Java Tiled地图正在横向绘制

Question

Recently I've been trying to make a little game for my learning purpose but I got stuck. I was able to generate a map from a .txt file but then it seems to paint it sideways?

this is my map loaded which reads from a text file and add them to an ArrayList. Width is 20 Height is 10. Same thing applies in my map 20 lines wide 10 down.

public void loadMap(String name) {
        try {
            this.name = name;

            FileInputStream file_stream = new FileInputStream(name);
            DataInputStream in = new DataInputStream(file_stream);
            BufferedReader br = new BufferedReader(new InputStreamReader(in));

            map = new Tile[WIDTH][HEIGHT];

            String line;
            int y = 0;
            while ((line = br.readLine()) != null) {
                String[] tokens = line.split(" ");
                for (int x = 0; x < WIDTH; x++) {
                    boolean f = false;
                    if (Integer.parseInt(tokens[x]) == 1)
                        f = true;
                    Tile tile = new Tile(y, x, f, Integer.parseInt(tokens[x]));
                    tiles.add(tile);
                    map[x][y] = tile;
                    System.out.println("adding tile (x: " + x + " y: " + y + ") " + f + " " + Integer.parseInt(tokens[x]));
                }
                y++;
            }
            in.close();
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null, "The map: " + name + " was not found.");
            e.printStackTrace();
        }
    }

This is the draw method for the map

public void paint(Graphics2D g) {
        for (Tile t : getTiles()) {
            t.draw(g);
        //g.draw(t.getBounds());
        }
    }

Here is an example map

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0
0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1

The way it paints the map is basically a vertical version of this instead of the correct way like it is above. I have tried messing with the numbers within the mapLoaded (width, height) and switching the x and y around but nothing seems to work. Please help

You simply need to change Tile tile = new Tile(y, x, f, Integer.parseInt(tokens[x])); to Tile tile = new Tile(x, y, f, Integer.parseInt(tokens[x])); .

Everytime you're making a new Tile, you're switching x and y which is causing your problems.
