所以这里是将提示考虑在内后的代码。 地图不断被重新绘制，keylistener已经改变，但似乎仍然存在问题。字符不能再移动
问题再次出现，左上角的小方块不会移动，这是期望的结果。

呃我的格式不好，我很抱歉。 –
寻求调试帮助的问题（“为什么不是这个代码工作？”）真的应该包括所需的行为，以及*在问题本身*中重现*所需的最短代码。请创建并发布您的[mcve]，以便我们可以使用一个小型可编译和可运行的程序，以便我们可以自己测试您的代码，并希望对其进行修改以使其可以正常工作。请注意，我们不希望看到您的整个程序**，也不应该发布指向代码库的链接。相反，保持它小，保持简单，并使其运作。运气。 –
我也会帮忙解释一下当你尝试运行你的创作时发生了什么。例外？还是不按预期工作？ – strash
