Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In order to solve the above technical problem, an embodiment of the present invention provides a method for synchronizing scene data. In the method, a plurality of clients can apply a plurality of sub-scene files which are stored in a server and belong to the same game scene, and any client can be used as a first client or a second client. Fig. 1 is a flowchart illustrating a scene data synchronization method according to an embodiment of the present invention. Referring to fig. 1, the synchronization method of scene data includes steps S102 to S106.
And step S102, the second client receives the sub-scene file which is sent by the server and edited by at least one first client and has the appointed universal format, and the appointed universal format is a file format which can be commonly used by all the clients.
In the embodiment of the present invention, the specified common Format may be u3f (Universal 3D Format) Format. After the first client edits any sub-scene file, the edited sub-scene file can be saved as a sub-scene file in the u3f format, and the second client can edit and modify the sub-scene file in the u3f format. The number of the second clients receiving the sub-scene file in the common format pushed by the server in this embodiment may also be multiple, which is not specifically limited in this embodiment of the present invention.
And step S104, extracting scene resources from the received sub-scene files through the engine editor, and converting the extracted scene resources into an engine internal format.
And step S106, constructing a scene structure and generating a scene object based on the scene resources in the internal format of the engine and the scene tree in the sub-scene file.
In the embodiment of the invention, after the sub-scene file is edited by at least one first client and stored as the sub-scene file in the specified general format, the edited sub-scene file in the specified general format can be synchronized to a second client by the server, the scene resource in the sub-scene file is converted into the internal format of the engine by the engine editor of the second client, and then the scene structure can be constructed and the scene object can be generated based on the scene resource in the internal format of the engine and the scene tree in the sub-scene file.
Therefore, the universal format data synchronized among different clients in the embodiment of the invention can be compatible with all clients, the loading performance of the scene resources is ensured, the expansion and modification of the clients can be effectively supported, the scene resources are cooperatively edited by a plurality of first clients, the editing efficiency of the scene resources is improved, and the cooperative editing capability of the scene resources is also effectively improved by adopting the universal format data. Moreover, by synchronously pushing the sub-scene files edited by any client to other clients, the scene data is effectively synchronized among the clients in time, and the relevance among different clients is promoted.
The embodiment of the invention can be applied to the production of the scene file, namely the production link of the scene file in the game production process, and the scene file in the game can be produced and edited cooperatively through a plurality of clients. For example, in the game production process, a plurality of sub-scene files contained in the scene file of the same game scene can be produced and edited cooperatively by different clients, and different clients can produce and edit different sub-scene files, so that the production efficiency of the whole scene file is effectively improved, and the production efficiency of the whole game is improved.
The client of the embodiment of the invention can adopt maya software, a client based on an Engine Unity and a client based on a Unreal Engine universal Engine, any client can be used as a first client or a second client, and any client can edit the sub-scene file and also can receive the sub-scene file in a specified universal format edited by other clients synchronized by the server.
In the embodiment of the invention, the scene resources contained in the sub-scene file adopt an extensible resource object storage structure, namely, the resource objects BaseObject are taken as specific units for resource storage. Each resource object BaseObject contains an object name and object content, the resource object may contain various basic resource types, and the object content may specifically include a plurality of object attributes and reference relationships with other objects. The object attributes may include attributes such as a vertex position attribute, a vertex normal attribute, a vertex color attribute, and the like, and the values of the object attributes include a resource default value and a value corresponding to time.
Now, taking grid Mesh resources derived from the resource object BaseObject as an example, a Mesh resource object storage structure is introduced.
Where Define is a key indicating a Mesh type (a type derived from BaseObject) defining an object name "Cube", Float3 indicates a vector whose type of attribute is a set of three floating point data floats, and the type of attribute includes a vertex position points, a vertex normal, and a vertex color. Samples represents a set of values with time information, where each value is a time to a set of vertex data.
The resource object BaseObject of the embodiment of the invention is a parent class, and the Mesh is a subclass. Of course, the resource object BaseObject may also derive other sub-classes, such as a spatial transform object, a material object, a camera object, a light object, a particle object, a terrain object, and so on. The resource object derived from BaseObject may include a parent attribute or an attribute unique to the resource object. The embodiment of the present invention does not specifically limit the types and attributes of the resource objects.
