color_map(3)

💖 color_map(3) 💖

ok so bestie, we're in the Allegro manual and this is the Allegro game programming library tea. sit down, grab a strawberry, let's talk about color_map. 🍓

✨ SYNOPSIS ✨

#include <allegro.h>

extern COLOR_MAP *color_map;

🌸 DESCRIPTION 🌸

So color_map is a global pointer to the color mapping table. that's it, that's the whole vibe. 🦋

but here's the part where you gotta lock in: you must allocate your own COLOR_MAP, either statically or dynamically, and set color_map to point at it before you use any translucent or lit drawing functions in a 256-color video mode. not "whenever", not "later", not "oops I forgot" — before. periodt. 💅

like, here's the example, bestie, look how easy:

color_map = malloc(sizeof(COLOR_MAP));
if (!color_map)
   abort_on_error("Not enough memory for color map!");

see? allocate, check it didn't fail, done. the if (!color_map) is you doing a little vibe check on your malloc and calling abort_on_error if it came back empty. iconic behavior honestly. 😭✨
