Sets the body's vertical drag.
Drag can be considered as a form of deceleration that will return the velocity of a body back to zero over time. It is the absolute loss of velocity due to movement, in pixels per second squared. The x and y components are applied separately.
useDamping is true, this is 1 minus the damping factor.
A value of 1 means the Body loses no velocity.
A value of 0.95 means the Body loses 5% of its velocity per step.
A value of 0.5 means the Body loses 50% of its velocity per step.
Drag is applied only when
acceleration is zero.
The amount of vertical drag to apply.
