Is there a Code Analysis for Godot?

Godot Version

4.4

Question

So I’ve been coding and experimenting in Godot for sometimes, but coding is a lot of trials and errors. It is never straight forward. While the first version of the code is usable, the more we iterate the better the codes become.

But now, diving into the code takes time and the journey between each variable and function may not be straight forward in a complex project, so are there tools that could assist me further on Godot? For example, there are some Code Analysis tools for other programming languages out there that could analyze your code and report issues such as:

  • variables unused
  • possible unassigned variables
  • possible data leakage
  • suggestion and improvement for bad practice
  • etc?

variables unused

Godot will warn you about unused private variables, which start with an underscore. You will also see a warning if a variable isn’t used in a given block (function, if statement, etc.).

possible unassigned variables

You are warned about unassigned variables when you try to use them.

possible data leakage

In the Debugger panel, under the Monitors tab, there is a section for memory. If you see static memory go up over time, you may have a memory leak.

For further reading, see the GDScript warning system and Debugger panel documentation.
