Help with wad. GZDoom Builder.

I'm making a wad where you play through the Citadel from System Shock. The only problem I've had so far in recreating the Citadel is with doors. In System Shock doors are basically a wall that animates to be open. I don't know how I can recreate this in doom. In this video you can see an example of what I mean. Is there any way I can do this in doom? Thanks in advance.

Possibly through animated textures and some ACS scripting, but if you want the door to have actual "thickness" you'd want PolyObjects. 

If you're targeting GZDoom you could try out https://zdoom.org/wiki/Animated_door

Thanks guys it worked flawlessly. Back to mapping for me.
