al_map_rgba_f(3alleg5)
π al_map_rgba_f β Allegro 5 API π
okay bestie, gather round, because this little function is from the allegro5 manual and it's literally the glow-up version of making colors. no cap.
β¨ SYNOPSIS β¨
#include <allegro5/allegro.h>
ALLEGRO_COLOR al_map_rgba_f(float r, float g, float b, float a)
like, that's it. four floats walk into a bar and one ALLEGRO_COLOR walks out. iconic behavior tbh π
πΈ DESCRIPTION πΈ
so what this does is it takes r, g, b, a β and those babies range from 0.0f to 1.0f β and converts them into an ALLEGRO_COLOR(3alleg5). that's the whole job. she's simple, she's reliable, she eats every time π
the f in the name? that's the float vibe. you're working in 0.0f-to-1.0f land instead of the 0-to-255 integer land, so if you're the type who thinks in percentages and decimals, this is your main character function π
β¨ fun fact that's also extremely important: this function can be called before Allegro is initialized. yes, fr fr. you don't have to wait for the whole engine to wake up. she's ready whenever you are. lowkey the most convenient thing about her.
so like, no setup required, no init gatekeeping, just colors. we love a low-maintenance queen π¦

and that's the whole page, bestie. go forth and make pretty pixels. this was the Allegro reference manual, page al_map_rgba_f(3alleg5), and yes she really is that girl. mwah πβ¨π
