Computing device 100 may also be a mobile or stationary server.

Wherein the processor 120 may perform the steps of the animation generation method shown in fig. 2. Fig. 2 shows a flowchart of an animation generation method according to an embodiment of the present application, which specifically includes the following steps:

Step 202, determining an animation object based on the received animation creation instruction.

The animation creation instruction is an instruction for creating a playable animation file, and the animation object can be understood as animation resources such as animation characters, cameras, animation props and the like. In practical applications, when the animation editor receives the animation creation instruction, it is necessary to determine animation data for creating an animation file, and then create the animation file based on the animation data. The animation editor may be an animation editor for executing an animation, or may be a plug-in editor in an animation editor as another animation, which is not limited herein.

In particular, in order to optimize the process of creating the animation by the user and facilitate the user to manage the animation elements (including the animation objects) in the animation, the animation objects may be created first, and then other animation elements that affect the animation objects may be created based on the created animation objects, so as to perform classification management on various animation elements based on the animation objects.

Therefore, how to create the animation object has great influence on the animation creation process, if the created animation object can well classify the animation elements and meet the creation requirement, the efficiency of creating the animation by a user can be greatly improved, and when the method is implemented, some animation resources mainly or frequently used in the animation creation process can be firstly classified according to functions or categories, and then the animation object is created based on the classified animation object types.

In practical application, after the user submits the object creation instruction, the user is presented with the types of animation objects that can be created, and these types of animation objects are presented in the form of an animation object list, and specifically, the animation object type list includes animation object types such as director type, camera type, actor type, special effect type, and lamplight type. Further, the director type animation object is used for controlling the whole animation, such as controlling shot switching, animation playing speed and the like in the animation, the camera type animation object determines an observation view angle and a display range of the played animation, the actor type animation object refers to a virtual object in the animation, the special effect type animation object determines a special effect in the animation, the light type animation object determines a light effect in the animation, and in addition, the animation object type list can also comprise a scene type animation object type and the like used for setting a scene, which is not limited herein.

Based on this, the user can select the animation object type that he wants to create (i.e., the target animation object type) in the list of animation object types, and then can create an animation object based on the target animation object type.

In the implementation, the main animation object types are abstracted in an animation editor, and the animation objects required by the requirements of the animation scene can be created according to the animation object types in the animation editing process.

For example, an object creation instruction submitted by a user U in an animation editor is received, an animation object type list preset in the animation editor is displayed in response to the object creation instruction, the animation object type list comprises a director type, a camera type, an actor type, a special effect type and a lamplight type, an actor type selected by the user U in the animation object type list is received as a target animation object type, and an animation object of the actor type, actor 1, is created.

In summary, in response to the received object creation instruction, the animation object type list is displayed, and the animation object corresponding to the target animation object type is created based on the target animation object type selected in the animation object type list, so that the creation of the corresponding animation object based on the pre-divided animation object types is realized, the type division of the animation object is realized, the creation of the animation object by flexibly selecting the required creation animation object type from a plurality of animation object types is realized, and the flexibility of creating the animation object is increased.

And 204, reading an animation event which is created in advance for the animation track corresponding to the animation object. Specifically, on the basis of the above determination of the animation objects, since the animation editor performs hierarchical management on other animation elements on the basis of the animation objects in order to avoid the influence of the animation objects on each other during the animation editing and to increase the difficulty of the animation creation due to improper management of the animation elements, when creating the animation file, the animation editor may read the corresponding animation elements according to the hierarchical relations and then create the animation file.

Wherein the animation track is a time axis set by the pointer to the animation object, and the animation track can be used for managing the animation event of the animation object. Wherein, the animation event refers to a preconfigured set of animation functions for enabling an animation object to execute a specific animation function at a specific moment.

In the embodiment of the application, the method is realized by reading a basic animation event which is pre-created for an active picture track corresponding to the animation object and reading an extended animation event which is pre-created for a sub-animation track associated with a target animation object, wherein the target animation object is an animation object of the associated sub-animation track in the animation object, and particularly, dividing the animation track into two track types of an active picture track and a sub-animation track, and dividing the animation event into two event type sets of a basic animation event and an extended animation event, wherein any basic animation sub-event in the basic animation event is an animation sub-event, and any extended animation sub-event in the extended animation event is also an animation sub-event.

