I want a centred panel, idependently of screen ratio.
I tried this:

Code:

var panel_pos_x=screen_size.x/2-50;
	var panel_pos_y=screen_size.y/2-25;
	PANEL* splash_panel = pan_create
	("
	pos_x=panel_pos_x;
	pos_y=panel_pos_y;
	bmap=logo16.bmp;",1);
	set(splash_panel,SHOW);
	wait(-5);
	ptr_remove(* splash_panel);

But, it shows bitmap on left upper corner.

P.S. Please any moderator if it is a engine bug move this thread for proper forum.

Thanks in advance

The problem is that you're using global variables, right? Now for some reason (someone with more experience may tell you why) you can't define global variables to use screen_size as a value. So you have two options:

-Use local variables
-Define variable later inside of a function

Then it'll work just fine

It can't be a global variable, because 'screen_size' is not known at compile time, only at runtime.

Also it seems only constants can be passed to pos_x/pos_y, so that might also be a problem, although i'm not sure about Panels defined at runtime.

Finally 'ptr_remove(* splash_panel);' shouldn't compile. as 'ptr_remove' wants a pointer and '*splash_panel' is a pointer-to-a-pointer.

try it with brackets
var panel_pos_x=(screen_size.x/2)-50;
var panel_pos_y=(screen_size.y/2)-25;
perhaps it will work
Hope that helps
here is something out of the manual with centered Panel (:

// startup with 300x300 window resolution
function main()
{
screen_size.x = 300; screen_size.y = 300;
...}

// place panel in the center of the screen
function center_panel(PANEL* panel)
{
panel.pos_x = (screen_size.x - bmap_width(panel.bmap))/2;
panel.pos_y = (screen_size.y - bmap_height(panel.bmap))/2;
}
