DaveTheCoder You connected the mouse_entered signal to a function? Did you verify that the function is getting called at the expected time by placing a print statement in it?
Yes, these methods are executed.
DaveTheCoder Also:
Note: If you want to change the default cursor shape for Control's nodes, use Control.mouse_default_cursor_shape instead.
I don't need this. I have a custom cursor in the game, and I want to make it so that when the mouse enters the element, the cursor becomes the same as in the operating system.