In practical application, each animation object corresponds to a main animation track, and a plurality of basic animation sub-events can be created or configured on the main animation track, and the basic animation sub-events form a basic animation event. In addition, when the base animation event fails to meet the configuration requirements for the animation object, at least one associated sub-animation track may also be created or added for the animation object such that a corresponding at least one extended animation sub-event is created or configured on each sub-animation track, the sub-extended animation sub-events comprising the extended animation event.

The active drawing track is a basic time axis which is set by a pointer to an animation object and used for carrying out basic animation event management, and is used for carrying out time management on basic animation events of the animation object during the animation playing. Accordingly, the base animation sub-events in the base animation event are used to cause the animation object to perform base animation functions such as binding objects, binding actors, following, etc. The sub-animation track is an extended time axis for extended animation event management, which is set for the animation object by the pointer, and is used for time management of the extended animation event of the animation object during the animation playing. The number of the sub-animation tracks may be one or more, and is not limited herein. Accordingly, the extended animation sub-event in the extended animation event is used to cause the animation object to perform an extended animation function such as an action, a skeletal action, a facial animation, etc. In practical application, which animation sub-events belong to basic animation sub-events and which animation sub-events belong to extension sub-events are set in an animation editor in advance according to the types of the animation sub-events.

In the implementation, considering that the types of the extended animation sub-events are also various, in order to avoid that the extended animation sub-events of various types are managed on one sub-animation track, so as to influence the editing efficiency of the animation, the sub-animation track types can be set in advance according to the types of the extended animation sub-events corresponding to each animation object type, and then the sub-animation track is created according to the sub-animation track types.

The sub-track creation instruction is an instruction for creating a sub-animation track. In practical applications, since the sub-animation track exists depending on the animation object, it is used to manage the extended animation event of the animation object. Thus, sub-track creation instructions may be submitted for an animation object that configures an extended animation sub-event. The purpose of creating the sub-animation track is to create the extended animation sub-event thereon and manage the extended animation sub-event through the sub-animation track.

Further, since each type of animation object may correspond to multiple types of animation implementations, these different types of animation implementations are typically related to object properties (e.g., functions, object locations, etc.) of the animation object. Accordingly, a plurality of sub-animation track types may be previously divided according to object attributes of each animation object, and the sub-animation track types may be formed into a sub-animation track list. So that the corresponding type of extended animation event is managed on different types of sub-animation tracks. When creating the sub-animation track for any one animation object, the sub-animation track list associated with the object attribute of any one animation object can be displayed. And creating a sub-animation track corresponding to the target sub-track type based on the target sub-track type selected by the user in the sub-track type list, and taking the created sub-animation track as the sub-animation track associated with any one of the animation objects.

On the basis of the creation of the animation object, namely, the actor 1, the method receives a sub-track creation instruction submitted by a user U in an animation editor aiming at the actor 1, and responds to the sub-track creation instruction to display a sub-animation track type list which is preset in the animation editor and is associated with functions and parts of the actor 1, wherein the sub-animation track type list comprises action types, facial action types and the like. And receiving the action type selected by the user U in the sub-animation track type list as a target sub-animation track type, creating a sub-animation track of the action type, namely, an action track, and taking the created action track as a sub-animation track associated with the animation object actors.

In summary, a sub-animation track is created based on a target sub-track type selected in a sub-track type list by receiving a sub-track creation instruction for any one of a plurality of animation objects and exposing a sub-track type list associated with an object attribute of the any one of the animation objects in response to the sub-track creation instruction. The method realizes the type division of the sub-animation track, flexibly selects the required sub-animation track type from a plurality of sub-animation track types to create the sub-animation track, and increases the flexibility of creating the sub-animation track.

In practical application, since some animation objects may have associated sub-animation tracks, and some animation objects do not have associated sub-animation tracks created, in order to read an extended animation event created in advance on the sub-animation tracks, it is necessary to determine the animation object associated with the sub-animation track (i.e., a target animation object) first.

In the implementation, on the basis of creating the animation objects, since different basic functions can be implemented for each animation object, in order to avoid the mutual influence between different basic functions, different basic functions of the animation objects can be divided into different basic sub-event types in advance, and then the basic animation sub-events are created according to the basic sub-event types.

