Well, the code above does not work. When I start it up it says: |

Are you getting a runtime error from windows? Is it a segfault? You need to pay your elves more!

You're loading and creating bitmaps on global scope. Things on global scope happen before normal program execution. Allegro doesn't like that. |

I don't want to have to declare them in every single function or pass them to each one... What can I do? |

Declare them globally, but initialize them, i.e. create/load bitmaps, in a function after you initialize allegro correctly.

How might one go about doing that? I only know how to do it the way above. Is it like this?: A = load_bitmap("sprites/CCC.bmp", NULL);

BITMAP* bmp; void load_bitmaps() { bmp = load_bitmap("blah.bmp", NULL); } int main() { init_allegro_and_whatever(); load_bitmaps(); do_whatever_you_like_now(); return 0; } Of course, you should always check for return values, i.e. did you succeed in loading the bitmap.

OH, so I basically declare them globally and add their values or whatever you may call it in a function. Thanks a ton! *EDIT* 1#include <allegro.h>

178 A = load_bitmap("sprites/AAA.bmp", NULL);
179 B = load_bitmap("sprites/BBB.bmp", NULL);
180 C = load_bitmap("sprites/CCC.bmp", NULL);
181 }
I did all of it and even made a few changes. It still crashes, but now the allegro window comes up, not just the console. |

Arvidsson said: Of course, you should always check for return values, i.e. did you succeed in loading the bitmap. Also, instead of having 26 variable names, have you considered having an array of 26 bitmaps? BITMAP *letter[26]; // Takes up much less space.

Sorry but the help you gave does not help because it is crashing before even the sqr bitmaps show up, the whole screen is just black, thus I can't tell if the text has popped up or not. |

... I realise that the crash is before the bitmaps show up. If the bitmaps had already showed up then it would be pointless to check if they had loaded, wouldn't it? If you have having trouble seeing the output from stderr, here are a few (independent) options:

Found the problem. Was drawing the sqr sprites before they had been given their sprites. Thanks for the help. |
