so as to achieve the hysteresis effect of the prop movement during the viewing angle rotation process and the inertial swing effect of the prop movement stopping after the viewing angle rotation stops. The following will be described with exemplary embodiments.

[0065] Please refer to Figure 5 , which shows a flow chart of a method for controlling a virtual prop provided by another exemplary embodiment of the present application. This embodiment is described by taking the method used in a computer device as an example, and the method includes the following steps:

[0066] Step 501, in response to a view angle rotation operation, controlling a virtual object to rotate the view angle, and the virtual object holds a virtual prop.

[0067] The implementation of this step can refer to the above step 201, which will not be described in detail in this embodiment.

[0068] Step 502, based on the real-time viewing angle direction and the prop orientation of the previous frame, the real-time prop orientation is determined, where the prop orientation of the previous frame is the prop orientation of the virtual prop in the previous frame image.

[0069] In a possible implementation, the virtual prop is controlled to swing by updating the swing parameters frame by frame. The real-time viewing angle direction is different from the real-time prop orientation, and the real-time prop orientation of the virtual prop in each frame is determined based on the real-time viewing angle direction of the current frame and the prop orientation of the virtual prop in the previous frame. The prop orientation of the previous frame is the prop orientation of the virtual prop in the previous frame image, and the prop orientation of the previous frame is the prop orientation of the virtual prop in the previous frame after the swing based on the swing parameters of the previous frame. That is, the prop orientation of the virtual prop is updated by iterative updating, and the swing of the virtual prop is controlled based on the prop orientation of the virtual prop.

[0070] Optionally, based on the real-time viewing angle direction and the prop orientation of the previous frame, determining the real-time prop orientation may include the following steps:

[0071] Step 502a, determining the real-time prop swing speed of the virtual prop based on the real-time viewing angle direction, the prop orientation of the previous frame, and the prop swing speed of the previous frame.

[0072] In this embodiment, a spring model is introduced, and the spring model affects the swinging process of the virtual prop, so that the real-time prop orientation of the virtual prop is different from the real-time view direction, thereby simulating the effect of the virtual prop moving lagging during the view movement process. In a possible implementation, the real-time prop orientation is determined by the spring model, and the swing parameters of the virtual prop are determined according to the real-time prop orientation. In this process, the computer device first determines the real-time prop swing speed of the virtual prop in the current frame, and then obtains the direction change amount based on the real-time prop swing speed and the frame length, and the direction change amount is the difference between the real-time prop orientation and the prop orientation of the previous frame.

[0073] Optionally, determining the real-time prop swing speed may include the following steps:

[0074] Step 1: Determine the spring model corresponding to the virtual prop, where the spring model includes the elastic coefficient and the resistance coefficient of the virtual prop during the swinging process.

[0075] Optionally, the spring model is used to simulate the force on the virtual prop during the swinging process. The spring model includes the elastic coefficient and the resistance coefficient corresponding to the virtual prop. The elastic coefficient and the resistance coefficient are used to control the swinging amplitude of the virtual prop during the swinging process.

[0076] In order to improve the simulation of different swinging conditions of different real objects during the motion process, in one possible implementation, different spring models are set for different virtual props, so that when different virtual props are held during the rotation of the virtual object, different virtual props have different swinging effects, thereby improving the simulation realism.

[0077] In the process of determining the real-time prop swing speed corresponding to the virtual prop, the computer device may determine the spring model of the virtual prop currently held by the virtual object from among the pre-stored spring models corresponding to different virtual props.

[0078] Step 2: Input the real-time viewing direction, the prop orientation in the previous frame, and the prop swing speed in the previous frame into the spring model to obtain the real-time elastic force and real-time resistance of the virtual prop.

[0079] After obtaining the spring model, the computer device can determine the real-time elastic force and real-time resistance of the virtual prop in the current frame based on the spring model.

[0080] In a possible implementation, the real-time elastic force can be determined based on the real-time viewing direction, the prop orientation of the previous frame, and the elastic coefficient. That is, the elastic force on the virtual prop is determined by multiplying the deformation amount by the elastic coefficient in the following manner:

[0081]

[0082] in, It indicates the real-time viewing direction. It means the direction of the prop in the previous frame, and Stiffness is the elastic coefficient.