The basic sub-event adding instruction refers to an instruction for adding a basic animation sub-event. In practical application, since any one basic animation sub-event has a time interval for event execution, the time interval is composed of an event start time and an event end time. The time interval may be embodied on an animation timeline. And the basic animation sub-event is used for realizing the basic function of the animation object, so that the basic animation sub-event is created on a basic time axis (active picture track) corresponding to the animation object. Also, therefore, when creating a base animation sub-event, a base sub-event creation instruction needs to be submitted for a base time axis (active drawing track).

Further, since the event types of the base animation sub-events corresponding to each animation object are various, different types of base animation sub-events may require different properties to be set. To avoid interaction between different types of base animation sub-events, it is necessary to divide the base animation sub-events into at least one base sub-event type according to the animation objects and form the base sub-event types into a base sub-event type list. And when the basic animation sub-event is created on the active picture track corresponding to any one animation object, the basic sub-event type list corresponding to the active picture track corresponding to the animation object can be displayed. And creating a basic animation sub-event corresponding to the target basic sub-event type based on the target basic sub-event type selected by the user in the basic sub-event type list. It should be noted that at least one base animation sub-event may be created for the main animation track, and the set of base animation sub-events is referred to as a base animation event.

On the basis of creating the animation object, namely, the actor 1, a basic sub-event creation instruction submitted by a user U in an animation editor aiming at an active drawing track corresponding to the actor 1 is received, a basic sub-event type list corresponding to the active drawing track of the actor 1 is preset in the animation editor in response to the basic sub-event creation instruction, and the basic sub-event type list comprises a binding object type, a binding actor type and a following type. And receiving a binding object type selected by the user U in the basic sub-event type list as a target basic sub-event type, and creating a basic animation sub-event of the binding object type, wherein the binding object A specifically shows that the binding object A is displayed in a scene in a time interval corresponding to the event.

In summary, a basic sub-event creation instruction for an active drawing track corresponding to any one of a plurality of animation objects is received by aiming at any one of the animation objects, and in response to the basic sub-event creation instruction, the corresponding basic animation sub-event is created by a target basic sub-event type selected in a basic sub-event type list. The method and the device realize the type division of the basic animation sub-event of the animation object, flexibly select the needed basic sub-event type from a plurality of basic sub-event types to create the basic animation sub-event, and increase the flexibility of creating the basic animation sub-event.

Similarly, on the basis of creating the animation objects, since different expansion functions can be implemented for each animation object, in order to avoid the mutual influence between different expansion functions, different expansion functions of the animation objects can be divided into different expansion sub-event types in advance, and then the expansion animation sub-events are created according to the expansion sub-event types.

The extended sub-event creation instruction refers to an instruction for adding an extended animation sub-event. In practical application, since any one of the extended animation sub-events has a time interval for event execution, the time interval is also composed of an event start time and an event end time. The time interval also needs to be represented on the animation time axis. And the extended animation sub-event is to implement an extended function of the animation object, so the extended animation sub-event is created on an extended time axis (i.e., sub-animation track) associated with the animation object. Also, therefore, when creating an extended animation sub-event, it is necessary to submit an extended sub-event creation instruction for a sub-animation track.

Further, since event types of the extended animation sub-event are diverse, different types of extended animation sub-events may require setting different attributes. To avoid interaction between different types of extended animation sub-events, it is necessary to divide the extended animation sub-events into at least one extended sub-event type according to the animation object and form the extended sub-event types into an extended sub-event type list. And when the extended animation sub-event is created on the sub-animation track associated with any one animation object, the extended sub-event type list corresponding to the sub-animation track associated with the animation object can be displayed. And creating an extended animation sub-event corresponding to the target extended sub-event type based on the target extended sub-event type selected by the user in the extended sub-event type list. It should be noted that at least one extended animation sub-event may also be created for the sub-animation track, and the set of extended animation sub-events is referred to as an extended animation event.

On the basis of creating the animation object, namely, the actor 1, an expansion sub-event creation instruction submitted by a user U aiming at an action track associated with the actor 1 in an animation editor is received, and an expansion sub-event type list corresponding to the action track of the actor 1 is preset in the animation editor in response to the expansion sub-event creation instruction, wherein the expansion sub-event type list comprises a leg action type, a hand action type and a head action type. And receiving the leg action type selected by the user U in the extended sub-event type list as a target extended sub-event type, and creating an extended animation sub-event of the leg action type, namely a kicking sub-event. The kicking event means that the actor 1 is controlled to perform a kicking operation in a time zone corresponding to the event.

