Description

Technical Field

[0001] The present application relates to the field of game development technology, and in particular to a method, device, and electronic device for action interaction of a virtual character in a game scene. Background Art

[0002] Customizing the body shape of virtual characters in games has always been a topic of great interest to players. With the continuous advancement of gaming technology, more and more games are offering the ability to customize the body shape of virtual characters, allowing players to adjust parameters such as height, shoulder width, and leg length to their preferences, making the body shape of the virtual character more suitable for the player. This not only satisfies players' pursuit of aesthetics but also increases game playability and immersion.

[0003] However, existing technologies for implementing interactive virtual character movements require pre-designed animations based on the fixed body shapes of the virtual characters. For example, to implement a handshake between an adult character, another adult character, and a child character, a set of handshake animations between the adults and another between the adult and the child must be pre-designed. Furthermore, if the body shape of one of the virtual characters changes, the handshake animations must be redesigned, resulting in high game development costs and limited flexibility.

[0051] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0052] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0053] In order to solve the problem in the prior art that when realizing the action interaction of virtual characters, it is necessary to design the interactive animation in advance according to the fixed body shape of the virtual characters, resulting in high game development costs and low flexibility, the present application provides a method, device and electronic equipment for the action interaction of virtual characters in a game scene, which can reduce the cost of game development and improve the flexibility of game resources.

[0054] See also Figure 1 , Figure 1This is a flow chart of a method for interactive action of a virtual character in a game scene provided by an embodiment of the present application. Figure 1 As shown, the action interaction method of the virtual character in the game scene may include the following steps:

[0055] Step 101: Receive a target action interaction request sent by a first virtual character to a second virtual character, wherein the first virtual character and the second virtual character are different virtual characters in the same game scene, and the body parameters of the first virtual character and the second virtual character are customized by game players or pre-configured.

[0056] Specifically, the first virtual character and the second virtual character can be different virtual characters in the same game scene. They can be player characters in the game application (i.e., the body shape of the character can be customized by the game player) or non-player characters in the game application (i.e., the body shape of the character is pre-configured in the game application and cannot be adjusted at will). The target action interaction request is used to request the second virtual character to complete a target interaction action with the first virtual character, such as a handshake, kiss, hug, or other interaction action.

[0057] In this step, when the first virtual character wants to complete the target interaction action with the second virtual character, the first virtual character can send a target action interaction request to the second virtual character, requesting the second virtual character to complete the target interaction action with the first virtual character. It should be noted that the second virtual character in the embodiment of the present application can be one virtual character or multiple virtual characters. For example, when character A sends handshake action requests to character B and character C at the same time, the first virtual character is character A, and the second virtual characters are character B and character C.

[0058] Step 102: In response to the target action interaction request, obtain a first position corresponding to a first sampling point of the first virtual character and a second position corresponding to a second sampling point of the second virtual character, wherein the first sampling point is a skeletal part of the first virtual character that contacts the second virtual character when completing the target interaction action, and the second sampling point is a skeletal part of the second virtual character that contacts the first virtual character when completing the target interaction action.

[0059] Specifically, the first sampling point is the skeletal part where the first virtual character and the second virtual character come into contact when completing the target interaction action, and the second sampling point is the skeletal part where the second virtual character and the first virtual character come into contact when completing the target interaction action. For example, when the target interaction action between the first and second virtual characters is a handshake, the first sampling point is the hand skeleton of the first virtual character, and the second sampling point is the hand skeleton of the second virtual character. When the target interaction action between the first and second virtual characters is a kiss, the first sampling point is the head skeleton of the first virtual character, and the second sampling point is the head skeleton of the second virtual character, and so on.

[0060] In this step, after receiving the target action interaction request sent by the first virtual character to the second virtual character, in response to the target action interaction request, a first sampling point of the first virtual character and a second sampling point of the second virtual character can be determined according to the type of the target interaction action requested by the target action interaction request, and then the first sampling point of the first virtual character and the second sampling point of the second virtual character can be directly sampled according to the positions of the first virtual character and the second virtual character in the game screen to obtain a first position corresponding to the first sampling point of the first virtual character and a second position corresponding to the second sampling point of the second virtual character; or the first virtual character and the second virtual character can be controlled to perform action interaction according to a preset standard interaction animation, and the first virtual character and the second virtual character can be controlled to stop the action interaction when reaching a marked frame of the standard interaction animation, and then the first position is determined according to the stop position of the first sampling point in the marked frame, and the second position is determined according to the stop position of the second sampling point.

[0061] Step 103: Determine actual interaction point positions of the first sampling point and the second sampling point according to the first position and the second position.

