Can anyone please explain too me how a splitscreen game works. //Necron

Well I never exactly done a split screen game, but I have done a multimonitor game... which is more or less the same I guess

Basically it''s just like a normal one player game, you do your game logic and stuff then when rendering you render one screen for the 1st player and 1 screen for the 2nd... if it''s a 2 player game that is...

Not exactly a good description... i guess the best thing for you to do (if you never seen a split screen game b4) would be to look at the N64 Quake... and... there was the PS game which I saw... 3D shooter split screen also..

I have seen plenty of splitscreen games, but I wonder how to program it.

Do you have to show and update the images on 2 places of the screen?

You don''t need to update and show the image on 2 places of the screen.
What you could do is compose the image in an offscreen surface and then blit this surface to the screen. This is definitely much faster than directly updating all individual images on the screen.
