the widescreen trick (aspect) #208893 05/30/08 13:29 05/30/08 13:29

mercuryus OP Unregistered M	User of widescreen monitors see a distorted game if the programmer did not offers a necessary resolution. If you want to offer at least the right aspects for all types of monitors you can use the following code to set the right camera aspect. Code: var gv_scr_width; var gv_scr_height; //... // before resolution change gv_scr_width=sys_metrics(0); gv_scr_height=sys_metrics(1); // set the resolution here // ... // set aspect camera.aspect=(screen_size.y/screen_size.x)/(gv_scr_height/gv_scr_width);

I'm currently still working with A6 - that's why I didn't find sys_metrics in the manual! http://www.puppenheim.org/ http://www.wuerfels-welt.de Old Game Tutorial: http://www.puppenheim.org/MITutorial.zip Free Game Editor: http://puppenheim.org/AlienalsWeihnachtsmann.zip http://www.puppenheim.org/blender_starting_main_settings.txt

Here's my code: desktopWidth = sys_metrics(0); desktopHeight = sys_metrics(1); video_set(desktopWidth,desktopHeight,0,1); camera.aspect=(screen_size.y/screen_size.x)/(desktopHeight/desktopWidth); BTW, doesn't it same between screen_size.y vs desktopHeight?

mercuryus OP Unregistered M	sys_metrics(0) and sys_metrics(1) represents the current monitor resolution (before the Engine starts). video_set sets the engine window size. You make the engine window the same size like the monitor size (ignoring the aspects) because you set the size BEFORE getting the aspect ratio. Afterwards screen_size.y of cause is equal desktopHeight.

Yeah!! I found my solution and lets share

Note: I put this at the first line of main( ) function.

What this code do? Change the resolution to the user native resolution IF, the screen wide up to 1680. If the user use bigger screen, change the resolution into their respective category. If the user use "strange" resolution, just make it window mode to be on the safe side.

The reason I limit the resolution for super big monitor is because they'll have huge advantage. Imagine you make a side scrolling game, of course wider screen will see the enemy sooner and have "more time" to avoid enemy attack.

Code:

desktopWidth = sys_metrics(0);
desktopHeight = sys_metrics(1);

if (desktopWidth<1681) video_set(desktopWidth,desktopHeight,0,1);
else
{
	if 	(desktopWidth/4  == desktopHeight/3)	//Classic
	{
		video_set(1024,768,0,1);
		desktopWidth = 1024;
		desktopHeight = 768;
	}
	else if (desktopWidth/15 == desktopHeight/9)	//BrightView
	{
		video_set(1280,768,0,1);
		desktopWidth = 1280;
		desktopHeight = 768;
	}
	else if (desktopWidth/5  == desktopHeight/4)	//SXGA
	{
		video_set(1280,1024,0,1);
		desktopWidth = 1280;
		desktopHeight = 1024;
	}
	else if (desktopWidth/16 == desktopHeight/10)	//WSXGA+
	{
		video_set(1680,1050,0,1);
		desktopWidth = 1680;
		desktopHeight = 1050;	
	}
	else						//Window Mode
	{
		video_mode = 8;
		video_window(nullvector,nullvector,1,NULL);
		wait(1);	// must put this. not sure the reason
		desktopWidth = screen_size.x;
		desktopHeight = screen_size.y;
	}
}

float fAspect = desktopWidth/desktopHeight;
camera.aspect = fAspect / 1.333333; // Not sure why have to hard code
