tags: tip—
强化学习训练把dino run玩到4000分，教程链接，需要云服务器，所以放弃了。
在网上找到了外挂的方法：https://blog.csdn.net/weixin_41474364/article/details/85613923
根据判断X轴方向小恐龙和前面物品距离进行自动跳跃，添加了代码避免小恐龙跳过蛋糕、避而不吃，调整了对障碍物需要跳跃的高度判断，防止小恐龙看到低飞的鸟儿迎面而上，还有能够在代码执行后，自动开始游戏。

将代码复制到console，回车，会自动进行跳跃，获取分数的速度依然和正常游玩的玩家是一样的，小恐龙走一步记一分。
下面的方法，可以在短时间内迅速加分：

window.tempGameOver = Runner.instance_.gameOver;
Runner.instance_.gameOver = function(){}
