I know in theory this can be done through events, and I like events and all, BUT it's obviously more efficient system-wise to use a script. Basically, how I'd like it to be is be is like a bar system, except heart graphics are overlaid the bar, and an alpha mask is used to hide the bar that isn't below the hearts. The heart amount will be a static value while the HP will be variable, much like any other game. Thanks to anyone that can do this for me!
