Description

Animation processing method and device, electronic equipment and storage medium

Technical Field

The present application relates to the field of animation processing technologies, and in particular, to an animation processing method and apparatus, an electronic device, and a storage medium.

Background

When the animation is previewed in a skeletal animation editing tool (such as Spine), the animation is previewed based on the default state of a skeletal model, and when the animation runs in a game engine, only the first frame of animation is played from the default state, and the subsequent frames of animation are played next to the previous frame of animation and are not played from the default state.

When animation is transited, that is, when switching from one animation to another animation, if a node exists in the animation, the node is related to a key frame in the previous animation, and there is no key frame in the next animation, after the animation is switched, because the state of the node in the next animation is inconsistent with the default state and the key frame is lacked to forcibly update the state of the node, the state of the node in the previous animation remains on the next animation, and an abnormality occurs when the animation is presented, which seriously affects the game quality.

For the residual problem during animation transition, it is only required to forcibly update the abnormal node on the subsequent animation, and the current method generally includes: finding abnormal nodes in a manual mode, and adding key frames in the animation by using the default states of the abnormal nodes. However, when the number of animations is large, the processing efficiency of the abnormal node by the manual method is low.

In addition, the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

The animation processing method of the embodiment of the application can be applied to terminal equipment and can also be applied to any other computing equipment with a processing function. In some embodiments, the terminal device or computing device may include a processor. The processor may process the information and/or data related to the request to perform one or more of the functions described herein.

In the related art, a Cocos game engine is widely applied to game production as a cross-platform game engine, but the Cocos engine supports two-dimensional animation production, but the produced animation has limited functions and cannot meet the complex requirements of players, and when the Cocos game engine is used for producing a game, if animation with stronger expressive force is needed, a professional animation production tool is often needed to be matched for use. Thus, it is contemplated that animation tools, such as the Spine tool, may be used to animate in conjunction with the Cocos game engine.

The Spine tool is an animation tool supporting most game engines, and supports advanced animation functions such as animation transition, animation fusion, skin replacement, flexible animation, drawing sequence adjustment and the like. In applying the Spine tool to the Cocos game engine, the animation process generally comprises: first, the skeleton and the map are assembled in the Spine tool, resulting in the default pose of the animation, i.e., the initial state of the animation (also called the SetupPose state), then, key frames are added to the animation based on the SetupPose state, the key frame is generally a frame where a key action in the movement or change of the character or object is located, and the purpose of the key frame is to make the animation switching smoother, the key frame generally contains the setup _ Pose state information of the node that needs to be operated by animation switching (motion transition), the node is generally a part (such as an arm, a leg, an eye, a foot, etc.) in the model, the model can be a skeleton model of any object (such as human body, animal, etc.), animation can be previewed in a Spine tool directly after the key frame is made, and manually exporting the animation through a Spine tool, and adding the exported animation file into the game directory. When the animation is played in the game, the animation is played according to the key frame.

Before the animation is derived by the Spine tool, the animation is previewed by the Spine tool, when the animation is previewed by the Spine tool, the SetupPose state of the node is used as an initial state for previewing, when the Cocos game engine actually runs, only the first action in the animation is played from the SetupPose state, the animation corresponding to the subsequent action is played from the previous action, and the animation corresponding to the subsequent action is not played from the initial state. Therefore, when the animation corresponding to the action is transited, if a node exists, the node is related to a key frame in the previous animation, but does not have a key frame in the next animation, after the animation is transited, the current state of the node is inconsistent with the initial state of the node, and the node is forcibly updated due to the lack of the key frame, finally, the running state of the node in the previous animation is remained on the next animation, and the animation is abnormally represented, thereby seriously affecting the game quality.

Aiming at the problem of residue in animation transition, only a residual node needs to be forcibly updated on the next animation, and the current general method is as follows: the animation frames in the animation are modified manually, i.e., an abnormal node in the animation is found, a key frame is added to the subsequent animation by using the SetupPose state of the abnormal node, and the animation is exported again. Therefore, when animation transition occurs, the subsequent animation forcibly updates the state of the animation node to the default state through the key frame, and the residual problem can be corrected.

However, the residuals are corrected manually, and when the number of animation frames is large, even an undiscovered residual problem may exist, which increases the processing difficulty and reduces the processing efficiency. In addition, when a new animation containing new nodes is created at the development end, almost all previous animations need to be subjected to frame supplementing, and the workload is increased.

In addition, when the animation is exported by the Spine tool, the animation is generally exported manually, export parameters are manually estimated, and the parameters are not standardized, so that export files are not good, for example, if the texture of the animation is large, the side effects of wasting disk space, increasing a game bag body, wasting precision, slowing game running and the like can be generated; if the texture of the animation is too small, the picture will not perform well, and the quality of the game will be affected. When the Spine tool is used for exporting the animation, the exported effect cannot be directly previewed, the animation needs to be previewed in the game, export parameters need to be corrected for multiple times, and then a proper export texture can be obtained, so that the animation can finally meet the game requirement through a series of feedback processes and multiple times of modification of the export parameters, and development efficiency is low.

Based on this, the embodiment of the application provides an animation processing method, so as to improve the processing efficiency of the animation and improve the quality of the animation played by a game. Specifically, the present application obtains node identifiers of operation nodes corresponding to at least one action sequence included in an animation file, and node default state information corresponding to each operation node, wherein each action sequence includes at least one execution action, determines, for each action sequence, at least one difference node of the action sequence compared with other action sequences based on the node identifier of the operation node corresponding to the action sequence and the node identifiers of the operation nodes corresponding to other action sequences, the difference node being an operation node corresponding to an execution action not included in the action sequence, and complements a frame for the animation file based on the node default state information corresponding to the determined operation node, so as to obtain an animation file after complementing the frame, thereby improving processing efficiency of the animation, when the animation file is applied to a game, the animation corresponding to each action sequence is presented from the default state of the node in the presentation process, so that smooth transition of the action sequence can be realized when the action sequence is switched, and the picture quality of the game is improved.

The idea of an embodiment of the present application is described in detail below.

The embodiment of the application provides an animation processing method, as shown in fig. 1, specifically including the following steps:

s101, acquiring node identifiers of operation nodes respectively corresponding to at least one action sequence in an animation file, and node default state information corresponding to each operation node; each action sequence comprises at least one execution action;

s102, aiming at each action sequence, determining at least one difference node of the action sequence compared with other action sequences based on the node identification of the operation node corresponding to the action sequence and the node identifications of the operation nodes corresponding to other action sequences respectively, wherein the difference node is the operation node corresponding to the execution action not included in the action sequence;

and S103, performing frame supplementing processing on the action sequence according to the node default state information corresponding to the different node.

In S101, the animation file is typically an animation project exported using Spine tools, the animation project is generally an animation for a game character, which may be a character, an animal, a hero, etc., and the animation file generally includes at least one sequence of actions, the action sequence may be each action sequence that a game character may execute during game running, where each action sequence includes at least one execution action, and executing one execution action may require cooperation of multiple nodes in the game character, where the node may be a skeleton (e.g., a bone), an Inverse Kinematics (IK) node (e.g., a special part of a model), a slot (e.g., a container displaying a picture in a skeleton animation), and so on, and a node when each execution action is executed is used as an operation node, that is, an operation node corresponding to each action sequence is a node used by an action executed during animation playing. The execution action can be running, jumping, dancing, shooting, blinking eyes and other actions, and the node identification can be identified through numbers, letters, characters and the like.

The node default state information is the setupose state information of the node, and the node default state information comprises a position coefficient, a rotation coefficient, a scaling coefficient, a shearing coefficient and the like of the node, and can be determined according to actual conditions.

The node identifier of the operation node and the node default state information are obtained by analyzing an animation intermediate file, wherein the animation intermediate file can be obtained by exporting an animation source project, and the animation source project comprises an animation file and a texture file.

When the animation source engineering is exported, the animation source engineering is generally exported twice. The first export of the generated animation intermediate file is mainly used to correct the defects in the animation and obtain the optimal texture file adjustment coefficients (described in detail below). The second derivation takes the corrected animation intermediate file as input, the obtained texture file adjusting coefficient is used for deriving the texture file, and the finally obtained animation running file effectively reduces the size of derived animation resources while ensuring the animation quality.

Defects in the animation are corrected through the animation intermediate file exported for the first time, the animation is subjected to frame supplementing processing automatically, the performance of the animation is not required to be checked through running a game, secondary modification is not required to be carried out on an animation source project, a plurality of problems generated during animation transition in the game can be solved, and the animation making time is shortened.

