Wie man ein Applet davon abhält zu blinken?

Question

Ich habe versucht, eines meiner Spiele in ein Applet zu konvertieren, aber da es das erste Mal ist, dass ich ein Applet benutze, habe ich ein Problem bekommen. Grundsätzlich, wenn ich das Spiel öffne, fängt der Bildschirm an zu blinken. Ich bin mir ziemlich sicher, dass es daran liegt, keine BufferStrategy zu haben, aber wenn ich versuche, einen wie "BufferStrategy bg = this.getBufferStrategy()" zu erstellen, funktioniert es nicht. Kann jemand helfen?

package main; 

import java.awt.Color; 
import java.awt.Graphics; 

import javax.swing.JApplet; 

import Handling.Handler; 
import Other.HUD; 
import Other.KeyInput; 


public class Game extends JApplet implements Runnable{ 

    private static final long serialVersionUID = 9021342660060318393L; 

    public static final int WIDTH = 640; 
    public static final int HEIGHT = WIDTH/12 * 9; 

    private Thread thread; 
    private boolean running = false; 

    private Handler handler; 
    private HUD hud; 
    private Spawner spawner; 
    private Menu menu; 

    public enum STATE{ 
     Menu(), 
     Help(), 
     Settings(), 
     DeathScreen(), 
     Game(); 
    }; 

    public enum DIFFICULTY{ 
     Easy(), 
     Mediuм(), 
     Hard(); 
    }; 

    public STATE GameState = STATE.Menu; 
    public DIFFICULTY difficulty = DIFFICULTY.Easy; 







    private void tick(){ 
     handler.tick(); 
     if(GameState == STATE.Game){ 
      hud.tick(); 
      spawner.tick(); 
     }else if(GameState == STATE.Menu){ 
      menu.tick(); 
     } 
    } 

    public void paint(Graphics g){ 

     //DRAW HERE 
     g.setColor(Color.black); 
     g.fillRect(0, 0, WIDTH, HEIGHT); 

     handler.paint(g); 

     if(GameState == STATE.Game){ 
      hud.paint(g); 
     }else if(GameState == STATE.Menu || GameState == STATE.Help || GameState == STATE.Settings || GameState == STATE.DeathScreen){ 
      menu.paint(g); 
     }

     hud = new HUD(); 
     spawner = new Spawner(handler, hud, this); 
    } 

    public void start(){ 
     thread = new Thread(this); 
     thread.start(); 
     running = true; 
    } 

    public void destroy(){} 

    public void stop(){ 
     try { 
      System.exit(1); 
      thread.join(); 
      running = false; 
     } catch (InterruptedException e) { 
      e.printStackTrace(); 
     } 

    } 

    public void run() { 
     this.requestFocus(); 
     long LastTime = System.nanoTime(); 
     double amountOfTicks = 60.0; 
     double ns = 1000000000/amountOfTicks; 
     double delta = 0; 
     long timer = System.currentTimeMillis(); 
     int frames = 0; 
     while(running){ 
      long now = System.nanoTime(); 
      delta += (now - LastTime)/ns; 
      LastTime = now; 
      while(delta >= 1){ 
       tick(); 
       repaint(); 
       delta--; 
      } 
      frames++; 

      if(System.currentTimeMillis() - timer > 1000){ 
       timer += 1000; 
       System.out.println("FPS: " + frames); 
       frames = 0; 
      } 
      try { 
       thread.sleep(20); 
      } catch (InterruptedException e) { 
       e.printStackTrace(); 
      } 
     } 
     stop(); 
    } 

}

Statt Repaint() aufgerufen wird, versuchen

paint(getGraphics()). 

Eine andere Sache zu nennen, fügen Sie diese Methode, um das Applet:

public void update(java.awt.Graphics g) {}
