[0043] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0044] The resource storage and reading method provided in this application can be applied to Figure 1 In the application environment shown. The application environment involves a first terminal 102, a second terminal 104 and a cloud server 106, wherein the first terminal 102 and the second terminal 104 both communicate with the cloud server 106 via a network. The game developer can compress and store game resource files through the first terminal 102, generate a resource compression package in a virtual file system format, and upload the resource compression package to the cloud server 106. The game user can install and run the game through the second terminal 104, and when the game is detected to be started, download the corresponding resource compression package from the cloud server 106, read the resource compression package, and obtain the corresponding game resource files. Among them, the first terminal 102 and the second terminal 104 can be, but are not limited to, various personal computers, laptops, smart phones and tablet computers, and the cloud server 106 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0045] In one embodiment, Figure 2 As shown, a resource storage method is provided, which is applied to Figure 1 Taking the first terminal in the example as an example, the method includes the following steps S202 to S206.

[0046] S202, obtaining game resource files.

[0047] Taking the Unity game development platform as an example, developers can use Unity to create a game project and develop corresponding game files under the game project. The game files include game program logic files (such as game operation logic, reading logic, etc.) and game resource files (such as sounds, pictures, animations, etc. that need to be loaded during the game operation). The first terminal can obtain the game files from Unity and process the game files.

[0048] S204, compress and store the game resource files to generate a resource compression package in a virtual file system format; the virtual file system format includes: a data storage component and a verification component, the data storage component is used to store the game resource files in blocks, and the verification component is used to store verification data of the game resource files.

[0049] The game resource files used by Unity are usually in the Assetbundle (AB) format. Game files usually contain a large number of AB format game resource files. After the first terminal obtains the AB format game resource files from Unity, it can compress and store all the AB format game resource files and package them into a resource compression package in the virtual file system (VFS) format for easy reading.

[0050] S206, uploading the resource compression package to the cloud server for downloading when the game starts.

[0051] The first terminal can process the game program logic file into an application package (apk or ipa) and upload it to the application store, and process the game resource file into a resource compression package in VFS format and upload it to the cloud server. The user can download the application package from the application store and install the corresponding game to the second terminal. When the second terminal starts the game, it downloads the corresponding resource compression package from the cloud server.

[0052] In the above-mentioned resource storage method, by compressing and storing the game resource files into a resource compression package in the virtual file system format, the game resource files can be read directly from the resource compression package later, without the need to decompress each game resource file in the resource compression package to an additional storage space for reading, thereby reducing the storage space occupied; using block storage, the game resources can be loaded and displayed without downloading all the files during reading, thereby improving the game loading efficiency; in addition, by uploading the resource compression package to the cloud server, the problem of the game installation package being too large due to packaging the game resource files together into the game installation package can be avoided, thereby improving the success rate and efficiency of the game installation.

[0053] In one embodiment, the steps of compressing and storing game resource files to generate a resource compression package in a virtual file system format may specifically include the following steps: dividing each game resource file into blocks according to a preset block length to obtain block data; calculating the first encryption information of each game resource file and the second encryption information of each block data, and determining the verification data of the game resource file based on each first encryption information and each second encryption information; and generating a resource compression package in a virtual file system format based on the block data and the verification data.

[0054] Among them, the block length can be set according to the actual situation, for example, it is set to 16K. The game resource file is stored in the form of data blocks. For example, if the length of a game resource file is 32K, then the game resource file is divided into two 16K block data for storage after block processing.

[0055] The encrypted information can specifically be an MD5 value. The first encrypted information represents the MD5 value of the game resource file, and the second encrypted information represents the MD5 value of the block data. The message digest algorithm (MD5) can generate a special string (MD5 value) from a file according to certain rules. The MD5 value corresponding to a file is fixed. When the file content changes, its MD5 value will also change. Therefore, the MD5 value can be used as the file's encryption information to verify whether the file has been tampered with.

[0056] In this embodiment, by storing the game resource files in blocks and setting encryption information for each game resource file and each block data, the game resources are not easily cracked and tampered game resources are easily identified, thereby enhancing the security of the game resources.

[0057] In one embodiment, the virtual file system format further includes: a file header component and a bitmap component, wherein the file header component is used to store file header information, and the bitmap component is used to store block information of the game resource file. The step of generating a resource compression package in the virtual file system format based on the block data and the check data may specifically include the following steps: determining the block information of the game resource file based on the number of block data; determining the file header information based on the file header length, the total length of the game resource file, the check data, and the block information; and generating the resource compression package in the virtual file system format based on the file header information, the block data, the check data, and the block information.

