KeyboardInput

Tracks keyboard state frame-by-frame so you can poll inputs in your loop.

Examples

const keyboard = new KeyboardInput();
 
function tick() {
  if (keyboard.isDown("ArrowLeft")) moveLeft();
  if (keyboard.wasPressed("Space")) jump();
  keyboard.update();
  requestAnimationFrame(tick);
}
