Warning for unused variables in class.

[FracturedRodey]

Describe the project you are working on

A 2D Game

Describe the problem or limitation you are having in your project

I want to know what variables are unused in my class. Using CTRL F for searching at the moment.

Describe the feature / enhancement and how it helps to overcome the problem or limitation

See above

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Show a warning ala IntelliJ or something when the variable is never used.

If this enhancement will not be used often, can it be worked around with a few lines of script?

Not sure if this can be done, no extension found.

Is there a reason why this should be core and not an add-on in the asset library?

It is an oveall improvement for every project.

I am assuming that this Proposal refers to the properties created outside of method definitions.
I suppose it can be done, kinda. One unique thing with Godot's Objects is that you can dynamically call, set, get properties without even referring to them directly. So the warning may yield some false-positives.

This makes total sense for variables existing in a limited scope, however.

[TheDuriel]

Go to your project settings, gdscript, warnings, and enable said warning.

[Mickeon]

There it is, then. This is no issue then, I gather?

Although, admittedly, discovering the warnings is a bit difficult, so I can understand this being missed.

[KoBeWi]

It's enabled by default tho.
