how do I deal with "invalid get index 'y'"?
so I'm new to Godot and have started following the documentation not too long ago. when I arrived at the simple 2d game example, I got the following error: "invalid get index 'y' (on base Rect2)".
I thought I did everything as it was supposed to be, so I have no idea about the way to deal with this.
could someone please give me some hint?
here's a screenshot of the project:
