0.14 was the big "build anywhere" update and 0.15 fixed a few things. 0.16 is the follow-up where I make it actually feel solid. Letting players place buildings freely opened up a bunch of edge cases — most of this version was hunting those down so the system just works no matter what you throw at it.
A few things from 0.14 and 0.15 needed fixing first. Some machines wouldn't place at all, which turned out to be the floor check only looking at the exact spot under your cursor — but a lot of floors are tagged on the parent object rather than the collider, so the game would look right at a perfectly good floor and call it invalid. It now checks the whole object, so valid floors read as valid.
The placement preview also had a habit of flashing at the building's old position for a moment before snapping to your cursor. It now stays hidden until it actually locks onto a surface, so it simply appears where you're looking. While I was at it, buildings that used to hover slightly above the ground now settle flush onto it, and the stairs — which were far more of a fight to get around than they had any right to be — have been sorted out, so moving between levels is smooth again.
The bigger theme this version was making sure that while you're positioning a building or machine, you can't do anything else. Before, you could, and some of it broke the game spectacularly. The worst offender let you walk up and enter the carriage while it was still a ghost following your cursor, which handed control to a vehicle that was mid-placement — a massive bug. Placement now fully locks out everything else. The car, the carriage, the throne, the stockpile, every slave machine, the phone booth, the phone itself, and the map all ignore your input until you confirm or cancel. The world holds still while you build.
The carriage got a little extra attention too. It can now be placed anywhere, like a building, instead of being stuck to floors — it's a vehicle, it belongs outside. I also made sure its "Change Outfit" prompt stops popping up while you're repositioning it.
