get_transform is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead.

这个问题的出现，千万不能出现，出现就说明你的代码质量不够高，stupidcode man!!! or girl…

第一种：

Error code:private Transform mainCameraTr = Camera.main.transform;Right Code:private Transform mainCameraTr ;void Start(){    mainCameraTr = Camera.main.transform;}

第二种：

public class RotateAroundSelf : MonoBehaviour {     public RotateAroundSelf(float foo)  // Class class constructor     {         Vector3 speed = new Vector3(0,foo,0); //now it's evil     } }
