This article describes how to debug Lua in Unity. The specific solution is to use IntelliJ IDEA + EmmyLua.
step
Download and install IntelliJ IDEA https://www.jetbrains.com/idea/
Download EmmyLua, https://plugins.jetbrains.com/plugin/9768-emmylua
Open the plugins setting interface in IDEA (or enter File -> Settings -> Plugins from the menu),
click Install plugin from disk, select the downloaded LuaIDE-XXX.zip file, and restart IntelliJ IDEA after installation.
- Create a project: the menu goes to File -> New -> Project
- Set the existing source directory as the Sources directory: the menu goes to File -> Project Structure, select Modules -> Sources -> Add Content Root -> select the source root directory -> Mark as: Sources
- Breakpoint debugging: Run Unity, open IDEA menu Run -> Attach to Local Process, select Unity.exe
some problems:
- The breakpoint is invalid, and a xxx not found log appears in the IDEA console window
- Please make sure the Sources directory is set correctly
- Attaching to target program fails with Error: LuaInject.dll could not be loaded into the process
- Check whether the injection process is blocked by anti-virus and security guards
- Associate other extensions
