I encountered a specific issue. I don't think that it's really that complex, but since the stress from school i can't figure it out on my own. So i need your help.
The problem is, i want on the start of the level the screen to flash with red color, and soon to come back to the normal color pattern (like an alarm).
I figured it out to use another layer with red color on top of the original level, and just change the opacity but... how can i make the "alarm effect" (the flashing red color) to loop through the level?
