al_use_shader(3alleg5)

✨ al_use_shader ✨

ok so bestie, this one's from the Allegro 5 API — aka the Allegro reference manual, and we're talking about al_use_shader 💅 buckle up.

🌸 SYNOPSIS 🌸

#include <allegro5/allegro.h>

bool al_use_shader(ALLEGRO_SHADER *shader)

---

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — al_use_shader makes your shader the main character for all the drawing you do next on the current target bitmap. every subsequent drawing operation? yeah, that shader is running the show now. slay ✨

and if you wanna stop using any shader on the current target bitmap, you just pass NULL. that's it, no shader, back to normal vibes 🎀

it returns true on success 💖 otherwise it returns false — like, for example, when the shader is incompatible with the target bitmap. that's the vibe check failing, bestie, no cap 😭
