Hello, i am trying to move an Image inside panel controle.
I have background image:
load event:
panel1.BackgroundImage = img;
and Image:
paint event:
e.Graphics.DrawImage(img_player, new Point(0, 0));

How can i send int variable from key_down event to paint event and add code like this one
e.Graphics.DrawImage(img_player, new Point(0+x, 0+y)); how can i send x and y variable?

C#

private void Form1_KeyDown(object sender, KeyEventArgs e)
       {
           if (e.KeyData == Keys.Up)
           {
               int x = 10;
               int y = 0;

           }
and etc key.down,key.left,key.right same thing just x and y will be different..

img and img_player are global:
Image img = Image.FromFile(@"D:\C#\Lavirint\Lavirint\images\map1.png");
Image img_player = Image.FromFile(@"D:\C#\Lavirint\Lavirint\images\player.png");

Solution 1

Use X and Y as member of your class update them in the KeyDown event and invalidate the control that paint the image just after.

C#

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
  if(e.KeyData == Keys.Up)
  {
    x=10;
    y=0;
    imgCtrl.Invalidate();
  }
}
private void imgCtrl_OnPaint(object sender, PaintEventArgs e)
{
  e.Graphics.DrawImage(img_player, new Point(x,y));
}

This code should be adapt to your purpose.

It's good enough to illustrate the idea, but coding style is the way off, and using of hard-coded coordinates 10, 0 is not practically useful. If OP has brain, it can be reworked in something working. I voted 4.
