Keyboard

Real, running code, on the current Spine transport. A small ebiten (2D game engine) window that captures held keys and publishes a [4][4]float64 delta transform — not a terminal-based key reader. Part of the live keyboard-controller → Kinematic Engine → CrackHead pipeline.

What it actually does

var goal [4][4]float64
goal[0][0], goal[1][1], goal[2][2], goal[3][3] = 1, 1, 1, 1 // identity

if ebiten.IsKeyPressed(ebiten.KeyW) { goal[1][3] += 0.001 }
if ebiten.IsKeyPressed(ebiten.KeyS) { goal[1][3] -= 0.001 }
if ebiten.IsKeyPressed(ebiten.KeyA) { goal[2][3] += 0.001 }
if ebiten.IsKeyPressed(ebiten.KeyD) { goal[2][3] -= 0.001 }

pub.Publish(goal)

W/S/A/D nudge translation components of an identity matrix by a fixed step per frame (Update runs at ebiten's 60 Hz), while held — this is a pure translation delta, no rotation. Escape quits. The window itself renders nothing (Draw is empty) — it exists only to own keyboard focus and run ebiten's input loop.

Connects via spine.CreateNode(*namespace, *key, context.Background(), logger) and spine.NewPublisher[[4][4]float64] (flags: -namespace default "rime", -name default "r1-change", -key default "ppap" — see spine-go).
