團結 - 參數超出範圍建立董事會

這裏是當我BoardGenerator.cs團結 - 參數超出範圍建立董事會

using UnityEngine; 
using System; 
using System.Collections.Generic; 
using Random = UnityEngine.Random; 

public class BoardGenerator : MonoBehaviour { 

    [Serializable] 
    public class Count{ 
     public int min; 
     public int max; 

     public Count(int m, int M){ 
      min = m; 
      max = M; 
     } 
    } 

    public int columns = 20; 
    public int rows = 20; 
    public Count wallCount = new Count (10, 20); 
    public Count moneyCount = new Count (10, 15); 
    public GameObject floorTiles; 
    public GameObject wallTiles; 
    public GameObject moneyTiles; 
    public GameObject[] enemyTiles; 

    private Transform board; 
    private List <Vector3> positions = new List<Vector3>(); 

    void BoardSetup(){ 
     board = new GameObject ("Board").transform; 

     for (int x=-1; x<columns+1; x++) { 
      for (int y=-1; y<rows+1; y++){ 
       GameObject toInstantiate = floorTiles; 
       if(x==-1||x==columns||y==-1||y==rows) 
        toInstantiate = wallTiles; 

       GameObject instance = Instantiate (toInstantiate, new Vector3 (x, y, 0f), Quaternion.identity) as GameObject; 
       instance.transform.SetParent (board); 
      } 
     } 

    } 

    Vector3 RandPos(){ 
     int randomIndex = Random.Range (0, positions.Count); 
     Vector3 randPos = positions [randomIndex]; 
     positions.RemoveAt (randomIndex); 
     return randPos; 
    } 

    void MoneyWallRandom (GameObject tileObj, int m, int M) 
    { 
     int objectCount = Random.Range (m, M); 

     for(int i = 0; i < objectCount; i++) 
     { 
      Vector3 randomPosition = RandPos(); 
      GameObject tile = tileObj; 
      Instantiate(tile, randomPosition, Quaternion.identity); 
     } 
    } 

    void EnemyRandom (GameObject[] tileObj, int m, int M) 
    { 
     int objectCount = Random.Range (m, M); 

     for(int i = 0; i < objectCount; i++) 
     { 
      Vector3 randomPosition = RandPos(); 
      GameObject tile = tileObj[Random.Range (0, tileObj.Length)]; 
      Instantiate(tile, randomPosition, Quaternion.identity); 
     } 
    } 

    public void BoardSetup (int level) 
    { 
     BoardSetup(); 
     MoneyWallRandom (wallTiles, wallCount.min, wallCount.max); 
     MoneyWallRandom (moneyTiles, moneyCount.min, moneyCount.max); 
     int enemyCount = level + 3; 
     EnemyRandom (enemyTiles, enemyCount, enemyCount); 
    } 
}

而且我GameManager.cs

using UnityEngine; 
using System.Collections; 

public class GameManager : MonoBehaviour { 

    public BoardGenerator boardScript; 

    private int level = 1; 

    // Use this for initialization 
    void Awake() { 

     boardScript = GetComponent<BoardGenerator>(); 
     InitGame(); 
    } 

    void InitGame(){ 
     boardScript.BoardSetup (level); 
    } 

    // Update is called once per frame 
    void Update() { 

    } 
}

該主板成功創建，但敵人和金錢瓷磚可以」由於某些原因而被創建。這裏有

ArgumentOutOfRangeException: Argument is out of range. 
Parameter name: index 
System.Collections.Generic.List`1[UnityEngine.Vector3].get_Item (Int32 index) (at /Users/builduser/buildslave/mono-runtime-and-classlibs/build/mcs/class/corlib/System.Collections.Generic/List.cs:633) 
BoardGenerator.RandPos() (at Assets/_Scripts/BoardGenerator.cs:50) 
BoardGenerator.MoneyWallRandom (UnityEngine.GameObject tileObj, Int32 m, Int32 M) (at Assets/_Scripts/BoardGenerator.cs:61) 
BoardGenerator.BoardSetup (Int32 level) (at Assets/_Scripts/BoardGenerator.cs:83) 
GameManager.InitGame() (at Assets/_Scripts/GameManager.cs:18) 
GameManager.Awake() (at Assets/_Scripts/GameManager.cs:14)

我不知道我怎麼能解決這個問題....

TL在控制檯中的錯誤;博士positions永遠不會被初始化爲不是空列表，以便randomIndex以外的任何總是爲0，所以在拋出異常的那一行，你試圖刪除索引爲0的項目，但是列表中沒有項目，所以它會拋出一個異常。

正確初始化positions並解決了您的問題。

它在這行拋出異常：

positions.RemoveAt (randomIndex);

發生這種情況，因爲positions.Count爲0，因此

int randomIndex = Random.Range (0, positions.Count);

相當於

int randomIndex = Random.Range (0, 0);

被equivalen噸至

int randomIndex = 0;

沒有什麼從positions在任何索引中刪除的，因爲positions是一個空列表。
