好的,以下是一个用Java语言实现递归分割算法生成迷宫的示例代码:
```java
import java.util.*;
public class MazeGenerator {
private int width;
private int height;
private int[][] maze;
private Random rand;
public MazeGenerator(int width, int height) {
this.width = width;
this.height = height;
maze = new int[width][height];
rand = new Random();
}
public void generateMaze() {
// Initialize maze with walls
for (int i = 0; i < width; i++) {
for (int j = 0; j < height; j++) {
maze[i][j] = 1;
}
}
// Create passages
divide(0, 0, width - 1, height - 1);
}
private void divide(int x1, int y1, int x2, int y2) {
if (x2 < x1 || y2 < y1) {
return;
}
// Choose orientation (horizontal or vertical)
boolean horizontal = rand.nextBoolean();
// Choose position to divide the area
int x = horizontal ? x1 + rand.nextInt(x2 - x1 + 1) : x1;
int y = horizontal ? y1 : y1 + rand.nextInt(y2 - y1 + 1);
// Create a passage at the chosen position
for (int i = horizontal ? x : x1; i <= (horizontal ? x : x2); i++) {
maze[i][y] = 0;
}
for (int j = horizontal ? y1 : y; j <= (horizontal ? y2 : y); j++) {
maze[x][j] = 0;
}
// Recursively divide the areas
divide(x1, y1, x - 1, y - 1);
divide(x + 1, y + 1, x2, y2);
divide(x + 1, y1, x2, y - 1);
divide(x1, y + 1, x - 1, y2);
}
public void printMaze() {
for (int i = 0; i < height; i++) {
for (int j = 0; j < width; j++) {
System.out.print(maze[j][i] == 1 ? "█" : " ");
}
System.out.println();
}
}
public static void main(String[] args) {
MazeGenerator mazeGenerator = new MazeGenerator(20, 10);
mazeGenerator.generateMaze();
mazeGenerator.printMaze();
}
}
```
这个示例代码使用了递归分割算法来生成迷宫。首先,将整个迷宫初始化为全部是墙。然后,从左上角开始,将整个迷宫递归地分割成四个矩形区域,每次随机选择一个位置将当前区域分成两部分,然后在这个位置上打通一条通道。最后递归地对分割后的四个子区域进行同样的操作,直到所有的区域都被分割完成。最终得到的就是一个迷宫。
