Momentum transfer

Momentum transfer is the general action of imparting a velocity change upon a target via a projectile. All projectiles have the momentumtransfer variable. Projectiles with a higher momentumtransfer impart larger amounts of their velocity to struck targets.

Many servers on Unreal prevent against players being able to move other players via momentumtransfer, checking if the shooter and target are both playerpawns and zeroing out the momentum of any takedamage events.
