+# Match Replay JSON Format
+
+Guide for implementing the admin-panel replay viewer. Files are written by the Unity dedicated server (and practice host) to disk only.
+
+## Where files live
+
+```
+{ApplicationDirectory}/Logs/{matchId}_replay.json
+```
+
+| Match type | `matchId` in filename / JSON | Notes |
+|------------|------------------------------|--------|
+| Ranked / dedicated | Positive matchmaker id (e.g. `228`) | Same id as `Logs/228.txt` |
+| Practice / tutorial | Negative unix timestamp (e.g. `-1769539200`) | `isPractice: true`; unique per session |
+
+Example paths:
+
+- `Logs/228_replay.json`
+- `Logs/-1769539200_replay.json`
+
+## Top-level object
+
+```json
+{
+  "version": 1,
+  "matchId": 228,
+  "isPractice": false,
+  "fixedDeltaTime": 0.02,
+  "duration": 184.32,
+  "entities": [ /* ... */ ],
+  "frames": [ /* ... */ ],
+  "events": [ /* ... */ ]
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `version` | int | Schema version. Currently `1`. |
+| `matchId` | int | Match id (positive = ranked, negative = practice). |
+| `isPractice` | bool | `true` for localhost practice / tutorial host. |
+| `fixedDeltaTime` | float | Physics step used while recording (typically `0.02` → ~50 Hz). |
+| `duration` | float | Length of the recording in seconds (`t` of last sample / end). |
+| `entities` | array | Ball + pucks. Order defines pose array indices in every frame. |
+| `frames` | array | Time-ordered pose samples (~every FixedUpdate). |
+| `events` | array | Time-ordered discrete events (hits, goals, resets). |
+
+Time `t` everywhere is **seconds since recording start** (match start), not wall-clock UTC.
+
+---
+
+## Entities
+
+```json
+{ "id": 0, "type": "ball", "team": "" }
+{ "id": 1, "type": "puck", "team": "Red" }
+{ "id": 2, "type": "puck", "team": "Blue" }
+```
+
+| Field | Type | Values |
+|-------|------|--------|
+| `id` | int | Stable index `0 .. N-1`. Matches array index in each frame’s `x`/`y`/`vx`/`vy`. |
+| `type` | string | `"ball"` or `"puck"` |
+| `team` | string | `"Red"`, `"Blue"`, or `""` for ball |
+
+Entity list is fixed for the whole file. **Index `i` in a frame’s pose arrays always refers to `entities[i]`.**
+
+Typical order: ball first, then pucks sorted by team then spawn position.
+
+---
+
+## Frames (motion samples)
+
+```json
+{
+  "t": 12.40,
+  "x":  [0.0, 1.2, -0.5],
+  "y":  [0.1, -0.3, 2.0],
+  "vx": [0.0, 3.1, -1.0],
+  "vy": [0.2, 0.0, 0.5]
+}
+```
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `t` | float | Sample time in seconds (monotonic, increasing). |
+| `x`, `y` | float[] | World position per entity (Unity 2D world units). |
+| `vx`, `vy` | float[] | Linear velocity per entity at that sample (world units / second). |
+
+- Array length always equals `entities.length`.
+- Samples are dense (~`1 / fixedDeltaTime` Hz). Do **not** treat them as render frames.
+
+### Coordinate system
+
+Unity 2D world space:
+
+- Origin at field center
+- `+X` right, `+Y` up (as in Unity)
+- Scale matches the in-game pitch (see game `fieldSize` / art for admin canvas mapping)
+
+---
+
+## Events
+
+```json
+{ "t": 12.4, "type": "hit", "kind": "ball_wall", "vol": 0.6, "id": 0, "team": "", "redScore": 0, "blueScore": 0, "kickoff": false }
+{ "t": 30.1, "type": "goal", "kind": "", "vol": 0, "id": -1, "team": "Blue", "redScore": 1, "blueScore": 0, "kickoff": false }
+{ "t": 32.2, "type": "reset", "kind": "", "vol": 0, "id": -1, "team": "", "redScore": 0, "blueScore": 0, "kickoff": false }
+```
+
+All event objects share the same fields (Unity `JsonUtility` shape). Unused fields are empty / zero / `-1`.
+
+| Field | Used by | Description |
+|-------|---------|-------------|
+| `t` | all | Event time in seconds. |
+| `type` | all | `"hit"` \| `"goal"` \| `"reset"` |
+| `kind` | `hit` | `"puck_puck"` \| `"ball_puck"` \| `"ball_wall"` |
+| `vol` | `hit` | SFX volume `0..1` (from relative impact speed). |
+| `id` | `hit` | Entity id involved (spatial cue). `-1` if unknown. |
+| `team` | `goal` | **Conceding** side / goal owner (`"Red"` or `"Blue"`). The other team scored. |
+| `redScore` | `goal` | Score after this goal. |
+| `blueScore` | `goal` | Score after this goal. |
+| `kickoff` | `goal`, `reset` | Kickoff-goal / kickoff-style reset when `true`. |
+
+### Event semantics
+
+| `type` | Meaning for the viewer |
+|--------|-------------------------|
+| `hit` | Play collision SFX at `vol`. Optional: flash near entity `id`. |
+| `goal` | Goal scored against `team`. Update scoreboard to `redScore`/`blueScore`. Play goal SFX. **Discontinuity** — do not interpolate motion across this time. |
+| `reset` | Pieces are lerping / teleporting back. **Discontinuity** — snap poses; do not blend across. |
+
+First-to-3 wins; a completed match usually ends shortly after a goal that makes a score `3`.
