Theyre both trigger colliders that do things related to damage if that's what youre asking. But I think the distinction between "Hurtboxes are the damage triggers acted upon by the damage system" and "Hitboxes are the damage triggers that cause action within the damage system" is useful granularity.

Yeah, I was thinking in terms of how a game engine would implement them. The distinction of what they do would be probably handled in the callback of the user, but for the engine they’re both just triggers that call into some code. Or do they have any more differences?
