[0032] Figure 2 is an exemplary flowchart of a method for processing information of a virtual character provided according to some embodiments of the present application.

In some embodiments, the method 200 for processing information of the virtual character may be automatically started or started by an instruction. The instruction may include a system instruction, a device instruction, a user instruction, an action instruction, etc., or a combination of several.

[0033] In 201, obtain the first medium environment of the virtual character, as well as the trigger action and process action in the first medium environment. Operation 201 can be implemented through the control terminal 120, user terminal 130, and server 140 of the information processing system 100 of the virtual character. In some embodiments, the control terminal 120 and / or the server 140 can obtain the first medium environment of the virtual character, and obtain the trigger action and process action of the virtual character in the first medium environment through the user terminal 130. In some embodiments, the user terminal 130 can cause the virtual character to enter the trigger action, process action, etc. according to user input. As an example, the virtual character can include, but is not limited to, an animated character, a game character, a representative character of the user in the virtual world, etc. For another example, in a virtual reality game scenario, the user himself can be a representative character of the virtual character in the real world. In some embodiments, the medium environment can include environments with different medium attributes, and the medium attributes can include the presence or absence of a medium, medium composition, medium density, etc. As an example, the medium environment can include, but is not limited to, a vacuum medium environment, an atmospheric medium environment, a land medium environment, a water medium environment, a wetland medium environment, a desert medium environment, etc. In some embodiments, the first medium environment can be an atmospheric medium environment. The trigger action can include the initial action of the virtual character leaving the first medium environment. The process action can include the process action of the virtual character in the first medium environment.

[0034] According to some embodiments of the present application, when the virtual character is in the atmospheric medium environment, it can act at the interface between the atmospheric medium environment and the land medium environment. In some embodiments, the virtual character can leave the atmospheric medium environment through a trigger action, and the trigger action can include a takeoff action, and the takeoff action can be realized by means of the land medium environment. In some embodiments, after the virtual character executes the takeoff action by means of the land medium environment, it can execute a process action in the atmospheric medium environment, and the process action can include a falling action. For another example, when the first medium environment is a vacuum, the process action of the virtual character can include a floating action, etc. The process action of the virtual character in the first medium environment can produce corresponding change effects based on the medium attributes of the medium environment.

[0035] At 202, according to the first position of the triggering action, a first object within a preset area is detected and a first distance is calculated. Operation 202 can be implemented by the control terminal 120, the user terminal 130, and the server 140 of the information processing system 100 of the virtual character. In some embodiments, the control terminal 120 and / or the server 140 can detect a first object within a preset area and calculate a first distance based on the first position of the triggering action input by the user terminal 130. As an example, the first position may include position information such as the position where the virtual character performs the triggering action, for example, the position space coordinate values X1Y1Z1. In some embodiments, the preset area may include a preset distance range of the virtual character. For example, the preset distance range includes an interval range with a distance of 0 to a (preset distance) from the virtual character (position space coordinate values X1Y1Z1), and the preset area may include the position space coordinate area (X1±a)(Y1±a)(Z1±a). The first object may include other virtual characters, NPCs (Non-Player Characters), still objects (such as stones), non-still objects (such as birds), etc. The physical objects may include objects that can produce a collision effect with the virtual character (such as obstacles). The first distance may include the distance information between the first object and the first position of the virtual character. When the first object is a still object, the first distance information can be determined according to the distance between the first position and the still object. When the first object is a non-still object, another virtual character, or an NPC, the first distance information can be updated in real time according to the coordinate position information of the first position and the changing first object.

[0036] According to some embodiments of the present application, the detecting a first object within a preset area and calculating a first distance specifically includes: detecting whether there is a first object within the preset distance range of the virtual character; when the current environment is in a second state (the first state is that there is no first object in the current environment, and the second state is that there is a first object in the current environment), calculating the first distance between the virtual character and the first object; the first distance may include the distance between the virtual character at the first position and the first object; when there are at least two first objects, comparing the at least two distance information, and updating the trajectory information according to preset conditions, the trajectory information including a first trajectory, a second trajectory, and a third trajectory.

[0037] According to some embodiments of the present application, when the virtual character performs a takeoff action, the control terminal 120 can obtain the takeoff position information of the virtual character and detect whether there are obstacles within a preset area of 2 meters around the virtual character. If there are obstacles (such as a rock, a bird, etc.), calculate the distance between the takeoff position of the virtual character and the rock, and the distance to the bird, etc. Further, according to the distance comparison information and preset conditions, update the takeoff trajectory of the takeoff action.

