            {
                RotateAllObjects(allObjects[i].transform);

}

在开始之内我想按名称添加子对象而不是标记＆＃34; Propeller＆＃34; 我有4个子对象：＆＃34; Propeller1＆＃34; ，＆＃34; Propeller2＆＃34; ，＆＃34; Propeller3＆＃34; ，＆＃34; Propeller4＆＃34;

我想将这4个对象添加到allObjects 因此，它将仅旋转脚本附加到此对象的4个主题。由于我将对象克隆到更多，我不想使用FindByTag。

Answer 1

如果要添加GameObject中包含脚本的所有子项：

private void Start()
    {
        allObjects = new List<GameObject>();
        foreach(Transform child in transform)
        {
            allObjects.Add(child.gameObject)
        }
    }

如果您想要从其他游戏对象添加子项，则需要其他选项：

您可以按名称找到GameObjects。甚至孩子们都在使用这条路。例如：

   aFinger = transform.Find("LeftShoulder/Arm/Hand/Finger");

如果你的孩子有你给出的名字作为例子，你可以这样做：

String Prefix = Propeller;
String nameGO;

for(int i = 1; i < 4; i++)
{
   nameGO = Propeller + i;
   GameObject mGameObject = transform.Find("PathToChildren/nameGO");
  //Now rotate or do something with it
}

Answer 2

如果这只是一次性通话，我建议您使用此代码段：

// names you want to search for
string[] searchForNames = new string[] { "Propeller1" , "Propeller2" , "Propeller3" , "Propeller4" };

// list of objects that matches the search
List<GameObject> wantedObjects = new List<GameObject>();
// placeholder for all objects in the current scent
List<GameObject> allObjects = new List<GameObjects>();
// retrieve all objects from active scene ( wont retrieve objects marked with DontDestroyOnLoad from other scenes )
SceneManager.GetActiveScene()GetRootGameObjects( allObjects );
// iterate through all objects found in the current scene
foreach(GameObject obj in allObjects)
{
    // check if name is contained by searchForNames array
    if(searchForNames.Contains(obj.name))
    {
        // add to the matching list
        wantedObjects.Add(obj);
    }
}

如何通过名称找到所有特定的儿童游戏对象并将其添加到列表中？
