Timers, why is it blinking?

I want to create a laser on every 0.3 sec and to be (laser) deleted in 0.1
a laser is created on 0.3 sec but then it starts blinking in 0.1 rhythm
I get same results with - Reset the timer “1laserL1” of laser

Remove that “all of those conditions are true” (and) condition, it may only cause problems and should only ever be used inside of or conditions. I am not sure if it applies to the and event too but the or event is messing with object selection, which is important in your case as you use an object timer.
