对象被破坏了……顺便问一下，如果每个元素的值相同，那么为什么要存储每个航路点的所有值？@derHugo在我使用实例化对象的SphereBuilder脚本时是这样的。所以现在我不使用它，只使用created 4个立方体并将它们标记为目标，现在它们没有被破坏和丢失。但是相机只移动到第一个立方体，而没有继续移动到其他立方体。（这就是为什么我还删除了问题中的屏幕截图，因为丢失的破坏问题与此无关）@derHugo现在它们有相同的值，但当我使用我的脚本SphereBuilder或其他实例化脚本时，我发现它实例化了具有随机位置、旋转和缩放的对象。我发现了诸如desiredHeight
flightSmoothTime
等值。问题出在我的集合上脚本检查器中的Ting会飞到地形上。可变的所需高度设置为10，但立方体的高度为0。一旦将所需高度更改为0，或者将立方体高度更改为更高，则效果会非常理想。