[0038] In 203, when the current environment is in the first state, the virtual character enters the process action according to the first trajectory. Operation 203 can be implemented by the control terminal 120 and the server 140 of the information processing system 100 of the virtual character. In some embodiments, according to the detection result, when the current environment is in the first state, the control terminal 120 and / or the server 140 can control the virtual character to enter the process action according to the first trajectory. As an example, the first trajectory may include trajectory information corresponding to the trigger action.

[0039] According to some embodiments of the present application, in the takeoff action, when there are no obstacles within the preset area for the virtual character, the virtual character can enter the process action according to the preset takeoff trajectory. For example, in an atmospheric medium environment, the virtual character enters the falling action according to the takeoff trajectory.

[0040] In 204, according to the second position of the process action, detect the first object within the preset area and calculate the second distance. Operation 204 can be implemented by the server 140 and / or the control terminal 120 of the information processing system 100 of the virtual character. In some embodiments, the server 140 and / or the control terminal 120 can detect the first object within the preset area and calculate the second distance according to the second position of the process action. As an example, the second position may include the position information where the virtual character is located when performing the process action, such as the position space coordinate values X2Y2Z2. In some embodiments, the process action may include a process action within a certain time interval, and the position information corresponding to the process action is position information that changes with time, such as the position space coordinate values X2Y2Z2(Ti). The second distance may include the distance information between the first object and the second position of the virtual character. The second distance information can be updated in real time according to the coordinate position information of the second position changing with time and the coordinate position information of the first object changing.

[0041] According to some embodiments of the present application, detecting the first object in the preset area and calculating the second distance specifically include: detecting whether there is a first object within the preset distance range of the virtual character; when the current environment is in the second state, calculating the second distance between the virtual character and the first object; the second distance may include the distance between the virtual character at the second position and the first object; when there are at least two first objects, comparing the at least two distance information, and updating the trajectory information according to the preset conditions, where the trajectory information includes a second trajectory and a third trajectory.

[0042] According to some embodiments of the present application, when the virtual character performs a falling action, the control terminal 120 can obtain the falling position information of the virtual character changing with time, and detect whether there are obstacles within a preset area of 2 meters around the virtual character. If there are obstacles (such as stones, birds, etc.), calculate the distance between the real-time falling position of the virtual character and the stone, and the distance between the virtual character and the bird, etc. Further, according to the distance comparison information and the preset conditions, update the falling trajectory of the falling action.

[0043] In 205, when the current environment is in the first state, the virtual character performs an intervention action of entering the second medium environment according to the second trajectory. Operation 205 can be implemented by the control terminal 120, the user terminal 130, and the server 140 of the information processing system 100 of the virtual character. In some embodiments, according to the detection result, when the current environment is in the first state, the control terminal 120 and / or the server 140 can control the virtual character to perform an intervention action of entering the second medium environment according to the second trajectory. As an example, the second trajectory may include trajectory information corresponding to the process action. In some embodiments, the second medium environment may include a medium environment with different medium properties from the first medium environment, for example, a water medium environment, etc.

[0044] According to some embodiments of the present application, during the falling motion, when there is no obstacle within the preset area for the virtual character, the virtual character can enter the intervention motion in the second medium environment according to the preset falling trajectory. For example, in the atmospheric medium environment, the virtual character enters the water entry motion in the second medium environment (e.g., the water medium environment) according to the falling trajectory. In some embodiments, the intervention motion of the virtual character is updated according to the temperature parameter of the medium environment. As an example, when the second medium environment is the water medium environment, it is determined whether the temperature parameter of the current medium environment is less than or equal to the freezing point. If the temperature parameter is less than or equal to the freezing point and the second medium environment is currently in a frozen state, the frozen state of the second medium environment, including the ice layer thickness, ice layer hardness, ice layer load-bearing capacity, etc., can be simulated according to the temperature parameter, and the water entry trajectory of the water entry motion, etc., is updated according to the frozen state. The freezing point is the temperature at which a crystal changes from a liquid state to a solid state. As an example, when the ice layer thickness is greater than 15 cm and / or it can bear at least 50 kg per 10 square meters, the virtual character cannot execute the water entry trajectory into the second medium environment. Another example is that when the input information of the player is obtained and an ice hole is opened in the frozen state, the virtual character can integrate information such as the preset water entry trajectory and the ice hole direction trajectory, etc., and execute the water entry motion according to the updated water entry trajectory. Further, the displayed animation can be changed according to the impact attribute of the virtual character and the frozen second medium environment.

