Ich bin gerade dabei tetris zu programmieren (Anfangsphase) habe allerdings ein Problem der KeyListener funktioniert nicht und ich weiß nicht warum bitte um Hilfe 🙂
Java:
public class GameGUI extends javax.swing.JFrame implements Runnable, KeyListener {
int gamefield[][] = new int[11][21];
Game game;
Thread t;
int x = 0;
int y = 10;
int gf_x=0;
int gf_y=0;
Graphics2D g;
/**
* Creates new form GameGUI
*/
public GameGUI() {
initComponents();
try {
UIManager.setLookAndFeel(new NimbusLookAndFeel());
SwingUtilities.updateComponentTreeUI(this);
} catch (UnsupportedLookAndFeelException ex) {
}
this.addKeyListener(this);
}
