Which way is right

Written while this is still in the working tree. None of it is on the live site yet: it is here because the work is done and being tested, not because it has shipped.

Playtesters said the mouse was inverted. It was. So was dragging a finger across the screen, and the right stick on a game controller, and the steering arc on the phone deck. Push right, turn left, on all four.

Headings in here grow to the left. That is an arbitrary decision taken early, it is not wrong, and it only has to be obeyed: to turn right, the number has to get smaller. All four inputs were making it bigger.

It survived because looking around is not something you do in a car. You steer, and the chase camera puts the view back behind the car every frame regardless of what you asked for. On the first of September the four village captures started opening on foot, where looking around is the only thing you do, and it took about a day for someone to say so.

The fix is not the sign. The fix is that there is one piece of maths now instead of four copies of it, with a test that fails if the handedness ever flips back. Four copies is four chances to get it wrong and one chance in four of noticing when you do.

The part worth writing down is the same thing the roofs post was about last week. This error is still live in two other places. The acro quad works out which way is right the same way, so its yaw and its roll are both flipped, and nobody has complained because nobody has flown it yet. Photo mode takes you downward when you look up and hold forward. Both are written down and neither is fixed, and saying so in public is the only thing I have found that reliably sends me back.