[0062] Specifically, the actual interaction point location refers to the interaction location between the first sampling point of the first virtual character and the second sampling point of the second virtual character when performing the target interaction action. For example, in a handshake, the first sampling point is the hand skeleton of the first virtual character, and the second sampling point is the hand skeleton of the second virtual character. The actual interaction point location is the point where the palms of the two parties meet. As an alternative embodiment, the actual interaction point location can be the midpoint between the first sampling point and the second sampling point, or a position near the midpoint.

[0063] Step 104: Adjust the positions and rotation angles of the first sampling point and the second sampling point based on the actual interaction point positions and pre-recorded target interaction information, where the target interaction information is the relative distance information and relative rotation angle information between the sampling point and the interaction point when two virtual characters of the same size complete the target interaction action.

[0064] Specifically, the target interaction information is obtained based on a pre-created standard interaction animation. This standard interaction animation refers to the animation of a virtual character performing a target interaction action with a character of the same size. To obtain the target interaction information, the animation file for the standard interaction animation can be simultaneously called and played for two virtual characters of the same size. The relative distance and rotation angle between the sampling point and the interaction point when the two virtual characters of the same size complete the target interaction action are then recorded and used as the target interaction information.

[0065] In this step, after obtaining the actual interaction point position, the position and rotation angle of the first sampling point and the second sampling point can be adjusted according to the actual interaction point position and the pre-recorded target interaction information, so that the first sampling point and the second sampling point can meet the execution conditions for completing the target interaction action.

[0066] Step 105 : Based on the information of the adjusted first sampling point and the second sampling point, the whole body skeleton positions of the first virtual character and the second virtual character are determined respectively, and a game performance of the target interactive action is generated according to the whole body skeleton positions.

[0067] In this step, after determining the adjusted position and rotation angle of the first sampling point, as well as the position and rotation angle of the second sampling point, the full body skeletons of the first virtual character and the second virtual character can be matched to corresponding positions using inverse kinematics (IK), thereby obtaining the full body skeleton positions of the first virtual character and the second virtual character. The game application can then generate a game performance of the target interactive action based on the full body skeleton positions of the first virtual character and the second virtual character, such as generating a game screen of the first virtual character and the second virtual character shaking hands or kissing.

[0068] In this embodiment, the actual interaction point locations of the first and second sampling points when performing a target interaction action can be determined based on the first position corresponding to the first sampling point of the first virtual character and the second position corresponding to the second sampling point of the second virtual character. Furthermore, the full-body skeletal positions of the first and second virtual characters can be determined based on these actual interaction point locations to achieve the game performance of the target interaction action between the first and second virtual characters. This eliminates the need to redesign new interaction animations even if the body shapes of the first and second virtual characters change, thereby reducing game development costs and increasing the flexibility of game resources.

[0069] Furthermore, the above step 102, obtaining a first position corresponding to a first sampling point of the first virtual character and a second position corresponding to a second sampling point of the second virtual character, specifically includes:

[0070] respectively controlling the first and second virtual characters to perform an action interaction according to a preset standard interaction animation, and controlling the first and second virtual characters to stop the action interaction when reaching a marked frame of the standard interaction animation, wherein the standard interaction animation is an interaction animation pre-created based on the interaction process of virtual characters of the same body type when completing a target interaction action, and the marked frame is a video frame corresponding to the moment when the virtual characters begin the action interaction in the standard interaction animation;

[0071] The staying position of the first sampling point in the marked frame is determined as the first position, and the staying position of the second sampling point in the marked frame is determined as the second position.

[0072] Specifically, the standard interaction animation is pre-created based on the interaction process of a virtual character of the same body type completing the target interaction action. For example, if the target interaction action is a handshake, the standard interaction animation is an animation of an arm swinging horizontally up and down. The marked frame of this standard interaction animation can be the frame where the arm is exactly horizontal.

[0073] In one embodiment, after receiving a target action interaction request sent by a first virtual character to a second virtual character, in response to the target action interaction request, a first sampling point of the first virtual character and a second sampling point of the second virtual character can be determined according to the type of the target interaction action requested by the target action interaction request, and then the first virtual character and the second virtual character are controlled to perform action interaction according to a preset standard interaction animation, and when the mark frame of the standard interaction animation is reached, the first virtual character and the second virtual character are controlled to stop the action interaction, and then the first sampling point and the second sampling point are sampled, and the stop position of the first sampling point in the mark frame is determined as the first position, and the stop position of the second sampling point is determined as the second position.

