I'm very interested in game programming and I'm taking my first steps alone. So I installed allegro. Although Dev-C++ didn't work, Code::Blocks compiled successfully. I started out with this basic program:
#include <allegro.h>
int main(){
    allegro_init();
    install_keyboard();
    set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0);
    readkey();
    return 0;
}   
END_OF_MAIN();
The problem comes in when I try to run it. It opens the little window as always, but rapidly blacks out my whole screen. I press any key and it takes me back to the little window telling me that it finished, which means the program worked. But I try any other program with allegro, like:
#include <allegro.h>
int x = 10;
int y = 10;
int main(){
    allegro_init();
    install_keyboard();
    set_gfx_mode( GFX_AUTODETECT, 640, 480, 0, 0);
    while ( !key[KEY_ESC] ){
        clear_keybuf();
        acquire_screen();
        textout_ex( screen, font, " ", x, y, makecol( 0, 0, 0), makecol( 0, 0, 0) );
        if (key[KEY_UP]) --y;        
        else if (key[KEY_DOWN]) ++y;    
        else if (key[KEY_RIGHT]) ++x;
        else if (key[KEY_LEFT]) --x;
        textout_ex( screen, font, "@", x, y, makecol( 255, 0, 0), makecol( 0, 0, 0) );
        release_screen();
        rest(50);
    }    
    return 0;
}   
END_OF_MAIN();
And the same thing happens over and over again! Is there something I'm doing wrong?
