Re: [Dev-C++] Help with Game Problem

[Robson B. <rob...@su...>]

Have you tried allegro game library (compatible with Dev-C++)? With allegro
you have some great stuff to make games. Try www.talula.demon.co.uk and
click the link to allegro library.

Below a brief example of how to set interrupt handlers to manage game timing
with allegro and c++. It makes a very stable timing:

Hope it helps!


// this boolean variable prevents from jumping for the next game step before
the time expected;
volatile bool doInterrupt;



void refresh()
{
    doInterrupt = false;
}
END_OF_FUNCTION(refresh)



void doGame()
{
    do {
        doInterrupt = true;      //sets another step

        //game stuff

        while(doInterrupt);      //while doInterrup is true, the game does
not advance for the next step.
                                          //this interval is set by the
argument in the Install_Int funtion (in miliseconds).

    } while(!key[KEY_ESC]);

}



// this function sets an interrupt handler calling function 'refresh()'
every 50ms.
Install_int(refresh, 50);
