My KeyListener and the methods work, but they don't do anything. When I run the code and I try to use the arrow keys, nothing happens. I also have another problem. I'm making a game and I already did the map, but when I put the map in, the map has priority and covers my character. How would I go about fixing these?
This is the JFrame Package.
package MyGamePKG;
import java.awt.BorderLayout;
public class GameJFrame extends JFrame {
private JPanel contentPane;
private int x,y,x_vel,y_vel;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
GameJFrame frame = new GameJFrame();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the frame.
*/
public GameJFrame() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 720, 520);
contentPane = new JPanel();
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
GameJPanel Jpanel = new GameJPanel();
Jpanel.setBounds(0, 0, 720, 480);
contentPane.add(Jpanel);
Jpanel.setLayout(null);
}
}
