In Scratch 1.4 there is no "stop other scripts of this sprite" block. And the "stop other scripts of this sprite" block of Scratch 2.0 stops ALL scripts of a sprite. Thanks to Scratch re-entrancy, we can decide if we want to selectively start or stop a script. Scratch re-entrancy is when you send a message: the scripts that where already running because of the very same message, are rerun from start. So we can selectively start or stop a script by simply setting a variable and checking its value every time that that message is received. The goal in this project is to allow any sprite (or the sprite itself) to stop a running script of another sprite. In this example the cat's script is started and stopped by Sprite2, by sending the "start dancing"/"stop dancing" messages.
