//首先要在场景中放入一辆汽车模型，并给模型加上一个标签，叫：“车”
//本教程注释挺多，你别说你看不懂。
for (const e of world.querySelectorAll('.车')) {//遍历所有实体
    e.collides = true //让车模型开启碰撞
    e.fixed = true //使车模型固定实体不被推移
    e.onEntityContact(async ({ other }) => { //每当车碰到另一个实体
        if (other.isPlayer) { //如果另一个实体是玩家
            other.mesh = e.mesh;
            other.meshScale = e.meshScale;
            other.meshOrientation = e.meshOrientation.rotateY(Math.PI/0.5);// 调整mesh方向, 旋转180度，你可以根据你的运行结果调整此代码。
            other.player.invisible = true; // 隐藏玩家模型（敞篷车不用隐藏）
            // 设置速度：
            other.player.walkSpeed = 0.8;
            other.player.walkAcceleration = 0.05;
            other.player.runSpeed = 2.2;

        }
    })
