It doesn't? Interesting. Can you show us the code under the when I receive shoot projectile block?

If it's too much to type here, you can share the project and give the link instead.

Because of the ,Wait (0.2), seconds block.

That code wouldn't work as clones receive messages so you are telling the clones + main sprite to create a clone of themself so: 1,2,4,8,16,32,64,128,256. and we'll have reached the clone limit next shoot.

I see the issue. You need to remove the “wait 0.2 seconds” block. The “key pressed” check is only happening once every 0.2 seconds. Which means, sometimes you have to hold down space for 0.2 seconds to spawn a clone:

when gf clicked
forever
next costume
-wait (0.2) secs
if <key [space v] pressed?> then
broadcast (shoot projectile v)
end
end

Here, I would recommend you replace this code, with this:

when I start as a clone
repeat until <touching (edge v)?>
move (10) steps
end
+delete this clone

The forever loop is unnecessary - once the condition “is touching edge?” is met, the repeat until loop will be “dead”. The forever loop would not do anything.

I added the “delete this clone” block, because Scratch has a limit of 300 clones. This means, after you shot 300 projectiles, without this block, your project would stop shooting ANY projectiles, at all.
