# Scene JSON Schema Definition

This document outlines the structure of the JSON files generated by the scene parser. The schema uses a highly compressed format with single or double-letter keys to reduce file size. This document serves as the legend to decode that structure.

---

## 1. Top-Level Object (`SceneData`)

The root object of the JSON file.

| Key | Property Name | Type | Description |
|:---:|:---|:---|:---|
| `p` | `PrefabsInScene` | `List<string>` | A list of all unique prefab GUIDs that are referenced by prefab instances within the scene. This property is omitted if no prefabs are used. |
| `h` | `Hierarchy` | `List<GameObjectData>` | A list of all root `GameObject`s in the scene. This property is omitted if the scene is empty. |

### Example
```json
{
  "p": [
    "f7d8f8f8f8f8f8f8f8f8f8f8f8f8f8f8",
    "a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6"
  ],
  "h": [
    { ...GameObjectData... },
    { ...GameObjectData... }
  ]
}
```

## 2. GameObject Object (`GameObjectData`)

Represents a single `GameObject` in the scene hierarchy.

| Key | Property Name | Type | Description |
|:---:|:---|:---|:---|
| `e` | `Enabled` | `boolean` | The active state of the GameObject. **Omitted if `true` (default).** |
| `n` | `Name` | `string` | The name of the GameObject. |
| `t` | `Tag` | `string` | The tag assigned to the GameObject. **Omitted if `"Untagged"` (default).** |
| `l` | `Layer` | `integer` | The layer number. **Omitted if `0` (default).** |
| `a` | `AnchorId` | `string` | The unique `fileID` of this GameObject within the scene file, used for referencing. |
| `pi`| `PrefabIndex` | `integer` | If this GameObject is a prefab instance, this is the 0-based index into the root `p` (PrefabsInScene) list. **Omitted if not a prefab.** |
| `c` | `Components` | `List<ComponentData>` | A list of all components on this GameObject. This is **only used for non-prefab objects**. For prefabs, overrides are stored in `ac` and `rc`. Omitted if empty. |
| `ac`| `AddedComponents` | `List<ComponentData>` | A list of components that were added to this specific prefab instance. Omitted if empty. |
| `rc`| `RemovedComponentAnchorIds` | `List<string>` | A list of `fileID`s for components that were removed from this specific prefab instance. Omitted if empty. |
| `ch`| `Children` | `List<GameObjectData>` | A list of child `GameObject`s. For prefabs, this only contains newly added children or original children that have overrides. Omitted if empty. |

## 3. Component Object (`ComponentData`)

Represents a single `Component` attached to a `GameObject`.

| Key | Property Name | Type | Description |
|:---:|:---|:---|:---|
| `t` | `Name` (Type) | `string` | The full C# type name of the component (e.g., `UnityEngine.Transform`, `MyGame.PlayerController`). |
| `a` | `AnchorId` | `string` | The unique `fileID` of this component within the scene file. |
| `f` | `Fields` | `object` | For `MonoBehaviour` scripts, this is a key-value map of all its serialized fields and their values. This property is omitted if the component is not a MonoBehaviour or has no serializable fields. |

### Example
```json
{
  "t": "UnityEngine.BoxCollider",
  "a": "1234567890"
}
```
```json
{
  "t": "MyGame.PlayerController",
  "a": "9876543210",
  "f": {
    "m_Speed": 5.5,
    "m_PlayerName": "Hero",
    "m_Target": {
      "type": "UnityEngine.Transform",
      "scene_object_id": 1122334455
    }
  }
}
```
