get_scaling_matrix(3alleg4)

💖 get_scaling_matrix — bestie edition 💖

okay so this is a page from the Allegro manual, and it's about making your stuff get bigger or smaller ✨ literally the glow-up function.

🌸 NAME 🌸

get_scaling_matrix, get_scaling_matrix_f — they construct a scaling matrix, no cap. Part of the Allegro game programming library 🎀

✨ SYNOPSIS ✨

#include <allegro.h>

void get_scaling_matrix(MATRIX *m, fixed x, fixed y, fixed z);

void get_scaling_matrix_f(MATRIX_f *m, float x, float y, float z);

🦋 DESCRIPTION 🦋

So basically, this function builds a scaling matrix and tucks it all cozy into m. 🫶

When you apply it to a point (px, py, pz), the matrix hands you back the point (px*x, py*y, pz*z). In other words — and I need you to hear me on this — it stretches or shrinks things 💅

That's it. That's the whole vibe. Scale = stretch or shrink. Slay.
