Editor crashes while using Visual Studio Code

highlander

I use Visual Studio Code to edit scripts while the Godot editor is open, and the editor occasionally crashes after making a script edit. I only have scenes open in the editor, and I only edit code in VS Code.

I've noticed after editing code in VS Code that the editor will display the following message: Another resource is loaded from path 'res://scripts/...' (possible cyclic resource inclusion)

Is there a way to prevent these editor crashes?

Godot: v3.3.3.stable.official OS: MacOS 11.6

That error usually means you have a cyclic reference somewhere in your code. For example, an object with script_a is loading a script_b object, but script_b is also loading script_a, which leads to infinite loading and then a crash. You need to be careful when you are loading resources that they don't create this sort of infinite loop.

This is in a small project with a single scene tree. Preloaded scene files are each loaded once. No scripts load other scripts, and each script is attached to a single node.

The closest thing I can see to a cyclic reference is two script files call preload with the same .png file, eg: preload("res://art/my.png")

Is that enough to cause a cyclic resource inclusion error? If it is, what is the best solution, a singleton that loads this resource that other scripts then refer to?

cybereality

That should be okay, but the problem usually happens with load or preload, so these would be the lines to check (especially when loading scenes, I think loading a png file is fine).

Thanks @cybereality. I double-checked my script file triggering this error and it only preloads .png files.

The file itself is fine. It turned out that debugging had opened the same file in Godot, and so every time code was edited in VS Code it also updated the opened version in Godot, and triggered the cyclic warning in Godot.

I can reproduce this with multiple files.

So did closing the file fix it?

Yes sorry if that wasn't clear. Closing the file in Godot stopped the cyclic warning from being generated when moving between Visual Studio and Godot.
