如何在其他脚本中设置数组

Question

您好，我正在制作一个多人射击在unity和即时通讯使用数组和需要帮助

我的情况是，我想做一个拆箱系统，选择一个随机数组，然后将它设置为classes数组列表的列表，请帮助。请告诉我这是否会选择一个随机数组: ClassesRandom；我还需要知道如何从不同的脚本设置数组

using UnityEngine;
using System.Collections;

public class SpawnNew : MonoBehaviour
{
    public GameObject[] Classes;
    public GameObject player;
    public Transform[] spawnPoints;
    public Camera spawnCam;
    public AudioListener spawnListener;
    public bool spawned = false;


    void ClassList(){

        Classes = new GameObject[10];
    }

    void OnGUI()
    {
        if (Network.isServer || Network.isClient)
        {
            if (!spawned)
            {
                if (GUI.Button(new Rect(Screen.width / 10 - 50, Screen.height / 10 - 25, 100, 50), "Spawn"))
                {
                    SpawnPlayer();
                }
            }
        }
    }

    void SpawnPlayer()
    {
        spawned = true;
        int random = Random.Range(0, spawnPoints.Length);
        Network.Instantiate(player, spawnPoints[random].position, spawnPoints[random].rotation, 0);
        spawned = true;
        spawnCam.enabled = false;
        spawnListener.enabled = false;
        spawned = true;
    }

    public void Die()
    {
        Screen.lockCursor = false;
        spawned = false;
        spawnCam.enabled = true;
        spawnListener.enabled = true;
    }
}

首先，你的数组没有初始化。您必须确保在调用SpawnPlayer方法之前填充了数组，否则将通过NullReferenceException进行填充。

是的，这个int random = Random.Range(0, yourArray.Length);会给你数组中的一个随机索引。您可以从另一个脚本中访问数组/方法，如下所示

GameObject yourObject = GameObject.Find("GameObjectNameThatHasYourScriptAttachedToIt");
if(yourObject !=null){
    yourObject.GetComponent<SpawnNew>().Classes = someOtherArray;
    // or if you want to access the method 
    // yourObject.GetComponent<SpawnNew>().SpawnPlayer();
}
