【问题描述】：
我正在为一个业务问题进行模拟，但我正在尝试构建一个 2d 游戏来演示模拟的动作。
为此，我从一个实际的 Python 游戏开始，我在网上找到了一些代码。
目标是通过随机整数创建 100 次模拟运动（上、下、左、右、停止）。比如random = 1，然后左移。
由于某种原因，我能够发送第一个动作，但游戏忽略了第二个到第 100 个动作。
有人可以告诉我我做错了什么吗？
我将非常感谢某人的专业知识。

【问题讨论】：
-
direction怎么了？您将其设置为空字符串，这在方法movePlayer中没有任何影响，您不会将其重新分配给任何东西，但您每次都打印它。 -
@Reti43 感谢捕获 - 我删除了它，但我仍然得到相同的结果。
-
我并不感到惊讶，因为它不应该对程序产生任何影响。我只是问你是否打算让它产生一些效果。你能解释一下
self.schedule(self.update)这行吗？这对我来说没有意义。 -
检查每一帧的冲突
-
好吧，我看到你所做的只是一个循环，你选择一个方向 100 次，然后将该参数发送到
movePlayer()方法，它只会更新你的速度向量。除非玩家的位置在你改变他的速度时自动更新，否则我在这里看不到任何“运动”。