[0045] At 206, according to the third position of the intervention motion, the first object within the preset area is detected and the third distance is calculated. Operation 206 can be implemented by the control end 120 and the server 140 of the information processing system 100 of the virtual character. In some embodiments, the control end 120 and / or the server 140 can detect the first object within the preset area and calculate the third distance according to the third position of the intervention motion. As an example, the third position may include the position information where the virtual character is located when performing the intervention motion, etc., for example, the position space coordinate values X3Y3Z3. When the first object is a static object, the third distance information can be determined according to the distance between the third position and the static object. When the first object is a non-static object, another virtual character or an NPC, the third distance information can be updated in real time according to the changing coordinate position information between the third position and the first object.

[0046] According to some embodiments of the present application, detecting the first object within the preset area and calculating the third distance specifically includes: detecting whether there is a first object within the preset distance range of the virtual character; when the current environment is in the second state, calculating the third distance between the virtual character and the first object; the third distance may include the distance between the virtual character at the third position and the first object; when there are at least two first objects, comparing the at least two distance information, and updating the trajectory information according to the preset conditions, where the trajectory information includes the third trajectory.

[0047] According to some embodiments of the present application, when the virtual character performs a water entry action, the control terminal 120 can obtain the water entry position information of the virtual character and detect whether there are obstacles within a preset area of 2 meters around the virtual character. If there are obstacles (such as stones, birds, etc.), calculate the distance between the water entry position of the virtual character and the stone, and the distance from the bird, etc. Further, according to the distance comparison information and the preset conditions, update the water entry trajectory of the water entry action.

[0048] In 207, when the current environment is in the first state, the virtual character performs an exit action to leave the second medium environment according to the third trajectory, and the third trajectory includes the exit direction of the exit action. Operation 207 can be implemented by the control terminal 120 and the server 140 of the information processing system 100 of the virtual character. In some embodiments, according to the detection result, when the current environment is in the first state, the control terminal 120 and / or the server 140 can control the virtual character to perform an exit action to leave the second medium environment according to the third trajectory, and the third trajectory includes the exit direction of the exit action. The third trajectory may include trajectory information corresponding to the exit action. In some embodiments, the second medium environment may include a medium environment with different medium properties from the first medium environment, for example, a water medium environment, etc.

[0049] According to some embodiments of the present application, if there is no first object within the preset distance range of the virtual character, randomly output the exit direction; if there is a first object within the preset distance range of the virtual character, output the corresponding exit direction according to the distance information; if there are at least two first objects within the preset distance range of the virtual character, output the corresponding exit direction according to the comparison information of the distances and the preset conditions, and the preset conditions may include user input information, associated information of the virtual character, etc. As an example, Figure 3As shown, when the preset condition of the virtual character is a time limit (for example, the shortest time to exit the water medium environment, etc.), the virtual character updates the water exit direction to O→A according to the comparison result that the distance OA is less than the distance OB. For another example, when the preset condition of the virtual character is a target limit (for example, the target of exiting the water medium environment is to delay the water exit process, etc.), the virtual character updates the water exit direction to O→B according to the comparison result that the distance OB is greater than the distance OA.

[0050] In some embodiments, the control terminal 120 and / or the server 140 may obtain the internal cause information of the virtual character and output the corresponding water exit direction according to the internal cause information. The internal cause information of the virtual character may include the initial velocity of the triggering action, and the corresponding water exit direction is output according to the initial velocity of the triggering action.

[0051] In some embodiments, the control terminal 120 and / or the server 140 may obtain the external cause information of the virtual character and output the corresponding water exit direction according to the external cause information.

The intervention information may include, but is not limited to, impact attribute information, etc.

[0052] According to some embodiments of the present application, the control terminal 120 and / or the server 140 may determine whether the real-time position coordinates XtYtZt of the virtual character belong to the spatial coordinate interval XijYijZij according to the obtained interval XijYijZij of the second medium environment space coordinates. When the real-time position coordinates XtYtZt of the virtual character belong to the spatial coordinate interval XijYijZij, it is determined that the virtual character enters the second medium environment.

[0053] According to some embodiments of the present application, during the process from the intervention action to the water exit action, when there is no obstacle in the preset area for the virtual character, the virtual character may perform the water exit action of leaving the second medium environment according to the preset water exit trajectory. For example, in a water medium environment, the virtual character performs the water exit action of leaving the second medium environment (for example, the water medium environment) according to the water exit trajectory. The water exit trajectory includes the water exit direction of the water exit action. As an example, when it is determined that the virtual character enters the second medium environment, the intervention point where the virtual character enters the second medium environment may be further determined, the distances between the intervention point and the boundaries of the second medium environment in each direction are judged, and the water exit trajectory of the water exit action is updated according to the distance comparison information and the preset conditions.

