Hold down button to repeatedly adding objects?

I’ve got a plane for a scrolling shooter set up to fire bullets with the space bar. Using empties, I got it firing sets of two bullets. The only problem is it only does it once when the space bar is pressed down so it would have to be pressed more than once. Any way to set it up so holding down the space bar rapidly adds them like a machine gun?

Need to turn on the true pulse button. Looks like … On the keyboard sensor. Then you can chose the pulse rate in number of ticks before a single true pulse. Hope that helps.

Yeah, Loyhogg is right. By enabling true pulse you can choose how often you want your bullet to be fired. If you want one a second, change the pulse to 60, 2 a second would be 30 etc.
