GDScript warning system

The GDScript warning system complements static typing (but it can work without static typing too). It’s here to help you avoid mistakes that are hard to spot during development, and that may lead to runtime errors.

You can configure warnings in the Project Settings under the section called GDScript:

Note

You must enable Advanced Settings in order to see the GDScript section in the sidebar. You can also search for “GDScript” when Advanced Settings is off.

You can find a list of warnings for the active GDScript file in the script editor’s status bar. The example below has 2 warnings:

To ignore specific warnings in one file, insert an annotation of the form @warning_ignore("warning-id"), or click on the ignore link to the left of the warning’s description. Godot will add an annotation above the corresponding line and the code won’t trigger the corresponding warning anymore:

Warnings won’t prevent the game from running, but you can turn them into errors if you’d like. This way your game won’t compile unless you fix all warnings. Head to the GDScript section of the Project Settings to turn on this option to the warning that you want. Here’s the same file as the previous example with the warning unused_variable as an error turned on:
