NAME exflame – How to write directly to video memory improving performance. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exflame DESCRIPTION This program demonstrates how to write directly to video memory. It implements a simple fire effect, first by calling getpixel() and putpixel(), then by accessing video memory directly a byte at a time,…

NAME exfixed – Using fixed point maths. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exfixed DESCRIPTION This program demonstrates how to use fixed point numbers, which are signed 32-bit integers storing the integer part in the upper 16 bits and the decimal part in the 16 lower bits. This example also uses the unusual…

NAME exexedat – Appending datafiles onto your executable. Allegro game programming library. SYNOPSIS #include <allegro.h> Example exexedat DESCRIPTION This program demonstrates how to access the contents of an Allegro datafile (created by the grabber utility) linked to the executable by the exedat tool. It is basically the exdata example with minor modifications. You may ask:…
