如何在java代码中随机生成tile

我有一个关于java中随机生成sprite表瓷砖的问题。每当我尝试使用for循环时，随机生成每毫秒或更快地改变一次。我很困惑，不知道从哪里开始。如果有人能想出一些简单的代码让乞丐掌握随机生成的概念

下面是我用来生成平面图的代码/

public class Map {

    Random random = new Random();

    public static int mapxDirection;
    public static int mapx = 1;
    public static int bgSpeed = 20;
    public static int grass = 16;
    public static int dirt = 0;
    public static int stone = 1;
    public static int waterup = 2;
    public static int waterside = 18;
    public static int glass = 17;
    public static int chicken = 32;
    public static int steak = 33;
    public static int mapSpeed = 3;

    public static BufferedImage[] sprites;

    public void renderMap(Graphics g) {

        final int width = 32;
        final int height = 32;
        final int rows = 16;
        final int cols = 16;

        sprites = new BufferedImage[rows * cols];

        BufferedImage spritesheet = null;
        try {
            spritesheet = ImageIO.read(new File("res/SpriteSheet.png"));
        } catch (IOException e) {

            e.printStackTrace();
        }

        for (int i = 0; i < rows; i++) {
            for (int j = 0; j < cols; j++) {
                sprites[(i * cols) + j] = spritesheet.getSubimage(i * width, j
                        * height, width, height);
            }
        }

        for (int i = 0; i < 2000; i += 32) {
            g.drawImage(sprites[grass], Map.mapx + i, 259, null);
        }

        for (int i = 0; i < 2000; i += 32) {
            for (int j = 291; j <= 508; j += 32) {
                g.drawImage(sprites[dirt], Map.mapx + i, j, null);
            }
        }
        for (int i = 0; i < 2000; i += 32) {
            for (int j = 508; j <= 540; j += 32) {
                g.drawImage(sprites[stone], Map.mapx + i, j - 3, null);
            }
        }
    }
}

有多种方法可以做到这一点，这还取决于您想要实现的随机生成的类型。例如，您需要完全随机化每个磁贴还是加载随机块。流行的游戏Minecraft使用随机卡盘生成的方法

如果你对游戏编程不熟悉，我建议你去看看。他教你一个简单而好的方法来加载精灵表，还教你如何加载和创建一个绘画水平。尽管他正在制作一个平台，你可以很容易地将同样的方法转换成自上而下的游戏

下面是我如何创建一个随机生成的地图。首先，我将创建一个名为GameObject的抽象类。您创建的每个对象都将扩展该类

public abstract class GameObject {

    protected float x, y;
    protected ObjectId id;
    protected float velX= 0, velY = 0;

    protected boolean falling = true;
    protected boolean jumping = false;

    public GameObject(float x, float y, ObjectId id) {
        this.x = x;
        this.y = y;
        this.id = id;
    }

    public abstract void tick(LinkedList<GameObject> object);
    public abstract void render(Graphics g);
    public abstract Rectangle getBounds();

    public float getX() { return x; }
    public float getY() { return y; }
    public float getVelX() { return velX; }
    public float getVelY() { return velY; }
    public boolean isFalling() { return falling; }
    public boolean isJumping() { return jumping; }

    public void setX(float x) { this.x = x; }
    public void setY(float y) { this.y = y; }
    public void setVelX(float velX) { this.velX = velX; }
    public void setVelY(float velY) { this.velY = velY; }
    public void setFalling(boolean falling) { this.falling = falling; }
    public void setJumping(boolean jumping) { this.jumping = jumping; }

    public ObjectId getId() { return id; }
}

感觉到这篇文章越来越大，我将把其余的留给你，如果你喜欢，我可以看到你的源代码，我正在使用的项目。这也是RealTutsGML在其教程中使用的相同方法

我发现您可以使用Map.mapx而不是只编写变量mapx，而不需要映射。此外，您的数据应始终是私有的或受保护的。我还建议创建一个变量，这样保存贴图大小

public class Block extends GameObject {

    private boolean animate = true;

    Texture tex = Game.getInstance();
    private int type;

    public Block(float x, float y, int type, ObjectId id) {
        super(x, y, id);
        this.type = type;
    }

    public void tick(LinkedList<GameObject> object) {
        bAnimate.runAnimation();
    }

    public void render(Graphics g) {
        if (type == 0) g.drawImage(tex.red_block[0], (int)x, (int)y, null); // Red Block
        if (type == 1) g.drawImage(tex.green_block[0], (int)x, (int)y, null); // Blue Block
        if (type == 2) g.drawImage(tex.blue_block[0], (int)x, (int)y, null); // Green Block
        if (type == 3) g.drawImage(tex.yellow_block[0], (int)x, (int)y, null); // Yellow Block
        if (type == 4) g.drawImage(tex.orange_block[0], (int)x, (int)y, null); // Orange Block
        if (type == 5) g.drawImage(tex.pink_block[0], (int)x, (int)y, null); // Pink Block
    }

    public Rectangle getBounds() {
        return new Rectangle((int)x, (int)y, 32, 32);
    }

}

addObject(new Block(x * 32, y * 32, random.nextInt(6), ObjectId.Block)); 

private static int mapSize = 2000;

这只是为了，如果你想改变地图的大小，你不必替换多个数字

我希望这对你有帮助

这是一个列表。

我看到您在初始化随机对象后没有在任何地方使用过它。你到底在这里做什么？你是在尝试生成随机数量的瓷砖吗？还是随机放置瓷砖？或者随机大小的瓷砖？我正在尝试随机生成瓷砖的位置

private static int mapSize = 2000;
