Im making a game where the play can hold the mouse down to keep firing their weapon but holding this down causes a single script to run multiple times at once causing the player to shoot two bullets together instead of one and I can't fix it

The trouble is that the original Pew is generating clones, but so are each of the clones.
Two solutions I can think of:
Option 1. Give Pew a For This Sprite Only variable, “IsClone?”

when green flag clicked
set  (IsClone?) to [No]

when I start as a clone
set  (IsClone?) to [Yes]

Then wrap your clone script in

if <(IsClone?)  = [No]> then
create clone of [myself v]
end

Option 2. Have a different sprite create the clones of Pew. Sprite2 is a good candidate.

Yay! it worked thank you so much!

Happy to help!
