Rigidbody2D Reduce Jump Speed

Reduce a Rigidbody2D's vertical speed if the jump button is released early. This tweak allows higher jumps if the player holds the jump button down.

Parameter	Description
Rigidbody	The Rigidbody to control.
Is Jumping	Set to true while the jump button is pressed. Generally set by an input action like InputGetButton.
Multiplier	The amount of speed to lose when releasing the jump button while the rigidbody is still going up. This is a multiplier, so 0.5 loses 50% of the speed.

Usages