In particular, as shown in fig. 3, an animation object, actor 1, has been created in the animation editor, and the animated character of actor 1 is shown in the animation display region of the animation editor. In addition, actor 1 has a corresponding active picture track and a sub-animation track, and a base animation sub-event, binding object A, is created for the corresponding active picture track of actor 1, and an extended animation sub-event, kicking sub-event, is created for the sub-animation track associated with actor 1.

In summary, by aiming at any one of a plurality of target animation objects, an expansion sub-event creation instruction of a sub-animation track associated with the any one target animation object is received, and in response to the expansion sub-event creation instruction, a corresponding expansion animation sub-event is created by a target expansion sub-event type selected in the expansion sub-event type list. The method realizes the type division of the extension animation sub-event of the animation object, flexibly selects the required extension sub-event type from a plurality of extension sub-event types to create the extension animation sub-event, and increases the flexibility of creating the extension animation sub-event.

In practice, it may be desirable to view the created animation sub-event (base animation sub-event or extended animation sub-event). When editing the animation sub-events in the animation editor, if the event operation sub-region of each animation sub-event is traversed linearly, so as to determine the animation sub-event matched with the user click, the time consumption is long. Thus, the event operation sub-area of each animation sub-event can be traversed in the form of a quadtree, and the embodiment of the application further comprises:

The event operation area refers to an interface area which is included in the animation editor and can operate at least one animation sub-event. The event inquiry instruction refers to an instruction for inquiring any one of the animation sub-events (basic animation sub-event or extended animation sub-event), each event operation sub-region refers to any one of the created animation sub-events, and the event operation sub-region corresponds to an operation sub-region of the event operation region, and can be understood as an event bounding box.

In practical application, in order to query an already created animation sub-event, the already created animation sub-event is generally mapped in an editing interface of an animation editor in a manner of an event operation sub-region, so that a user views any one animation sub-event when submitting an event query instruction by operating in the event operation sub-region corresponding to the any one animation sub-event. But because the animation sub-event which the user wants to view is determined according to the user operation position. Therefore, the position information carried in the event query instruction of the user needs to be compared with the event operation sub-area of the animation sub-event contained in the event operation area to determine the event operation sub-area matched with the position information. And taking the animation sub-event corresponding to the matched event operation sub-region as the animation sub-event corresponding to the event inquiry instruction.

In the implementation, the event operation sub-area corresponding to the position information can be determined by traversing an event quadtree formed based on the event operation sub-area corresponding to the created animation sub-event, that is, by traversing the event quadtree corresponding to the event operation area, comparing the position information carried in the event query instruction (for example, the click position information carried in the click submitted event query instruction) with the event operation sub-area corresponding to each leaf node in the event quadtree. And taking the animation sub-event corresponding to the corresponding event operation sub-region as a target animation sub-event, and displaying the target animation sub-event (a target basic animation sub-event or a target extension animation sub-event). Specifically, the target animation sub-event can be displayed through an event panel for displaying the target animation sub-event.

Further, the user can edit the queried animation sub-event in the displayed event panel. After editing is completed, the animation editor updates the queried animation sub-events based on the event information in the event panel.

Along the above example, assume that two basic animation sub-events, namely, a binding object A and a following object B, and three extended animation sub-events, namely, a kicking sub-event, a nodding sub-event and a waving sub-event, have been created for actor 1. Specifically, as shown in fig. 4, in the event operation region in the animation editor, the binding object a corresponds to the event operation sub-region cr1, the following object B corresponds to the event operation sub-region cr2, the kicking event corresponds to the event operation sub-region cr3, the nod event corresponds to the event operation sub-region cr4, and the hand waving event corresponds to the event operation sub-region cr5. These animation sub-events are presented within the event manipulation area of the animation editor in the manner of event manipulation sub-areas. Receiving an event query instruction submitted by a user U in an event operation area, traversing an event quadtree created in advance for the event operation area and event operation sub-areas of 5 animation sub-events, comparing the position information d1 carried in the event query instruction with the 5 event operation sub-areas corresponding to the nodes of the event quadtree, determining that the position information d1 is matched with the event operation sub-area cr4, and displaying an event panel corresponding to a nod sub-event corresponding to the event operation sub-area cr 4.

In conclusion, the animation sub-events to be checked are queried in a traversing mode of the quadtree, so that the query efficiency of the animation sub-events corresponding to the query instruction of the query event is improved.

