💖 NAME 💖

• al_build_shader — Allegro 5 API

✨ SYNOPSIS ✨

#include <allegro5/allegro.h>

bool al_build_shader(ALLEGRO_SHADER *shader)

---

🛠️ DESCRIPTION 🛠️

bestie, this function is the required glow-up step before your shader can be used with al_use_shader(3) 💅 It should be called after you’ve successfully attached the pixel and/or vertex shaders with al_attach_shader_source(3) or al_attach_shader_source_file(3). No skipping the line, okay?

It returns true on success and false on error — and when it errors, the error log is updated 😭 You can retrieve that error log with al_get_shader_log(3).

Note: If you are using the ALLEGRO_PROGRAMMABLE_PIPELINE flag, then you must specify both a pixel and a vertex shader sources for anything to be rendered. That’s not a suggestion, bestie — both sources or nothing renders 💀
