# slopsmith-plugin-minigames
|
|
|
|
The minigame framework for [Slopsmith](https://github.com/got-feedback/feedback).
|
|
|
|
This plugin provides:
|
|
|
|
- A **Minigames hub** screen that discovers every installed minigame plugin and lists them as tiles with leaderboards.
|
|
- A **shared profile** (XP, level, unlocks, totals) that aggregates runs across every minigame.
|
|
- A JS **SDK** exposed at `window.slopsmithMinigames` that minigame plugins use to access scoring, HUD primitives, run persistence, and a scheduler — so individual minigames do not need their own DSP or backend.
|
|
|
|
## Writing a minigame
|
|
|
|
A minigame is a standard Slopsmith plugin that:
|
|
|
|
1. Adds a `minigame` block to its `plugin.json`:
|
|
|
|
```json
|
|
{
|
|
"id": "my_game",
|
|
"name": "My Game",
|
|
"version": "0.1.0",
|
|
"script": "game.js",
|
|
"minigame": {
|
|
"title": "My Game",
|
|
"tagline": "Short pitch",
|
|
"type": "chart-free",
|
|
"scoring": "pitch-continuous",
|
|
"thumbnail": "thumb.png"
|
|
}
|
|
}
|
|
```
|
|
|
|
2. On script load, registers itself with the SDK using the safe late-binding
|
|
pattern (minigame plugins may load before the SDK; the pending queue
|
|
handles both orderings — the SDK drains it on init, and the
|
|
`slopsmith-minigames-ready` event is an alternative for plugins that prefer
|
|
event-driven registration):
|
|
|
|
> **Important:** `spec.id` must exactly match the `id` field in `plugin.json`.
|
|
> The backend registry uses `plugin_id` (sourced from `plugin.json`) and the
|
|
> hub UI merges manifest metadata (title, tagline, thumbnail, modifiers) by
|
|
> that key. If `spec.id` and `plugin.json` `id` diverge, runs and leaderboard
|
|
> data will be attributed to an unrecognised game and display metadata (title,
|
|
> thumbnail) will fall back to JS-spec values rather than the richer manifest
|
|
> values.
|
|
|
|
```js
|
|
const spec = {
|
|
id: 'my_game',
|
|
start: ({ container, modifiers, sdk }) => { /* mount game into container */ },
|
|
stop: () => { /* tear down */ },
|
|
};
|
|
|
|
if (window.slopsmithMinigames) {
|
|
window.slopsmithMinigames.register(spec);
|
|
} else {
|
|
(window.__slopsmithMinigamesPending = window.__slopsmithMinigamesPending || []).push(spec);
|
|
}
|
|
```
|
|
|
|
3. Calls `window.slopsmithMinigames.end({ score, durationMs, modifiers, meta })` when the run ends.
|
|
|
|
See [`slopsmith-plugin-flappy-bend`](https://github.com/got-feedback/feedback-plugin-flappy-bend) for a working example.
|
|
|
|
## SDK reference
|
|
|
|
`window.slopsmithMinigames` exposes:
|
|
|
|
- `register(spec)` — declare a minigame
|
|
- `start(gameId, opts)` / `end(result)` — lifecycle
|
|
- `scoring.createContinuous(opts)` — emits per-frame pitch (YIN, ~60 Hz)
|
|
- `scoring.createDiscrete(opts)` — wraps `createNoteDetector`, emits hit/miss
|
|
- `scoring.createChord(opts)` — full chord scorer (delegates to note_detect)
|
|
- `ui.mountHUD(html)` / `ui.runSummary(result)` / `ui.modifierPicker(defs)`
|
|
- `submitRun(...)` / `getLeaderboard(...)` / `getProfile()`
|
|
- `scheduler.every(ms, cb)` / `in(ms, cb)` / `cancel(id)`
|
|
|
|
## Dependencies
|
|
|
|
- `slopsmith-plugin-notedetect` >= 1.10.0 — required for discrete/chord scoring modes (continuous mode is self-contained).
