Hello there, I really need some help 'cause I’m tired of this cast. Usually, when a cast doesn’t work, I always find an alternative. But this time, I tried to do a cast with another ActorBP and this cast always fails. I don’t know what to do… Could someone help me ? ---

What it means is the thing you’re casting is not of the type you’re trying to cast to. Can I see the code? ---

Ok, sorry missed the picture. Ok, so something overlaps. You check if it’s an UnbreakableVolumeBP. If it is fine, if it’s not, you check if it’s a caisseBP. If it is, the off to the right, otherwise: It’s neither of these things. You have the code right, it’s just the thing that’s overlapping isn’t either of those things you’re checking. Does that make sense? ---

It means something is overlapping with the volumne which is neither of these things. Which gives you two questions: 1. Does it matter? ( sometimes you’re only interested in some things ) 2. What else could be causing the overlap? Actually #2 is what we cast on overlap in the first place. If you’ve got an overlap volume that operates a door for your player, you don’t want the door opening every time a bullet flies past. That’s why we cast and check it actually is our player walking into the volume. ---
