Code works but nothing shows

[Hagelslag]

I'm fooling around with java and am trying to make a simple pacman game.
but after changing some code(i dont know when) panman is invisible.
i cant find out why and have tried everything to my knowledge, i hope someone on this forum can tell me what im doing wrong.

		setTitle( "pacman" );
		setLocation( 200, 100 );
		setBackground(Color.RED);
		spelPaneel hoofdPaneel = new spelPaneel();
		knoppenBalkPaneel knoppenPaneel = new knoppenBalkPaneel(hoofdPaneel);//knoppenBalkPaneel are the four buttons to move with
		add(hoofdPaneel, BorderLayout.CENTER);

Where in that code are you drawing the pacman?
Where are you calling the drawPac method?

[Hagelslag]

Thank you!
i had deletet the drawPac in the paincomponent in spelPaneel!
put pacs[0].drawPac(g); in there and now it works