In specific implementation, each created animation sub-event needs to be included in the event quad-tree, in order to avoid that the event quad-tree needs to be reconstructed after a new animation sub-event is created each time, a new animation sub-event can be created each time, and the created event quad-tree is updated based on the event operation sub-region of the newly created animation sub-event, and in the embodiment of the present application, the event quad-tree is updated by the following ways:

In practical application, since each leaf node in the event quadtree corresponds to a piece of node area in the event operation area, and each leaf node corresponds to the event operation sub-area contained in the piece of node area. Therefore, it is necessary to determine the node area where the position of the operation event sub-area of the newly created animation sub-event (base animation sub-event or extension animation sub-event) is located, and then determine the corresponding target node of the located node area in the event quadtree. And updating the event quadtree by adding the position of the operation event sub-region of the newly created animation sub-event to the target node for updating, thereby obtaining the updated event quadtree. For example, the target node originally corresponds to 1 event operation sub-region, and after the target node is updated through the operation event sub-region of the newly created animation sub-event, the target node corresponds to 2 event operation sub-regions.

Along the above example, it is assumed that there are 4 leaf nodes in the event quadtree, and the 4 leaf nodes are respectively a leaf node a, a leaf node B, a leaf node C and a leaf node D, where the leaf node a corresponds to the event operation sub-region cr1, the leaf node B corresponds to the event operation sub-region cr3, the leaf node C corresponds to the event operation sub-region cr2, and the leaf node D corresponds to the event operation sub-region cr4. After the extended animation sub-event, namely the hand swing sub-event, is created, determining that an event operation sub-region cr5 of the hand swing sub-event is in a node region corresponding to the leaf node C, and taking the leaf node C as a target node. The leaf node C originally corresponds to the event operation sub-region cr2 of the follower object B, and updates the leaf node C by adding the event operation sub-region r5 to the leaf node C, where the updated leaf node C corresponds to the event operation sub-region cr2 of the follower object B and the event operation sub-region cr5 of the hand swing event. Further, by updating the leaf node C in the event quadtree, an updated event quadtree is obtained.

In sum, after the event quadtree is created for the first time, the event quadtree is only updated through the event operation sub-region corresponding to the newly created animation sub-event after the animation sub-event is created each time, so that the efficiency of viewing the event is indirectly improved.

And 206, creating a target animation file based on the animation object, the animation track and the animation event.

Specifically, on the basis of the above-described read animation event, in order to include all animation elements in the created target animation file, a playable animation (i.e., target animation file) is created based on animation elements such as animation objects, animation tracks, and animation events.

When the method is implemented, a blank initial animation file can be created first, then animation data corresponding to an animation object, an animation track and an animation event are read from a memory, and the animation data are added to the initial animation file according to a preset format to generate a target animation file. Furthermore, the playing interface can be called to play the target animation file so as to play the created target animation.

In order to make the created target animation file include all animation elements created in the animation editing process on the basis that the animation track is divided into an active picture track and a sub-animation track, and the animation event is divided into a basic animation event and an extended animation event, the embodiment of the application creates the target animation file based on the animation object, the active picture track, the basic animation event, the sub-animation track and the extended animation event. The created target animation file has clear level and stronger interpretability. In the implementation, in the process of editing and creating the animation through the animation editor, some animation resources of preset types in the animation editor, such as material resources, map pasting resources, animation editing resources and the like, which are pre-imported or configured in the animation editor, are possibly referred to, if only the reference relationship is directly saved for the resources in the process of creating the animation file, the migration of the animation file is not facilitated, so that the resource information of the referred original resources can be directly saved in the animation file, and the embodiment of the application is realized in the following manner:

The preset type refers to a preset resource type of the animation resource. In practical application, the resource type independent to the animation editor can be set as a preset type, and in this case, the resource information in the animation editor is also easy to read, so that the resource information of the animation resources can be directly read.

In practice, the created animation objects, animation tracks and animation events are taken as animation elements, and each of the animation elements possibly refers to animation resources, so that the animation elements associated with the animation resources of the preset type are selected as at least one target animation element in the animation objects, the animation tracks and the animation events. So as to read animation resources of a preset type (i.e., target animation resources) associated with (referenced by or dependent on) the target animation elements and to read resource information of the target animation resources.

And updating the target animation elements with the association relationship by the read resource information according to the association relationship (the reference relationship or the dependency relationship) between the target animation resources and at least one target animation element. And updating the animation object, the animation track and the animation element corresponding to the animation object, the animation track and the animation event based on the updated at least one target animation element to obtain updated animation elements so as to create a target animation file based on the updated animation elements.

Along the above example, an animation creation instruction submitted by the user U is received, and in response to the animation creation instruction, all animation objects created in the animation editor are determined, including actor 1, director 1, and camera 1, and a base animation event created in advance for the active picture tracks corresponding to the three animation objects is read, including binding object a (base animation sub-event) in the base animation event. And selecting an animation object, namely actor 1, of the three animation objects, wherein the animation object is associated with the sub-animation track, and taking the animation object, namely actor 1, as a target animation object. And reads an extended animation event created in advance of an action track (sub-animation track) associated with the target animation object actor 1, the extended animation event including a kick sub-event (extended animation sub-event).

And taking three animation objects, an active drawing track corresponding to the three animation objects, an action track associated with the actor 1, a binding object A and a kicking event as animation elements, and determining that a target animation element associated with animation resources of a preset type in the animation elements is the binding object A under the condition that animation resources of a preset type are preset in the animation elements, wherein the preset type is a map type and a material type. And determining the (associated) target animation resource of the preset type configured in the binding object A as a file A, and reading file information contained in the file A. And updating the binding object A based on the read file information to obtain the updated binding object A.

In summary, the target animation file is convenient to migrate by reading the resource information of the target animation resource associated with the target animation element and updating the target animation element based on the resource information so that the created target animation file directly contains the resource information of the animation resource.

In addition, the animation element also contains animation elements related to the prefabricated member resources, and the prefabricated member resources are created in advance through an animation editor, and the stored information needs to be analyzed by the animation editor, so that the resource paths of the prefabricated member resources can be saved for avoiding the analysis of the prefabricated member resources, and the embodiment of the application is realized in the following way:

Because the dependency of the prefabricated member resources on the animation editor is larger, the difficulty in reading the resource information is larger, particularly, the animation editor is used as a plug-in editor, and the resource information in the prefabricated member resources is difficult to analyze under the condition that the original editor corresponding to the plug-in editor is pre-created, so that the resource paths of the prefabricated member resources can be directly determined.

In practice, the created animation object, the active drawing track, the basic animation event, the sub-animation track and the extended animation event are taken as animation elements, and each of the animation elements can possibly refer to the prefabricated member resource, so that the animation element associated with the prefabricated member resource needs to be selected as at least one prefabricated member animation element in the animation object, the active drawing track, the basic animation event, the sub-animation track and the extended animation event. To determine the resource path of the target preform resource to which these preform animation elements are associated (referenced or dependent).

And updating the prefabricated member animation elements with the association relationship through the determined resource path according to the association relationship (the reference relationship or the dependency relationship) between the target prefabricated member resource and at least one prefabricated member animation element. And updating the animation objects, the animation tracks and the animation elements corresponding to the animation objects, the animation tracks and the animation events based on the updated at least one prefabricated member animation element to obtain updated animation elements so as to create a target animation file based on the updated animation elements.

Along the above example, three animation objects, the active drawing track corresponding to the three animation objects, the action track associated with actor 1, the binding object A and the kicking event are taken as animation elements, and the prefabricated member elements associated with the prefabricated member resources in the animation elements are determined to be actor 1. A (associated) target pre-cast asset file B configured in the actor 1 is determined, and an asset path p1 of the target pre-cast asset file B is determined. And updating the actor 1 based on the resource path p1 to obtain the updated actor 1.

In summary, by determining the resource path of the target pre-form resource associated with the pre-form animation element and updating the pre-form animation element based on the resource path, so that the created target animation file directly contains the resource path of the pre-form resource, the generation efficiency of generating the target animation file is ensured.

In summary, the animation generation method provided by the embodiment of the application determines the created animation object based on the received animation creation instruction, reads the animation event created in advance for the animation track corresponding to the animation object, creates the target animation file based on the animation object, the animation track and the animation event according to the hierarchical structure of the animation object, the animation track and the animation event, realizes the creation of the target animation file according to the hierarchical structure of the animation track and the animation event corresponding to the animation object, ensures that the animation hierarchy is more visual and convenient to understand, improves the efficiency of creating the animation for the user, and improves the creation experience of the user.
