Unity拷贝运行时数据的世界Trans信息可以得到json数据，稍微改装一下就可以得到对象数据了（没找到官方对应的接口，如果有知道的可以评论区留言），如下图：

代码如下：

   [MenuItem("Assets/解析数据")]
    public static void Parse() {
        string test = @"UnityEditor.TransformWorldPlacementJSON:{{""position"":{ ""x"":0.0,""y"":0.0,""z"":-10.0},""rotation"":{ ""x"":0.0,""y"":0.0,""z"":0.0,""w"":1.0},""scale"":{ ""x"":1.0,""y"":1.0,""z"":1.0} }}";
        // 移除前缀 "UnityEditor.TransformWorldPlacementJSON:"
        string json = test.Substring(test.IndexOf(":{") + 2, test.Length - test.IndexOf(":{") - 3);
        Debug.Log(json);
        TransformWorldPlacement placement = JsonUtility.FromJson<TransformWorldPlacement>(json);

        Debug.Log("Position: " + placement.position);
        Debug.Log("Rotation: " + placement.rotation);
        Debug.Log("Scale: " + placement.scale);
    }


[System.Serializable]
public class TransformWorldPlacement
{
    public Vector3 position;
    public Quaternion rotation;
    public Vector3 scale;
}
