6. Autoplay bot

From Auto-play the Chrome Dino Game with JavaScript

(() => {
	const runner = Runner.getInstance();
	if (window.__dinoAutoPlayTimer) {
		clearInterval(window.__dinoAutoPlayTimer);
	}

	const sendKey = (type, code, keyCode) => {

				code,
				keyCode,
				which: keyCode,
				bubbles: true,
				cancelable: true,
			}),
		);
	};

	let lastActionAt = 0;
	let ducking = false;

	window.__dinoAutoPlayTimer = setInterval(() => {
		if (runner.crashed || !runner.playing) return;

		const obstacle = runner.horizon?.obstacles?.[0];
		if (!obstacle) {
			if (ducking) {
				sendKey("keyup", "ArrowDown", 40);
				ducking = false;
			}
			return;
		}

		const canvasHeight = runner.dimensions.HEIGHT || runner.dimensions.height;
		const trexHeight = runner.tRex.config.HEIGHT || runner.tRex.config.height;
		const obstacleHeight = obstacle.typeConfig?.height || 0;
		const obstacleBottom = canvasHeight - obstacle.yPos - obstacleHeight;
		const threshold = 25 * runner.currentSpeed - obstacle.width / 2;

		if (obstacle.xPos >= threshold || Date.now() - lastActionAt < 250) return;

		if (obstacleBottom > trexHeight) return; // High bird: keep running

		if (obstacle.yPos > canvasHeight / 2) {
			if (ducking) {
				sendKey("keyup", "ArrowDown", 40);
				ducking = false;
			}
			sendKey("keydown", "Space", 32);
			sendKey("keyup", "Space", 32);
