Question

我的地图代码：

public class Map {

    private String path;
    private int height, width;

    private Block[][] blocks;

    public Map(String loadPath)
    {

        path = loadPath;

        loadMap();

    }


    public void draw(Graphics g){

        for(int i = 0; i < blocks.length; i++){

            for(int j = 0; j < blocks[0].length; j++){

                blocks[j][i].draw(g);

            }
        }

    }

    public Block[][] getBlocks(){

        return blocks;

    }

    public void loadMap(){

        InputStream is = this.getClass().getResourceAsStream(path);
        BufferedReader br = new BufferedReader(new InputStreamReader(is));

        try{

            width = Integer.parseInt(br.readLine());
            height = Integer.parseInt(br.readLine());

            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]));

                }

            }


        }catch(NumberFormatException | IOException e){

            e.printStackTrace();

        }

    }
}

我的map1.map代码：

4
4
1 1 1 1 
1 1 1 1 
1 1 1 1 
1 1 1 1 

我不能让地图超过4，当我尝试我得到更大的地图我得到那个错误

这是我的块类：

public class Block extends Rectangle {

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，我会非常感激，我非常擅长编程但是这个让我完全难过！

Answer 1

     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]));

        }

    }

看看你如何用块[height] [width]设置数组，然后分配块[x] [y]（其中x可预测地循环直到宽度和y高度），这是另一种方式。 这就是为什么你要吹阵列索引。

出于同样的原因，你的绘图功能看起来也是可疑的。