[0074] In this way, by sampling the first sampling point and the second sampling point respectively when the first virtual character and the second virtual character perform the standard interactive animation, the distance between the first sampling point and the second sampling point can be obtained without any interference, which makes it convenient to subsequently select the interactive animation corresponding to the first virtual character and the second virtual character from the preset interactive animation set based on the distance between the two to determine the actual interaction point position.

[0075] Furthermore, the above step 103, determining the actual interaction point positions of the first sampling point and the second sampling point based on the first position and the second position, includes:

[0076] determining, based on the first position and the second position, a distance between the first sampling point and the second sampling point in a target direction, wherein the target direction is consistent with a contact direction of the first sampling point and the second sampling point when completing the target interaction action;

[0077] According to the distance, a first interactive animation is matched for the first virtual character from a preset interactive animation set, and a second interactive animation is matched for the second virtual character, wherein the distance between the sampling point in the first interactive animation and the sampling point in the second interactive animation is the smallest, and the standard interactive animation belongs to the interactive animation set;

[0078] Adjusting the first sampling point from the first position to the third position according to the first interactive animation, and adjusting the second sampling point from the second position to the fourth position according to the second interactive animation;

[0079] A midpoint position between the third position and the fourth position is determined as the actual interaction point position.

[0080] Specifically, the aforementioned interactive animation set includes not only standard interactive animations but also non-standard interactive animations. Continuing with the handshake example, non-standard interactive animations could include a slightly raised arm handshake animation or a slightly lowered arm handshake animation. The target direction refers to the contact direction between the first and second sampling points when completing the target interactive action. Since the avatar's height is the most influential body parameter on the target interactive action, for most target interactive actions, the target interactive direction is vertical.

[0081] In one embodiment, when determining the actual interaction point location of a first sampling point and a second sampling point, the distance between the first sampling point and the second sampling point in the target direction can be first determined based on the first and second positions. Then, based on the obtained distance, a first interaction animation is matched for the first virtual character and a second interaction animation is matched for the second virtual character from a preset interaction animation set. Taking a handshake action as an example, if the vertical distance between the hand bones of the first and second virtual characters extending their arms is similar, it indicates that the first and second virtual characters have similar body shapes, and in this case, the first and second virtual characters are matched with a standard handshake animation. If the vertical distance between the hand bones of the first and second virtual characters extending their arms exceeds a preset threshold, the handshake animation with the arm extended downward is played for the hand with the higher hand bone, and the handshake animation with the arm extended upward is played for the hand with the lower hand bone. In this way, the first sampling point can be adjusted from the first position to the third position based on the first interaction animation, and the second sampling point can be adjusted from the second position to the fourth position based on the second interaction animation. The midpoint between the third and fourth positions is then determined as the actual interaction point location.

[0082] Through the above method, corresponding interaction animations can be matched for the first virtual character and the second virtual character from the preset interaction animation set, so that the distance between the first sampling point and the second sampling point is minimized without interference. This not only reduces the distance between the first sampling point and the second sampling point during subsequent adjustment, but also allows the interaction animation of each virtual character to adapt to its body shape, making the movements of the first virtual character and the second virtual character more vivid and realistic when performing target actions in interaction.

[0083] Furthermore, the above step 104, adjusting the position and rotation angle of the first sampling point and the second sampling point based on the actual interaction point position and the pre-recorded target interaction information, includes:

[0084] Obtaining target interaction information, wherein the target interaction information is determined based on sampling points and interaction points of virtual characters of the same body shape in the marked frame;

[0085] Determine, based on the target interaction information, an actual relative distance and an actual relative rotation angle between a first sampling point and an actual interaction point position, and an actual relative distance and an actual relative rotation angle between a second sampling point and the actual interaction point position for completing the target interaction action;

[0086] The positions and rotation angles of the first sampling point and the second sampling point are adjusted according to the actual relative distance and the actual relative rotation angle between the first sampling point and the actual interaction point position, and the actual relative distance and the actual relative rotation angle between the second sampling point and the actual interaction point position.

[0087] Specifically, the target interaction information refers to information determined based on the sampling points and interaction points of virtual characters of the same body shape in the marked frame. The target interaction information may include information such as the relative distance and relative rotation angle between the sampling point and the interaction point.

[0088] In one embodiment, when adjusting the position and rotation angle of the first sampling point and the second sampling point, it is necessary to first obtain target interaction information. Then, based on the target interaction information, the actual relative distance and actual relative rotation angle between the first sampling point and the actual interaction point position, as well as the actual relative distance and actual relative rotation angle between the second sampling point and the actual interaction point position, are determined to complete the target interaction action. Then, based on the actual relative distance and actual relative rotation angle between the first sampling point and the actual interaction point position, as well as the actual relative distance and actual relative rotation angle between the second sampling point and the actual interaction point position, the positions and rotation angles of the first sampling point and the second sampling point are adjusted. In this way, it is ensured that the adjusted first sampling point and the second sampling point can cooperate with each other to complete the target interaction action.

[0089] Furthermore, the above step 105, based on the information of the adjusted first sampling point and the second sampling point, respectively determining the full body skeleton positions of the first virtual character and the second virtual character, respectively determining the full body skeleton positions of the first virtual character and the second virtual character, includes:

[0090] Obtaining a first body parameter of the first virtual character and a second body parameter of the second virtual character;

[0091] Based on the adjusted position information of the first sampling point and the first body shape parameter, the whole body skeleton of the first virtual character is matched in sequence according to a preset matching order to determine the position of the whole body skeleton of the first virtual character; and based on the adjusted position information of the second sampling point and the second body shape parameter, the whole body skeleton of the second virtual character is matched in sequence according to a preset matching order to determine the position of the whole body skeleton of the second virtual character.

[0092] Specifically, the first body shape parameter and the second body shape parameter may include but are not limited to parameters such as arm length, torso length, leg length, the position of the shoulder bones relative to the sternum, and the midpoint position of the two kneecaps. The preset matching order can be pre-set according to the type of target interactive action. For example, when the target interactive action is a handshake action, the preset matching order is hand bones-shoulder bones-sternum bones-pelvic bones-torso bones-elbow bones-knee bones; when the target interactive action is a kissing action, the preset matching order is head bones-shoulder bones-sternum bones-pelvic bones-torso bones-limb bones, etc.

[0093] In one embodiment, when determining the full body skeletal position of the first virtual character and the second virtual character, the first body shape parameter of the first virtual character and the second body shape parameter of the second virtual character can be obtained first, and then based on the position information of the adjusted first sampling point and the first body shape parameter, the full body skeleton of the first virtual character is matched in sequence according to a preset matching order to determine the full body skeletal position of the first virtual character, and based on the position information of the adjusted second sampling point and the second body shape parameter, the full body skeleton of the second virtual character is matched in sequence according to a preset matching order to determine the full body skeletal position of the second virtual character. In this way, the game performance of the target interactive action generated based on the full body skeletal position of the first virtual character and the second virtual character can be made more natural and realistic. Taking the handshake action as an example, when the sampling point position of a virtual character is very low, the virtual character can be made to bend its legs and waist to conform to human body movement.

[0094] Furthermore, the preset matching order is to use the adjusted position information of the first sampling point or the adjusted position information of the second sampling point as the matching starting point, and to match the positions of other bones of the first virtual character or the second virtual character in order from near to far.

[0095] In one embodiment, when performing full-body skeleton matching, it can be implemented using the IK method, that is, first using the adjusted position information of the first sampling point or the adjusted position information of the second sampling point as the matching starting point, and then matching the positions of other bones of the first virtual character or the second virtual character in order from near to far. For example, when the target interactive action is a handshake action, the preset matching order is hand bones-shoulder bones-elbow bones and sternum bones-pelvic bones-trunk bones-knee bones. In this way, the game performance of the target interactive action generated according to the full-body skeleton positions of the first virtual character and the second virtual character can be made more natural and realistic. Taking the handshake action as an example, when the sampling point position of a virtual character is very low, the virtual character can be made to bend his legs and bend over to conform to human body movements.

[0096] Furthermore, the first body shape parameter and the second body shape parameter each include arm length, torso length, leg length, the position of the shoulder bones relative to the sternum, and the midpoint position of the two kneecaps;

[0097] The above step 105, matching the entire skeleton of the first virtual character in sequence according to a preset matching order based on the adjusted position information of the first sampling point and the first body shape parameter to determine the entire skeleton position of the first virtual character, includes:

[0098] In a case where the first sampling point is a hand bone of the first virtual character, determining a shoulder bone position of the first virtual character according to the arm length;

[0099] Determining the position of the sternum of the first virtual character based on the position of the shoulder bones of the first virtual character and the position of the shoulder bones relative to the sternum, and determining the position of the elbow bones of the first virtual character based on the position of the shoulder bones of the first virtual character and the position of the hand bones of the first virtual character;

[0100] determining a pelvic position of the first avatar according to a midpoint between a sternum position and both kneecap positions of the first avatar;

[0101] The torso bone position of the first virtual character is determined according to the sternum position, pelvic position and torso length of the first virtual character, and the knee bone position of the first virtual character is determined according to the pelvic position and leg length of the first virtual character.

