Hey 
lionz
Really helpful of you thanks so much.
The first thing I didn't understand was that I thought it was only possible to input numbers in the every x seconds event.
But you showed me correctly :D
But then I run in to another problem.
Idk why but even though I set the "firerate" to 1.0,2.0&3.0 the fireballs spawn at 0.1 per second
XD
aslo here is the events I used,it's the same I think
