exstars(3alleg4)

💫 exstars — the Allegro manual, but make it a group chat 💫

okay bestie, welcome to the Allegro manual page for exstars, and I need you to know right now: this one is so fun. it's a whole little demo, it lives in the Allegro game programming library, and it's giving main character energy from the very first frame. let's go 🫶

✨ NAME ✨

exstars — a 3d starfield and a lightsourced spaceship. it's part of the Allegro game programming library, and yes, it ate. 💅

🌈 SYNOPSIS 🌈

#include <allegro.h>

Example exstars

that's it. that's the whole vibe. one include and you're in. 🦋

🎀 DESCRIPTION 🎀

okay so here's the tea: this program draws a 3D star field that is depth-cued — meaning the stars fade with distance, which is literally the cutest little depth effect you've ever seen — plus a polygon starship that you can actually control with the keyboard cursor keys. 🚀

and how does it do all that? using the Allegro math functions. no cap. matrices, fixed point, projections, the whole buffet. it's not just pretty, it's mathematically pretty. periodt. 💖

ngl, this is the demo you open when you want to feel like a genius and also like you're flying a spaceship. both. at once. iconic.
