Is it possible in a plugin. Lets say make all of your hearts look like half hearts or make it so when you take damage your hearts go away backwards? Is any of this possible? This isn't exactly what I need hearts to do, but if this works what I need might work.
Making the hearts go backwards would be but would be somewhat complex and you would probably have to start at half a heart. I don't think making them all half hearts would be though as displaying the health is handled client side.
