Eclipse 基本平台

我一直在尝试制作一个基本的平台游戏，但我无法继续，除非我能够阅读游戏1面板的外部文本文档以获取地图。我将txt文档包括在与其他项目和Game1Panel相同的文件夹中，但没有任何更改。当我使用终端打开Game1时，它只会显示一个黑屏。。如何让Game1Panel中的bufferedreader在Eclipse中读取外部txt文档/

import javax.swing.JPanel; 
import java.awt.*;
import java.awt.image.*;
import java.awt.event.*;

public class Game1Panel extends JPanel implements Runnable {

public static final int WIDTH = 400;
public static final int HEIGHT = 400;

private Thread thread;
private boolean running;

private BufferedImage image;
private Graphics2D g;

private int FPS = 30;
private int targetTime = 1000 / FPS;

private TileMap1 tileMap;

public Game1Panel () {

    super();
    setPreferredSize(new Dimension(WIDTH, HEIGHT));
    setFocusable(true);
    requestFocus();

}

public void addNotify() {

    super.addNotify();
    if(thread == null) {
        thread = new Thread(this);
        thread.start();

    }
}

public void run() {

    init();

    long startTime;
    long urdTime;
    long waitTime;

    while(running) {

        startTime = System.nanoTime();

        update();
        render();
        draw();

        urdTime = (System.nanoTime() - startTime) / 1000000; 
        waitTime = targetTime - urdTime;

        try{
            Thread.sleep(waitTime);
        }
        catch(Exception e) {
        }
    }
    }

    private void init() {

        running = true;

        image = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB);
        g = (Graphics2D) image.getGraphics();

        tileMap = new TileMap1("TestMap.txt", 32);

    }

    private void update() {

        tileMap.update();
    }

    private void render() {

        tileMap.draw(g);

    }

    private void draw() {
        Graphics g2 = getGraphics();
        g2.drawImage(image, 0, 0, null);
        g2.dispose();
    }
}

}

Do new Files.getAbsolutePath以查看程序在何处查找该文件，以及该文件是否确实存在。此外，调试的第一条规则是不要在出现问题的try块之后执行catchException{}。我在哪里向TileMap1构造函数中添加新文件。getAbsolutePath？在哪里定义了？在哪里尝试从文件中读取。

            int rc = map[row][col];

            if(rc == 0) {
                g.setColor(Color.BLACK);
            }
            if(rc == 1) {

            }

            g.fillRect(x + col * tileSize, y + row * tileSize, tileSize, tileSize);

        }
    }
