Unity：從數組實例化預制件，為它們設置一個標簽，等待 2 秒並銷毀每個標記的對象

Question

我正在嘗試創建一個腳本（在 javascript 中，但最好使用 C#）來執行以下步驟：

(1) 創建主相機的克隆； (1) 從編輯器中設置的數組實例化預制件； (2) 為所有這些實例化的游戲對象設置一個標簽（相同的）； （3）等待1秒； (4) 銷毀每個持有 (2) 中設置的標簽的游戲​​對象，並銷毀克隆的相機。

我想出了以下代碼，但它不起作用。 任何人都可以幫忙嗎？

代碼更新

using UnityEngine;
using System.Collections;

public class PreLoader : MonoBehaviour {
    //Array of Objects To Spawn
        public GameObject[] objectsToSpawn;

    // Use this for initialization
    void Start () 
        {
            StartCoroutine(SpawnItemsFromArray());
        }

        IEnumerator SpawnItemsFromArray() //You can name this however you like
        {
            //Instantiates another camera as a GameObject (easy access to Components and removal of Camera)
            GameObject cam1 = Instantiate(GameObject.FindWithTag("MainCamera"), Vector3.zero, Quaternion.FromToRotation(new Vector3(0, 0, 0), new Vector3(0, 0, 1))) as GameObject;
            //Gets AudioListener Component and disables it
            cam1.GetComponent<AudioListener>().enabled = false;

            float space = 1;
            float originalSpace = -3;

            for (int i = 0; i < objectsToSpawn.Length; i++)
            {
                //You'll have to Instantiate as a GameObject to change its tag
                GameObject go = Instantiate(objectsToSpawn[i], new Vector3(originalSpace, 0, 10.0f), transform.rotation) as GameObject;
                originalSpace += space;
                //Changes the tag to "Holder"
                go.tag = "Holder";

                //This will change the tag of the GameObject that this script is attached too
                //gameObject.tag = "Holder"; 
            }
            //Waits for 2 Sec
            yield return new WaitForSeconds(2);

            //This will destroy (new Camera) and all that have tag "Holder"
            GameObject[] goDestroy = GameObject.FindGameObjectsWithTag("Holder");
            foreach (GameObject goHolder in goDestroy) Destroy(goHolder);
            Destroy(cam1);
        }
}

Answer 1

據我所知yield WaitForSeconds(2); 僅適用於IEnumerator 。 這是用StartCoroutine(**IEnumeratorMethodName**());調用的StartCoroutine(**IEnumeratorMethodName**());

您要求提供 C# 代碼，所以我希望這會有所幫助：（祝您好運）

void Start () 
{
    StartCoroutine(SpawnItemsFromArray());
}

IEnumerator SpawnItemsFromArray() //You can name this however you like
{
    //Instantiates another camera as a GameObject (easy access to Components and removal of Camera)
    GameObject cam1 = Instantiate(GameObject.FindWithTag("MainCamera"), Vector3.zero, Quaternion.FromToRotation(new Vector3(0, 0, 0), new Vector3(0, 0, 1))) as GameObject;
    //Gets AudioListener Component and disables it
    cam1.GetComponent<AudioListener>().enabled = false;
    //If you added this script to the Main Camera uncomment line below and add the appropriate script name to it
    //cam1.GetComponent<**ScriptName**>().enabled = false; //This will make sure the new instantiated Camera doesn't run this script (Otherwise lots of cameras/GameObjects will be spawned

    float space = 1;
    float originalSpace = -3;

    for (int i = 0; i < objectsToSpawn.Length; i++)
    {
        //You'll have to Instantiate as a GameObject to change its tag
        GameObject go = Instantiate(objectsToSpawn[i], new Vector3(originalSpace, 0, 10.0f), transform.rotation) as GameObject;
        originalSpace += space;
        //Changes the tag to "Holder"
        go.tag = "Holder";

        //This will change the tag of the GameObject that this script is attached too
        //gameObject.tag = "Holder"; 
    }
    //Waits for 2 Sec
    yield return new WaitForSeconds(2);

    //This will destroy (new Camera) and all that have tag "Holder"
    GameObject[] goDestroy = GameObject.FindGameObjectsWithTag("Holder");
    foreach (GameObject goHolder in goDestroy) Destroy(goHolder);
    Destroy(cam1);
}
