    I have found a way to fix the movement, its a bit longer, but it works:

    public void keyReleased(KeyEvent e){
    int key= e.getKeyCode();

    if(key ==KeyEvent.VK_RIGHT){
    if(p.getVelX()>0)
    p.setVelX(0);
    } else if(key ==KeyEvent.VK_LEFT){
    if(p.getVelX()<0)
    p.setVelX(0);
    } else if(key ==KeyEvent.VK_DOWN){
    if(p.getVelY()>0)
    p.setVelY(0);
    } else if(key ==KeyEvent.VK_UP){
    if(p.getVelY()<0)
    p.setVelY(0);
    }
    }

    I've tried to fix some glitches with the ship control but failed… Basically when i go to an opposite direction the player freeze completely or stop for some moments. Is there a way to make the program constantly check if the keys are pressed or not, rather then just get a value the moment is pressed or released?

    I think for variable is shooting we don't have to make because if we make the test for KeyEvent.VK_SPACE in KeyReleased the problem will be resole

    Insted of fixing it like that, u could have just not do anything for VK_SPACE in the keyPressed and and type if(key==e.getkeyCode.VK_SACE){
    c.addBullet(new Bullet(p.getX(),p.getY(),this));}

    Alright, I want to ask you a question, as a person who just a week ago found this and got really interested in making a game.
    Everything is working great, thank you so much for the help. However there is one thing I want in the game that I in my unprofessional mind cannot find/understand.
    I wish for help to make it so that if you hold space, it shoots bullets constantly at a controlled pace, 10 some bullets a second was what I had in mind.
    Could you help me out with this!

    Again thank you for this awesome tutorial!

    How come it fires one quick bullet and then the full auto kick in(2:43), also why does full auto not work when the ship is going from left to right?

    I'm making a 2-d game seen from above, and I need to know how to make a sprite rotate when it is moved in a different direction.

    Ignore my question. I figured it out. It seems I added an extra line after the else if in the keyreleased KeyEvent. adding this at the end c.addBullet(new Bullet(p.getX(), p.getY(), this));
    It causes a bullet to fire when I release the space bar after firing.

    I seem to have made a mistake somewhere and I cannot identify it. When I press the space bar my ship fires but it also fires when I release the space bar. So in essence I am firing twice. Not a big issue but I would like to know what I did wrong. Any ideas?

    You can make a Background class to make it scroll, then in the tick() method you make it move up/down

    If you want random stars, then you can use this code:)
    for(int i = 0; i< 10000; i++){
    g.setColor(Color.WHITE);
    int posX = (int) (i * (Math.random()*100));
    int posY = (int) (i * (Math.random()*100));
    g.drawRect(posX,posY,1,1);
    }
