Question

我正在按照CodeNMore进行本教程的学习，直到他说出如何加载图像和校正为止，一切都很好。它没有给我任何错误，但是除了空白窗口外没有显示任何其他内容。我尝试查看他的代码，然后查看我的代码，但没有发现任何区别。

Game.java：

package dev.dylandummy.masterquest;
import java.awt.Graphics;
import java.awt.image.BufferStrategy;
import java.awt.image.BufferedImage;

import dev.dylandummy.masterquest.display.Display;
import dev.dylandummy.masterquest.gfx.ImageLoader;

public class Game implements Runnable {

    private Display display;
    public int width, height;
    public String title;

    private boolean running = false;
    private Thread thread;

    private BufferStrategy bs;
    private Graphics g;

    private BufferedImage testImage;

    public Game(String title, int width, int heigth){
        this.width = width;
        this.height = heigth;
        this.title = title;
    }

    private void init() {
        display = new Display(title, width, height);
        testImage = ImageLoader.loadImage("/textures/test.png");
    }

    private void tick() {

    }

    private void render() {

        bs = display.getCanvas().getBufferStrategy();
        if(bs == null) {
            display.getCanvas().createBufferStrategy(3);
            return;
        }

        g = bs.getDrawGraphics();
        //Clear Screen
        g.clearRect(0, 0, width, height);
        //Draw Here!

        g.drawImage(testImage, 20, 20, null);

        //End Draw!
        bs.show();
        bs.dispose();   
    }

    public void run() {

        init();

        while(running) {
            tick();
            render();

        }

        stop();

    }

    public synchronized void start() {

        if(running)
            return;


        running = true;
        thread = new Thread(this);
        thread.start();

    }

    public synchronized void stop() {

        if(!running)
            return;

        running = false;
        try {
            thread.join();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

}

Display.java：

package dev.dylandummy.masterquest.display;

import java.awt.Canvas;
import java.awt.Dimension;
import javax.swing.JFrame;

public class Display {


    private JFrame frame;
    private Canvas canvas;

    private String title;
    private int width, height;

    public Display(String title, int width, int heigth) {

        this.title = title;
        this.width = width;
        this.height = heigth;

        createDisplay();
    }


    private void createDisplay() {

        frame = new JFrame(title);
        frame.setSize(width, height);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setResizable(false);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);

        canvas = new Canvas();
        canvas.setPreferredSize(new Dimension(width, height));
        canvas.setMaximumSize(new Dimension(width, height));
        canvas.setMinimumSize(new Dimension(width, height));

        frame.add(canvas);
        frame.pack();
    }

    public Canvas getCanvas(){
        return canvas;
    }



}

ImageLoader.java：

package dev.dylandummy.masterquest.gfx;

import java.awt.image.BufferedImage;
import java.io.IOException;

import javax.imageio.ImageIO;

public class ImageLoader {

    public static BufferedImage loadImage(String path) {
        try {
            return ImageIO.read(ImageLoader.class.getResource(path));
        } catch (IOException e) {
            e.printStackTrace();
            System.exit(1);
        }
        return null;
    }

}

Launcher.java：

package dev.dylandummy.masterquest;

public class Launcher {

    public static void main(String[] args) {
        Game game = new Game("The Master Quest", 640, 360);
        game.start();
    }

}

现在，对不起，如果这太多代码无法浏览，但是如果您有时间，您可以浏览一下并告诉我哪里出了问题吗？