In the specific implementation process, the animation source project needing export processing may not be a single animation project but may be a plurality of animation projects, and different animation projects are only required to be distinguished according to folders during export, so that batch export is realized, and export time is greatly reduced. In order to ensure that the animation source project needing to be exported is the latest animation source project, before the export, an updated animation file is obtained, and the updated animation file can be obtained by updating the animation project by using an updating tool such as a version control System (SVN), a distributed version control system (Git), or a mirror image backup tool (rsync).

Considering that a development end modifies an animation source project, for example, adding an action in the animation source project, the modification may occur before the animation source project is exported or after the animation source project is exported, and when the animation source project is modified, the modification time of the animation source project is the latest time, in order to improve the export speed, before the animation source project of an animation file is exported by using an animation converter, judging whether the latest time of the animation source project is later than the export time of the animation source project recorded by a system, if so, indicating that the animation source project is modified after the last export, and needing to perform frame supplementing processing on the animation source project again, that is, needing to analyze an intermediate file of the exported animation so as to perform subsequent frame supplementing processing; otherwise, the animation source project of the animation file is subjected to frame supplementing processing, and the next animation is processed, so that repeated processing of the animation source project subjected to export processing is avoided, and the processing efficiency is improved.

When the animation source project of the animation file is exported (exported for the first time), a uniform export parameter (the export parameter can be determined according to a historical export parameter) is generally used, the export process is aimed at performing frame supplementing processing on an action sequence in the animation file, and when the frame supplementing processing is performed, a texture file and unnecessary operation data (animation production data) are not necessary data, so that the texture file can not be exported when the animation source project is exported for the first time, an animation intermediate file with unnecessary operation data removed is obtained, and the animation intermediate file in a text format is exported for facilitating the operation of an originating terminal, namely, the animation intermediate file with the animation production data removed and in a text format is exported from the animation file to obtain a visual animation intermediate file, so that the export data is reduced, and the export speed is accelerated. The animation production data is data generated in the process that a research and development end uses a Spine tool to produce an animation file, and the data can be skeleton color data in a texture file, a source texture file path, shooting list frame rate data used for previewing the animation in Spine, an audio path and the like.

After the animation intermediate file is obtained, the animation intermediate file needs to be analyzed twice, so that the node identification and the node default state information of the operation node are obtained. When the animation intermediate file is analyzed for the first time, node default state information of the operation nodes corresponding to each action sequence included in the animation file is obtained, and the node default state information of the operation nodes can be stored in a list form. Then, the animation intermediate file is analyzed again, the node identifier of the operation node corresponding to each action sequence included in the animation file and the node state information of each operation node are obtained, the node state information is the state information of the node in different frames, and generally includes the position of the node in the current frame, the offset of the node in the current frame and the like, the node identifier of the operation node corresponding to each action sequence and the node state information of the operation node are stored in the form of an animation frame list, that is, one action sequence corresponds to one animation frame list, and one item in the animation frame list is one animation frame. The node default state information and the node state information corresponding to each action sequence can be obtained by analyzing the animation intermediate file once or obtained in different times.

When the animation file is applied to a game, corresponding action sequences are triggered in response to touch operations of a player, the game presents an animation effect corresponding to the action sequences, considering that the touch operations of the player are performed based on a game scene, and there may not be a correlation between action sequences triggered by different touch operations, that is, there may not be an inevitable execution sequence for the execution of the action sequences, and there may also be an execution sequence between some action sequences, for example, the animation file includes an action sequence A, B, C, after the action sequence a is triggered by the player, an action sequence B may be triggered, and after the action sequence B is triggered, an action sequence a may be retriggered, and at this time, there is no execution sequence between the action sequences A, B, C; or, after triggering the action sequence a, the player necessarily triggers the action sequence B, and at this time, there is a sequential execution order between the animation sequences a and B.

The following is introduced for the case where the sequence of actions has and does not have an execution order:

the first condition is as follows: and in the running process of the game, the action sequence corresponding to the presented animation does not have a sequential execution sequence.

Determining at least one difference node of the action sequence compared with other action sequences based on the node identifier of the operation node corresponding to the action sequence and the node identifiers of the operation nodes corresponding to other action sequences respectively, specifically comprising:

Here, the first performing action may comprise at least one performing action, the performing action being referred to above.

In a specific implementation process, regarding each action sequence in the animation file, taking each action sequence except the action sequence as a current comparison sequence, and comparing the node identifier of the operation node corresponding to the action sequence with the node identifier of the operation node corresponding to the current comparison sequence.

