Lol I don't know what the hell you are doing but the following example works for me:
Code:

---

bmap bild01_map = <bild01.tga>;
bmap bild02_map = <bild02.tga>;

function change_image();

panel panel1
{
	pos_x = 10;
	pos_y = 10;
	bmap = bild01_map;
	flags = visible;
	on_click = change_image;
}

function change_image()
{
	if(panel1.bmap == bild01_map)
	{
		panel1.bmap = bild02_map;
	}
	else
	{
		panel1.bmap = bild01_map;
	}
}

Mouse_mode is set to 2 (two).

alrighty i fixed it so no errors come up (same code as you have there) but still panel doesnt change :S

Please post the code.
Btw: do you have mouse_mode set to something bigger than zero (e.g. 2) ?
And you do have a mouse_map and a function which handles the mouse_pos.x/y ?
I mean otherwise you couldn't click on it

lol i dont think so umm heres the code again

if i need the mouse mode and mouse map where do i place the code ?

LOL you don't have any mouse code?
How are the buttons supposed to work then anyway?

uhm .. ok just insert this code snippet at the beginning of your code:
Code:

---

bmap arrow_map = <arrow.pcx>; //or whatever your arrow file is

---

then place this where your functions are/will be:
Code:

---

function set_mouse(_mode)
{
  mouse_mode = _mode;
  mouse_map = arrow_map;
  while(mouse_mode > 0)
  {
    mouse_pos.x = pointer.x;
    mouse_pos.y = pointer.y;
    wait(1);
  }
  mouse_map = null;
}

---

And add this at the end of your main function (which loads the level):
Code:

---

set_mouse(2);

---

I guess thats it.

YAY that works

just one last thing not too much trouble hopefully

when i click it it stays on the sitbutton bmap... how would i make it so that when i click it it goes to sitbutton then back to sit....i hope that wasnt too confusing lol

just edit the change function a bit:
Code:

---

function change_sitbtn()
{
  panel1.bmap = sitbutton;
  wait(-1); //wait 1 second
  panel1.bmap = sit;
}

---

EDIT:
another way:
use the button element:
Code:

---

panel panel1
{
  pos_x = ___
  pos_y = ___
  layer = ___
  button = 0,0,sitbutton,sit,sit,null,null,null;
  flags = visible;
}

---

yep thats cool

thanks for that thunder... hope it wasnt too much of a hassle
