How do I add delay

Hi, Im making a game for touche screen but I cant figure out how im gona do the “fire” button work
when im putting my mouse over the button it just reapeats shoting without any delay.

I know I can ad so I have to press a key but on mobile there is no key so that doesent work (:

In the event that creates the bullet (I suspect it’ll be something like Mouse over fireButton), add a trigger once condition.

I tryed it and it works, ty so much(:blush:
