Java 从二维数组中获取值

Java 从二维数组中获取值,java,arrays,tiles,Java,Arrays,Tiles,这是我的阵列: private static int[][] map = new int[WIDTH][HEIGHT]; 我使用以下类生成平铺贴图: public class Map { public static final int CLEAR = 0; public static final int STONE = 1; public static final int GRASS = 2; public static final int DIRT = 3; public static

这是我的阵列:

private static int[][] map = new int[WIDTH][HEIGHT];
我使用以下类生成平铺贴图:

public class Map {

public static final int CLEAR = 0;
public static final int STONE = 1;
public static final int GRASS = 2;
public static final int DIRT = 3;

public static final int WIDTH = 32;
public static final int HEIGHT = 24;

public static final int TILE_SIZE = 25;

private static int[][] map = new int[WIDTH][HEIGHT];

Image air, grass, stone, dirt;

Random rand = new Random();

public Map() {

    /* default map */

    /*for(int y = 0; y < WIDTH; y++){
        map[y][y] = (rand.nextInt(2));
        System.out.println(map[y][y]);
    }*/

    for (int y = 18; y < HEIGHT; y++) {
        for (int x = 0; x < WIDTH; x++) {
            map[x][y] = STONE;
        }

    }

    for (int y = 18; y < 19; y++) {
        for (int x = 0; x < WIDTH; x++) {
            map[x][y] = GRASS;
        }

    }

    for (int y = 19; y < 20; y++) {
        for (int x = 0; x < WIDTH; x++) {
            map[x][y] = DIRT;
        }

    }

        e.printStackTrace();
    }

如何获取瓷砖的x和y坐标并将其放入矩形代码中?

我认为您需要这样的东西:

new Rectangle(x * TILE_SIZE, Y * TILE_SIZE, TILE_SIZE, TILE_SIZE);
我想你在用

private static int[]map=new int[WIDTH][HEIGHT]

来表示你的地图。所以地图的每个{x,y}代表地图上的一个点。矩形类Rectangle(intx,inty,intwidth,intheight)的构造函数用于构造一个新矩形,其左上角指定为(x,y),其宽度和高度由同名参数指定。所以我认为这很容易做到

new Rectangle(x, y, TILE_SIZE, TILE_SIZE)

同样要使用这个构造函数,你必须从{0,0}

开始地图导航,所以我的代码应该是这样的
publicstaticrectangleblockbounds(intx,inty){return(newrectangle(x,y,TILE_SIZE,TILE_SIZE))}
我该如何实际执行冲突检测呢?我知道你必须使用。相交,但我该如何设置方法?我不明白你的问题?你的意思是你不知道你指定的t点的矩形瓷砖是否与其他点相交?
new Rectangle(x, y, TILE_SIZE, TILE_SIZE)
