al_compose_transform(3)

🌸 NAME 🌸

okay so bestie, this is al_compose_transform(3) from the Library Functions Manual, and it's literally the Allegro 5 API function for composing (combining) two transformations by matrix multiplication 💅✨

---

🦋 SYNOPSIS 🦋

#include <allegro5/allegro.h>

void al_compose_transform(ALLEGRO_TRANSFORM *trans, const ALLEGRO_TRANSFORM *other)

---

💖 DESCRIPTION 💖

Bestie, the vibe is simple: you take two transformations and combine them with a matrix multiplication. The manual writes it exactly like this:

trans := trans other

Now pay attention, because this is the order tea ☕: the order of matrix multiplications is important. The effect of applying the combined transform will be as if you first apply trans and then apply other — and not the other way around. No cap, do not flip it 🙈🔥

🎀 Parameters 🎀

• trans — transformation to alter 🛠️
• other — transformation used to transform trans ✨

• al_rotate_transform(3)
• al_scale_transform(3)

that's the whole page, bestie 🫶 source/version is the Allegro reference manual, the page is al_compose_transform(3), and there's no date listed on the original footer — so no made-up date from me 💖🎀
