Ich erweitere aCanvas und es zu einem hinzufügenJFrame. Ich verstehe, dass AWT und Swing nicht gemischt werden sollten und dass das Zeichnen auf JPanel bevorzugt wird, aber ich versuche, einem Game-Engine-Tutorial zu folgen, und ich möchte daran festhalten, da ich es bisher zum Laufen gebracht habe. DasCanvas hatminimumSize, maximumSize, undprefferedSize auf die Maße von550, 400. Wenn ich einen Draw Call machegraphics.draw(0,0,550,400) Es füllt nicht den gesamten Bildschirm aus, wie es sollte. Ich habe den Draw Call auf geändertgraphics.draw(0,0,560,410) im Wesentlichen 10px hinzugefügt und es füllte den gesamten Bildschirm. Was ist falsch?

Übrigens:graphics.draw(10,10,550,400 Zeichnet das Rechteck ab der Ecke genau, damit ich nicht denke, dass der JFrame das Problem ist.

Der Hauptanruf drinnenLauncher Klasse

    public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            game.setMinimumSize(DIMENSIONS);
            game.setMaximumSize(DIMENSIONS);
            game.setPreferredSize(DIMENSIONS);

            game.frame = new JFrame(NAME);
            game.frame.setLayout(new BorderLayout());
            game.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            game.frame.add(game, BorderLayout.CENTER);
            game.frame.pack();

            game.frame.setResizable(false);
            game.frame.setLocationRelativeTo(null);
            game.frame.setVisible(true);

            Logger.log(TAG, "Game starting");
            game.start();
        }
    });
}

Der Draw Call,Launcher.HEIGHT undWIDTH sind550,400

    public void draw(float deltaTime, Graphics2D graphics) {
    graphics.setColor(Color.BLACK);
    graphics.fillRect(0, 0, 550, 400);
    graphics.setColor(Color.DARK_GRAY);
    graphics.fillRect(0, 0, 150, 40);
    graphics.fillRect(0, Launcher.HEIGHT - 100, Launcher.WIDTH, 100);
    graphics.setColor(Color.LIGHT_GRAY);
    graphics.fillRect(125, Launcher.HEIGHT - 100, 100, 350);
}

Das verlängerteCanvas Klasse

public abstract class Game extends Canvas implements Runnable {
private static final String TAG = "Game";

public JFrame frame;
public JPanel panel;
public boolean isApplet = false;

private boolean gameRunning = false;

BufferStrategy bufferStrategy;

private Screen screen;
private Thread renderThread;

public synchronized void start() {
    // Canvas
    setBounds(0, 0, 550, 400);
    setIgnoreRepaint(true);
    createBufferStrategy(2);
    bufferStrategy = getBufferStrategy();

    // Screen, Handlers, ETC
    screen = getStartScreen();

    // Threads
    renderThread = new Thread(this, Launcher.NAME + "_main");
    renderThread.start();
    gameRunning = true;
}

@Override
public void run() {
    long startTime = System.nanoTime();

    while (gameRunning) {
        float deltaTime = (System.nanoTime() - startTime) / 1000000000.0f;
        startTime = System.nanoTime();

        screen.update(deltaTime);

        Graphics2D graphics = (Graphics2D) bufferStrategy.getDrawGraphics();

        screen.draw(deltaTime, graphics);

        graphics.dispose();
        bufferStrategy.show();

        // FPS Counter

        // FPS Capper
    }
}
}

Was das Java 2D-Spiel-Tutorial angeht, das ich verfolge, handelt es sich um eine Web-Serie. Trotzdem lautet der Link wie folgtKlick hier. Ich habe den Code ziemlich verändert.
