Ok, I suspect your event Hit isn’t firing. There are so many little caveats with it. Try hitting F9 with the delay selected to place a breakpoint and play again, if the blueprint doesn’t pause the game, it’s not firing. Some things to check. The event hit only fires when the root object makes a collision, so if your collision object is the box collision, you need to use OnComponentHit instead. Secondly, make sure you have “generate hit events” enabled on the object you want to collide, it’s off by default. Lastly, make sure your object has valid collision settings.
