PlayerMoveInput

Remarks

MoveIntent, quantized. The two are deliberately separate types and not one: MoveIntent is a component in Vixen.Engine, which may not reference Vixen.Net at all, and a component that had to implement a networking interface would drag the whole of it into every game that has a player and no server.

Small is the whole point. InputLog`1 sends the newest input and the few before it, every tick, so this is the one payload that goes out more often than a snapshot. Fifty-two bits: two axes at eight, two angles at ten, and the buttons whole.

The quantization is not a loss the prediction has to tolerate — it is what makes the prediction agree. The client sends this, the server decodes it, and both then run the same movement rules over the same decoded numbers. A client that predicted with its full-precision intent and sent a rounded one would mispredict by the rounding on every single tick, on a perfect connection, and it would look like jitter. Round is what a client applies to its own intent to stay in step.
