You also got to check the angle between the player's eyes and the surface's normal among other things. Once you grabbed the ledge you can hook your movement code into PlayerMove(). I can't tell if it's the best way to do it but it works. It might also requires some work with animations and prediction. -- Mandibull _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
