✨ NAME ✨

al_set_shader_matrix — Allegro 5 API 🦋

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

bool al_set_shader_matrix(const char *name,
   const ALLEGRO_TRANSFORM *matrix)

---

💅 DESCRIPTION 💅

so basically, this function sets a matrix uniform of the current target bitmap's shader. like, you're sliding a whole transformation matrix into the shader's uniform slot and it's giving main character energy. ✨

it returns true on success. but if things don't go your way, it returns false — for example, if the uniform by that name does not exist in the shader. 💀 not the shader ghosting your uniform name, but okay.
