so i have a HL2DM map and i notice certain props can only be picked up with the grav gun as long as the entity tied to the prop is the prop_physics entity as opposed to the prop_physics_multiplayer entity. Should I worry about using prop_physics entities in my multiplayer map? What the hell is the difference between the prop_physics and prop_physics_multiplayer entites anyways? Just curious so I dont end up screwin myself in the longrun by usin an entity i shouldnt use.
