Issue on Spawn Object's Imagepoint

I have 10 imagepoints on the enemy (not including origin point) and I want to spawn a spark on a random imagepoint number from 1-10

So I use an event like this

Enemy on collision with player

For Each Enemy

-> Enemy spawns spark at layer 0 at imagepoint choose(1,2,3,4,5,6,7,8,9,10)

but it spawns 10 sparks at the same time

I tried this

-> Enemy spawns spark at layer 0 at imagepoint floor(random(10))+1

but it spawns 10 sparks the same.

Is it not possible to use expressions (system expressions, that is) for imagepoint?

Have you tried adding the "trigger once while true" condition after yours?

For example:

(enemy.X > 10 && Trigger once while true) ->Enemy spawns spark at layer 0 at imagepoint choose(1,2,3,4,5,6,7,8,9,10)

I can't use "trigger once while true" because on collision is a trigger condition.

I did try "trigger once while true" as a sub-event condition. I don't know why it still spawns 10 spark objects.

I also tried adding (3rd level) sub-events under "trigger once while true" event like these:

choose(1,2,3,4,5,6,7,8,9,10) = 1

--> spawn at imagepoint 1

choose(1,2,3,4,5,6,7,8,9,10) = 2

--> spawn at imagepoint 2

and so on

still spawning 10 sparks

You yourself mention having a "For each enemy" - this shouldn't be needed as on collision they are already picked. Also I'd use random(1,10) for the imagepoint choice.

you could do it like so
