我不能让地图变大到超过4，当我试着把地图变大时，我就得到了这个错误

这是我的积木课：

公共类块扩展矩形{

private static final long serialVersionUID = 1L;

public static final int blockSize = 64;
private int id;

public Block(int x, int y, int id) {
    setBounds(x, y, blockSize, blockSize);
    this.id = id;
}

public void tick() {

}

public void draw(Graphics g) {
    g.setColor(Color.BLACK);

    if(id != 0){

    g.fillRect(x - (int)GameState.xOffset, y - (int)GameState.yOffset, width, height);
    }
}

//getters and setters

public void setID(int id){

    this.id = id;

}

public int getID(){

    return id;
}

}

如果有人能帮助我，我将不胜感激，我非常擅长编程，但这一次让我彻底难倒了！

blocks=newblock[height][width]；
     blocks = new Block[height][width];

    for(int y = 0; y < height; y++){

    String line = br.readLine();

    String[] tokens = line.split("\\s+");

        for(int x = 0; x < width; x++){

            blocks[x][y]= new Block(x * Block.blockSize ,y * Block.blockSize, Integer.parseInt(tokens[x]));

        }

    }

对于（int y=0；y

查看如何使用块[height][width]设置数组，然后将块[x][y]分配给它们（其中x可以预测循环到width和y height），这是另一种方式。这就是为什么要破坏数组索引

出于同样的原因，你的绘图功能看起来也是可疑的。

我将x改为宽度，y改为高度，没有luckCan你能给我看它爆炸的地图吗？你说它在4点工作吗？我用另一种方式，在代码中设置高度和宽度，而不是在地图中。不过谢谢你的帮助！
