Hey,
Ich arbeite seit ein paar Tagen an einem Java 16 Spiel.
Bei der GameLoop, die ich von einem YouTuber habe, komme ich bei der Render Methode nicht weiter, da ich nicht so richtig verstehe wie ich diese füllen muss. Die Update Methode und die GameLoop an sich verstehe ich aber.
Ich habe mal die Gui Klasse, das Label mit dem ich zeichne und die GameLoop angehangen.
[CODE lang="java" title="Gui Klasse"]package Graphic;
import javax.swing.JFrame;
public class Gui {
public Gui() {
Main.Variables.jf1 = new JFrame();
Main.Variables.jf1.setSize(Main.Variables.screenwidth, Main.Variables.screenhight);
Main.Variables.jf1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Main.Variables.jf1.setLocationRelativeTo(null);
Main.Variables.jf1.setLayout(null);
Main.Variables.jf1.setTitle("Asteroids");
Main.Variables.jf1.setResizable(false);

Main.Variables.jf1.addMouseListener(new InputHandler.MouseHandler());
Main.Variables.jf1.addMouseMotionListener(new InputHandler.MouseHandler());

Main.Variables.lb1 = new Label();
Main.Variables.lb1.setBounds(0, 0, Main.Variables.screenwidth, Main.Variables.screenhight);
Main.Variables.lb1.setVisible(true);