[0102] In one embodiment, when the first sampling point is the hand skeleton of the first virtual character, that is, the target interactive action is a handshake action, it can be determined whether the distance from the hand skeleton to the shoulder skeleton exceeds the length of the arm. If the distance from the hand skeleton to the shoulder skeleton exceeds the length of the arm, the position of the shoulder skeleton is moved toward the position of the hand skeleton so that the distance from the hand skeleton to the shoulder skeleton does not exceed the length of the arm. After determining the position of the shoulder skeleton, the position of the sternum can be determined based on the position of the shoulder skeleton and the position of the shoulder skeleton relative to the sternum. In addition, the position of the elbow skeleton can be calculated using the TwoBoneIK algorithm (i.e., an inverse kinematics solution algorithm applicable to two-dimensional and three-dimensional skeletal systems) with the hand skeleton as the target skeleton, the elbow skeleton as the action skeleton, and the shoulder skeleton as the root skeleton. After determining the position of the sternum, the position of the pelvis can be calculated using the TwoBoneIK algorithm with the sternum as the target skeleton, the midpoint of the position of the two kneecaps as the root skeleton, and the pelvis as the action skeleton. After calculating the position of the pelvis, the position of the torso bones can be calculated using the forward and backward reaching inverse kinematics (FABRIK) algorithm, with the sternum as the target bone and the pelvis as the root bone. After calculating the position of the torso bones, the position of the knee bones can be calculated using the TwoBoneIK algorithm, with the foot bones (which are determined based on the pelvic position and leg length) as the target bones, the knee as the active bone, and the pelvis as the root bone. In this way, the full body skeletal position of the virtual character when performing the target interactive action can be accurately obtained, thereby achieving the target interactive action's game performance.

[0103] In one embodiment, the action interaction process of the virtual character in the game scene provided by the embodiment of the present application is as follows: Figure 2 As shown, it includes a resource preparation phase and an interactive use phase, which may specifically include the following steps:

[0104] Step 201: Set candidate sampling points.

[0105] Multiple candidate sampling points are set up on the virtual character, such as the hand bones, elbow bones, pelvis, knee bones, foot bones, etc. of the virtual character as candidate sampling points.

[0106] Step 202: Create an interactive animation group (ie, the interactive animation set mentioned above).

[0107] Art students will create a set of interactive animations, including standard and non-standard ones. Standard interactive animations are those that can be completed without any interaction, given a standard body type. For example, art students will need to create a standard handshake animation with a virtual character of the same body type, as well as a set of non-standard interactive animations, such as a slightly raised arm handshake animation and a slightly lowered arm handshake animation.

[0108] Step 203: Set up a marker frame.

[0109] Set a marker frame for the standard interactive animation. The marker frame of the handshake animation should be the frame where you extend your hand and shake the other person's hand.

[0110] Step 204: Set the sampling points required for the target interactive action.

[0111] When setting the required sampling points for the target interaction action, you can select from the candidate sampling points mentioned above. The sampling point for the handshake action is the hand bone of the outstretched hand.

[0112] Step 205: Record the relative information between the sampling points and the interaction points in the standard interactive animation (ie, the target interaction information mentioned above).

[0113] Control both virtual characters to play the standard interactive animation and pause until the marked frame. At this time, the two virtual characters can complete the interaction effect. Assume that the midpoint of the sampling points of both virtual characters is the interaction point, and record the relative position and rotation angle of the sampling points of both virtual characters relative to the interaction point, which can also be called interaction position and interaction rotation.

[0114] Step 206: Play the adaptation animation.

[0115] Both avatars play a standard interaction animation and pause until the marked frame. Then, corresponding sampling points are found for both avatars, their positions are calculated, and a matching interaction animation is selected from the interactive animation set. For example, if the hand skeletal positions of both avatars' outstretched hands are similar, both avatars use the standard handshake animation. If the difference in hand skeletal positions exceeds a preset threshold, the handshake animation with the arm extended downwards plays for the avatar with the hand higher up, and the handshake animation with the arm extended upwards plays for the avatar with the hand lower up.

[0116] Step 207: Calculate the actual interaction points between the two virtual characters.

[0117] The midpoint of the sampling points of both virtual characters is taken as the actual interaction point.

[0118] Step 208: Sampling point position matching.

[0119] According to the relative information between the sampling points and the interaction points recorded in step 205 , the positions and rotations of the sampling point skeletons of both virtual characters are adjusted.

[0120] Step 209: Use the full-body IK algorithm to calculate the skeleton positions of both virtual characters.

[0121] In this embodiment, one or a group of animation files can be used to implement the motion interactions between characters of different body types, significantly reducing the workload of motion art and the size of the project package. Furthermore, the player can customize the body type of the character, enabling the motion interactions of the character with the customized body type.