[0083] The real-time viewing direction and the prop orientation of the previous frame are both two-dimensional vectors. The computer device can obtain the three-dimensional rotation amount Rotation corresponding to the real-time viewing direction and the prop orientation of the previous frame, wherein the three-dimensional rotation amount Rotation includes the pitch angle pitch, the yaw angle yaw and the roll angle roll. Schematically, as Figure 6 As shown, the pitch angle pitch is the rotation angle around the x-axis, the yaw angle yaw is the rotation angle around the y-axis, and the roll angle roll is the rotation angle around the z-axis.

[0084] However, in the actual swinging process of the virtual prop, there is only swinging in pitch and yaw, so it is only necessary to obtain the yaw component and the pitch component and represent them with a two-dimensional vector.

[0085] Among them, the real-time resistance is used to simulate the air resistance during the movement of the virtual props. Therefore, the real-time resistance can be determined by the prop swing speed and resistance coefficient of the previous frame. The method is as follows:

[0086]

[0087] in, It is the swing speed of the prop in the previous frame, and Damping is the drag coefficient.

[0088] Among them, the prop swing speed is also a two-dimensional vector with direction.

[0089] Step 3: Based on the real-time elastic force and the real-time resistance, determine the real-time swing acceleration of the virtual prop.

[0090] After obtaining the real-time elastic force and the real-time resistance, the real-time force acting on the virtual prop can be obtained based on the real-time elastic force and the real-time resistance, wherein the real-time force acting on the virtual prop is:

[0091]

[0092] After the real-time force on the virtual prop is determined, the real-time swing acceleration is determined according to the real-time force. Optionally, the mass of the virtual prop is set to 1, so the real-time swing acceleration is the real-time force.

[0093] Step 4: Determine the real-time prop swing speed based on the prop swing speed of the previous frame and the real-time swing acceleration.

[0094] After the computer device determines the real-time swing acceleration, it can use the real-time swing acceleration and frame length to determine the speed change between the prop swing speed of the previous frame and the real-time prop swing acceleration of the virtual prop in the current frame, thereby obtaining the real-time prop swing speed based on the speed change.

[0095] Optionally, the real-time prop swing speed is determined by:

[0096]

[0097] in, is the real-time prop swing speed, is the swing speed of the prop in the previous frame, DeltaTime is the frame duration, Real-time force.

[0098] In a possible implementation, the frame duration is a fixed duration, which can be determined according to the frame rate corresponding to the current picture. For example, when the frame rate is 60, the frame duration can be determined to be 1 / 60s.

[0099] In another possible implementation, the frame duration is the real-time frame duration, that is, the current frame duration, so that the real-time prop swing speed of the virtual props in the current frame is determined according to the real duration corresponding to each frame. In the process of displaying the picture, there may be a freeze in the picture. If the picture freezes, it is easy to cause the real-time frame duration of the current frame to be too long, affecting the real-time prop swing speed and the value of the real-time prop orientation of the current frame. And because the real-time prop orientation is updated frame by frame, it also affects the determination of the subsequent virtual prop orientation, thereby affecting the virtual prop swing process. Therefore, in order to reduce the impact of freezes on the swing of virtual props, in this embodiment, the minimum number of updates within one second is set, so as to determine the duration threshold according to the number. When the acquired real-time frame duration exceeds the duration threshold, the duration threshold can be determined as the frame duration.

[0100] Optionally, the minimum number of updates within one second can be determined according to the frame rate. For example, when the frame rate is 60, the minimum number of updates within one second can be set to 60, and the duration threshold is 1 / 60s. If the real-time frame duration of the current frame is greater than 1 / 60s, 1 / 60s is determined as the frame duration. If the real-time frame duration of the current frame is less than 1 / 60s, the real-time frame duration can be determined as the frame duration.

[0101] Step 502b, determining the direction change amount based on the real-time prop swing speed and frame duration.

