DESCRIPTION
In this tutorial we will be creating a locked door with a physical lock on it. This must be hit/broken in order to unlock and open the door.
CONSTRUCTION
1) Open the Hammer editor programme and create a basic room.
2) Create a prop_dynamic and name it doorgate01, give it the world model models/props_wasteland/exterior_fence003b.mdl.

5) Move the pivot point of the door (looks like a white circle in 2d. blue ball in 3d view) to the side of the door, This is where it will pivot.
I have my door handle on the right, so the pivot should go on the left.
6) Now select the doorgate01 (gate model) and parent it to the doorgate01_pivot01 (nodraw door)
7) Now create another prop_physics and name this doorgate01_lock01 and give it the world model models/props_wasteland/prison_padlock001a.mdl. Place it in a good position. Turn on the flags 'motion disabled' 'prevent pickup' and 'prevent motion on player bump'.
8) With the lock still selected, goto the outputs and add the following:
