I would like to design a game where the actor changes its color and once it hits by another color it dies. I did most of that, but the actor still dies if it hits the other color even if it's still in the original color. I used start-if collide with new color- set actor color to new color Now I need a way to make the actor dies only after its color changed to the opposite color. Is there a way I can add collide boolean after set color?
