Problem / question about complex function in main game loop

[antytaon]

Greetings from Poland!
I got FPS problem. Look at this code.

Function outside:
//
[/code]

In main game loop:

Code: [Select]


//


In this situation i got like 14-15 FPS.
When I comment function in main game loop i got 60 FPS.
When I comment content of DrawPlayingArea function i got like 15 FPS.
Do the function uses too many arguments or arguments too 'heavy'?
Thanks in advance for any help.

Code: [Select]

sf::Image G, sf::Image T1, sf::Image MI, sf::Image SMI
Use references, otherwise you'll copy the whole images (which take probably several KB or MB of memory) every time you call the function!

Code: [Select]

const sf::Image& G, const sf::Image& T1, const sf::Image& MI, const sf::Image& SMI
And instead of copying the visible area to a new image, why don't you simply use the SubRect property of the sprite?
