You should make a blood affect every time the character collides with the stairs.  how to? Add the tag #stairs. really you can add any tag with any name I just recommended calling at stairs. Then create empty blue print go to Texture And make a red circle or any type of blood or something. Then what do you want to do make sure it’s not solid and has no collider’s. No add a code to the character when collides with #stairs Create actor from blue print and choose the blood affect. And you should be good! Good game by the way