[0102] After the computer device obtains the real-time prop swing speed, the direction change can be obtained based on the product of the real-time prop swing speed and the frame length. The direction change is the difference between the prop direction of the previous frame and the real-time prop direction.

[0103] Step 502c, based on the prop orientation and orientation change amount of the previous frame, determine the real-time prop orientation.

[0104] After the direction change is determined, the real-time prop direction can be obtained based on the direction change and the prop direction of the previous frame. The calculation method is as follows:

[0105]

[0106] in, This is the real-time prop orientation. is the prop orientation of the previous frame, is the direction change.

[0107] Step 503: Determine the swing parameter of the virtual prop based on the real-time direction deviation between the real-time prop orientation and the real-time viewing angle direction.

[0108] The swing parameter is used to indicate the amplitude of the swing of the virtual prop. The computer device finally controls the virtual prop to swing in the direction of the real-time viewing angle based on the swing parameter.

[0109] In a possible implementation, the computer device determines the swing parameter by a real-time direction deviation between the real-time prop orientation and the real-time viewing angle direction. The real-time direction deviation may be:

[0110]

[0111] in, That means real-time direction deviation. is the real-time viewing direction, The real-time prop orientation.

[0112] Indicatively, Figure 7 As shown, for and That is, the real-time view direction and the real-time direction deviation are used to control the virtual props to swing to the real-time prop direction.

[0113] The real-time direction deviation is the deviation between the real-time viewing direction and the real-time prop orientation. If the swing of the virtual prop is directly controlled based on the real-time direction deviation, the virtual prop may be offset too much, resulting in poor simulation effect. Therefore, the swing parameter can be determined according to the real-time direction deviation, and the swing of the virtual prop can be controlled based on the swing parameter. This method may include the following steps:

[0114] Step 503a: determining a candidate direction deviation based on the real-time direction deviation and the deviation threshold, where the deviation threshold is the maximum deviation value between the viewing direction of the virtual object and the prop orientation of the virtual prop.

[0115] Therefore, in this embodiment, a deviation threshold is set to control the swing amplitude of the virtual props to avoid excessive swing. The deviation threshold is the maximum deviation value between the viewing angle direction of the virtual object and the prop orientation of the virtual props, to avoid excessive deviation between the real-time prop orientation of the virtual props and the real-time viewing angle direction.

[0116] In a possible implementation, one of the real-time direction deviation and the deviation threshold is selected as the candidate direction deviation.

[0117] Optionally, when the real-time direction deviation is less than the deviation threshold, the real-time direction deviation is determined as a candidate direction deviation.

[0118] Optionally, when the real-time direction deviation is greater than the deviation threshold, the deviation threshold is determined as the candidate direction deviation.

[0119] After the deviation threshold is determined as the candidate direction deviation, the real-time prop orientation needs to be updated based on the candidate direction deviation. The updated real-time prop orientation is:

[0120]

[0121] in, This is the updated real-time prop orientation. is the candidate direction deviation.

[0122] Step 503b, interpolating the candidate direction deviations to obtain the target direction deviation.

[0123] In this embodiment, the swing parameters are updated frame by frame to control the swing of the virtual props frame by frame. Therefore, if the swing parameters between two frames differ too much, the swing amplitude of the virtual props will be relatively abrupt. Therefore, in order to make the swing process of the virtual props smooth, in this embodiment, after obtaining the candidate direction deviation, the candidate direction deviation is also interpolated to obtain the target direction deviation. The interpolation process may include the following process.

[0124] Step 1: Get the target direction deviation of the previous frame and the interpolation speed corresponding to the virtual props.

[0125] In order to avoid a large difference in the swing parameters between two frames, in a possible implementation, an interpolation process is performed in the interval between the target direction deviation of the previous frame and the candidate direction deviation determined in the current frame.

