Hey there, I know this is C++ Allegro coding but I know the majority here are all very experienced coders and this is probably a simple fix so even if you have no knowledge of allegro you could probably fix it. Basically I'm making a pong game, I want it so that when the main menu image comes up (picture.bmp) if the user presses the ESC key at any time the program will close. Currently I have the code as seen below however when I run that it goes terribly wrong and constantly opens new versions of the game up over and over and over. (I imagine this is because it is noticing that the ESC key is not pressed and therefore continues to carry out the creation of the image). Any help would be highly appreciated!
Cheers
int main( void )
{
while(!key[KEY_ESC])
{
BITMAP *bmp; //Pointer to the bitmap
allegro_init(); //Initializes Allegro
install_keyboard(); //Enables the ability for allegro to receive keyboard input
set_color_depth( 32 ); //Setting the colour depth to 16 bit
set_gfx_mode( GFX_AUTODETECT_WINDOWED, 640, 480, 0, 0 ); //Setting the graphics mode
set_window_close_button( 1 );
set_window_title ("PONG!");
bmp = load_bitmap( "picture.bmp", NULL ); //Loads the bitmap file
blit( bmp, screen, 0, 0, 0, 0, bmp->w, bmp->h ); //Draw the bitmap
}
destroy_bitmap( bmp ); //Frees the memory allocated to bmp when closing the program
return 0;
}
END_OF_MAIN() //Allegro specific end main function
int main( void )
{
BITMAP *bmp; //Pointer to the bitmap
allegro_init(); //Initializes Allegro
install_keyboard(); //Enables the ability for allegro to receive keyboard input
set_color_depth( 32 ); //Setting the colour depth to 16 bit
set_gfx_mode( GFX_AUTODETECT_WINDOWED, 640, 480, 0, 0 ); //Setting the graphics mode
set_window_close_button( 1 );
set_window_title ("PONG!");
bmp = load_bitmap( "picture.bmp", NULL ); //Loads the bitmap file
blit( bmp, screen, 0, 0, 0, 0, bmp->w, bmp->h ); //Draw the bitmap
while(!key[KEY_ESC]){}
destroy_bitmap( bmp ); //Frees the memory allocated to bmp when closing the program
return 0;
}
END_OF_MAIN() //Allegro specific end main function
I think you should somewhat re-think what went wrong in your code.
Hint: You blitted the image for each iteration.
I don't know the allegro library, but i think there's supposed to be a function to update the key pointer.
