I need some help, How does the Button script work? i seem to be unable to get mine to work.

You need to load an image first with "image" command. Then you use this image's name (that you set it to) in "button" command. The image should be a horizontal sprites-sheet consisting of three uniform images

Thank you for the answer. I've known about the image command, but the problem is that when I execute the code, it just freezes the game.
