[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0022] Figure 1 is a flow chart of a virtual object control method provided by an embodiment of the present invention. Figure 1 The embodiment of the present invention provides a virtual object control method, wherein the virtual object includes a plurality of interconnected virtual entities, and the method may specifically include the following steps: Step 101: In response to a deflection operation on a virtual object, determine a first vector from a target point to a deflection point indicated by the deflection operation.
[0023] It should be noted that the execution subject of the virtual object control method provided in the embodiment of the present invention may be a game engine, an electronic device running a game engine, a component in an electronic device, an integrated circuit or a chip. The electronic device may be a mobile electronic device or a non-mobile electronic device. For example, the mobile electronic device may be a mobile phone, a tablet computer, a laptop computer, a PDA, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc., and the non-mobile electronic device may be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc., which is not specifically limited in the embodiment of the present invention. The following embodiment of the present invention is described with the game engine as the execution subject.
[0024] The embodiment of the present invention can be applied to the generation of three-dimensional animation. When an associated event is triggered, the actions involved in the virtual object control method provided by the embodiment of the present invention can be executed in each animation frame. By controlling and modifying the posture of the virtual object, the corresponding animation effect can be rendered on the display.
[0025] The embodiments of the present invention can be applied to various game scenarios. For example, in a game attack scenario, the virtual object control method provided by the embodiments of the present invention can be used to control the combat posture of the virtual object during the game, so as to render and generate animation effects in the combat state on the display, such as combat animations that require sideways movement, such as crossing cover design, avoiding counterattacks, etc.
[0026] A virtual object may include multiple interconnected virtual entities. These entities are the basic framework for controlling the actions of the virtual object. Through the transformations of these entities such as rotation and translation, the actions and postures of the virtual object can be controlled, so that the virtual object can perform various actions such as walking, running, jumping, fighting, etc.
[0027] The virtual object may be a skeleton module in a game character model, and the virtual entity may be a specific skeleton or a weapon held by the game character.
[0028] The aiming point can be the point used for attacking. When designing an animation, you can specify an aiming point, such as the firing port of a weapon, the face of a fist, etc.
[0029] The deflection point of the deflection operation indication may refer to the indicated position input by the player in the virtual space during the game to control the virtual object to make a deflection action. For example, the player can control the virtual object to move to the left by pressing the q button, and control the virtual object to move to the right by pressing the e button. The position of the deflection point may change with the duration of pressing the button.
[0030] When designing animations, game designers can set the way players input deflection points, such as inputting through the qe button, and the numerical range of the deflection points. During the game, the player can input a specific numerical value within the numerical range of the deflection point, thereby indicating the deflection of the virtual object in the virtual space; the duration of the player pressing the qe button can also be converted into a specific numerical value within the numerical range of the deflection point, thereby indicating the deflection of the virtual object.
[0031] Specifically, during the game, if a player's deflection operation on a virtual object is detected, the deflection operation can be responded to, the coordinates of the deflection point indicated by the deflection operation and the coordinates of the aiming point can be obtained, and the first vector from the aiming point to the deflection point can be determined based on the coordinates of the deflection point and the coordinates of the aiming point.
[0032] Step 102, performing Schmidt orthogonalization on the forward vector of the target entity where the aiming point is located and the first vector to obtain a deflection vector.
[0033] The entity where the aiming point is located is the target entity. The target entity can be a virtual entity in the virtual object (such as the fist of the game character) or a virtual entity outside the virtual object (such as the handheld weapon of the game character), which can be specifically defined by the game designer during editing. For example, when designing an animation, if the designed aiming point is the weapon launch port, the target entity where the aiming point is located can be the handheld weapon of the game character; if the designed aiming point is the fist surface, the target entity where the aiming point is located can be the fist of the game character.
[0034] Any virtual entity can have a predefined orientation, and a vector consistent with the orientation can be the forward vector of the entity. Any entity can have a predefined origin, which can be located at the center of the entity or a fixed point of the entity, and the origin can be used to define the position, rotation and scale of the virtual entity.
[0035] During the game, the position of the deflection point may be in front of or behind the aiming point. The embodiment of the present invention obtains the deflection vector by Schmidt orthogonalizing the forward vector of the target entity where the aiming point is located and the first vector from the aiming point to the deflection point, so that no matter whether the player inputs an orthogonal deflection point, it can remain orthogonal to the forward vector of the aiming point, that is, the deflection vector can always be orthogonal to the direction of the target entity where the aiming point is located, so that the calculated entity chain controls the posture of the virtual object to bend toward the deflection point while keeping the forward vector of the aiming point unchanged.
[0036] Step 103: Based on the deflection vector, control the posture of the virtual object to bend toward the deflection point.
[0037] In the embodiment of the present invention, the relevant virtual entity in the virtual object may be deflected toward the deflection point based on the deflection vector, thereby controlling the posture of the virtual object to bend toward the deflection point.
[0038] The embodiment of the present invention determines a first vector from an aiming point to a deflection point indicated by a deflection operation in response to a deflection operation on a virtual object; performs Schmidt orthogonalization on a forward vector and the first vector of a target entity where the aiming point is located to obtain a deflection vector; based on the deflection vector, controls the posture of the virtual object to bend toward the deflection point, thereby automatically modifying the posture of the virtual object on the basis of a basic combat animation frame, and rendering a corresponding combat animation frame, without having to design an animation clip for each action of the virtual object, thereby saving development resources and improving the authenticity of the game effect.
[0039] Based on any of the above embodiments, performing Schmidt orthogonalization on the forward vector of the target entity where the aiming point is located and the first vector to obtain the deflection vector may specifically include: Step S11, taking the forward vector of the target entity where the aiming point is located as a reference vector, calculating the projection vector of the first vector on the reference vector; Step S12, subtracting the first vector from the projection vector to obtain a deflection vector orthogonal to the forward vector of the target entity where the aiming point is located.
[0040] Specifically, the forward vector A of the target entity where the aiming point is located can be defined as the reference vector u1. The projection vector of the first vector B from the aiming point to the deflection point on the reference vector u1 can be calculated:
[0041] The first vector can be subtracted from the projection vector to remove the projection of the first vector on the reference vector, and a deflection vector orthogonal to the forward vector of the target entity where the aiming point is located can be obtained:
[0042] The embodiment of the present invention uses the forward vector of the target entity where the aiming point is located as the reference vector, calculates the projection vector of the first vector from the aiming point to the deviation point on the reference vector, and removes the projection of the first vector on the reference vector, so as to obtain a deviation vector that is orthogonal to the forward vector of the target entity where the aiming point is located, so that no matter whether the player input is an orthogonal deviation point, it can remain orthogonal to the forward vector of the aiming point, that is, the deviation vector can always be orthogonal to the orientation of the target entity where the aiming point is located, so that the calculated entity chain controls the posture of the virtual object to bend toward the deviation point while keeping the forward vector based on the aiming point unchanged.
[0043] Based on any of the above embodiments, controlling the posture of the virtual object to bend toward the deflection point based on the deflection vector may specifically include: Step S21, determining a second vector from a first entity to a last entity in a target entity chain in the virtual object, and determining a first vector angle based on the deflection vector and the second vector; Step S22: interpolating the entities in the target entity chain toward the deflection vector based on the first vector angle, so as to control the posture of the virtual object to bend toward the deflection point.
[0044] An entity chain may refer to a group of virtual entities connected in sequence. Any two adjacent entities on the entity chain have an active angle in one or more directions.
[0045] The target entity chain in the virtual object can refer to the bone chain specified by the game animation designer, for example, it can be the bone chain between the waist bone and the head bone. Each bone in the bone chain can have a predefined orientation, which can be regarded as the forward vector of this bone, such as the facial orientation of the head bone and the orientation of the sternum. These parameters can be preset by the game animation designer.
[0046] The first entity in the target entity chain may refer to a waist bone, and the last entity in the target entity chain may refer to a head bone. The waist bone and the head bone may be connected in sequence by multiple bones.
[0047] Specifically, the second vector from the first entity to the last entity in the target entity chain in the virtual object can be determined, and a vector angle can be determined based on the deviation vector and the second vector. Based on the first vector angle, linear interpolation of the deviation vector is performed on the entities in the target entity chain, so that the target entity chain in the virtual object bends toward the deviation point, thereby controlling the posture of the virtual object to bend toward the deviation point.
[0048] It should be noted that, when designing game animations, for game attack scenes, the position of the first entity (i.e., the waist bone) usually remains unchanged. In the embodiment of the present invention, when controlling the posture of the virtual object to bend toward the deflection point, the first entity in the target entity chain may not bend toward the deflection point.
[0049] It should be noted that, when designing game animation, the embodiment of the present invention specifies the target entity chain as the bone chain from the waist bone to the head bone, so that the attack action can be achieved by changing the upper body posture of the virtual object in game attack scenarios such as shooting scenes and fighting scenes.
[0050] In an embodiment of the present invention, when designing an animation, the designer only needs to pay attention to the input of the deflection point. Then, during the game, the target entity chain in the virtual object can be controlled to deflect toward the deflection point according to the deflection point input by the player, so that the posture of the virtual object bends toward the deflection point, thereby displaying the animation effect of the virtual object turning sideways on the display through rendering.
