How do I stop objects spawning after a set amount of time

Ok so this isn't really a big deal but when I switch to my plasma gun I have it set up so after 10 shots the bullets are destroyed every tick for 8 seconds. This is a problem because if you spam the gun 10 times then it will delete all the bullets in the layout including the ones still in the air. I want it so after 10 shots the bullets stop spawning instead of just getting destroyed every tick.

Here is my file if you want to take a look

One of the ways to do it:

Add boolean instance variable to the gun, let's name it "cooldown"

and another number global variable, let's name it "Shoots"

Keyboard on Space pressed ---- Gun Spawn bullets - and add 1 to global variable

Gun Cooldown is True

System global variable = 8 ------ Set cooldown to false - wait 5 seconds - Set cooldown to true - Set global variable to 0

System trigger once

can you explain a little better. Im sorry but my nooby brain didn't really understand

He means something like this image I have in my dropbox:

This blocks a key from being pressed for 3 seconds after it's first pressed. If you do the same with your spawn, it can only spawn ever so many seconds, preventing too many from existing at the same time.
