ALLEGRO_VERTEX(3)

💅 ALLEGRO_VERTEX(3) — from the Library Functions Manual, Allegro 5 API ✨

okay bestie, welcome to the ALLEGRO_VERTEX(3) page 🦋 this one is part of the Allegro 5 API, and it’s literally all about the generic vertex type. No cap.

💖 NAME 🎀

ALLEGRO_VERTEX — Allegro 5 API ✨

🌸 SYNOPSIS 🌸

#include <allegro5/allegro_primitives.h>

typedef struct ALLEGRO_VERTEX ALLEGRO_VERTEX;

🦋 DESCRIPTION 🦋

okay so this struct is the generic vertex type, and it’s giving 3D position, color, and texture coordinates for a single texture, all in one little package 💅.

🚨 Important tea, bestie: at this time, the software driver for this addon cannot render 3D primitives. Like, it’s just not happening with that driver right now.

If you want a 2D only primitive, set z to 0 🎀.

⚠️ And listen: you must initialize all members of this struct when you’re using it. That’s the rule.

One exception to this rule are the u and v variables, which can be left uninitialized when you are not using textures ✨.

🍓 Fields 🍓

• x, y, z — Position of the vertex (float) 📍
• u, v — Texture coordinates measured in pixels (float) 🧵
• color — ALLEGRO_COLOR(3) structure, storing the color of the vertex 🎨

👑 SEE ALSO 👑

• ALLEGRO_PRIM_ATTR(3) 💜
