create_scene(3)

💖 create_scene(3) 💖

okay bestie, welcome to the Allegro manual ✨ this one's about create_scene, and it's giving "let's make some 3d magic happen" energy. Allegro is a game programming library, if you didn't know, and this lil function is your girl for setting up scene memory. 🎀

🌸 NAME 🌸

create_scene — allocates memory for a 3d scene. part of the Allegro game programming library. 💅

✨ SYNOPSIS ✨

#include <allegro.h>

int create_scene(int nedge, int npoly);

🦋 DESCRIPTION 🦋

so basically, this function allocates memory for a scene. the two args, nedge and npoly, are your estimates of how many edges and how many polygons you're gonna render. and listen — these are estimates, but they're also a hard cap, because you cannot get over the limit specified here. no cap, literally cannot. 🫶

here's the cute part: if you use the same values in successive calls, the space will be reused — so no new malloc(). slay, no wasted allocations, we love an efficient queen. 👑

and how much memory is that exactly? the memory allocated is a little less than 150 * (nedge + npoly) bytes. iconic math, honestly. ✨

🌈 RETURN VALUE 🌈

• returns zero on success 💖
• or a negative number if allocations fail 😭

so fr fr, always check your return value. a negative number means the allocation said "not today" and you gotta handle it. 🙈
