我正在做一个pygame游戏,我希望我的敌人跟随玩家并预测它的路径。我不只是想缩短玩家和敌人之间的距离。敌人的数量将根据等级而定,每3级将增加一个新的敌人。我附上了我的全部代码和一个截图,显示我的敌人目前只是在直线移动

为此,您需要一些向量数学,因此我建议重新构造代码并学习如何使用^{} ;你可以找到一个例子here
要找到你问题的答案(“预测路径”),你可以在谷歌上搜索
intercept vector
或pursuit vector
。这将产生一些结果,例如How to calculate the vector of an interception?或Calculating Intercepting Vector例如,我翻译了第二个问题的最后一个答案,并将其复制/粘贴到我的answers中,因为a)我太懒了,无法再次编写所有内容;b)只有一点代码需要更改才能实现拦截逻辑(类
