如何通过名称找到所有特定的子游戏对象并将它们添加到列表中？

Question

using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class SpinableObject
{
    public Transform t;
    public float rotationSpeed;
    public float minSpeed;
    public float maxSpeed;
    public float speedRate;
    public bool slowDown;

    public void RotateObject()
    {
        if (rotationSpeed > maxSpeed)
            slowDown = true;
        else if (rotationSpeed < minSpeed)
            slowDown = false;

        rotationSpeed = (slowDown) ? rotationSpeed - 0.1f : rotationSpeed + 0.1f;
        t.Rotate(Vector3.forward, Time.deltaTime * rotationSpeed);
    }
}
public class SpinObject : MonoBehaviour
{
    [SerializeField]
    [Header("Global Rotation")]
    [Space(5)]
    public float rotationSpeed;
    public float minSpeed;
    public float maxSpeed;
    public float speedRate;
    public bool slowDown;
    public List<GameObject> allObjects;


    [Space(5)]
    [Header("Rotation Mode")]
    [LabeledBool("Global Rotation", "Individual Rotation")]
    [SerializeField]
    bool _rotationMode = true;

    [Header("Individual Rotation")]
    [Space(3)]
    public SpinableObject[] individualObjects;


    private void Start()
    {
        allObjects = new List<GameObject>();
        foreach(Transform t in transform)
        {

        }
    }

    // Update is called once per frame
    void Update()
    {
        if (_rotationMode == false)
        {

            foreach (var spinner in individualObjects)
                spinner.RotateObject();
        }
        else
        {
            for (int i = 0; i < allObjects.Count; i++)
            {
                RotateAllObjects(allObjects[i].transform);
            }
        }
    }

    private void RotateAllObjects(Transform t)
    {
        if (rotationSpeed > maxSpeed)
            slowDown = true;
        else if (rotationSpeed < minSpeed)
            slowDown = false;

        rotationSpeed = (slowDown) ? rotationSpeed - 0.1f : rotationSpeed + 0.1f;
        t.Rotate(Vector3.forward, Time.deltaTime * rotationSpeed);
    }
}

在开始部分中，我想添加子对象的名称，而不是标记为“螺旋桨”，我有4个子对象："Propeller1“、"Propeller2”、"Propeller3“、"Propeller4”

我想将这4个对象添加到allObjects中，这样它将只旋转脚本附加到的该对象的4个属性。因为我要将对象克隆给更多的人，所以我不想使用FindByTag。

Answer 1

如果要添加包含脚本的GameObject的所有子元素：

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

其他选项，以防您想要添加来自其他gameObjects的子级：

您可以通过名称找到GameObjects。甚至是孩子们也在走这条路。例如：

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

如果您的孩子有您给出的名字作为例子，您可以这样做：

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

如果这只是一次调用，我建议使用以下代码片段：

// 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);
    }
}
