我正在制作一款需要敌人遵循方法的游戏。现在的问题是它似乎不想进入“慢”的状态。国家，因此不会去下一个航路点。我认为这可能与“等待时间”有关。但我不太确定这是不是问题所在。敌人也没有任何明确的理由向上移动。我使用的脚本是从Javascript转换而来的，所以问题可能源于此问题。
我知道这是一个很大的问题，但我已经试图解决这个问题好几天（甚至一周）而没有任何成功。任何帮助将不胜感激。

// Converted from UnityScript to C# at http://www.M2H.nl/files/js_to_c.php - by Mike Hergaarden
// Do test the code! You usually need to change a few small bits. // This is a very simple waypoint system.
// Each bit is explained in as much detail as possible for people (like me!) who need every single line explained.
//
// As a side note to the inexperienced (like me at the moment!), you can delete the word "public" on any variable to see it in the inspector for debugging.
//
// I am sure there are issues with this as is, but it seems to work pretty well as a demonstration.
//
//STEPS:
//1. Attach this script to a GameObject with a RidgidBody and a Collider.
//2. Change the "Size" variable in "Waypoints" to the number of waypoints you want to use.
//3. Drop your waypoint objects on to the empty variable slots.
//4. Make sure all your waypoint objects have colliders. (Sphere Collider is best IMO).
//5. Click the checkbox for "is Trigger" to "On" on the waypoint objects to make them triggers.
//6. Set the Size (radius for sphere collider) or just Scale for your waypoints.
//7. Have fun! Try changing variables to get different speeds and such.
//
// Disclaimer:
// Extreeme values will start to mess things up.
// Maybe someone more experienced than me knows how to improve it.
// Please correct me if any of my comments are incorrect.
