get_x_rotate_matrix(3alleg4)

💖 NAME 💖

get_x_rotate_matrix, get_x_rotate_matrix_f — bestie, these two are here to construct X axis rotation matrices. It's giving Allegro game programming library energy, as always. 🎀

✨ SYNOPSIS ✨

#include <allegro.h>

void get_x_rotate_matrix(MATRIX *m, fixed r);

void get_x_rotate_matrix_f(MATRIX_f *m, float r);

Two lil functions, same job, different float flavor. Pick your fighter. 💅

🌀 DESCRIPTION 🌀

okay so listen. Both of these cuties construct X axis rotation matrices and tuck them right into m. That's the whole vibe. 🫶

Then, when you apply one of those matrices to a point, it rotates that point about the X axis by the angle you handed over — and yes bestie, that angle is given in binary, 256 degrees to a circle format. Not your regular degrees. Not radians. The Allegro way. iykyk. 🔥

So you're literally just saying "spin this thing around the X axis, this much," and the matrix does the rest. main character energy fr fr. 💀✨

heads up: the angle format is binary, 256 degrees to a circle — don't come in here with regular degrees, she will not understand you. 🎀
