I dont know whats false

You must be more specific in what doesn't work if you are going to get any help with this.

yo ok it completely dont works. I have casted the spell and nothing transpires it should create a nova

Make the spell display text in the game at some specific actions so you know how much that works. I always do that. Set some text after the variables has been defined so you know that the script works so far and some text in the loop telling what happens. This will help you figure out what part is wrong.
