So I need a way to make it so that when someone gets below 3 hearts, they will get launched into the air and when they come back down they wont take any fall damage. I have gotten the health check thing but the launching into air and no fall damage thing I haven't gotten that down. Also with the no falldamage, after they hit the ground they need to be able to take fall damage again, so no fall damage just for when they get launched into the air. Please Help. If you need more explanation then I will try.