The embodiment of the invention can adopt a tree hierarchy structure on the whole scene configuration, and each hierarchy node is a resource object BaseObject. The resource object BaseObject may represent a node of a space transformation object, may also represent a node of a resource used for rendering, such as a grid resource Mesh, a Material resource, a bone resource skeeleton, an Animation resource, and may also represent other types of nodes such as a camera and a light, and may even extend nodes such as a special effect and a terrain, such as a particle system.
In one embodiment, the nodes of a portion of the hierarchy in the tree hierarchy are defined as follows:
define is a keyword and represents object names defining resource objects, and each object name corresponds to one node. The hierarchy nodes in the above embodiments include a node of a spatial transformation resource with an object name of "Building", a node of a spatial transformation resource with an object name of "House 1", a mesh node with an object name of "Chair", a mesh node with an object name of "Floor", a node of a spatial transformation resource with an object name of "House 2", and the like.
In addition, referring to fig. 2, each scene object in the overall game scene SubScene implemented by the present invention may be used as a root node RootSubScene of a sub-scene. The sub-scene file contains a sub-scene structure and a pure resource file, and the sub-scene structure references the pure resource file. Fig. 2 shows the sub-scene structure SubScene1 and the sub-scene structure SubScene2, the resource file ResourceFile1, the resource file ResourceFile2, the resource file ResourceFile 3. And the sub scene structure SubScene1 references resource file ResourceFile1 and resource file ResourceFile2, and the sub scene structure SubScene2 references resource file ResourceFile2 and resource file ResourceFile 3. Since the resources and the scene structures contained in different scenes are different, the reference relationship of the scene structure to the resources may be determined according to actual requirements, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the present invention, a plurality of sub-Scene files SubScene of a Scene may be combined to represent a complete Scene or level. Moreover, the sub-scene files are relatively independent, the editor of one first client can operate one sub-scene file independently, and a plurality of first clients can collaboratively edit a plurality of sub-scene files by adopting a plurality of editing modes.
In this embodiment, the editing manner for the resource object in the sub-scene file may include at least one of a definition operation (Define), an Overwrite operation (Overwrite), and a Reference setting operation (Reference).
The definition operation may refer to the definition operation of the resource object (object name is Cube) in the above embodiment.
The rewriting operation corresponds to the defining operation, and one resource object in the sub-scene file is rewritten, namely the resource object BaseObject is redefined.
When the resource object reference relation is set, the reference information of the referenced resource object BaseObject can be directly added, and other referenced resource objects do not need to be completely copied, so that the reference efficiency can be improved, and the reference mode can be used for the reference of the scene node to the resource object.
The rewriting operation of the resource object will now be described by taking the Mesh resource derived from the rewriting resource object BaseObject as an example.
Wherein, Overwrite represents the Mesh type with the name of Charr 2 rewritten, and the suffix ss in building.ss is the abbreviation of SubScene, which represents the sub-scene file. </building/House 1/Charr > is a full path of a Charr node in a sub-scene file, and the full path is used as a unique identifier of a certain node. This embodiment overwrites the vertex position data.
In addition, the editing operation of the sub-scene file in the embodiment of the invention can also comprise adding a tangent attribute to the resource object and configuring an algorithm for calculating the tangent. Topology attributes may also be added to attributes of the resource object, such as removing vertex color attributes, adding an association with another object Material, and so forth. The editing mode of the sub-scene file is not particularly limited in the embodiment of the invention. The editors of the plurality of first clients can simultaneously and cooperatively work, so that the editing efficiency of the scene data can be improved.
In addition, before editing the sub-scene file, the embodiment of the invention can also traverse and analyze the attribute of the resource object in the sub-scene file through the data format analyzer, and the attribute of the resource object in the sub-scene file can be analyzed through the data format analyzer, so that the follow-up editing and expansion of the sub-scene file can be facilitated.
In an embodiment of the present invention, a client plug-in may be used to convert the format of the scene data into the specified general format of the embodiment of the present invention. Because each client using the sub-scene file of the same scene has respective characteristics, and the own data formats of different clients are not communicated, the embodiment of the invention respectively sets corresponding client plug-ins for the clients using the sub-scene file of the same scene. The client plug-in may convert formatted data such as FBX, OBJ, DAE, etc. to the universal u3f format. The embodiment of the invention can effectively realize the contact of each client by converting the scene data into the appointed universal format through the client plug-in.
Each client plug-in can be used as an independent client and logs in a server, the server maintains the connection with the client plug-in, the client can map the file of the server to a local disk through the corresponding plug-in and can edit the sub-scene file.
For example, referring to fig. 3, the clients using the same game scene in the embodiment of the present invention are maya software, an Engine Unity-based client, and a ghost Engine non-Engine (UE) -based client, respectively. The plug-in Maya plug-in set for the Maya software may convert the data format of the Maya software into the u3f format, the plug-in Unity plug-in set for the engine Unity-based client may convert the data format of the Unity client into the u3f format, and the plug-in UE plug-in set for the UE client may convert the data format of the UE client into the u3f format. Any client can be used as a first client to edit the sub-scene file, and can also be used as a second client to receive the edited sub-scene file.
In the embodiment, it is assumed that the UE client edits the sub-scene file, and after the UE client maps the sub-scene file stored in the server to the local disk and edits the sub-scene file, the UE plug-in converts the edited sub-scene file into the sub-scene file in the u3f format, and then feeds back the sub-scene file in the u3f format to the server and stores the sub-scene file in the server. And the server pushes the sub-scene file in the u3f format to Maya software through a plug-in Maya plug-in and pushes the sub-scene file to a Unity client through a Unity plug-in. Therefore, the maya software and the Unity client can update the locally mapped sub-scene file according to the obtained new sub-scene file. Furthermore, the maya software and the Unity client can convert the scene resources in the received sub-scene file into an engine internal format through respective engine editors, and reconstruct the scene structure based on the resources of the engine internal format and the scene tree and generate the scene object.
Therefore, the embodiment of the present invention provides a solution (Universal Data solution, uds) for providing collaborative editing preview for clients based on a specified general format (e.g., u3f format), that is, any client edits sub-scene files and converts the sub-scene files into general format sub-scene files to upload to a server, and the server synchronizes the edited sub-scene files in the specified general format to all connected clients, thereby implementing intercommunication of scene Data among different clients, that is, implementing synchronous update and display of scene Data among different clients.
In an embodiment of the present invention, the sub-scene file stored in the server may adopt a text format or a two-level system format. And storing the sub-scene files in the text format according to the logical relationship of the scenes. The scene data in the sub-scene file in the two-level system format comprises three data of a scene structure, a resource default value and a resource time information value, and the priority is the scene structure, the resource default value and the resource time information value from high to low in sequence. The secondary system format can enable the memory space occupied by the sub-scene file to be smaller, and can also ensure that the minimum amount of data can be obtained most efficiently when the data is loaded by setting the priority level of the data.
In the embodiment of the present invention, the sub-scene file received by the second client includes a resource and a scene tree, and the second client may convert the scene resource and create the scene structure again according to the resource and the scene tree. Therefore, when the second client may extract the scene resource from the received sub-scene file through the engine editor and convert the extracted scene resource into the engine internal format, the second client may extract the scene resource from the received sub-scene file through the engine editor and save the extracted scene resource into the newly generated sub-scene file. And further, converting the scene resources in the newly generated sub-scene file into an engine internal format.
The scene resources of this embodiment are saved in units of resource objects, and thus it is possible to extract resource objects from the sub-scene file and save the extracted resource objects to the newly generated sub-scene file. The resource data is relatively fixed and can be reused by different sub-scenes, so that after a new sub-scene file is extracted, the resource data can be conveniently used by other sub-scenes.
When the scene resources in the newly generated sub-scene file are converted into the internal format of the engine, the embodiment of the invention can adopt a parallelization tool to convert the scene resources in the newly generated sub-scene file into the internal format of the engine, and the parallelization tool is not specifically limited by the embodiment of the invention.
In addition, the embodiment of the invention can also adopt a multithreading mode to convert the scene resources in the newly generated sub-scene file into an engine internal format in parallel.