[0126] Optionally, interpolation is performed through interpolation speed and frame duration. The interpolation speed is used to control the size of the interpolation. When the interpolation speed is larger, the difference between the target direction deviation determined by the current frame and the target direction deviation of the previous frame is larger. Correspondingly, the difference between the swing parameters of the current frame and the swing parameters of the previous frame is larger, so that the swing amplitude of the virtual prop jumps larger, that is, the swing effect is more shaky.

[0127] Step 2: Based on the interpolation speed, the target direction deviation of the previous frame and the candidate direction deviation are interpolated to obtain the target direction deviation.

[0128] In a possible implementation, the interpolation processing is performed according to the interpolation speed as follows:

[0129]

[0130] in, Indicates the target direction deviation, Indicates the target direction deviation of the previous frame, It represents the candidate direction deviation, and speed represents the interpolation speed.

[0131] Step 503c, adjusting the target direction deviation based on the swing coefficient to obtain the swing parameter of the virtual prop, and the swing coefficient is used to control the overall prop swing amplitude of the virtual prop.

[0132] In this embodiment, the overall swing amplitude of the virtual prop is controlled by setting the swing coefficient. Different virtual props may correspond to different swing coefficients. Optionally, the swing coefficient is positively correlated with the overall swing amplitude.

[0133] After determining the target direction deviation of the virtual prop, the computer device further adjusts the target direction deviation through the swing coefficient, thereby obtaining the swing parameter of the virtual prop.

[0134] Optionally, the swing parameter can be: Among them, alpha is the swing coefficient.

[0135] Step 504: Based on the swing parameter, the virtual prop is controlled to swing toward the real-time viewing angle.

[0136] In a possible implementation, based on the swing parameter, the virtual prop is controlled to swing in the direction of the real-time viewing angle in the current frame, and in the process of determining the swing parameter in the next frame, the swing parameter of the next frame is determined based on the prop direction after the swing of the virtual prop in the current frame and the real-time viewing angle direction of the next frame. That is, the virtual prop is controlled to swing in the direction of the real-time viewing angle by updating the swing parameter in each frame.

[0137] The process of determining the current frame swing parameter is schematically described below.

[0138] When the elastic coefficient Stiffness of the virtual prop is 200 and the resistance coefficient Damping is 10, if the current viewing direction is {Pitch=21.7033615,Yaw=197.361603,Roll=0.00000000}, determine the real-time viewing direction of the current frame is (197.36, 21.70), and accordingly, the prop orientation of the previous frame is obtained When the prop swing speed in the previous frame is (-168.05, 16.34) and (1.56, 76.38), the process of determining the real-time prop orientation in the current frame is as follows:

[0139] Substituting the above values ​​into the following formula, we can obtain the real-time force of the virtual prop as (1066.4, 308.2).

[0140]

[0141] It should be noted that in the process of calculating the difference between the real-time viewing direction and the prop direction of the previous frame, the shortest distance needs to be calculated. That is, when the difference between 197.36 and -168.05 is 365.41, the shortest distance needs to be determined. The shortest distance is the difference between 365.41 and modulo 360, which is 5.41.

[0142] After the real-time force is obtained, the real-time prop swing speed can be obtained based on the frame length 1 / 60s and the prop swing speed of the previous frame (1.56, 76.38). That is, by substituting it into the following formula, the real-time prop swing speed can be obtained as (19.33, 81.52).

[0143]

[0144] After that, the real-time prop swing speed and the prop swing direction of the previous frame can be used to obtain the real-time prop direction, which can be substituted into the following formula to obtain the real-time prop direction is (-167.73, 17.70).

[0145]

[0146] The real-time direction deviation is obtained by using the real-time prop orientation and the real-time viewing direction, which can be substituted into the following formula to obtain the real-time direction deviation as (5.09, 4.00).

[0147]

[0148] The deviation threshold corresponding to the virtual prop is 5, so the candidate direction deviation is determined to be (5.00, 4.00).

[0149] After obtaining the candidate direction deviation, the real-time prop orientation needs to be updated based on the candidate direction deviation. The updated real-time prop orientation is (-167.64, 17.70).

[0150] The target direction deviation of the virtual prop in the previous frame is (0.046, 1.34), which needs to be interpolated. The interpolation speed is 4. After interpolation, the target direction deviation is (0.376, 1.52).

