Color tween not working properly

[indicidian]

I’m trying to make an outline around a sprite change from yellow to red to telegraph when an enemy is about to fire

i have a tween set up do if the effect is enabled the line gets thicker and turns red. the problem is that while the thickness property works fine, if I dont have a trigger once condition, the color tween resets every frame and doesnt change, but when i have a trigger once condition, only one of the enemies shows the effect. I’m not sure how to fix this

In that last event, where you check if the effect is enabled, also add a condition that checks if the effect has finished playing.

thank you, I knew it had to be something really obvious i was overlooking
