[0002] In game production, if motion information is added to a character in the game, the height at which the character's leg is lifted can be affected by the terrain where the character is located, that is, the height at which the character's leg is lifted is different under different terrains. If the character's wearable can be adjusted in real time according to the height at which the leg is lifted, the penetration between the wearable and the character in the game animation can be avoided and the performance can be enhanced.

[0029] Embodiment 1

[0030] Figure 1It is a schematic flowchart of an animation generation method provided in the first embodiment of the present invention. This embodiment is applicable to the situation of generating game animation information based on a pre-constructed offline storage resource library. This method can be executed by an animation generation device, which can be implemented in the form of hardware and / or software, and the animation generation device can be configured in an electronic device such as a computer, a tablet, or a mobile phone. As Figure 1 shown, the method includes:

[0031] S110. Obtain the character animation information of the current frame, where the character animation information includes target character information and current scene information.

[0032] Among them, the character animation information can be an animation containing target character information and current scene information. Exemplarily, the character animation information can be a plot animation played in the game, such as an animation of a character triggering a battle; or, it can also be a scene animation shown in the game, such as an animation of a character walking on a hillside.

[0033] Specifically, the purpose of obtaining the character animation information of the current frame in this embodiment is to determine the target character information and the current scene information, so as to further generate the animation information of the next frame according to the target character information and the current scene information.

[0034] Among them, the target character information can be information describing the target character in the character animation information. Optionally, the target character can be a player-controlled character, a rare monster, or a non-player character; the number of target characters can be one or more. Exemplarily, after obtaining the character animation information, a target detection algorithm can be used to determine the target character in the character animation information, and then the target character information corresponding to the target character can be obtained. In this embodiment, the target character information can include a character identifier corresponding to the target character, and can also include attribute information corresponding to the target character, such as weight, body type, and the maximum amplitude of body movements.

[0035] In this embodiment, the current scene information can be information describing the scene included in the character animation information. Specifically, the current scene information can include terrain information. Among them, the terrain information can be information describing the terrain of the scene; for example, the terrain information can include slope information and physical environment simulation information corresponding to the terrain information. The physical environment simulation information can be information describing the physical environment of the terrain, which can include at least one of gravity information, friction information, height information, and wind information.

[0036] S120. According to the target character information and the current scene information, obtain target resource information corresponding to the character animation information from the pre-constructed offline storage resource library, where the target resource information includes character storage animation information and wearable storage animation information corresponding to the target character information and the current scene information.

[0037] In this embodiment, various role animations and wearable animations in various scenarios can be pre-simulated, and the simulated role animation information and wearable animation information are stored in an offline storage resource library. Among them, the simulated role animation information and wearable animation information can be associated and stored with role information and scene information in the offline storage resource library. The wearable animation information can be the animation information of the pendant worn by the role, such as ribbon animation information, headdress animation information, etc.

[0038] Furthermore, when real-time animation needs to be generated, the animation information corresponding to the target role information and the current scene information can be directly queried in the offline storage resource library according to the target role information of the current frame and the current scene information, that is, the role stored animation information and the wearable stored animation information.

[0039] Exemplarily, the simulated animations stored in the offline storage resource library can be in a data format that the engine can quickly recognize; the engine reads the offline storage resource library to obtain the target resource information corresponding to the role animation information of the current frame.

[0040] Specifically, the offline storage resource library can store the simulated animations in a sharded storage manner. For example, in the offline storage resource library, each role corresponds to a data shard, and in a data shard, the simulated animation information of the role corresponding to the data shard in all scenarios is stored. During the process of querying the target resource information, the target data shard corresponding to the target role information can be queried in the offline storage resource library according to the target role information, and then the target resource information corresponding to the current scene information can be queried in the target data shard according to the current scene information, so as to obtain the role stored animation information and the wearable stored animation information corresponding to the target role information and the current scene information.

[0041] Alternatively, in the offline storage resource library, it can also be that each scene corresponds to a data shard, and in a data shard, the simulated animation information of all roles in the scene corresponding to the data shard is stored. During the process of querying the target resource information, the target data shard corresponding to the current scene information can be queried in the offline storage resource library according to the current scene information, and then the target resource information corresponding to the target role information can be queried in the target data shard according to the target role information, so as to obtain the role stored animation information and the wearable stored animation information corresponding to the target role information and the current scene information.

[0042] Through the above sharded storage method, the efficiency of querying the target resource information in the offline storage resource library can be improved, and thus the efficiency of animation generation is improved.

[0043] S130. Generate the animation information for the next frame based on the current scene information, the animation information stored for the character, and the animation information stored for the wearable.

[0044] Specifically, after obtaining the animation information stored for the character and the animation information stored for the wearable, the animation information for the next frame can be generated based on the current scene information, the animation information stored for the character, and the animation information stored for the wearable. Exemplarily, a state machine overlay can be employed to generate the animation information for the next frame to be played based on the current scene information, the animation information stored for the character, and the animation information stored for the wearable.

[0045] In an alternative embodiment, generating the animation information for the next frame based on the current scene information, the animation information stored for the character, and the animation information stored for the wearable can also be: obtaining the real-time weather information and generating the animation information for the next frame based on the real-time weather information, the current scene information, as well as the character animation information and the wearable animation information.

[0046] Among them, the real-time weather information can be the information describing the current weather in the character animation information of the current frame, and it can be determined according to the character animation information of the current frame. For example, the real-time weather information corresponding to the character animation information can be determined according to the character animation information of the current frame.

[0047] Specifically, the animation information for the next frame can be generated based on the real-time weather information, the current scene information, the character animation information, and the wearable animation information to obtain the next frame animation combined with the real-time weather of the current frame. For example, generate the next frame animation containing rain.

[0048] In this alternative embodiment, considering the influence of the real-time weather on the animation display effect, the animation information for the next frame is further generated in combination with the real-time weather information, improving the display effect of the generated animation.

[0049] The technical solution of this embodiment obtains the character animation information of the current frame to obtain the target character information and the current scene information, and then, according to the target character information and the current scene information, obtains the target resource information from the pre-constructed offline storage resource library to obtain the animation information stored for the character and the animation information stored for the wearable, and then generates the animation information for the next frame based on the current scene information, the animation information stored for the character, and the animation information stored for the wearable, realizing the animation generation based on the offline storage resource library. This method generates animations by querying offline resources, solving the technical problem of excessive resource consumption during real-time calculation. Moreover, by querying offline resources to obtain the pre-generated animation information, it solves the technical problem of low animation accuracy generated during real-time calculation, and can generate high-quality animations simply and quickly while saving resources.

[0050] Embodiment Two

[0051] Figure 2 This is a schematic flowchart of an animation generation method provided in the second embodiment of the present invention. On the basis of the above embodiments, this embodiment supplements the process of constructing an offline storage resource library. As Figure 2 shown, the method includes:

[0052] S210. Obtain the original animation information of the target animation character, and determine the animation parameter configuration information corresponding to the original animation information. Among them, the original animation information includes character bone information and animation information of the character bone information. The character bone information includes character body bone information, binding information between the character body bone and the skin, and character wearable bone information.

[0053] Among them, the target animation character can be a pre-constructed character that can be used to generate corresponding animations. Exemplarily, the target animation character can be a player-controlled character, a non-player character, or a game monster in the game. The original animation information can be the character bone information and animation information constructed for the target animation character. Specifically, the character bone information can be the character body bone information, the character wearable bone information, and the binding information between the character body bone and the skin.

[0054] Among them, the character body bone information can be information describing the key points of the character body bones of the target animation character; the character wearable bone information can be information describing the key points of the bones of the wearables of the target animation character; the binding information between the character body bone and the skin can be information describing the binding between the character body bone and the skin of the target animation character.

[0055] It should be noted that the original animation information in this embodiment does not include the animation information of the character wearables. In other words, in this embodiment, it is not necessary to construct the animation information of the character wearables of the target animation character. Compared with the solution that needs to construct the animation information of the character body bones and the animation information of the character wearables, the action production cost can be reduced.

[0056] Specifically, the character bone information and the animation information of the character bone information can be constructed in computer image software. That is, obtaining the original animation information of the target animation character can be: obtaining the original animation information of the target animation character constructed based on computer image software. Among them, the computer image software can be DDC (Digital Content Creation) software.