[0058] The block information is used to indicate whether the data block is empty data, and is stored in the form of a bitmap. The bitmap can mark whether the data block is empty data for subsequent data writing. Specifically, each data block occupies a bit in the bitmap. If the data block stores data, the bit corresponding to the data block is set to 1. If the data block is empty data, the bit corresponding to the data block is set to 0. The file header length can be a preset file header size, for example, it can be set to 172 bytes. The total length of the game resource file represents the total size of all game resource files, and the required storage capacity can be determined based on the total size of the game resource files. The verification data can be specifically stored in the form of a hash table, including a file hash table and a data hash table, which respectively store the first encryption information of the game resource file and the second encryption information of the block data.

[0059] In one embodiment, the step of determining the file header information based on the file header length, the total length of the game resource file, the check data and the block information may specifically include the following steps: determining the basic header information based on the file header length, the total length of the game resource file, the block length, the position and length of the check data, and the position and length of the block information; calculating the third encrypted information of the check data, and calculating the fourth encrypted information based on the third encrypted information and the basic header information; determining the file header information based on the basic header information, the third encrypted information and the fourth encrypted information.

[0060] The file header information includes basic header information, third encryption information, and fourth encryption information. The basic header information includes: file header length, total length of the game resource file, block length, position and length of verification data, and position and length of block information. The position and length of the verification data can specifically be the position and length of the Hash table where the verification data is located. The position and length of the block information can specifically be the position and length of the Bitmap where the block information is located. The third encryption information can specifically be the MD5 value of the Hash table where the verification data is located, which is used to verify the Hash table. The third encryption information and the basic header information are regarded as a whole file, and the fourth encryption information represents the MD5 value of the whole file, which is used to verify the file header information.

[0061] like Figure 3 As shown, a schematic diagram of a resource compression package (Res.vfs) in VFS format in one embodiment is shown. The VFS format includes the following four components: a header component (Header), a data storage component (Data Segment), a check component (HashTable) and a bitmap component (Bitmap). The Header includes: basic header information (HeaderInfo), hash table encryption information (HashTable MD5) and header encryption information (Header MD5). HeaderInfo includes: file type (dwID), file header length (HeaderSize), version information (FormatVersion), block length (MD5PieceSize), file length (Archivesize), hash table position (HashTablePos), hash table length (HashTableSize), bitmap position (BitmapPos), and bitmap length (BitmapSize). The Data Segment includes all game resource files (File), each game resource file is stored in the form of data blocks, and the size of each data block is 16K. The HashTable contains the encryption information of the game resource file (File MD5) and the encryption information of the block data (Block MD5). Specifically, when compressing and storing the game resource file, you can first create an empty VFS format file, and then write the corresponding information of each component in the order of Header, DataSegment, HashTable, and Bitmap to obtain a VFS format resource compression package.

[0062] In the above embodiment, by compressing and storing scattered game resource files into a resource compression package in a virtual file system format, the integrity of the game resources can be enhanced; by reading the game resource files from the resource compression package in the virtual file system format, there is no need to decompress each game resource file in the resource compression package to an additional storage space for reading, which can reduce the storage space occupied; by storing the game resource files in blocks and setting verification data, it helps to identify tampered resources, which can enhance the security of the game resources; by uploading the resource compression package to the cloud server, the capacity of the game installation package or update package can be greatly reduced, lowering the threshold for new game entrants.

[0063] In one embodiment, Figure 4 As shown, a resource reading method is provided, which is applied to Figure 1 Taking the second terminal in as an example, the method includes the following steps S402 to S404.

[0064] S402, when the game is started, the corresponding resource compression package is downloaded from the cloud server; the resource compression package represents a resource compression package in a virtual file system format generated after compressing and storing the game resource files, and the virtual file system format includes: a data storage component and a verification component, the data storage component is used to store the game resource files in blocks, and the verification component is used to store the verification data of the game resource files.

[0065] S404: Read the resource compression package to obtain the corresponding game resource file.

[0066] In the above-mentioned resource reading method, when the game is started, the corresponding resource compression package is downloaded from the cloud server. The resource compression package is a resource compression package in a virtual file system format generated by compressing and storing the game resource files of the started game. The game resource files can be read directly from the resource compression package without decompressing each game resource file in the resource compression package to an additional storage space for reading, thereby reducing the storage space occupied; using block storage, the game resources can be loaded and displayed without downloading all files during reading, thereby improving the game loading efficiency; in addition, by downloading the resource compression package from the cloud server, the problem of the game installation package being too large due to packaging the game resource files together into the game installation package can be avoided, thereby improving the success rate and efficiency of game installation.

[0067] In one embodiment, a method for generating a resource compression package in a virtual file system format includes the following steps: segmenting each game resource file into blocks according to a preset segment length to obtain segmented data; calculating first encryption information for each game resource file and second encryption information for each segmented data; determining verification data for the game resource file based on each first encryption information and each second encryption information; and generating a resource compression package in a virtual file system format based on the segmented data and the verification data. The specific description of this embodiment can be found in the previous embodiment and will not be repeated here.