[0151] Among them, the swing coefficient is 0.2. The swing coefficient is adjusted for the target direction deviation, and the swing parameter is (0.0752, 0.304). Converting it to a three-dimensional rotation value gives:

[0152] RotOffset={Pitch=0.304, Yaw=0.0752, Roll=0}

[0153] Step 505: in response to the view angle rotation operation stopping, obtain the real-time prop swing speed.

[0154] After the view rotation operation stops, the computer device controls the virtual prop to swing inertially according to the target view direction. In this process, the virtual prop is controlled to swing inertially based on the way of updating the swing parameters frame by frame.

[0155] The method of updating the swing parameters frame by frame may refer to the method of determining the swing parameters of the virtual props based on the real-time direction deviation between the real-time prop orientation and the real-time viewing angle in the above step.

[0156] After the view rotation operation stops, the real-time view direction will no longer change, that is, it stops at the target view direction, so that the swing parameter of the virtual prop is determined based on the direction deviation between the target view direction and the real-time prop orientation. After the view rotation operation stops, the real-time prop orientation of the virtual prop is determined in the same manner as in step 502, and will not be described in detail in this embodiment.

[0157] After the view rotation operation stops, in the process of updating the swing parameters frame by frame, the real-time prop swing speed is obtained based on the prop swing speed of the previous frame and the real-time force acting on the virtual prop.

[0158] Step 506: When the real-time prop swing speed is greater than the speed threshold, the virtual prop is controlled to swing inertially in the target viewing direction of the virtual object.

[0159] When the real-time prop swing speed of the virtual prop is less than a certain value, the virtual prop will continue to be in a slight shaking state. In order to avoid the virtual prop from continuing to swing slightly, a speed threshold is set in this embodiment. When the acquired real-time prop swing speed is greater than the speed threshold, the real-time prop orientation can continue to be determined according to the real-time prop swing speed, and the real-time direction deviation between the target viewing angle direction and the real-time prop orientation can be used to determine the swing parameters of the virtual prop, thereby controlling the virtual prop to swing inertially based on the swing parameters.

[0160] Step 507: When the real-time prop swing speed is less than the speed threshold, the virtual prop is controlled to stop inertial swing.

[0161] When the real-time prop swing speed is less than the speed threshold, it indicates that the virtual prop is shaking at a very small amplitude. At this time, the virtual prop can be controlled to stop the inertial swing, thereby optimizing the inertial swing process of the virtual prop and saving a certain performance overhead.

[0162] In this embodiment, a spring model is introduced to determine the real-time prop orientation of the virtual prop according to the force applied to the virtual prop, thereby determining the swing parameter frame by frame based on the deviation between the real-time prop orientation and the target viewing angle direction, and controlling the virtual prop to swing frame by frame, thereby achieving the hysteresis effect of the virtual prop movement during the viewing angle rotation process and the inertial swing effect of the virtual prop movement stopping after the viewing angle rotation stops. On the one hand, the swing effect of objects in the real world can be simulated to improve the authenticity of the game simulation; on the other hand, in the process of controlling the swing of the virtual prop, the computer calculates the swing parameter frame by frame, thereby controlling the virtual prop to swing based on the swing parameter, without the need to design a specific swing animation, which can save animation resources and memory usage during program operation.

[0163] In this embodiment, when the virtual prop is controlled to swing, the swing is performed with the virtual axis corresponding to the virtual prop as the center, and the axis positions of the virtual axes corresponding to different virtual props are different.

[0164] Optionally, when the virtual object rotates its viewing angle, the virtual prop is controlled to swing toward the real-time viewing angle with the virtual axis as the center.

[0165] Optionally, in response to the view rotation operation stopping, the virtual prop is controlled to swing inertially in the target view direction with the virtual axis as the center.

[0166] That is, after obtaining the swing parameters, the virtual prop is controlled to swing around the virtual axis based on the real-time viewing direction. Figure 8 As shown, based on the virtual axis 801 of the virtual prop, the virtual prop is swung to a position 802 .

[0167] When controlling the swing of a virtual prop, the skeleton animation corresponding to the virtual prop can be controlled to rotate around the virtual axis.

[0168] In a possible implementation, when the axis position of the virtual axis of the virtual prop is different, different swing effects are achieved.

[0169] When the first distance is smaller than the second distance, the swing amplitude of the head position of the virtual prop is smaller than the swing amplitude of the tail position of the virtual prop. The first distance is the distance between the head position of the virtual prop and the axis position, and the second distance is the distance between the tail position of the virtual prop and the axis position.

[0170] When the first distance is greater than the second distance, the swing amplitude of the head position of the virtual prop is greater than the swing amplitude of the tail position of the virtual prop.

[0171] Indicatively, when the virtual prop is a virtual firearm, when the virtual axis position is close to the virtual firearm head position, when swinging based on the virtual axis, the swing amplitude of the virtual firearm head is smaller than the swing amplitude of the virtual firearm tail. When the virtual axis position is close to the virtual firearm tail position, when swinging based on the virtual axis, the swing amplitude of the virtual firearm head is larger than the swing amplitude of the virtual firearm tail.

[0172] When setting the axis position of the virtual axis corresponding to different virtual props, it can be determined according to the swing requirements. If the swing amplitude of the head position of the virtual prop is required to be larger, the axis position of the virtual axis can be set near the tail position of the virtual prop; if the swing amplitude of the tail position of the virtual prop is required to be larger, the axis position of the virtual axis can be set near the head position of the virtual prop.

[0173] In addition to the axis position of the virtual axis, different virtual props correspond to different elastic coefficients, resistance coefficients, deviation thresholds, interpolation speeds, and swing coefficients, so that different virtual props have different swing effects and improve the simulation realism.

[0174] In a possible implementation, different parameters corresponding to the virtual props may be determined according to the swing effect requirements of the virtual props.

[0175] When the virtual object rotates its viewing angle, the swing of the virtual prop is controlled to simulate the swing of the real moving object. When the prop type corresponding to the virtual prop is a heavy prop, the swing amplitude of the virtual prop needs to be controlled within a smaller range. In this case, this can be achieved by changing the elastic coefficient and the resistance coefficient. The elastic coefficient is positively correlated with the swing amplitude. Therefore, when the swing amplitude of the virtual prop needs to be controlled to be smaller, a smaller elastic coefficient can be set, and the resistance coefficient needs to be adjusted accordingly during the adjustment of the elastic coefficient.

[0176] To further control the swing amplitude, the deviation threshold and the swing coefficient can be changed. The deviation threshold limits the orientation deviation of the virtual prop, and the swing coefficient adjusts the overall swing amplitude of the prop. The stability of the virtual prop can also be adjusted by adjusting the interpolation speed of the virtual prop. When the weight of the virtual prop is large, the swing amplitude of the virtual prop needs to be controlled to be smaller and the stability is higher. Therefore, a smaller deviation threshold, swing coefficient and interpolation speed can be set.

[0177] In the process of setting the axis position of the virtual axis of different virtual props, it can be determined according to the prop length and swing requirement of the virtual prop.

[0178] Indicatively, when the virtual item is a medium-sized virtual item, the parameters corresponding to the heavy-duty virtual item are shown in Table 1:

[0179] Table 1

[0180] Elastic coefficient 200 Drag coefficient 10 Deviation threshold 5 Swing coefficient 0.2 Interpolation speed 4 Virtual axis position X: 50.0; Y: 0.0; Z: 0.0

[0181] When the virtual props are micro virtual props, the corresponding parameters are shown in Table 2:

[0182] Table 2

[0183] Elastic coefficient 420 Drag coefficient 15 Deviation threshold 20 Swing coefficient 0.4 Interpolation speed 6 Virtual axis position X: 10.0; Y: 0.0; Z: 0.0

