Yeah, :D I made it work!


if(e.getKeyCode() == 38)
{
y = player1.getY();
System.out.println("Pressed");
// y = 200;
...

Because the Y value is the components Y - value. When I change the Y value
int y = 100; the component is changing it's position. Then I just thought it sounded reasonable that it would also change...

Because I change the value of y:
y = y + 10;

Or?? wouldn't that work?

I tried using the .setFocusable(true) in "public Spelplan". I also kept the printline "Pressed" inside the if-statement. Now it says "Pressed", but the component does not move.

Why won't my "player1" move???

Hi,

I use this to draw up an image file on the JFrame. But instead of giving x and y pos I want the img to go with the flowlayout like the rest of my code (JButtons and such). How do I do?
