💖 ALLEGRO_SAMPLE_INSTANCE 💖

okay bestie, buckle up, we're reading a page out of the Allegro reference manual (that's the 3alleg5 edition, for the record) and it's all about one very specific little guy. say hi to ALLEGRO_SAMPLE_INSTANCE 🎀

✨ NAME ✨

ALLEGRO_SAMPLE_INSTANCE — the Allegro 5 API, but make it a sound effect you can actually press play on 🔥

🌸 SYNOPSIS 🌸

#include <allegro5/allegro_audio.h>

typedef struct ALLEGRO_SAMPLE_INSTANCE ALLEGRO_SAMPLE_INSTANCE;

like, that's it. that's the whole declaration. she's an opaque struct and she knows it 💅

🦋 DESCRIPTION 🦋

so an ALLEGRO_SAMPLE_INSTANCE object? it represents a playable instance of a predefined sound effect. think of it as one single "go" button for a sound you already have loaded. 👑

it holds all the info about how that effect should actually be played. these playback parameters are, and I'm quoting the vibe here, literally:

  • the looping mode
  • the loop start/end points
  • the playing position
  • the speed
  • the gain
  • the pan
  • the playmode

and on top of all that, whether the sample instance is currently playing or paused is also one of its properties. so yeah, she keeps receipts on her own state. 📝

an instance uses the data from an ALLEGRO_SAMPLE(3alleg5) object. and here's the cute part — multiple instances can be created from the same ALLEGRO_SAMPLE. so one sample, many instances, no jealousy, we love a polyamorous data structure moment. 🌈

⚠️ but listen. an ALLEGRO_SAMPLE must not be destroyed while there are instances which reference it. do NOT do it. that's the kind of thing that ruins the whole group chat. 💀

and now the part where the sound actually, y'know, comes out: to actually produce audio output, an ALLEGRO_SAMPLE_INSTANCE must be attached to an ALLEGRO_MIXER(3alleg5) which eventually reaches an ALLEGRO_VOICE(3alleg5) object. it's giving chain of command. instance → mixer → voice → your ears. the pipeline is real and she is iconic 🧚
