Something frictional games should do in next games.

Well technically he probably could do it through the level editor buuuttt....

That would be extremely time consuming to do it with each door, create a lot of headaches, probably be really buggy, and just plain inefficient.

Its possibly he has a slight grasp on coding, its probably just a slight one though. Like making mods for a game engine/toolset/leveleditor/etc with very limited freedom on what you can/can't do.
