Hi everyone,
Finally I achieve to make my first UE4 game 
My game is a single room that with a pressure plate, when you step plate the door opens, but running you can’t escape from the room (like the course) but in my game you’ll have a phantom pawn that will reproduce your lasts movements (it comes with a countdown) so, you have to go to the plate, wait a few seconds and then go to the door, wait until the phantom step inside the plate and he will free you
I let you a video and my github with the source 
and my github https://github.com/pardovimes
