✨ SYNOPSIS ✨

#include <allegro5/allegro_primitives.h>

void al_draw_filled_polygon(const float *vertices, int vertex_count,
   ALLEGRO_COLOR color)

---

🌸 DESCRIPTION 🌸

so. you wanna draw a filled, simple polygon. and "simple" here is not a compliment about its personality — it means the shape does not have to be convex (so it can be all curvy and chaotic, that's fine), but it must not be self-overlapping. no crossing your own edges, babe. that's the rule.

the parameters, one by one, because we don't gatekeep:

• vertices — interleaved array of (x, y) vertex coordinates. yes, x then y then x then y, living their best interleaved life. 🦋
• vertex_count — number of vertices in the array. how many little points you're feeding it.
• color — color of the filled polygon. the fit. the lewk. 💅

ok now the important one, no cap: when the y-axis is facing downwards (which is the usual case, the standard vibe), the coordinates must be ordered anti-clockwise. don't do it clockwise, bestie, that's not the move.
