The content about the development of WeChat mini-games is detailed in "Unity WebGL WeChat Mini-Game Adaptation Scheme". Most of the more in-depth details will be ignored here, and you can find the answer by yourself in the address below.
The purpose of this article is to take everyone to quickly convert their existing games into WeChat mini-games.

2. Install Node
Official download address: https://nodejs.org/zh-cn/download/
3. Download the mini game plug-in
Import the unitypackage package
https://res.wx.qq.com/wechatgame/product/wasm_plugin/minigame.202302151921.unitypackage
4. Log in to the WeChat public platform and register the mini program
Address of public platform: https://mp.weixin.qq.com/
Search WeChat public platform to register an account, and register a small program (need to use an email address that has not been bound to other functions of WeChat)
5. Write game data and categories
Fill in the content in "Mini Program Information" and "Mini Program Category"
6. Get the AppID, which is the applet ID
In "Home" > "Mini Program Information" > "Basic Settings" > "Account Information", remember that it will be used later.
7. Select here, Capability Map>Production Efficiency Improvement Package>Enable High Performance Mode and Fast Adaptation
8. Download and install "WeChat Developer Tools"
Address: https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html
9. Register legal address
Set the security domain name (Development>Development Management>Development Settings>Server Domain Name)
and write all the addresses that need to be requested here, and the address to continue resource downloading, otherwise it will not be accessible. separated by;
2. Modification of the Unity project itself
The solution used here is not to load the AA package in advance, and you can skip this paragraph if you use other solutions.
Because mini-games have strict requirements on the package size, this step is mainly to change the resources into AA packages for loading, and then subpackage the content of the package body to the server to load in batches. If you don’t need subcontracting, you can choose it directly during packaging, which will be mentioned later.
10. Import Addressables in Unity
Change the synchronous loading or AB package loading in the original project to AA package asynchronous loading:
for example, modify:
to
load method:
to
11. All the package body paths can be selected by default:
Remember to build
Pay attention to the management of resource loading and unloading, which will not be described here.
3. Export project
12. Export the game package
After importing the WeChat package earlier, the "Menu Mini Game" will appear in the "Menu Bar". Select to convert the mini game.
If you are prompted to update, you must update it first.
13. View the export location
14. Upload resources
Put the contents of the webgl folder into the address of the previous step "2. External resource loading address"
15. Use WeChat developer tools to open
Click the plus sign to select the minigame selection option
in the project to open the project 4. Upload and publish
16. Upload game
When the game development and testing is completed, click here to upload
17. Test experience
In the WeChat test platform, select "Management" and "Version Management" to see the trial version just uploaded in the development version, and you can scan the code to experience it.
Due to the fact that it is not online, it may be given to designated members to experience.
18. Add testers
