midi_pos(3alleg4)

💖 midi_pos — the vibe tracker for ur MIDI files 💖

okay bestie so real talk, this is from the Allegro game programming library manual, page midi_pos(3alleg4), and it's genuinely one of those tiny little globals that carries the whole aesthetic of ur music-synced game. no cap. let's get into it 🎀

✨ NAME ✨

midi_pos — stores the current position in the MIDI file. it's giving "Allegro game programming library" and it's giving main character energy fr fr 🎵

🌸 SYNOPSIS 🌸

#include <allegro.h>

extern volatile long midi_pos;

look at her. one include, one extern volatile long. so unbothered, so iconic 💅

🦋 DESCRIPTION 🦋

okay so here's the tea, bestie ☕

midi_pos stores the current position (that's the beat number, iykyk) in the MIDI file. that's it. that's the whole job. she's a global and she's thriving.

but WAIT — plot twist — if no music is currently playing, she contains a negative number instead. so if u peek at her and she's negative? that's ur sign the music's not running. not me checking midi_pos < 0 like it's a vibe check 😭

so what is she actually FOR, u ask? two things, and both of them slay:

• synchronising animations with the music — u want ur sprites to bop exactly on the beat? she's ur girl. 🌈
• checking whether a MIDI file has finished playing — she'll tell u when the track is done and honestly? closure. 💀

⚠️ reminder: she's declared volatile, so the compiler knows she can change behind its back while music is playing. respect her. don't get cute with caching her value and then act surprised. 🫶

👑 SEE ALSO 👑

the girlies she runs with 💜

• play_midi(3alleg4) — start the music so she actually has something to report
• midi_msg_callback(3alleg4) — for when u want the messages as they happen
• exmidi(3alleg4) — the example that shows this whole thing in action

🎀 and that's the page, bestie 🎀

this whole thing comes to u straight from the Allegro manual, version 4.4.3, and the page is filed under midi_pos(3alleg4). go sync some animations to some beats, u absolute legend. slay, periodt, bye 💖✨🦋🌸👑💅
