Thanks thanks, I know it sounds silly, but what Nodes and children should I use for this code? TvT, I am indebted to you.

Put the script on a Container. Make sure that the child nodes are Control-extended nodes like TextureRects or Buttons.

Dude, I’m sorry to bother you so much, because you must be busy with your own personal projects, but isn’t there a way to do it with buttons instead of the mouse?
Reygreisin | 2022-05-26 03:01
Yes, just change the _input function to listen for those buttons instead of the mouse.

Friend it shows that you have knowledge and your code is good, I do not understand it at all, honestly it did not work for me and I made many mistakes when implementing it in my game, apart from changing the mouse function to key, nothing worked, anyway, thanks . It’s too complicated for my knowledge.
