al_get_cur..._transform(3)

💫 al_get_cur..._transform(3) 💫

okay bestie, so this one lives in the Allegro reference manual and it's genuinely such a lil gem — short, sweet, and it does exactly one thing but does it well. let's get into it 🫶

---

✨ NAME ✨

al_get_current_inverse_transform — Allegro 5 API, the "give me the opposite of the current transform" girlie 💅

---

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

const ALLEGRO_TRANSFORM *al_get_current_inverse_transform(void)

like, no arguments, no nada. she takes nothing and gives you a pointer. iconic behaviour honestly 🎀

---

🦋 DESCRIPTION 🦋

So here's the tea: this function returns the inverse of the current transformation of the target bitmap. That's it, that's the whole vibe. Invert-y, transform-y, done. ✨

But — and this is the important part — if there is no target bitmap, this function returns NULL. like, no target bitmap, no transform, no nothing. NULL. don't come for her, she warned you 😭

This is similar to calling

al_invert_transform(al_get_current_transform())

except — and this is the slay part — the result of this function is cached. so she's doing the same math but she remembers it for you. main character energy honestly 👑

⚠️ Note: Allegro's transformation inversion functions work correctly only with 2D transformations. like fr fr, 2D only. don't try to be cute with 3D and then act surprised when things get weird. it's giving "read the note bestie" 💀

⭐ SINCE ⭐

5.1.0 — she's been around since 5.1.0, so she's basically a veteran at this point 🌈

---

and that's the whole page, bestie, you ate that 💖 this cutie comes to you straight from the Allegro reference manual — go forth and invert your transforms responsibly 🧚‍♀️🎀
