Hi! In this tutorial I'll cover how to make your characters flash red when they're damaged in Game Maker Studio 2.3 . We'll use animation curves to control the flash animation (including an example of how to do this in Game Maker Studio 2.3.2). Additionally I'll extend this to show you how to add more color channels, and use animation curves to animation generic colors. I wasn't sure where to go with today animation principle, so instead I'm recommending Arend Peter Kraus's channel (because he has a great name ;) )
