fullscreen on macos@macintel

i have a problem... when i compile my game, i impose the graphic mode at 320x240px@32bpp... on windows platform it works well (the screen res change to fullscreen 320x240), but on OSX 10.4.8 (running on a MacBook Intel CoreDuo T2500 with a GMA950) the resolution doesn't switch. the fullscreen mode start, but the res is always 1280x800 so the game appears an 1/4 on the bottom side left (it fill a 320x240 area), even if i try @16bpp. to initialize the graphic mode i use these settings:

Graphics 320, 240, 32

maybe on OSX i must initialize with others settings? or maybe the GMA950 does not support these settings?

some ideas? :)

p.s. i'm sorry for my english :P

Quite possible:

Of course, they could have just ommited the 'ancient' resolutions from the list since few people use them anymore.

Tip: Check the CountGraphicsModes and GetGraphicsMode commands, with which you can get a list of all resolutions supported by the computer. Does it list 320x240 in there?

thanks xlsior!!!
yes the problem is that the 320x240 is not supported ! :(

i'll make my game for osx run in a window!

You'd be lucky to find a mac these days that supports anything below 640x480. Even my 10 year old ibook is 640x480 minimum.

320x240 is going to be a very small window, as a user is likely to be using the native resolution of their display, i.e. 1280x800 in the above case - that's roughly 1/16th of the total area of the display!

The best all-round solution would be to use 640x480 and double everything up.

If you go to the BlitzWiki, there's a function there called VirtualGraphics which you can use to run your game in any resolution, but maintaining the resolution you want.

It's not 100% perfect if you want pixel perfection, but at any rate it could be a useful starter.

You just need to set up a 640x480 screen with a projection matrix with 320 and 240 as some of the values so everything is automatically doubled.

thanks! guys!!!
my game is a old style remake (...) and is very low res...

i think to double all the gfx with the function from blitz wiki "VirtualGraphics"

Thanks.

Just be sure to note that if you're reading any mouse input or setting up any viewports, you'll need to double up as well.

Ok. thanks Fry!
