如何从另一个脚本编辑活动场景的游戏对象？

Question

我正在制作一个 Unity 项目，我需要从另一个不同的脚本（未链接到该活动场景）编辑当前活动场景的某些 UI 的文本。

我做的是

            Scene scene = SceneManager.GetActiveScene();
            Debug.Log (scene.name);
            if (scene.name == "RangeView") 
            {
                List<GameObject> activeObjects = new List<GameObject>();
                scene.GetRootGameObjects( activeObjects );
                for (int i = 0; i < activeObjects.Count; ++i)
                {
                    GameObject gameObject = activeObjects[ i ];
                    if (gameObject.name == "Clubdigit") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    } 
                    else if (gameObject.name == "Balldigit") {
                        gameObject.GetComponent<Text>().text = 10.ToString ();
                    } else if (gameObject.name == "Distancedigit") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    } else if (gameObject.name == "Ballspeeddigit") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    } else if (gameObject.name == "Distancedigit2") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    } else if (gameObject.name == "Backspindigit") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    } else if (gameObject.name == "Sidespindigit") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    }else if (gameObject.name == "Launchangleindigit") {
                        gameObject.GetComponent<Text> ().text = 10.ToString ();
                    }
                }

            }

更新未体现在场景中。如何更新到活动场景？

我找到方法了，我需要搜索GameObject的child。

                List<GameObject> activeObjects = new List<GameObject>();
                scene.GetRootGameObjects( activeObjects );
                for (int i = 0; i < activeObjects.Count; ++i)
                {
                    GameObject gameObject = activeObjects[ i ];
                    Debug.Log (gameObject.name);
                    if (gameObject.name == "Canvas") {
                        foreach (Transform firstchild in gameObject.transform) {
                            Debug.Log ("firstchild name " + firstchild.name);
                            if (firstchild.name == "Swinginfo") {
                                foreach (Transform secondchild in firstchild.transform) {
                                    if (secondchild.name == "Clubdigit") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//result[0].ToString();
                                    } 
                                    else if (secondchild.name == "Balldigit") {
                                        secondchild.GetComponent<Text>().text = 10.ToString ();//result[0].ToString();
                                    } else if (secondchild.name == "Distancedigit") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//0.ToString ();
                                    } 
                                }

                            }else if(firstchild.name == "Swinginfo2"){
                                foreach (Transform secondchild in firstchild.transform) {
                                    if (secondchild.name == "Ballspeeddigit") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//result[0].ToString ();
                                    } else if (secondchild.name == "Distancedigit2") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//0.ToString ();
                                    } else if (secondchild.name == "Backspindigit") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//12.ToString ();
                                    } else if (secondchild.name == "Sidespindigit") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//13.ToString ();
                                    }else if (secondchild.name == "Launchangleindigit") {
                                        secondchild.GetComponent<Text> ().text = 10.ToString ();//result[3].ToString ();
                                    }
                                }

                            }
                        }
                        break;
                    } 

                }

编辑：根据提示，我最近的更新是

            if (scene.name == "RangeView") 
            {
                List<String> objectsToChange = new List<String> () {
                    "Balldigit",
                    "Distancedigit",
                    "Ballspeeddigit",
                    "Distancedigit2",
                    "Backspindigit",
                    "Sidespindigit",
                    "Launchangleindigit"
                };
                List<GameObject> activeObjects = new List<GameObject>();
                scene.GetRootGameObjects( activeObjects );
                for (int i = 0; i < activeObjects.Count; ++i)
                {
                    GameObject gameObject = activeObjects[ i ];
                    Debug.Log (gameObject.name);
                    if (gameObject.name == "Canvas") 
                    {
                        foreach (Transform firstchild in gameObject.transform) {
                            Debug.Log ("firstchild name " + firstchild.name);
                            if (firstchild.name == "Swinginfo") {
                                foreach (Transform secondchild in firstchild.transform) {
                                    Debug.Log ("secondchild name " + secondchild.name);
                                    if (objectsToChange.Contains(secondchild.name)) 
                                    {
                                        secondchild.GetComponent<Text>().text = 10.ToString();
                                    }
                                }

                            }else if(firstchild.name == "Swinginfo2"){
                                foreach (Transform secondchild in firstchild.transform) {
                                    Debug.Log ("secondchild name " + secondchild.name);
                                    if (objectsToChange.Contains(secondchild.name)) 
                                    {
                                        secondchild.GetComponent<Text>().text = 10.ToString();
                                    }
                                }

                            }
                        }
                        break;
                    } 

                }

            }

我看到你找到了解决方案，太棒了。如果您能在 Whosebug 中分享解决方案，那就太棒了，这样任何遇到类似问题的人都可以使用您的解决方案来帮助他们。作为奖励，如果您愿意，可以对您的代码进行一些重构，使其更易于管理和阅读。

// Put the dependency Using System.Linq; at the top

List<String> objectsToChange = new List<String>() 
{
  "Balldigit",
  "Distancedigit",
  "Ballspeeddigit",
  "Distancedigit2",
  "Backspindigit",
  "Sidespindigit",
  "Launchangleindigit"
}

Scene scene = SceneManager.GetActiveScene();
Debug.Log (scene.name);

if (scene.name == "RangeView") 
{
    List<GameObject> activeObjects = new List<GameObject>();
    scene.GetRootGameObjects( activeObjects );
    foreach (GameObject activeObject in activeObjects)
    {
        if (objectsToChange.Contains(activeObject.name)) 
        {
          activeObject.GetComponent<Text>().text = 10.ToString();
        }
    }

}
