al_set_shader_int(3alleg5)

💖 al_set_shader_int — Allegro 5 API 💖

okay bestie, pull up a chair, we're in the Allegro 5 manual and this one is a lil cutie 🎀

---

✨ SYNOPSIS ✨

#include <allegro5/allegro.h>

bool al_set_shader_int(const char *name, int i)

like, that's the whole vibe. one function, two args, one bool coming back at ya 🦋

---

🌸 DESCRIPTION 🌸

So. You know how your current target bitmap can have a shader on it? (main character energy, honestly). Well al_set_shader_int sets an integer uniform on that shader — the one belonging to whatever bitmap you're currently targeting. Not some other shader. That one. iykyk 💅

You hand it a name (the uniform's name, a const char *) and an i (the integer value you wanna shove in there), and it does the thing.

It returns true on success. 🎉

Otherwise it returns false — for example, if the uniform by that name literally does not exist in the shader. yeah. that happens. the shader is like "never heard of her" and you get a false. not a crash, just a lil rejection. 💀

• al_use_shader(3alleg5)

like yeah, go look at how you actually attach a shader, because setting a uniform on a shader nobody's using is giving... nothing. 🙈
