"Expecting property name enclosed in double quotes" when running agents scene
总而言之，我有一对具有旋转轴点的腿，希望能够让计算机计算出腿应该旋转的方向，以使其自身保持平衡并保持 'waist' game-object 大于一定高度（本质上是self-balancing）。如果腰部低于某个高度，（即，摔倒）代理人将获得奖励减少。当我 运行 Anaconda 提示和 运行 Unity 当它要求我时，Unity 冻结 并且 Anaconda 显示如下所示的错误代码。很难找到最新的教程，所以我非常感谢您的支持。 怎么回事？谢谢。 (:
