I have a sword attached to a model who swings it every time the mouse is clicked. I would like to know if there is a way the sword could slice though things when it hits them. Is there a way i could limit this to certain objects? That way he wouldn't cut though solid steel.
You could have the game engine replace the "solid" model with a model representing the "broken" model. Not the best method for realism, but it would work every time :)
