One-Way-Doors / Secret Doors

[sajon]

I have recently been thinking about how to make a one-way door / secret door.
Does any one have any ideas on how this would be done?

When I think about secret doors I imagine the following ones:

- a closet that swings open like a door
- a revolving wall
- a transparent mirror
- a chimney with an illusion wall behind it
- a caved in passage with rocks that can be removed to open a small opening to enter and afterwards caved further in
- an illusionary bush hiding an entrance
- dream world entrance (John's ORRR1 room)
- bricks in walls turning and moving side ways (saw it in a Potter movie once)

I just wonder if these can be made possible. Can you link a normal door with wall graphics, so sliding doors become sliding walls?

Doors in Grimrock have special "animation" and collision handling based on the "gate" node in the model. This is why there aren't any .animation files for standard doors opening/closing, and why you can throw a rock through a partly-closed door. The only forms of this "animation" supported for doors are moving up/down (most doors) and moving sideways (iron double door in Grimrock 1). So if you want a "door" with more complicated animation, you make normal animations and add code to enable/disable the DoorComponent as it closes/opens. See the definition of beach_master_gate for an example.
