[0064] The present application provides a ParaX file parsing method, system, device and computer storage medium for implementing file parsing of ParaX files.

[0065] It should be noted that the ParaX file parsing method provided in this application can be applied to a terminal or a server. For example, the terminal can be a smart phone or a computer, a tablet computer, a smart TV, a smart watch, a portable computer terminal, or a fixed terminal such as a desktop computer. For the convenience of explanation, this application uses the terminal as the execution subject for example.

[0066] See also Figure 1 , Figure 1 An embodiment of the ParaX file parsing method provided by the present application, the method comprising:

[0067] 101. Load ParaX file;

[0068] NPL is a general open source language. Its design is based on the structure of human neural network. ParaEngine is a game engine designed based on NPL. ParaEngine customizes a file in ParaX format. This file defines properties such as bones, skin meshes, skeletal animations, animation sequences, and animation speeds. It is a file format with animated 3D character resources unique to Paraengine. ParaX is similar to a simplified version of the FBX file. The FBX file is a general 3D model file format. The FBX file format supports all major 3D data elements as well as 2D, audio, and video media elements. ParaX is built based on the ".x" file under the Microsoft platform. ParaX can provide more functions and support customized content. It should be noted that ParaX is well compatible with DirectX, and ParaX files can be viewed or modified by any commercial software that supports DirectX.

[0069] When parsing a ParaX file, the terminal first loads the ParaX file and reads and loads the resource file.

[0070] 102. Identify a target parser matching the ParaX file, and call the target parser to read the file header and file body of the ParaX file;

[0071] When loading and processing files, the terminal will allocate the corresponding parser by searching the file name type. Specifically, it collects information by mobilizing the lower-level ContentLoaderParaX (ParaX content loader) to perform the reading and loading of resource files. When loading and processing files, ContentLoaderParaX will allocate the corresponding parser by searching the file name type. For standard ParaX format files, the terminal will identify the target parser that matches the ParaX file, that is, the ParaXSerializer parser. The terminal calls the ParaXSerializer parser to perform file reading, writing and file parsing. The ParaXSerializer parser is the core part of ParaX parsing, and consists of two parts: ParaXSerializer (file reading and writing) and ParaXPraser (file parsing). ParaXSerializer first reads the file header and file body of the ParaX file.

[0072] The parsing structure of ParaX is shown in the following code:

[0073]

[0074] 103. Parse the file header and determine whether the ParaX file is legal based on the parsing result. If so, execute step 104.

[0075] After reading the file header and file body of the ParaX file, the file header of the ParaX file needs to be parsed, and the file header is parsed to determine whether the ParaX file is legal. The file header of the ParaX file includes the file size, version, format (binary, text or compressed file), etc. ParaX files can be text-based for easier editing, or binary-based, which makes the file smaller and easier to protect from prying eyes.

[0076] Specifically, the terminal determines whether the ParaX file is legal by judging whether the parsing result of the file header matches the preset valid parameters. If the parsing result of the file header matches the preset valid parameters, the ParaX file is determined to be legal, and step 104 is executed to parse the ParaX file. Otherwise, it is illegal. If it is illegal, the terminal needs to terminate the parsing of the ParaX file and report an error.

[0077] The code for the ParaX file header parsing part is shown in the following code:

[0078]

[0079] 104. Extracting a first target parameter from the parsing result;

[0080] When the terminal determines that the ParaX file is legal, it extracts the first target parameter from the parsing result of the ParaX file header. The first target parameter includes some template parameters, such as ParaXHeader (ParaX file header template), ParaXBody (ParaX file body template), XDWORDArray (double integer array template), ParaXRefSection (ParaX reference plane template), D3DRMMesh (grid template) or D3DRMFrame (frame template), etc.

[0081] 105. Parse the file body according to the first target parameter.

[0082] All the contents of the ParaX file are stored in the template, and parsing the ParaX file is to read the contents in the template. Therefore, the terminal parses the file body of the ParaX file according to the first target parameter and other resources needed to complete the parsing of the ParaX file.

[0083] In this embodiment, the parsing of ParaX format files depends on ParaXSerializer, i.e., ParaX serializer. For ParaX format files, it is first necessary to read the file header and file body of the ParaX file, and determine whether the ParaX file is legal based on the file header. When it is determined that the ParaX file is legal, the first target parameter required for subsequent parsing of the file body is obtained by parsing the file header, and the file body is parsed according to the first target parameter, thereby realizing the parsing of the ParaX file.

[0084] The following is a detailed description of the ParaX file parsing method provided by this application. Figure 2 , Figure 2 Another embodiment of the ParaX file parsing method provided by the present application includes:

[0085] 201. Load ParaX file;

[0086] 202. Identify a target parser matching the ParaX file, and call the target parser to read the file header and file body of the ParaX file;

[0087] 203. Parse the file header and determine whether the ParaX file is legal based on the parsing result. If not, execute step 204. If yes, execute step 205.

[0088] Steps 201 to 203 in this embodiment are similar to steps 101 to 103 in the aforementioned embodiment, and are not described again here.

[0089] 204. Terminate parsing and report an error;

[0090] When the terminal determines that the ParaX file is illegal, the terminal terminates parsing of the ParaX file and reports an error.

[0091] 205. Extract the first target parameter and the second target parameter from the parsing result;

[0092] In this embodiment, when the terminal determines that the ParaX file is legal, the first target parameter is extracted from the parsing result of the ParaX file header. The first target parameter includes some template parameters, such as ParaXHeader (ParaX file header template), ParaXBody (ParaX file body template), XDWORDArray (double integer array template), ParaXRefSection (ParaX reference plane template), D3DRMMesh (grid template) or D3DRMFrame (frame template), etc.

[0093] In addition, the terminal also needs to extract a second target parameter, which refers to some parameters used in the resource release part. The second target parameter and the first target parameter contain overlapping parts, which are not specifically limited here.

[0094] It should be noted that the parameter extraction part needs to be completed first in the ParaX file parsing process. Failure to complete or fail will terminate the subsequent parsing operations and report an error.

[0095] 206. Determine the type of the model in the file body, the type of the model includes an animation model and a static model;

[0096] In ParaX files, ParaX models are divided into two categories: animation and static. Animation models refer to models that contain animation actions, and the analysis of animation models focuses on animation configuration. Static models refer to models that do not contain animations, and the analysis of static models focuses on overall texture laying, rendering, and related physical information loading.

[0097] 207. Parsing the document body according to the first target parameter and the type of the model;

[0098] The terminal parses the ParaX file body according to the type of the model and the first target parameter.

[0099] Part of the code for file body parsing is shown in the following code:

[0100]

[0101]

[0102] 1. When the terminal determines that the model in the ParaX file body is an animation model:

[0103] Detailed animation configuration is required for the analysis of the animation model. The terminal performs the following operations:

[0104] Analyzing the first file information in the file body;

[0105] Read the file resource according to the type of the first file information;

[0106] Configure the model for animation based on the file resources and the first target parameters.

[0107] The terminal first analyzes the first file information in the file body, which may include XVertices vertex information, XTextures texture information, XAttachments attachment information, XTransparency transparency information, XViews perspective information, XRenderPass rendering information, XBones skeleton information, ParticleEmitters particle information, XColors shader information, XCameras camera information, XLights light information and XAnimations animation information. The terminal then reads the corresponding file resources from the database according to the first file information, and finally performs detailed animation configuration.

[0108] 2. When the terminal determines that the model in the ParaX file body is a static model:

[0109] For the analysis of static models, no animation configuration is required. The terminal performs the following operations:

[0110] Analyzing the second file information in the file body;

[0111] Read the file resource according to the type of the second file information;

[0112] The model is statically configured according to the file resources and the first target parameters.

[0113] The terminal first analyzes the second file information in the file body. The difference between the second file information and the first file information is that it does not contain animation information and other file information related to the animation configuration. The terminal reads the corresponding file resources from the database according to the second file information, and then displays the static model based on these file resources.

[0114] 208. Release resources according to the second target parameter.

[0115] In this embodiment, after the terminal completes parsing the file body, it is also necessary to release some resources according to the second target parameter extracted from the file header. The code for the resource release part is shown in the following code:

[0116]

[0117] In this embodiment, for a file in ParaX format, the file header and file body of the ParaX file need to be read first, and whether the ParaX file is legal is determined based on the file header. When the ParaX file is determined to be legal, the first target parameter required for subsequent parsing of the file body and the second target parameter used in the resource release part are obtained by parsing the file header. The file body is parsed according to the first target parameter. When parsing the file body, it is necessary to determine the type of model in the file body, and then perform specific configuration according to the type of model, and finally release resources according to the second target parameter, thereby realizing the parsing of the ParaX file.
