Okay I got a little ambitious and started building a huge mansion at 15 Summer Hill court in Sunset Valley (The 60X60 lot in the rich area) and after designing and furnishing the plethora of gust rooms I thought any good mansion should have I thought, "These are starting to look more like luxury suites in a fancy hotel." so then I thought "I might as well make this into an apartment building but I'm having some trouble.
Reading this thread I saw that in build mode you Shift-Click or Shift-Control-Click n a door to a unit to mark it as an NPC door but do so before placing any room markers.
Well, I had already placed public room markers but not the private ones so I deleted the public room markers and then saved a copy of the house to the library and then started a new game and placed the building on the lot in the new game with no markers and if I shift click on a door it just grabs the door and if I Control-Shift-Click on it the options I get are (Lock, Delete it, Reset, Clone, Add the ability to add triggers and activated behaviors)
Tesingcheatsenabled is on
buydebug is on
restrictbuildbuyinbuildings is off
What else do I need to do to be able to set the doors to the other units as NPC doors?
Might the fact that I already furnished these units be a problem? That was before I found out what a waste of time that is. The furnished price for this lot is currently 1.3 million.