[0057] Optionally, the original animation information of the target animation character constructed based on computer image software can be stored in a file format that can be read by the engine, and then the engine can read the original animation information from the file exported by the computer image software.

[0058] In this embodiment, the animation parameter configuration information may include the first attribute configuration information corresponding to the target animation character and the second attribute configuration information corresponding to the wearable. Exemplarily, the first attribute configuration information may include the maximum amplitude of the body movement of the target animation character, or may further include the weight and body shape of the target animation character; the second attribute configuration information may include the material of the wearable.

[0059] Optionally, the animation parameter configuration information may be set by the user on the display interface of the engine, or may be automatically determined according to the character bone information. Exemplarily, the maximum amplitude of the body movement may be determined according to the character body bone information in the character bone information, and the material of the wearable may be determined according to the character wearable bone information.

[0060] S220. Based on the animation parameter configuration information, the animation information of the character body bones, and the character bone information, simulate the character simulation animation information and the wearable simulation animation information of the target animation character under the animation scene information.

[0061] Specifically, according to the animation parameter configuration information, the character bone information, and the animation information of the character body bones, physical simulation operations may be performed through the engine to simulate the character simulation animation information and the wearable simulation animation information of the target animation character under various animation scene information, so as to obtain the animation data considering the first attribute configuration information of the target animation character, the second attribute configuration information of the wearable, the character bone information of the target animation character, and the animation scene information.

[0062] It should be noted that in this embodiment, it is not necessary to pre-construct the animation information of the wearable of the target animation character. Through the above method, the character simulation animation information and the wearable simulation animation information of the target animation character under various animation scene information can be generated, reducing the animation production cost.

[0063] Optionally, during the process of generating the character simulation animation information and the wearable simulation animation information of the target animation character in various scenarios, the collision information between the character body bones and the character wearable bones may be further introduced to further avoid the penetration between the character body and the character wearable in the generated animation.

[0064] For example, based on the animation parameter configuration information, the animation information of the character's body bones, and the character bone information, simulating the character simulation animation information and the wearable simulation animation information of the target animation character under the animation scene information may be: adding pre-set bone collision information corresponding to the character bone information to the character body bone information and the character wearable bone information in the character bone information; based on the character bone information after adding the bone collision information, the binding information between the character body bones and the skin, the animation information of the character body bones, and the animation parameter configuration information, simulating the character simulation animation information and the wearable simulation animation information of the target animation character under the animation scene information.

[0065] Among them, the bone collision information may be the collision information between the character body bone information and the character wearable bone information. Specifically, the bone collision information can be introduced into the engine, and then the engine can calculate the character simulation animation information and the wearable simulation animation information of the target animation character under various animation scene information based on the character bone information after adding the bone collision information, the binding information between the character body bones and the skin, the animation information of the character body bones, and the animation parameter configuration information.

[0066] Through this optional implementation method, during the process of simulating the animation data of the target animation character under various animation scene information, the collision information between the character body bones and the character wearable bones can be introduced, avoiding the interpenetration of the character body and the wearable in the generated animation data, and further improving the display effect of the generated animation.

[0067] S230. Obtain the target resource information in the character simulation animation information and the wearable simulation animation information, and store the target resource information in the pre-constructed offline storage resource library.

[0068] Among them, the target resource information may include a speed change curve and pose information. Specifically, the speed change curve may be a curve describing the switching speed between each frame during frame switching; the pose information may be the pose conversion information between each frame during frame switching.

[0069] Specifically, after generating the character simulation animation information and the wearable simulation animation information, the target resource information in the character simulation animation and the target resource information in the wearable simulation animation information can be stored in the pre-constructed offline storage resource library.

[0070] In an alternative embodiment, if bone collision information is introduced during the generation of character simulation animation information and wearable simulation animation information, the bone collision information in the character simulation animation information and the wearable simulation animation information can be deleted, and the target resource information can be determined from the character simulation animation information and the wearable simulation animation information after deleting the bone collision information and stored in the offline storage resource library. That is, obtaining the target resource information in the character simulation animation information and the wearable simulation animation information and storing the target resource information in a pre-constructed offline storage resource library can be: discarding the bone collision information in the character simulation animation information and the wearable simulation animation information to obtain character storage animation information and wearable storage animation information; determining the target resource information in the character storage animation information and the wearable storage animation information, and storing the target resource information and the animation scene information in a corresponding manner in the pre-constructed offline storage resource library.

