Bow and Arrow in UE4

A bow and arrow mechanic prototype that I recently added some touches to. When the arrow is spawned in as the bow is drawn, a force multiplier steadily goes up until it hits 100% - at this point the bow is fully drawn, and the arrow stops moving backwards to indicate to the player that the bowstring is all the way back. I messed with the collision checks and made the arrow stop simulating physics when it hits the circular target, in effect freezing the arrow where it is when the overlap is detected.