[0184] Among them, the weight of the medium-sized virtual prop is greater than that of the micro-sized virtual prop, and the swing amplitude of the medium-sized virtual prop needs to be smaller than that of the micro-sized virtual prop. The medium-sized virtual prop is more stable during movement than the micro-sized virtual prop. Therefore, the elasticity coefficient of the medium-sized virtual prop is smaller than that of the micro-sized virtual prop. The elasticity coefficient of the medium-sized virtual prop is 200, and the elasticity coefficient of the micro-sized virtual prop is 420. When the elasticity coefficient is large, the resistance coefficient also needs to be increased to avoid the virtual gun swinging for too long. Therefore, the resistance coefficient of the micro-sized virtual prop is 15, which is greater than the resistance coefficient of the medium-sized virtual prop of 10. And accordingly, the deviation threshold, swing coefficient and interpolation speed of the medium-sized virtual prop are all smaller than the deviation threshold, swing coefficient and interpolation speed of the micro-sized virtual prop.

[0185] In a possible implementation, when the swing amplitude of the virtual prop head position is set to be smaller than the swing amplitude of the virtual prop tail position, the virtual axis position can be close to the virtual prop head position. For example, when the virtual prop is a virtual firearm, the virtual axis position can be close to the gun head position. Combining the examples in Table 1 and Table 2, the prop length of a medium-sized virtual prop is 65cm, the origin is the virtual prop tail position, and the x-axis is the prop orientation. The virtual axis position can be set to be 15cm away from the virtual prop head position, that is, X is 50.

[0186] When the virtual prop is a heavy virtual prop, since the weight of the heavy virtual prop is greater than that of the medium virtual prop, the swing amplitude needs to be controlled to be smaller. Therefore, the parameters corresponding to the heavy virtual prop can be shown in Table 3:

[0187] Table 3

[0188] Elastic coefficient 300 Drag coefficient 20 Deviation threshold 3 Swing coefficient 0.2 Interpolation speed 4 Virtual axis position X: 60.0; Y: 0.0; Z: 0.0

[0189] When the virtual prop is a light virtual prop, its weight is less than that of an assault rifle and greater than that of a micro virtual prop. Its corresponding parameters are shown in Table 4:

[0190] Table 4

[0191] Elastic coefficient 280 Drag coefficient 12 Deviation threshold 5 Swing coefficient 0.2 Interpolation speed 6 Virtual axis position X: 60.0; Y: 0.0; Z: 0.0

[0192] In another possible implementation, when the virtual object does not hold a virtual prop, that is, has no hands, during the corresponding rotation of the virtual object, the hand position of the virtual object also swings in the direction of the real-time viewing angle, and after the viewing angle rotation operation stops, the hand position of the virtual object swings inertially in the direction of the target viewing angle. Schematically, the parameters corresponding to the hand position of the virtual object can be shown in Table 5:

[0193] Table 5

[0194] Elastic coefficient 200 Drag coefficient 10 Deviation threshold 20 Swing coefficient 0.2 Interpolation speed 6 Virtual axis position X: 0.0; Y: 0.0; Z: 0.0

[0195] After controlling the virtual object to rotate the viewing angle, the computer device first determines whether the current swing function is turned on. Only when the swing function is turned on can the virtual prop be controlled to swing. The following will be described with exemplary embodiments.

[0196] Please refer to Fig. 9 , which shows a flow chart of a method for controlling a virtual prop provided by another exemplary embodiment of the present application. This embodiment is described by taking the method used in a computer device as an example, and the method includes the following steps:

[0197] Step 901, in response to a view angle rotation operation, controlling a virtual object to rotate the view angle, and the virtual object holds a virtual prop.

[0198] The implementation of this step can refer to the above step 201, which will not be described in detail in this embodiment.

[0199] Step 902: When the virtual object is rotating its viewing angle and the swing function is turned on, the virtual prop is controlled to swing in the direction of the real-time viewing angle of the virtual object.

[0200] In a possible implementation, the computer device may determine whether the swing function is turned on according to the prop states of different virtual props.

