[0061] A second acquisition module is configured to sequentially split the string data of each object into a plurality of substring data according to the delimiters, and obtain the class name data, the attribute data and the type mark of the string data of each object by traversing the substring data.

[0062] A deserialization module is configured to sequentially deserialize the class name data of the string data of each object to obtain the class name data in the metadata of each object, and split the attribute data in the string data of each object to obtain the attribute name, the attribute type and the attribute value contained in the attribute data, and deserialize the attribute name, the attribute type and the attribute value contained in the attribute data to obtain the attribute data in the metadata of each object.

[0063] A recovery module is configured to construct each object in a scene according to the class name data in the metadata of each object, set the attributes of each object according to the attribute name, the attribute type and the attribute value of the attribute data in the metadata of each object, and obtain a scene containing each object and corresponding attributes.

[0064] Based on the above system, the system can further comprise a deserialization submodule, which is configured to judge the type mark in the metadata of each object, when the type mark in the string data of an object is a dynamic type, modify the class name data and the attribute data in the string data of the dynamic type object based on the attribute change of the dynamic object according to the class name data and the attribute data in the string data of the current dynamic type object, obtain the modified class name data and attribute data in the string data of the dynamic type object, and deserialize the modified class name data and attribute data in the string data of the dynamic type object to obtain the class name data and the attribute data in the metadata of the dynamic type object; when the type mark in the string data of an object is a static type, deserialize the class name data and the attribute data in the string data of the static type object to obtain the class name data and the attribute data in the metadata of the static type object.

[0065] Specifically, the recovery module comprises:

[0066] a scene construction unit configured to create each object in the scene according to the class name data in the metadata of each object;

[0067] an attribute setting unit configured to assign values to the corresponding attributes of each object according to the attribute name, attribute type and attribute value in the attribute data in the metadata of each object, to obtain a scene containing each object and the corresponding attributes.

[0068] Through the cooperation of the above components, the string data is split into structured substring data by the delimiter, and the class name data, attribute data and type tag information of the object are extracted through traversal operation.

It provides effective technical support for the loading and state restoration of scene data in Unreal Engine.

[0069] Embodiment 4

[0070] The embodiment discloses an object data deserialization system based on Unreal Engine, which comprises the following steps:

[0071] Step 1, the string data of each object is split into several substring data according to the delimiter, and the class name data, attribute data and type tag of the string data of each object are obtained by traversing the substring data;

[0072] Step 2, the class name data of the string data of each object is deserialized to obtain the class name data in the metadata of each object; the attribute data in the string data of each object is split to obtain the attribute name, attribute type and attribute value contained in the attribute data in the string data of each object, and the attribute name, attribute type and attribute value contained in the attribute data are deserialized to obtain the attribute data in the metadata of each object;

[0073] Step 3, according to the class name data in the metadata of each object, the objects in the scene are constructed, and the attributes of each object are set according to the attribute name, attribute type and attribute value of the attribute data in the metadata of each object, to obtain the corresponding scene containing each object.

[0074] It should be noted that the string data of each object is deserialized to obtain the metadata of each object. The string data of each object will be restored to a data format that can be processed by a computer, so as to perform subsequent scene recovery operations.

[0075] For example, if the property data in the string data of each object contains description information of the scene, the deserialization process will convert the data into a computer understandable format, such as a structure, an object, or a variable.

[0076] The metadata of each object contains parameters related to each element of the scene, such as lighting, shadows, camera position, etc. These parameters are matched to the parameters required by the rendering engine of the scene. This ensures consistency and quality of rendering. For example, if the rendering engine requires the position of the sun in the scene and lighting information, this information must be extracted from the string data of each object and matched to the parameters of the rendering engine. The material information of the object is extracted from the string data of each object, including texture, color, reflection properties, etc. This information will be used to ensure that the objects in the scene appear correctly. For example, if the scene description contains a tree, the scene material extraction will include the texture and color properties of the leaves and trunk. Finally, using the corrected rendering parameters, the scene can be rendered. This includes generating images, rendering animations, processing sound, etc. to present the final interactive scene, which the user will be able to interact with the rendered scene.

[0081] Step 3: Calculate the checksum of the string data of each object to obtain a first checksum

[0082] Step 4: split the string data of each object into several substring data according to the delimiter, and traverse the substring data to obtain the class name data, attribute data and type mark of the corresponding string data of each object;

[0084] Step 6, the checksum of the metadata of each object is calculated to obtain a second checksum;
