Question

嘿所以我正试图让我的投资组合进入一个扫雷游戏进入一所学校。但我遇到了一个小问题。我正在使用团结。我一直收到这个错误： NullReferenceException：未将对象引用设置为对象的实例 SceneInitializer.Start（）（在Assets / Scripts / SceneInitializer.cs：23）

我有两个脚本一起工作。它在某个时候起作用了。但现在即使我回去它也有NULL错误。违规行标有!!!!

这是脚本一。抛出错误的那个。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SceneInitializer : MonoBehaviour {

    public GameObject BoardTilePrefab;

    void Start () {

        for (int x = 0; x < 8; x++) {
            for (int y = 0; y < 8; y++) {
                GameObject tile = AddTile (BoardTilePrefab);
                tile = Instantiate (tile);
                //Get script and atatch it to game object
                tile.AddComponent <Tile> ();
                tile.GetComponent <Tile> ().SetBomb ();
                tile.GetComponent <Tile> ().SetPosition (x, y);
                //Sets the position in world space
                tile.transform.position = tile.GetComponent <Tile> ().GetPosition();

                //Sets tag and position elements in other script
                !!!!!tile.tag = ConvertGetPositionToTag(GetComponent<Tile>().GetPosition());
            }
        }
    }





    //Methods
    public GameObject AddTile (GameObject GameTile) 
    {
        GameObject Tile = GameTile;
        return Tile;
    }

    private string ConvertGetPositionToTag (Vector2 position) {
        int positionX = (int) position.x;
        int positionY = (int) position.y;
        string sPositionX = positionX.ToString ();
        string sPositionY = positionY.ToString ();
        string toTag = sPositionX + sPositionY;
        return toTag;
    }

}

这是脚本二。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Tile : MonoBehaviour {


    private bool bomb;
    public bool isPressed;
    public bool nextToBomb;

    private Vector2 position;


    //SetBom
    public bool SetBomb ()
    {
        float randNumb = Random.Range (0.0f, 1.0f);
        if (randNumb == 1) {
            return this.bomb = true;
        } else {
            return this.bomb = false;
        }
    }

    //GetBomb
    public bool GetBomb ()
    {
        return bomb;
    }

    //SetPosition
    public void SetPosition (int x, int y) {
        this.position = new Vector2 (x, y);
    }

    public Vector2 GetPosition (){
        return position;
    }

    public void SetPressed () {
        this.isPressed = false;
    }



    //if Tile is bomb
        //You lose
    //if Tile is not bomb
        //SetPressed true
        //Check if next to bomb
            //if that tile has bomb Set NexttoBomb True
            //if that tile has no bomb
                //GetPosition tag of other tile
                //use "Check if next to bomnb" if tile is not pressed to check its neighbours



}

关于代码的任何类型的提示或指针也都是高级的。谢谢你的帮助!!!