[0071] Among them, the target resource information includes the character speed change curve and the character pose information between each frame of animation corresponding to the character simulation animation information, and the wearable speed change curve and the wearable pose information between each frame of animation corresponding to the wearable storage animation information. Specifically, the character speed change curve can be a curve describing the change speed of the target animated character between every two consecutive frames of animation; the character pose information can be the pose conversion information of the target animated character between every two consecutive frames of animation. The wearable speed change curve can be a curve describing the change speed of the wearable between every two consecutive frames of animation; the wearable pose information can be the pose conversion information of the wearable between every two consecutive frames of animation. Exemplarily, the character pose information or the wearable pose information includes the rotation amount, the displacement amount, and the scaling amount.

[0072] In this alternative embodiment, considering that after generating the character simulation animation information and the wearable simulation animation information, the bone collision information is no longer needed, so the bone collision information can be discarded to store the character storage animation information and the wearable storage animation information after discarding the bone collision information in the offline storage resource library, reducing the amount of data in the offline storage resource library.

[0073] Specifically, the target resource information and the animation scene information corresponding to the target resource information can be associated and stored in the offline storage resource library. When real-time animation information needs to be generated, the corresponding target resource information can be queried from the offline storage resource library according to the animation scene information.

[0074] Exemplarily, storing the target resource information in a pre-constructed offline storage resource library includes: saving the target resource information as an offline resource file in a preset storage format, and storing the offline resource file in the pre-constructed offline storage resource library, where the preset storage format includes at least one of binary data format, texture data format, and custom data format.

[0075] Specifically, the target resource information can be saved as an offline resource file in binary data format, texture data format, or custom data format and stored in the offline storage resource library; or the target resource information can be saved as an offline resource file in at least two of binary data format, texture data format, and custom data format and stored in the offline storage resource library.

[0076] For example, considering that the target resource information includes character simulation animation information and wearable simulation animation information, the character simulation animation information and wearable simulation animation information in the target resource information can be stored separately. Exemplarily, an offline resource file in binary data format and an offline resource file in texture data format can be generated according to the target resource information, where the offline resource file in binary data format contains the character simulation animation information, and the offline resource file in texture data format contains the wearable simulation animation information.

[0077] Optionally, the binary data format, texture data format, and custom data format can be data formats that can be quickly read by the engine. The engine can obtain the pre-generated target resource information by reading the offline resource file, and then generate the next frame of animation information according to the target resource information.

[0078] S240. Obtain the character animation information of the current frame, where the character animation information includes target character information and current scene information.

[0079] S250. According to the target character information and the current scene information, obtain the target resource information corresponding to the character animation information from the pre-constructed offline storage resource library, where the target resource information includes character storage animation information and wearable storage animation information corresponding to the target character information and the current scene information.

[0080] S260. Generate the next frame of animation information according to the current scene information, character storage animation information, and wearable storage animation information.

[0081] The technical solution of this embodiment obtains the character bone information of the target animation character and the animation information of the character bone information, and simulates the character simulation animation information and the wearable simulation animation information of the target animation character under the animation scene information according to the animation parameter configuration information, the character bone information, and the animation information of the character bone information corresponding to the original animation information, realizing the pre-generation of the animation data of the target animation character under various animation scene information, providing offline resources for the real-time generation of the next frame of animation information of the current frame, and reducing the time cost and resource overhead required for real-time animation generation.

[0082] Embodiment III

[0083] Figure 3 FIG. is a schematic flowchart of an animation generation method provided by Embodiment III of the present invention. On the basis of the above embodiments, this embodiment exemplarily describes the process of obtaining the target resource information. As Figure 3 shown, the method includes:

[0084] S310. Obtain the character animation information of the current frame, where the character animation information includes the target character information and the current scene information.

[0085] S320. Determine the animation scene information that matches the current scene information, and obtain the target resource information corresponding to the target character information and the animation scene information from the pre-constructed offline storage resource library.

[0086] Among them, the animation scene information that matches the current scene information may be the animation scene information that is the same as the current scene information, or the animation scene information whose difference from the current scene information is less than the preset information difference threshold.

[0087] Specifically, considering that among the character simulation animation information and the wearable simulation animation information under each pre-generated animation scene information, there may not be animation scene information that is exactly the same as the current scene information. For example, the animation scene information in the pre-constructed offline storage resource library includes ground slopes of 0 degrees, 30 degrees, 60 degrees, and 90 degrees, and the ground slope in the current scene information is 25 degrees. Therefore, this embodiment can determine the animation scene information that matches the current scene information from each animation scene information.

[0088] Optionally, the scene information difference between the current scene information and each animation scene information can be calculated, and then the animation scene information matching the current scene information can be determined based on each scene information difference. For example, the animation scene information with the smallest scene information difference is determined as the animation scene information matching the current scene information. Among them, the characteristic information corresponding to the current scene information and each animation scene information can be determined first. For each animation scene information, the characteristic distance between the characteristic information of the current scene information and the characteristic information of the animation scene information is calculated, and the characteristic distance is used as the scene information difference.

[0089] For another example, the change curve of the scene information difference between the current scene information and each animation scene information can also be calculated, and the animation scene information matching the current scene information can be determined based on the change curve of the scene information difference. Specifically, the change curve of the scene information difference can describe the change trend of the scene information difference between the current scene information and each animation scene information. The animation scene information corresponding to the extreme value point or the maximum / minimum value point in the change curve of the scene information difference can be determined as the animation scene information matching the current scene information.

[0090] S330. Generate the animation information of the next frame according to the current scene information, the role stored animation information, and the wearable stored animation information.

[0091] In one implementation manner, considering that when the current scene information and the animation scene information are not completely consistent, if the target resource information corresponding to the animation scene information is directly used to generate the animation information of the next frame, the generated animation effect may not conform to the current scene. Therefore, in this embodiment, generating the animation information of the next frame according to the current scene information, the role stored animation information, and the wearable stored animation information includes: using a preset matching algorithm to convert the role stored animation information and the wearable stored animation information corresponding to the target role information under the animation scene information into the role target animation information and the wearable target animation information corresponding to the target role information under the current scene information; using the state machine overlay layer to generate the animation information of the next frame based on the current scene information and the role target animation information and the wearable target animation information corresponding to the target role information under the current scene information.

[0092] Among them, the preset matching algorithm can be a conversion algorithm for converting the target resource information under the animation scene information into the target animation information under the current scene information. Specifically, the preset matching algorithm can determine the animation information conversion amount based on the scene information difference between the animation scene information and the current scene information, and then convert the target resource information under the animation scene information into the target animation information under the current scene information based on the animation information conversion amount.

[0093] Furthermore, a state machine overlay can be adopted to generate the animation information of the next frame based on the character target animation information and the wearable target animation information under the transformed current scene information, as well as the current scene information.

[0094] Through this optional implementation, the target resource information under the animation scene information similar to the current scene information is transformed into the target animation information under the current scene information, making the generated animation information more in line with the current scene information, further improving the animation generation effect, and avoiding the situation where the animation effect does not conform to the current scene.

[0095] The technical solution of this embodiment realizes the accurate acquisition of the target resource information by determining the animation scene information matching the current scene information and obtaining the target resource information corresponding to the target character information and the animation scene information from the pre-constructed offline storage resource library, avoiding the situation where the target resource information cannot be obtained when there is no animation scene information consistent with the current scene information in the offline storage resource library. Moreover, it can also make it unnecessary to enumerate the target resource information under all animation scene information during the process of constructing the target resource information in the offline storage resource library, and only construct the target resource information under part of the animation scene information, reducing the data volume in the offline storage resource library and improving the construction efficiency of the offline storage resource library.

[0096] Embodiment 4

[0097] Figure 4 It is a schematic structural diagram of an animation generation device provided by Embodiment 4 of the present invention. As Figure 4 shown, the device includes a character acquisition module 410, a resource acquisition module 420, and an animation generation module 430.

[0098] The character acquisition module 410 is used to acquire the character animation information of the current frame, where the animation information includes target character information and current scene information;
