Unity FormerlySerializedAs的使用

Posted 2022-09-01 海涛高软

public class shishi : MonoBehaviour

    public CameraSizeHandler CameraSize01;

    [System.Serializable]
    public class CameraSizeHandler
    
        public Color BackgroundColor = Color.gray;
        public Rect ViewPortRect = new Rect(0.0f, 0.0f, 1.0f, 1.0f); 
        public RectOffset ViewPortOffset; 
        public Vector2 CanvasMargin = new Vector2(22.0f, 22.0f);
        public float MaxSpeed = 1000.0f;
        bool enabled = false;

 现在有一个需求，想改一改CameraSize01这个字段的名字，比如想修改为CameraSize02，并且需要将之前在监视器面板中为CameraSize01设置的各项值保留下来，如果直接修改，如下

再看看监视器面板中的变化，之前为CameraSize01设置的序列化的值都没了

怎么办，我只是想修改一下字段的名字，不想让之前为该字段设置的值丢失，就需要用到下面办法

public class shishi : MonoBehaviour

    [FormerlySerializedAs("CameraSize01")]
    public CameraSizeHandler CameraSize02;

    [System.Serializable]
    public class CameraSizeHandler
    
        public Color BackgroundColor = Color.gray;
        public Rect ViewPortRect = new Rect(0.0f, 0.0f, 1.0f, 1.0f); 
        public RectOffset ViewPortOffset; 
        public Vector2 CanvasMargin = new Vector2(22.0f, 22.0f);
        public float MaxSpeed = 1000.0f;
        bool enabled = false;
