void displayGameOver() {

  textSize(32);
  textAlign(CENTER, CENTER);
  text("遊戲結束！", width / 2, height / 2 - 20);
  textSize(16);
  text("按一下回到主畫面", width / 2, height / 2 + 20);
}

void displayStepCount() {
  fill(0);
  textSize(16);
  textAlign(LEFT);
  text("步數：" + stepCount, 10, height - 10);  // 顯示步數
}

void keyPressed() {
  if (keyCode == UP && ballY > 0 && !grid[ballX][ballY - 1]) {
    ballY--;
    stepCount++;
  } else if (keyCode == DOWN && ballY < rows - 1 && !grid[ballX][ballY + 1]) {
    ballY++;
    stepCount++;
  } else if (keyCode == LEFT && ballX > 0 && !grid[ballX - 1][ballY]) {
    ballX--;
    stepCount++;
  } else if (keyCode == RIGHT && ballX < cols - 1 && !grid[ballX + 1][ballY]) {
    ballX++;
    stepCount++;
    if (stepCount >= maxSteps) {
      gamestopGame();