If the operation node corresponding to the action sequence does not include an operation node corresponding to a first execution action in the current comparison sequence, that is, the operation node corresponding to the action sequence is different from the operation node corresponding to the execution action included in the current comparison sequence, and the different operation nodes are the operation nodes corresponding to the first execution action in the current comparison sequence, the operation node corresponding to the first execution action is taken as the operation node corresponding to the action sequence compared with the current comparison sequence, and the operation nodes corresponding to the execution actions not included are sequentially compared with other action sequences taken as the current comparison sequence, so that the operation node corresponding to the action sequence compared with other action sequences and the operation node corresponding to the execution action not included is obtained.

If the operation node corresponding to the action sequence comprises an operation node corresponding to an execution action in the current comparison sequence, that is, the operation node corresponding to the action sequence is the same as the operation node corresponding to the current comparison sequence, a action sequence is obtained again from other action sequences, the obtained action sequence is used as the current comparison sequence, the step of comparing the node identification of the operation node corresponding to the action sequence with the node identification of the operation node corresponding to the current comparison sequence is continuously carried out until all other action sequences are compared, and finally at least one difference node of the action sequence compared with other action sequences is obtained.

For example, A, B, C is included in the animation file, action sequence a includes three operation nodes, which are a1, a2 and A3, action sequence B includes three operation nodes, which are B1, a2 and B3, action sequence C includes three operation nodes, which are a1, C2 and C3, action sequence a is taken as an action sequence that requires to determine an operation node corresponding to an uncontained execution action, B and C are respectively taken as current alignment sequences, the operation node corresponding to action sequence a and the operation node corresponding to action sequence B are aligned, it is found that operation node B1 and B3 in action sequence B are not included in action sequence a, operation node B1 and B3 are determined to be action sequence a and operation node corresponding to an uncontained execution action, and similarly, operation node C2 and C3 are determined to be action sequence a and action sequence C, the operation nodes corresponding to the execution actions not included may finally be determined as B1, B3, C2 and C3 when the action sequence A is compared with the action sequences B and C.

Case two: during game operation, the action sequence corresponding to the presented animation has an execution sequence.

When determining at least one difference node of the action sequence compared with other action sequences based on the node identifier of the operation node corresponding to the action sequence and the node identifiers of the operation nodes corresponding to other action sequences, the method specifically includes the following steps:

and determining that the operation node corresponding to the action sequence does not contain an operation node corresponding to a second execution action in the action sequence adjacent to the execution sequence of the action sequence based on the node identifier, and taking the operation node corresponding to the second execution action as the at least one difference node.

Here, the execution sequence is generally a sequential execution sequence between two or more action sequences, that is, when the animation corresponding to the action sequence is presented, the animation corresponding to the action sequence before the execution sequence is preferentially displayed, and then the animation corresponding to the action sequence after the execution sequence is displayed; the second performed action includes at least one performed action.

In a specific implementation process, aiming at each action sequence in the animation file, the node identification of the operation node corresponding to the action sequence is compared with the node identification of the operation node corresponding to the action sequence adjacent to the action execution sequence.

If the operation node corresponding to the action sequence does not include an operation node corresponding to a second execution action in an action sequence adjacent to the execution sequence in the execution sequence, that is, the operation node corresponding to the action sequence is different from the operation node corresponding to the execution action included in the action sequence adjacent to the execution sequence in the execution sequence, and the different operation node is the operation node corresponding to the second execution action in the previous action sequence, the operation node corresponding to the second execution action is taken as the operation node corresponding to the execution action not included in the action sequence compared with other action sequences.

If the operation node corresponding to the action sequence comprises an operation node corresponding to a second execution action in an action sequence adjacent to the execution sequence of the action sequence, namely, the operation node corresponding to the action sequence is the same as the operation node corresponding to an action sequence adjacent to the execution sequence, selecting an action sequence from other action sequences corresponding to the animation file except the action sequence, judging whether the action sequence corresponds to a preset execution sequence, if the selected action sequence is preset with the execution sequence, executing a step of comparing the node identification of the operation node corresponding to the action sequence with the node identification of the operation node corresponding to the action sequence adjacent to the action execution sequence, and if the selected action sequence does not preset the execution sequence, comparing the node identification of the operation node corresponding to the action sequence with the node identification of the operation node corresponding to the current comparison sequence in the first execution case And (5) identifying.

