Documentation Usage Guide (Must Read)
Welcome to the LayaAir3 Engine Documentation
Here, you can learn about the various features and usage methods of the LayaAir3 Engine and LayaAir3-IDE.
1. Make Good Use of the Search Function
Although we strive to make the documentation structure clear and easy to navigate, if you just want to quickly find an answer when encountering a problem, the search function is the most efficient way.
For example, if you want to make the IDE interface display in Chinese, simply type “中文界面” (Chinese interface) in the search bar and press Enter to see the relevant results, as shown in Figure 1-1:

(Figure 1-1)
Click on the document title in the search results to view detailed content.
2. Choose the Correct Engine Version Documentation
When viewing documentation, many developers tend to overlook the engine version.
Different versions of the LayaAir engine (e.g., 3.1, 3.2, 3.3…) may add or modify certain features, leading to differences in usage.
Be sure to select the branch that matches your current version through the version number dropdown menu in the upper-left corner of the documentation.
For example, if you are using version 3.3.2, you should select the 3.3 branch documentation. See Figure 1-2 below:

3. Customize the Documentation Display Style
Click the A icon in the upper-left corner of the documentation to open the display settings panel, where you can adjust:
- Font size
- Font style
- Background theme
You can configure the most comfortable reading style according to your preference. See Figure 1-3 below:
