Hey there @Gastouuu! Welcome back to the community! So it looks like your mantle system is probably overlap based, so it’s entirely circumventing the Hit event until the player jumps again.
Depending on how your character and mantle system is setup, you could also check for overlaps with the character on the obstacle with On Component Overlap. That’d probably be the simplest way, but the immediate side effect would be that if you have large overlaps stemming from the player character, they could trigger the obstacle prematurely.
