That explains it. Thanks.



All right, here's what I'm going to call the "final" version of the automatic resizing panel function. I can't really take credit for it, given it's so much shorter and elegant than my initial version(which is long because of the per video_mode checks and some sloppy, early code). Anyway, this combines eleroux's basic function with a little bit of Heelx's.

I tested it...it works. I created a black panel at 1600x1200 and set a pox_x/pos_y of 200 in the panel declaration. After switching video_modes, the panel was resized and was in the exact same spot on the screen for every resolution after calling the funcion(in this case a simple pause screen). The bad news about doing it this way is that the video memory usage is going to be large if you use a lot of large bitmaps. That 1600x1200 black panel was around 8MB when active. My fullscreen filmgrain effect(from another contribution) clocks in at around 49MB(6 1600x1200 PCX files).

I don't know enough about bitmap formats and memory consumption, so perhaps using a different format(like DDS) would reduce the mem hit.

Code:

---

panel* pnl;
var maxRes[2] = 1600, 1200; //0 = represents your maximum supported X; 1 = represents your maxiumum supported Y

function panelRefresh(panel)
{
	pnl = panel;		
	var tempScale[2];

	if(pnl)
	{
	
		tempScale[0] = pnl.scale_x; //store current panel's X scale
		tempScale[1] = pnl.scale_y; //store current panel's Y scale	

		//Scaling
		pnl.scale_x = (screen_size.x / maxRes.x);
		pnl.scale_y = (screen_size.y / maxRes.y);
		
		//Modify position:
		tempScale[0] = pnl.scale_x / tempScale[0];
		tempScale[1] = pnl.scale_y / tempScale[1];
		
		//Apply modification
                pnl.pos_x *= tempScale[0];
		pnl.pos_y *= tempScale[1]; 

		//Switch the filter flag off if the current resolution = maxRex.x
		pnl.filter = (screen_size.x != maxRes.x);				
	} 
}

function scaleAllPanels() //panel names are examples. Change to reflect your own naming convention.
{
    panelRefresh(pause);
    panelRefresh(loadMenu);
    panelRefresh(saveMenu);
    panelRefresh(gameSavingScreen);
    panelRefresh(mainMenu);
    panelRefresh(credits);
    panelRefresh(filmGrain);
    panelRefresh(blackPanel);
    ..
    ..
    ..
    ..etc..
}
