我正在为一个Unity平台游戏的敌人AI运动系统工作，这将允许敌人在一个固定的基础上作出三个决定之一：空闲，向右移动，或移动到剩下。我希望敌人能够选择任何这些决策，即使它刚刚挑选出的决策将与其下一个决策相同（即它可以连续选择“向右移动”两次，也可以选择多次希望）。下面的脚本没有错误，但是当我测试游戏时，它会导致我的敌人口吃。有时候，它会立即向右移动，然后向左移动等等。我觉得我的代码的内在逻辑有点正确，但实现它的方式需要一些工作。我很感激你能给我的任何帮助。顺便说一句，如果我将“MakeMovementDecision”功能放在“开始”功能中，敌人会向左或向右移动.07，或者静止不动，并且从不执行另一个移动功能。敌方人工智能运动决策

你为什么调用FixedUpdate（您MakeMovementDecision），并在自己的决定？尝试删除'FixedUpdate（）'并将'MakeMovementDecision（）'函数放在'Start（）'里面...... – 0014
是的，我试过了（我编辑了我的原始文章以包含关于此的注释）。它只是向左或向右移动敌人0.07个单位，或者选择“空闲”变体，但是敌人再也不会移动。在检查员看不到x值的情况下，根本无法察觉到敌人正在移动。 – Dalsia
