java - 枚举类型 2Darray 迷宫

Question

我正在制作一个带有枚举类型的迷宫游戏来保存墙壁、开放空间（等）的值，但我不确定为什么这段代码不起作用，我正在尝试创建一个新板并将所有内容设置为打开，然后通过并随机为数组中的点设置值。

maze = new Cell[row][col];
for (int r = 0; r < maze.length; r++) {
    for (int c = 0; c < maze.length; c++) 
        maze[r][c].setType(CellType.OPEN);
    }

Random randomMaze = new Random();
for (int ran = 0; ran <= numWalls ; ran++){
    maze[randomMaze.nextInt(maze.length)][randomMaze.nextInt(maze.length)].setType(CellType.WALL); 

}

Answer 1

我认为，您的内部循环应该类似于

for (int c = 0; c < maze[r].length; c++)

... 与[r].

我还没有尝试过。

Answer 2

我认为你的迷宫是一个很好的班级候选人。像这样的东西应该工作：

import java.util.Random;

public class Maze {
    private int[][] mMaze;
    private int mRows;
    private int mCols;

    //enums here:
    public static int CELL_TYPE_OPEN = 0;
    public static int CELL_TYPE_WALL = 1;

    public Maze(int rows, int cols){
        mRows = rows;
        mCols = cols;
        mMaze = new int[mRows][mCols];
        for (int r = 0; r < mRows; r++) {
            for (int c = 0; c < mCols; c++) { 
                mMaze[r][c] = Maze.CELL_TYPE_OPEN;
            }
        }
    }

    public void RandomizeMaze(int numWalls){
        Random randomMaze = new Random();
        for (int ran = 0; ran <= numWalls ; ran++){
            mMaze[randomMaze.nextInt(mRows)][randomMaze.nextInt(mCols)]=(Maze.CELL_TYPE_WALL);
        }
    }

}

这会做你说的。不确定你会得到你想要的那种迷宫：

import java.util.Random;
class Maze {
    enum CellType {
        open,wall;
    }
    Maze(int n) {
        this.n=n;
        maze=new CellType[n][n];
        init();
    }
    private void init() {
        for(int i=0;i<n;i++)
            for(int j=0;j<n;j++)
                maze[i][j]=CellType.open;
    }
    void randomize(int walls) {
        init();
        Random random=new Random();
        for(int i=0;i<=walls;i++)
            maze[random.nextInt(n)][random.nextInt(n)]=CellType.wall;
    }
    public String toString() {
        StringBuffer sb=new StringBuffer();
        for(int i=0;i<n;i++) {
            for(int j=0;j<n;j++)
                switch(maze[i][j]) {
                    case open:
                        sb.append(' ');
                        break;
                    case wall:
                        sb.append('|');
                        break;
                }
            sb.append('\n');
        }
        return sb.toString();
    }
    final int n;
    CellType[][] maze;
}
public class Main {
    public static void main(String[] args) {
        Maze maze=new Maze(5);
        System.out.println(maze);
        maze.randomize(4);
        System.out.println(maze);
    }
}
