Takes keyboard input only after a repaint about snake_game HOT 5 OPEN

If you are referring to your JApplet version in the 'master' branch you are missing the call to setFocusable(true) for the JApplet. Add that to your init function and that problem will be solved.

I do have to warn you though, the way you are initializing and starting some pieces of the program is going to cause problems if you hope for the "start", "stop", and "restart" buttons in the menu to ever work properly. Here is a quick overview. JApplet's are almost extinct but the concept is worth understanding.

Good luck!

Thanks for your suggestion. I will look into it and improve my code for the JApplet version.

But i was referring to JFrame version of the application in which I am facing this problem.
It would be nice if you could help me with the JFrame version of the application.

I am now working on JFrame as I heard Applets are a thing of past and that they require signing and other security certificates.

Remove this from the prepareGame method

        drawpanel.setFocusable(true);
        keyboardinputlistener k = new keyboardinputlistener();
        screen.addKeyListener(k);
        drawpanel.addKeyListener(k);

Add this to init

        frame.addKeyListener(new keyboardinputlistener());
        frame.setFocusable(true);
        frame.requestFocus();

Thanks a lot
You solved my problem 👍

Can you explain me whats the difference in applying KeyboardInputListener to JPanel than to applying to Frame ?

I'm not completely sure, I think it is a focus issue.