[0051] Based on any of the above embodiments, interpolating the entities in the target entity chain toward the bias vector based on the first vector angle may specifically include: Step S221, for each entity in the target entity chain, determining the magnitude of the deviation of each entity toward the deviation vector according to the limit value of the angle of each entity relative to the first vector; Step S222: interpolating the deviation vector of each entity based on the magnitude of the deviation of each entity toward the deviation vector.
[0052] The limit value may range from 0 to 1, the limit value corresponding to the first entity on the target entity chain may be 0, the limit value corresponding to the last entity on the target entity chain may be 1, and the limit values corresponding to the entities on the target entity chain may increase in sequence according to the order in which the entities are connected.
[0053] Specifically, when designing a game animation, the first distance from an entity in the target entity chain to the first entity and the second distance from the first entity to the last entity can be obtained, the ratio of the first distance to the second distance can be calculated, and the ratio can be set as the limit value corresponding to the entity; during the game, the deflection amplitude (i.e., arc length) of the entity can be calculated based on the limit value corresponding to the entity and the angle between the first vector, so that the entity deviates to one side of the deflection point according to the deflection amplitude.
[0054] Interpolation may include linear interpolation and spherical interpolation. In an embodiment of the present invention, when entities on the target entity chain are deflected according to the deflection amplitude, linear interpolation of the deflection vector may be performed on the entities on the target entity chain. Compared with spherical interpolation, this can reduce performance consumption and provide a smooth transition, which is conducive to further improving the naturalness and authenticity of the game effect.
[0055] Based on any of the above embodiments, before responding to a deflection operation on a virtual object and determining a first vector from a target point to a deflection point indicated by the deflection operation, the method further includes: Step S31, in response to the aiming operation for the attack point, determining a third vector from the last entity in the target entity chain in the virtual object to the attack point, and a forward vector of the first entity in the target entity chain; Step S32, determining the second vector angle based on the third vector and the forward vector of the first entity; Step S33: interpolating the entities in the target entity chain toward the third vector based on the second vector angle, so as to control the last entity in the target entity chain to face the attack point.
[0056] The attack point may refer to a target point indicated by a player during a game, such as a target selected by a player during a game, or an attack position point indicated by an operation indicator.
[0057] During the game, if the player's aiming operation at the attack point is detected, the aiming operation can be responded to, the coordinates of the origin of the last entity in the target entity chain and the coordinates of the attack point can be obtained, and the third vector from the origin of the last entity to the attack point can be determined based on the coordinates of the origin of the last entity and the coordinates of the attack point.
[0058] The first entity in the target entity chain may have a predefined orientation, and the vector consistent with the predefined orientation may be the forward vector of the first entity. A vector angle may be determined based on the third vector and the forward vector of the first entity, and then based on the second vector angle, the entities in the target entity chain are linearly interpolated toward the third vector, so that the orientation of the entities on the target entity chain in the virtual object is consistent with the orientation of the third vector, thereby controlling the head bone of the virtual object to be oriented toward the attack point (and the posture of the virtual object is also oriented toward the attack point).
[0059] It should be noted that for game attack scenarios, before the orientation of the virtual object changes, the forward vectors of the first entity and the last entity in the target entity chain can be consistent; in the process of controlling the last entity in the target entity chain toward the attack point, the forward vector of the last entity can change, while the forward vector of the first entity (i.e., the waist bone) usually remains unchanged. The forward vector of the first entity can be used to determine the angle of the second vector to avoid deviation in the orientation of the virtual object.
[0060] In an embodiment of the present invention, when designing an animation, the designer only needs to set the head bone of the virtual object (i.e., the game character) as the last entity in the entity chain. Then, during the running of the game, by controlling the last entity in the target entity chain to face the attack point, the face of the character model is automatically directed toward the target object. There is no need to design an animation clip for each action of the virtual object, thereby increasing the realism of the game.
[0061] Based on any of the above embodiments, the method may further include: interpolating the target entity where the aiming point is located toward the third vector to control the target entity where the aiming point is located toward the attack point.
[0062] After interpolating the entities in the target entity chain toward the third vector to control the last entity in the target entity chain to be oriented toward the attack point, the target entity where the aiming point is located can be interpolated according to the third vector so that the orientation of the target entity is consistent with the orientation of the last entity in the target entity chain, that is, consistent with the orientation of the third vector, thereby controlling the target entity where the aiming point is located to be oriented toward the attack point.
[0063] In an embodiment of the present invention, when designing an animation, the designer only needs to set the aiming point. Then, during the running of the game, the target entity where the aiming point is located can be controlled to automatically move toward the attack point indicated by the player, and the corresponding picture can be displayed by rendering. There is no need to design an animation clip for each action of the virtual object, thereby increasing the authenticity of the game.
