Hi folks,
I'm trying to make a small game about being a drug dealer, with a 10x8 grid JPanel. On top of that i have another 10x8 grid JPanel as glassPane for the player icon.
I have all the properties of the player in a player object class with getter and setter methods for fx his X and Y position in the grid.
When i set up his X and Y position myself everything works fine and he is painted the right place.
My problem is when my keyPressed method updates his X,Y position and repaint the glass pane everything goes wrong. At first key press (no matter which) he disappers, and i have no ideer why.
Something about the repainting of the glassPane goes wrong, but what?
Any help or hint would be greatly appreciated.
Here is my display code:
