✨ NAME ✨

al_transform_coordinates — bestie, this is your lil' coordinate glow-up function, straight out of the Allegro 5 API manual (yes, the 3alleg5 one, iykyk 💅).

🦋 SYNOPSIS 🦋

#include <allegro5/allegro.h>

void al_transform_coordinates(const ALLEGRO_TRANSFORM *trans, float *x, float *y)

🌸 DESCRIPTION 🌸

Okay so picture this: you got a pair of coordinates, right? And you want them transformed. That's literally it. That's the whole job. This function takes a point and runs it through a transformation. Slay. 👑

Parameters, bestie, let's go one by one:

  • trans — the transformation you wanna use. Your vibe-setter, your main character. 🎀
  • x, y — pointers to the coordinates. Yes, pointers — it's not handed a copy, it gets the receipts, so they get updated in place. Not me being obsessed with pass-by-pointer fr fr. 🔥
Heads up: it takes float *, not float. So pass the address of your variables, not the values. 🙈

💜 SEE ALSO 💜

And that's the whole page, babe — this came from the Allegro reference manual, and it's the al_transform_coordinates(3alleg5) page specifically. Go forth and transform your coordinates. Periodt. 🫶✨🌸