[0201] When the virtual props are in use, the stability requirement of the virtual props is high. For example, when the virtual object is rotating the view angle, the virtual props are used to attack. At this time, the stability requirement of the virtual props is high. If the virtual props swing, it will affect the use of the virtual props. Therefore, when the virtual props are not in use, it is determined that the swing function is turned on. When the virtual props are in use, it is determined that the swing function is turned off.

[0202] In another possible implementation, whether the swing function is turned on can be determined based on the quality of the virtual environment picture. Since the user may use a low-quality mode to display the virtual environment picture, or the current computer device can only support a low-quality model. Under the low-quality model, the picture quality requirement is low, and there is no need to display the swing of the virtual props during the rotation of the view and the inertial swing process after the rotation of the view stops, thereby avoiding screen freezes. Therefore, when the virtual environment picture is of low quality, it is determined that the swing function is turned off, and when the virtual environment picture quality is of high quality, it is determined that the swing function is turned on.

[0203] Alternatively, in another possible implementation, a swing function on or off control may be provided, for example, in a screen setting interface or a virtual environment screen. When the computer device receives a user's on operation for the swing function control, it determines that the swing function is on, and when the computer device receives a user's off operation for the swing function control, it determines that the swing function is off.

[0204] During the process of the virtual object rotating the viewing angle, if the swing function is confirmed to be turned on, the required props can be controlled to swing in the direction of the real-time viewing angle of the virtual object.

[0205] Step 903: in response to the view rotation operation stopping, the virtual prop is controlled to swing inertially in the target view direction of the virtual object.

[0206] When the view rotation operation stops, the virtual prop is controlled to swing inertially in the target view direction of the virtual object.

[0207] Step 904, when the virtual object rotates its viewing angle and the swing function is not enabled, the virtual prop is controlled to rotate synchronously with the viewing angle of the virtual object, wherein during the synchronous rotation, the direction of the real-time prop is the same as the direction of the real-time viewing angle.

[0208] During the process of the virtual object rotating its viewing angle, if the swing function is not turned on, the virtual props are controlled to rotate synchronously with the viewing angle of the virtual object. During this process, the virtual props do not swing in the direction of the real-time viewing angle, and the real-time prop direction of the virtual props remains the same as the real-time viewing angle direction of the virtual object.

[0209] And if the swing function is not turned on, the virtual props will not have an inertial swing process after the view stops rotating.

[0210] In this embodiment, when the virtual props are in use, the swing function of the virtual props is turned off, thereby helping to improve the stability of the use of the virtual props. And when the current image quality is low, the swing function of the virtual props is turned off to avoid image freezes.

[0211] In a possible implementation, the control process of the virtual props can be as follows: Fig.10 As shown:

[0212] Step 1001, in response to a view angle rotation operation, controlling the virtual object to rotate the view angle.

[0213] Step 1002, determine whether the swing function is turned on, if so, execute step 1003, if not, execute step 1014.

[0214] Step 1003: determine the real-time force acting on the virtual prop based on the real-time viewing angle direction and the prop orientation of the previous frame.

[0215] Step 1004, determining the real-time prop swing speed based on the real-time force and the prop speed of the previous frame.

[0216] Step 1005 , determining whether the real-time prop swing speed is greater than a speed threshold, if so, executing step 1006 , if not, executing step 1012 .

[0217] Step 1006, determining the real-time prop orientation based on the real-time prop swing speed and the prop orientation of the previous frame.

[0218] Step 1007, determining the real-time direction deviation between the real-time prop direction and the real-time viewing direction.

[0219] Step 1008 : determining a candidate direction deviation based on the real-time direction deviation and the deviation threshold.

[0220] Step 1009: Update the real-time prop orientation based on the candidate orientation deviation.

[0221] Step 1010, interpolating the candidate direction deviations to obtain the target direction deviation.

[0222] Step 1011, adjusting the target direction deviation by the swing coefficient to obtain the swing parameter.

[0223] Step 1012: Based on the swing parameter, control the virtual prop to swing around the virtual axis.

[0224] Step 1013, controlling the virtual prop to stop swinging.

[0225] Step 1014, controlling the virtual props to rotate synchronously with the virtual object perspective.