+
+---
+
+## Playback contract (required for smooth motion)
+
+Recording is FixedUpdate (~50 Hz). Snapping happens if the viewer steps sample-by-sample without blending. Follow this:
+
+### 1. Drive time with wall clock
+
+```text
+playbackTime += (deltaMs / 1000) * playbackSpeed
+playbackTime = clamp(playbackTime, 0, duration)
+```
+
+Use `requestAnimationFrame` (or equivalent). Do **not** advance one JSON frame per rAF tick.
+
+### 2. Interpolate poses between samples
+
+Binary-search `frames` for neighbors where:
+
+```text
+frames[i].t <= playbackTime < frames[i+1].t
+```
+
+Then for each entity index `e`:
+
+**Minimum (good):** linear lerp of `x`/`y`:
+
+```text
+u = (playbackTime - t0) / (t1 - t0)
+x = lerp(x0[e], x1[e], u)
+y = lerp(y0[e], y1[e], u)
+```
+
+**Recommended (smooth under acceleration):** cubic Hermite using velocities:
+
+```text
+dt = t1 - t0
+u  = (playbackTime - t0) / dt
+u2 = u*u
+u3 = u2*u
+
+h00 =  2*u3 - 3*u2 + 1
+h10 =      u3 - 2*u2 + u
+h01 = -2*u3 + 3*u2
+h11 =      u3 -   u2
+
+x = h00*x0 + h10*dt*vx0 + h01*x1 + h11*dt*vx1
+y = h00*y0 + h10*dt*vy0 + h01*y1 + h11*dt*vy1
+```
+
+(Same for each entity index.)
+
+### 3. Snap across discontinuities
+
+Treat every `goal` and `reset` event as a cut:
+
+- When `playbackTime` crosses that event’s `t`, **do not** interpolate from the previous sample across the cut.
+- Seek to the frame at or immediately after `t` and snap positions.
+
+Practical approach: build a sorted list of discontinuity times from events where `type === "goal" || type === "reset"`. If `t0` and `t1` straddle a discontinuity, snap to the post-cut sample instead of lerping.
+
+### 4. Fire events once when crossed
+
+Keep `lastEventIndex` (or last fired `t`). When `playbackTime` advances past an event’s `t`, fire it once:
+
+- `hit` → SFX by `kind` / `vol`
+- `goal` → score UI + goal audio
+- `reset` → optional reset cue (usually silent)
+
+On seek / scrub: reset event cursor; either skip SFX or replay only from the new time forward.
+
+---
+
+## Suggested viewer pipeline
+
+```text
+Load JSON
+  → map entities to sprites (ball / red pucks / blue pucks)
+  → sort events by t (already ordered, but verify)
+  → each animation frame:
+       advance playbackTime
+       resolve poses (Hermite + discontinuity snaps)
+       draw entities
+       dispatch newly crossed events
+```
+
+### Seeking / scrubbing
+
+1. Set `playbackTime` to the scrub value.
+2. Find the nearest frame (or interpolate as above).
+3. Recompute score from the last `goal` event with `t <= playbackTime` (else `0–0`).
+4. Reset the event-fire cursor to that time so SFX don’t spam.
+
+### Scoreboard without scrubbing
+
+Start at `0–0`. On each `goal` event, set scores from that event’s `redScore` / `blueScore`.
+
+---
+
+## Minimal TypeScript types
+
+```ts
+export interface ReplayFile {
+  version: number;
+  matchId: number;
+  isPractice: boolean;
+  fixedDeltaTime: number;
+  duration: number;
+  entities: ReplayEntity[];
+  frames: ReplayFrame[];
+  events: ReplayEvent[];
+}
+
+export interface ReplayEntity {
+  id: number;
+  type: "ball" | "puck" | string;
+  team: "Red" | "Blue" | "" | string;
+}
+
+export interface ReplayFrame {
+  t: number;
+  x: number[];
+  y: number[];
+  vx: number[];
+  vy: number[];
+}
+
+export interface ReplayEvent {
+  t: number;
+  type: "hit" | "goal" | "reset" | string;
+  kind: "puck_puck" | "ball_puck" | "ball_wall" | "" | string;
+  vol: number;
+  id: number; // entity id, or -1
+  team: "Red" | "Blue" | "" | string; // conceding team on goal
+  redScore: number;
+  blueScore: number;
+  kickoff: boolean;
+}
+```
+
+---
+
+## Checklist for a correct viewer
+
+- [ ] Time driven by real elapsed time × speed, not frame index
+- [ ] Poses interpolated between samples (Hermite preferred)
+- [ ] No interpolation across `goal` / `reset`
+- [ ] Entity index `i` always matches `entities[i]`
+- [ ] Hit SFX use `kind` + `vol`
+- [ ] Goal `team` means **conceding** side
+- [ ] Practice files filtered via `isPractice` or negative `matchId`
+
+## Out of scope (not in the JSON)
+
+- Player names / user ids (use matchmaker / match API by `matchId` for ranked games)
+- Camera / UI layout
+- Launch aim lines / turn timer
+- Network latency or client prediction
