al_draw_line(3)

💅 al_draw_line — Allegro 5 API, bestie edition ✨

Okay so this is straight out of the Allegro reference manual, and it's genuinely one of the cutest little primitives you'll ever meet. We're talking al_draw_line — the icon, the main character, the "I just need one line fr fr" of the Allegro 5 API. 🎀

---

✨ SYNOPSIS ✨

Like, here's the whole vibe, verbatim, no cap:

#include <allegro5/allegro_primitives.h>

void al_draw_line(float x1, float y1, float x2, float y2,
   ALLEGRO_COLOR color, float thickness)

Yes bestie, that's allegro_primitives.h — you gotta include it or nothing works and you'll be sad. 🫶

🌸 DESCRIPTION 🌸

It draws a line segment between two points. That's it. That's the whole thing. Two points, one line, slay. ✨

🦋 Parameters (aka the cast of characters)

• x1, y1, x2, y2 — the start and end points of the line. So like, where it begins and where it ends. Iconic coordinates behavior. 📍
• color — the color of the line. Pick your vibe. 💜
• thickness — the thickness of the line. And listen, this part matters: pass <= 0 to draw hairline lines. That's the move when you want it whisper-thin. 🧚

Lowkey important: <= 0 doesn't mean "no line", it means hairline line. Don't panic. 💀

• al_draw_soft_line(3) — the other line function, go say hi 👑

And that's the whole page, bestie — go draw some lines, you're gonna ate 💅✨
