In part 7 of my Unreal Engine 5 endless runner series, I build a proper character death system so the game actually ends when you collide with obstacles. I start inside my Base Obstacle BP by using a Death Box overlap, then I make sure the overlapped actor is the Player Character before triggering death. Instead of casting (which is a bit expensive), I switch the communication to a Blueprint Interface so I can call the Death event anywhere without a hard reference. Inside the character, I implement the death logic: I set the mesh collision profile to Ragdoll at runtime, enable Simulate Physics for that ragdoll effect, then disable Character Movement and player input so the character can’t keep moving after dying. I also show the important setup step—creating and assigning a Physics Asset—otherwise the ragdoll won’t work. After that, I fix a common endless runner issue: the “must roll” obstacle. I add a Must Roll boolean on the obstacle, then I avoid the unreliable Is Rolling boolean by using montage notifies (Roll Start / Roll End) to drive a “rolled enough” boolean. If you’re rolled enough, I temporarily disable obstacle collision so you can pass; if not, you die. Finally, I adjust obstacle collision to overlap cameras to prevent camera clipping during jumps and rolls.
