Question

所以我尝试使用while循环让我的程序找到通过8x8数组的路径。但是，在启动时Unity会停止响应并且必须关闭。有人可以帮助解释为什么我的代码不起作用，因为我没有看到任何错误，因为循环结束的条件发生了变化。这是源代码：

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

public class LevelGenerator : MonoBehaviour {

public int counter = 0;
int LevelX = 0;
int LevelY = 0;

int[,] LevelData = new int[8,8]{
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0},
    {0,0,0,0,0,0,0,0}
};

void Start () {
    Generate();
}

void RandomPath(){
    int NewDirection = Random.Range(0,3);
    if(NewDirection==0){
        if(LevelX!=0){
            if(LevelData[LevelX-1,LevelY]==0){
                counter++;
                LevelData[LevelX-1,LevelY]=counter;
                LevelX=LevelX-1;
            }
        }
    }else if(NewDirection==1){
        if(LevelX!=7){
            if(LevelData[LevelX+1,LevelY]==0){
                counter++;
                LevelData[LevelX+1,LevelY]=counter;
                LevelX=LevelX+1;
            }
        }
    }
    else if(NewDirection==2){
        if(LevelY!=7){
            if(LevelY!=0){
                if(LevelData[LevelX,LevelY-1]==0){
                    counter++;
                    LevelData[LevelX,LevelY+1]=counter;
                    LevelY=LevelY+1;
                }
            }else{
                counter++;
                LevelData[LevelX,LevelY+1]=counter;
                LevelY=LevelY+1;
            }
        }
    }
}

void Generate(){
    //picks a random location for the level to start and the second room, then generates a random path to the bottom of the level
    int LevelStartX = Random.Range(0,8);
    int LevelStartY = Random.Range(0,5);
    counter++;
    LevelData[LevelStartX,LevelStartY] = counter;
    Debug.Log(LevelStartX);
    Debug.Log(LevelStartY);
    int Direction = Random.Range(0,3);
    if(Direction==0){
        if(LevelStartX==0){
            counter++;
            LevelData[LevelStartX+1,LevelStartY]=counter;
            LevelX = LevelStartX+1;
            LevelY = LevelStartY;
        }else{
            counter++;
            LevelData[LevelStartX-1,LevelStartY]=counter;
            LevelX = LevelStartX-1;
            LevelY = LevelStartY;
        }
    }else if(Direction==1){
        if(LevelStartX==7){
            counter++;
            LevelData[LevelStartX-1,LevelStartY]=counter;
            LevelX = LevelStartX-1;
            LevelY = LevelStartY;
        }else{
            counter++;
            LevelData[LevelStartX+1,LevelStartY]=counter;
            LevelX = LevelStartX+1;
            LevelY = LevelStartY;
        }
    }else{
        counter++;
        LevelData[LevelStartX,LevelStartY+1]=counter;
        LevelX = LevelStartX;
        LevelY = LevelStartY+1;
    }
    while(LevelY!=7 || counter!=32){
        RandomPath();
    }
}
}

Answer 1

我检查了你的代码，发现计数器永远不会达到32（或至少通常）。这可能是因为你使用的是随机数字，每次运行时都会以不同的数字停止，因此实际工作的可能性很小

while循环导致Unity冻结
