identity_quat(3alleg4)

💖 identity_quat — the Allegro manual, bestie edition 💖

okay so this is identity_quat from the Allegro game programming library, living in section 3alleg4 of the manual. it's a tiny page. it's a powerful page. let's get into it 🫶

✨ NAME ✨

identity_quat — a global variable holding the identity quaternion. part of the Allegro game programming library, bestie.

🌸 SYNOPSIS 🌸

the way you just include the header and it's right there:

#include <allegro.h>

extern QUAT identity_quat;

that's it. that's the whole vibe. no function call, no setup, she's just there for you. 💅

🦋 DESCRIPTION 🦋

so identity_quat is a global variable and she contains the 'do nothing' identity quaternion. QUAT type, obviously, iykyk.

what does "do nothing" mean? it means she's the quaternion equivalent of multiplying by 1. the neutral one. the one who minds her own business. ✨

the important bit, and i need you to remember this fr fr:

• multiplying by the identity quaternion has no effect. none. zero. nothing changes. she is the chillest girl in the rotation game — you multiply by her and your orientation is exactly the same as before. main character energy of "i'm not gonna change you, you're perfect as you are" 😭💖

so if you ever need a starting point for a quaternion, or a value that just doesn't do anything, this is her. iconic. periodt.

lowkey the best variable in the whole library because she literally cannot break anything. no cap. 🎀

🧚 a lil sign-off 🧚

this page came from Allegro, version 4.4.3, and it's filed under identity_quat(3alleg4) in the manual — so when you cite her, cite her right. slay, bye bestie 💜🌈⭐
