Flashing Colored Light

As the title says im wondering if there was an easy way to make the room/layout flash red. Not like a quick flash, but like in the movies a base is under sever lock down lights are mostly out and like warning lights pulsate.

Anyways thanks for any insight on this in advance.

I haven't tried this but I would create a rectangular sprite that is red and that covers the whole screen. I would then set the Opacity to oscillate from 100 (red) to 0 (completely transparent) using the SINE behavior.

Try like farmerdwight said with the EaseTween behavior

Or you can use existing shaders for the layout/layer.

Either a rectangle, a shader (would be more performance-demanding), or create a layer with transparency and a background color set. You would need to set transparent to No and then adjust the opacity. It may be neat to apply a shader to that layer, too.

Wow thankyou for all the ideas, Ill give them all a try and see what does better on resources