[0068] In one embodiment, the virtual file system format further includes: a file header component and a bitmap component, wherein the file header component is used to store file header information, and the bitmap component is used to store block information of the game resource file; the step of generating a resource compression package in the virtual file system format based on the block data and the check data may specifically include the following steps: determining the block information of the game resource file based on the number of block data; determining the file header information based on the file header length, the total length of the game resource file, the check data, and the block information; and generating a resource compression package in the virtual file system format based on the file header information, the block data, the check data, and the block information. The specific description of this embodiment can be referred to the previous embodiment and will not be repeated here.

[0069] In one embodiment, the step of determining the file header information based on the file header length, the total length of the game resource file, the check data, and the block information may specifically include the following steps: determining the basic header information based on the file header length, the total length of the game resource file, the block length, the position and length of the check data, and the position and length of the block information; calculating third encrypted information of the check data, and calculating fourth encrypted information based on the third encrypted information and the basic header information; and determining the file header information based on the basic header information, the third encrypted information, and the fourth encrypted information. The specific description of this embodiment can be referred to the previous embodiment and will not be repeated here.

[0070] In one embodiment, the step of reading the resource compression package to obtain the corresponding game resource file may specifically include the following steps: reading the file header information in the resource compression package based on the file header length; verifying the file header information based on the fourth encryption information, and after the verification passes, reading the verification data in the resource compression package; verifying the verification data based on the third encryption information, and after the verification passes, determining the location and length of the game resource file; reading the block data in the resource compression package based on the location and length of the game resource file, and obtaining the corresponding game resource file based on the read block data.

[0071] Specifically, after obtaining the resource compression package (Res.vfs) in VFS format, you can open the file handle of Res.vfs, read the first 172 bytes of Res.vfs (the file header length is 172 bytes), and obtain the file header information of Res.vfs (that is, the information included in the Header); verify the file header information based on the fourth encryption information (Header MD5), and after the verification passes, read the verification data (that is, HashTable data) in Res.vfs; verify the HashTable data based on the third encryption information (HashTableMD5), and after the verification passes, rebuild the file directory tree; determine the location and length of the game resource file according to the file directory tree; read the block data in Res.vfs according to the location and length of the game resource file, and restore the original game resource file based on the read block data.

[0072] In this embodiment, by directly reading the game resource files in the resource compression package, there is no need to decompress each game resource file in the resource compression package to an additional storage space for reading, thereby reducing the storage space occupied. Compared with reading multiple scattered game resource files separately, the reading efficiency can be improved, thereby improving the game loading efficiency and reducing user waiting time.

[0073] In one embodiment, the step of reading the resource compression package to obtain the corresponding game resource file can specifically be: calling the virtual file system format reading plug-in, reading the resource compression package based on the virtual file system format reading plug-in instance, and obtaining the corresponding game resource file.

[0074] In this embodiment, the VFS format reading plug-in is called, and the resource compression package is read based on the VFS format reading plug-in instance, so that the resource compression package can be read according to the reading method defined in the VFS format reading plug-in instance, thereby realizing direct reading of the VFS file.

[0075] like Figure 5 As shown, a schematic diagram of a Unity plug-in use case in an embodiment is provided. The Unity plug-in system can take over the underlying Unity file system to implement a direct read solution for VFS files, while this read solution is transparent to upper-level users. Specifically, the VFS library is first referenced to the Unity Plugin. During initialization, a VFS read plug-in instance is created. The VFS format read plug-in instance is registered with the Unity file system through FileSystem::MountHandler (VFS format read plug-in instance). When Unity loads AB format files, the path prefix is ​​vfs: / / . In this way, when reading AB format files, it will read according to the read method defined in the VFS format read plug-in instance.

[0076] This application also provides an application scenario, which applies the above-mentioned resource storage and reading method. Specifically, Figure 6 As shown, the application of the resource storage and reading method in this application scenario is as follows:

[0077] The developer checks out the Unity project from Git or SVN to the first terminal. The first terminal processes the game resource files in the Unity project into a resource compression package (Res.vfs) in the virtual file system format, processes the game program logic files into an application package (mini.apk), and simultaneously generates a version upgrade configuration file (config). The first terminal uploads Res.vfs to the cloud server, updates the config to the policy server, and uploads the mini.apk to the app store. The user downloads the mini.apk from the app store and installs it on the second terminal. When the second terminal launches the game corresponding to the mini.apk, it first obtains the current latest program version from the policy server and then downloads Res.vfs from the cloud server. This download can only download incremental data, without downloading the entire file. After a successful download, the second terminal performs an integrity check on Res.vfs. If the check passes, it reads the game resource files in Res.vfs to load game-related content.

[0078] It should be understood that although Figure 2 、 4 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.
