c# - 生成新对象到随机对象的位置

Question

我需要帮助，我有一个生成关卡的代码，每次生成都是随机发生的，所以我无法做到，当在关卡的某个部分达到触发器时，在关卡结束时在最后一个平台上，生成了更多平台，我尝试通过 pos = GameObject.Find("Platform 4 End Platform(Clone)").transform.position; 搜索对象，但是在最后我没有成功，有人可以解释如何做到最好吗？下面附上所有代码，如我有生成等。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using DG.Tweening;

public class LevelGeneratorRock : MonoBehaviour
{

    [SerializeField]
    private GameObject startPlatform, endPlatform, platformPrefab, triggerPlatform;

    private float blockWidth = 0.5f, blockHeight = 0.2f;

    [SerializeField]
    private int amountToSpawn = 100;
    private int beginAmount = 0;


    public Vector3 pos;



    private List<GameObject> spawnedPlatforms = new List<GameObject>();

    [SerializeField]
    private GameObject playerPrefab;

    void Awake()
    {
        beginAmount = 0;
        amountToSpawn = 10;
        InstantiateLevel();
    }
    const int MAX_PLATFORMS = 100;
    void InstantiateLevel()
    {

        // Notice the conditional changed here
        for (int i = beginAmount; i < beginAmount + amountToSpawn; i++)
        {

            GameObject newPlatform;

            if (i == 0)
            {
                newPlatform = Instantiate(startPlatform);
            }
            else if (i == MAX_PLATFORMS)
            { // End Platform
                newPlatform = Instantiate(endPlatform);
                newPlatform.tag = "EndPlatform";
            }
            else if (i % 10 == 0)
            {
                newPlatform = Instantiate(triggerPlatform);
                newPlatform.tag = "triggerPlatform";
            }
            else
            { // Normal platform
                newPlatform = Instantiate(platformPrefab);
            }




            spawnedPlatforms.Add(newPlatform);
            int left = Random.Range(0, 2);

            if (left == 0)
            {
               
                newPlatform.transform.position =
                    new Vector3(pos.x - blockWidth, pos.y + blockHeight, pos.z);

            }
            else
            {
               
                newPlatform.transform.position =
                    new Vector3(pos.x, pos.y + blockHeight, pos.z + blockWidth);

            }
            
            pos = newPlatform.transform.position;

            // fancy animation
            if (i < 25)
            {

                float pos = newPlatform.transform.position.y;

                newPlatform.transform.position =
                    new Vector3(newPlatform.transform.position.x,
                    newPlatform.transform.position.y - blockHeight * 3f,
                    newPlatform.transform.position.z);

                newPlatform.transform.DOLocalMoveY(pos, 0.3f).SetDelay(i * 0.1f);

            }

        } // for loop



    } // instantiate level

    void OnCollisionEnter(Collision other)
    {
        if (other.gameObject.CompareTag("triggerPlatform"))
        {
            // Tell the level generator to spawn more platforms
            {
                beginAmount = beginAmount + 11;
                amountToSpawn = 10;
                InstantiateLevel();
            }
        }









    }
}// class

看起来您拥有 List spawnedPlatforms 中的所有平台。您也已经设置了标签，因此您可以遍历列表并检查“EndPlatform”的标签，对吗？如果您正在寻找特定的 EndPlatform，

var platformToFind = "3";
foreach (var platform in spawnedPlatforms) {
    if (platform.tag == "EndPlatform" && platform.name.Contains(platformToFind)) {
        // Do something
    }
}

根据您的评论，听起来您希望每次玩家跳上 10 个平台时，您都希望再创建 10 个平台。

这意味着每 10 个平台需要一个触发平台。因此，您应该将 if (i == amountToSpawn - 90) 更改为 if (i % 10 == 0)。这称为模运算符，它为您提供除法的余数。例如。 13 % 10 = 3，或者对于我们的情况:10 % 0 = 0、20 % 0 = 0、30 % 0 = 0，等等。

它看起来像这样:

void Awake()
{
    beginAmount = 0;
    amountToSpawn = 10;
    InstantiateLevel();
}
const int MAX_PLATFORMS = 100;
void InstantiateLevel()
{

// Notice the conditional changed here
for (int i = beginAmount; i < beginAmount + amountToSpawn; i++)  {

            GameObject newPlatform;

            if (i == 0) {
                newPlatform = Instantiate(startPlatform);
            } else if (i == MAX_PLATFORMS) { // End Platform
            } else if (i % 10 == 0) {
                newPlatform = Instantiate(triggerPlatform);
                newPlatform.tag = "triggerPlatform";
            } else { // Normal platform
            }
}

然后在你的播放器脚本中，你会有类似的东西:

void OnCollisionEnter(Collision other) {
   if (other.gameObject.tag.CompareTag("triggerPlatform")) {
       // Tell the level generator to spawn more platforms
       levelGenerator.beginAmount = levelGenerator.beginAmount + 11;
       levelGenerator.amountToSpawn = 10;
       levelGenerator.InstantiateLevel();
   }
}
