How do I run a loop once for each instance?

The problem: I can't realize how to create strictly two instances of laser beam FOR EACH enemy_top. Enemy tops are filtered by instance variable "shock", then each of them must create two beams. It would seem simple, but... The code:

This is one of the code variations that doesn't work as expected.

The top condition is technically a for each you don't need to embed another for each inside it.

Use boolean instead of trigger once. So the logic is when a boolean switched state the action won't executed further more.

How do you see it in the context of my screenshot above?

Using a boolean in place of a trigger once condition does not resolve the problem, the issue is that you are trying to trigger once inside a loop that is running every tick. The fix is to split it into two events because one needs to run every tick and one doesn't. But again this is just repeating my last post.

...you want it to create just 2 beams only. The question is when?..

So, I have a few enemies on layout. They can shoot when they see the player (instance boolean "is shooting"), so when some of the enemies "is shooting" and their weapon is "shock" - they spawn two beams (each of enemy who shoot with "shock").

So there is a condition at 105 that enemy has LOS in that event which you've decided to cut off in the screenshot?

No, all the events for this effect is under [if weapon = "shock"], event 105 is for another weapon. However I already solved the problem by creating these two beams [on "enemy spawn" function] and then set it invisible with width zero. Then when the enemy fires, I take further action.

Thank you guys for your answers anyway!😄
