[Noob needs help] Could someone explain the process of how to do doors?

[GraphicsKid]

Then place a wall through the door way so it's blocked? Don't think so. I asked how I can place the door without the wall actually going into the doorway and how to place it correctly etc.

How about you snap at him again? That will make everyone want to help you!

Now you DO NOT place a WALL for a DOORWAY. Use "Door Frame" and "Door Way". These are both "static objects" then the door you put inside it is an "entity". You'll want the door to be slightly closer to the side it opens out towards otherwise the door frame itself is going to be hitting the door and preventing it from opening all the way.
