团结拼搏更像泰山

Question

我正在努力使抓钩更流畅，但目前为止，它非常颠簸，没有正确的感觉。它当前会排成一条线，并将玩家拉到那里。我还没有尝试任何东西，因为我甚至不确定我们是否要开始修复这个问题。下面是所有抓斗代码`使用系统。收藏；使用System.Collections。通用的使用UnityEngine；

尝试使用FixedUpdate代替Update来进行基于物理的工作（基本上现在更新中的所有代码）。更新取决于计算机的时钟速度和刷新率（或多或少），并以相当不规则的间隔被调用，因为在当前帧完成处理后，下一帧将调用下一个更新FixedUpdate使其与帧速率无关。

此外，您可以使用< code > application . target frame rate 来限制您的帧速率，并将其限制为一个不错的FPS。

您也可以将您的运动与Time.deltaTime相乘以获得更平滑的运动，尽管这是一种标准做法，但作为平滑值使用仍有争议。
