To begin, let me clarify this:
Fall damage is environmental damage inflicted upon a player when he falls from a certain height.
In other words, when my players falls from a certain height, I need the player to take damage. I've thought about many different ways to approach this, but none of my approaches worked correctly. If it helps, I have a property that displays velocity, it uses the following:
getLinearVelocity().length. Also, I have an object which is above all the floors in my scene. It has the property "floor" to identify it.
How would I approach creating fall damage?
