So I've been poking at the placement flags on various occasions now, here's what I learned by now:

This is one entry labeled "PlacementFlags" in the COBJ, I've only seen the last four digits being used so far.

• 0x00001000 -- multi-placement (i.e. when selecting this object, the game will automatically keep it selected until the user picks something else); e.g. in counters, curtains
• 0x00000100 -- will stay up when the wall drops (for wall attachments), e.g. mirrors (and the no-drop cabinets I made)
• 0x00000002 -- fixed height (for wall attachments), e.g. mirrors
• 0x00000006 -- variable height (for wall attachments), e.g. windowboxes, wall lights
• 0x00000008 -- ceiling lights (I guess it means: stick this to the ceiling)
• 0x0000000E -- not sure; used in cabinets .. maybe it means something like "glued to walls OR ceilings"

Which slots an object will use depends on Unk03, not the placement flag (0x01 = small (shelves), 0x02 = medium (e.g. on side tables), 0x03 = large (e.g. on end tables)).


Any other insights? Ah OK, very good -- coincidentially I just came across the following list in the buy/build scripts (these are decimal, obviously):




So that would be the complete info.