Continuing with the above example, if there is an execution order between the action sequence a and the action sequence B, and the execution order of the action sequence a is prior to the action sequence B, when determining an operation node corresponding to an execution action not included in the action sequence B, the operation node corresponding to the action sequence a is compared with the operation node corresponding to the action sequence B, and it is found that the operation nodes a1 and A3 in the action sequence a are not included in the action sequence B, it is determined that the operation nodes a1 and A3 are operation nodes corresponding to execution actions not included in the action sequence B as compared with the action sequence a.

After determining an operation node corresponding to an execution action which is not included in each action sequence, performing frame interpolation processing on each action sequence, wherein each animation frame corresponding to the action sequence is stored in an animation frame list form, and each item in the list corresponds to one animation frame, so that when performing frame interpolation processing on the action sequence according to the node default state information corresponding to the different node, frame interpolation processing can be performed before a first animation frame corresponding to the action sequence according to the node default state information corresponding to the different node, and the method specifically comprises the following steps:

Here, the animation frame includes node default state information of each operation node determined for the action sequence.

In a specific implementation process, for each action sequence, generating an animation frame for the action sequence by using the node default state information of the operation node determined for the action sequence, where the animation frame includes the node default state information of the operation node determined for the action sequence, and adding an entry to the first entry in the animation frame list corresponding to the action sequence, and writing the generated animation frame into the added entry in the animation frame list, that is, writing the node default state information of the operation node determined for the action sequence into the added entry, thereby completing the frame supplement for the action sequence.

After completing the frame supplementing of each action sequence of the current action, the defect correction of the animation is realized, and further the node default state information of each operation node obtained by analysis and the animation frame list after the frame supplementing corresponding to each action sequence can be rewritten into the animation intermediate file.

When exporting the animation file after frame supplementing, the animation file after frame supplementing can be taken as a source through a Spine command line, the export parameters after correction are used, the export parameters comprise texture file adjusting coefficients (detailed below) and file format export settings, and then the animation file in the binary format and the texture file after adjustment can be exported, namely, the texture file corresponding to the animation file is exported, and the animation file in the binary format is exported based on the animation file in the text format after frame supplementing; obtaining an animation running file based on the exported texture file and the animation file in the binary format; the animation running file is used for controlling the playing of the animation in the game. Therefore, the exported animation file not only contains the original animation frames of the animation file, but also contains the added animation frames, so that the animation defects are corrected, and a texture file with a proper size is obtained by using a proper texture file adjusting coefficient.

Considering that the export result (animation running file) exported again from the modified animation intermediate file is directly applied to the game, after the frame supplementing processing is carried out on the animation file, the texture scaling coefficient corresponding to the texture file is adjusted so as to obtain a proper texture file when the texture file is exported again, therefore, the running quality of the game can be improved, and the animation file in the binary format is exported when the animation file after the frame supplementing processing is exported, but the animation file in the binary format is smaller, and when the animation file is run in the game, the animation file does not need to be compiled, so that the running speed of the game is improved.

The following describes a process for determining an adjustment coefficient of a texture file, specifically:

determining a root operation node from the plurality of operation nodes based on node default state information corresponding to the different nodes;

extracting a texture scaling coefficient corresponding to the root operation node from the initial state information corresponding to the root operation node;

Here, the node default state information includes a root operation node and a child operation node, the root operation node may be identified by a node identifier, such as root, and the node default state information includes a texture scaling factor corresponding to the root operation node.

In a specific implementation process, a root operation node is determined based on a node identifier of an operation node included in node default state information, further, a texture scaling coefficient of the root operation node is extracted from the node default state information corresponding to the root node, if the texture scaling coefficient is greater than or equal to a first preset value, a texture file adjustment coefficient of an animation file is set to be a second preset value, and if the texture scaling coefficient is less than the first preset value, a sum of the texture scaling coefficient and a third preset value is used as the texture file adjustment coefficient of the animation file. The first preset value is generally 0.9, the second preset value is generally 1, and the third preset value is generally 0.1.

The texture file adjustment coefficient may be determined according to the following formula:

wherein s is a texture file adjustment coefficient, rs is a texture scaling coefficient of the root node, α is a third preset value which can be 0.1, β is a first preset value which can be 0.9, and γ is a second preset value which can be 1.