Operation 208 can be implemented by the control terminal 120 and the server 140 of the information processing system 100 of the virtual character. In some embodiments, when the current environment is in the second state and an impact occurs with the virtual character, the control terminal 120 and / or the server 140 can update the first trajectory, the second trajectory, and the third trajectory according to the impact attributes of the virtual character and the first object, and display the animation of the virtual character according to the updated trajectory information. In some embodiments, the impact attributes may include, but are not limited to, impact mass, impact speed, impact direction, etc. The control terminal 120 and / or the server 140 can calculate and update the trajectory information according to impact attributes such as impact mass and impact speed.

For example, an intervention animation sub-segment (such as an entering water animation), an exit animation sub-segment (such as an exiting water animation), etc.

[0057] In some embodiments, process 200 may further preset the trajectory information of the virtual character in different actions through a state machine.

As an example, when the virtual character is hit by other characters during the take-off process, the take-off trajectory can be updated by changing the take-off direction of the take-off trajectory, etc. Another example, when the virtual character is hit by a bird during the falling process, the falling trajectory can be updated by changing the falling direction of the falling trajectory, etc. Another example, when the environmental state of the virtual character during the falling process is a heavy rain, the falling trajectory can be updated by changing the falling speed of the falling trajectory, etc. Another example, when the virtual character is hit by a stone during the water-entry process, the water-entry trajectory can be updated by changing the water-entry point of the water-entry trajectory, etc. Another example, when the virtual character obtains the force parameter of the user input system during the water-exit process, the water-exit trajectory can be updated by changing the water-exit point of the water-exit trajectory, etc.

In some embodiments, process 200 may update the weight of the state machine for changing the animation parameters according to the input information of the user. As an example, by presetting different weights for the input information, position information, first object information, internal factor information, external factor information, etc. of the user, the state machine may fuse the preset trajectory and different-direction trajectories generated according to different weight information to update the animation of the virtual character. The external factor information may include impact attributes, force field information, etc.

[0060] Figure 3It is a horizontal schematic diagram for calculating distance according to the information processing method of a virtual character provided by some embodiments of the present application. As Figure 3 shown, the intervention action of the virtual character entering the second medium environment may include an intervention point, and the intervention point is the intersection point where the virtual character intervenes at the interface between the second medium environment and the first medium environment. As an example, when the second medium environment is a water medium environment, the intervention point of the virtual character is the water entry point, and the water entry point is the intersection point of the horizontal plane where the virtual character dives into the water medium environment. In some embodiments, taking the interface between the second medium environment and the first medium environment as the reference horizontal plane (in Figure 3 the horizontal schematic diagram, the reference horizontal plane is indicated by the reference horizontal line AOB of the cross-section), a vertical line is drawn from the position of the first object to the reference horizontal line, and the intersection point of the vertical line and the reference horizontal line is the position point of the first object, and the distance between the intervention point and the position point is calculated. As an example, when there are at least two first objects, the first objects may include object A and object B. A vertical line A is drawn from the position of object A to the reference horizontal line, and a vertical line B is drawn from the position of object B to the reference horizontal line. The position points where the vertical line A and the vertical line B intersect with the reference horizontal line are position point A and position point B respectively. The distance OA between the water entry point O and position point A, and the distance OB between the water entry point O and position point B are calculated, and the distance OA and the distance OB are compared, and the trajectory information of the virtual character is updated according to the comparison result.

[0061] In some embodiments, the trajectory information of the virtual character may include an exit direction (for example, the exit direction in the water medium environment). As an example, when the preset condition of the virtual character is a time limit (for example, the shortest time-consuming to exit the water medium environment, etc.), the virtual character updates the exit direction to O→A according to the comparison result that the distance OA is less than the distance OB. Another example is that when the preset condition of the virtual character is a target limit (for example, the target of exiting the water medium environment is to delay the water exit process, etc.), the virtual character updates the exit direction to O→B according to the comparison result that the distance OB is greater than the distance OA.

In some embodiments, a horizontal axis and a vertical axis coordinate system can be established centered on the first object (any object, such as an obstacle, etc.) around the character, and multi - directional rays are drawn from the first object around the character to the four quadrants of the coordinate system to detect the distance between the character and the first object around it.
