I am kind of new to unreal engine 4, and right now I am making a horror game. I have a lot of the map done, and I have flashlights, and stuff like that. Iām not sure how to do a jumpscare though. I want it to be when I go into a room, or I trigger something, something will pop out and start screaming at you. If you could help, that would be great, thanks 
You could do it with matinee ā just add a trigger - open the level bp and add a reference to the trigger - create a new matinee sequence (move, animate, add sound to the character) - connect the trigger with the play from the matinee ā now when the player touches the trigger, the matinee will play.
