Editor-only package. Registers **Access Control** (`.ac`) and **Game Overrides** (`.ugo`) file types with the Deployment Window (`com.unity.services.deployment`).
- **Package:** `com.unity.services.tooling`
- **Namespace:** `Unity.Services.Tooling.Editor.AccessControl.Authoring.Core.Model` / `Unity.Services.Tooling.Editor.GameOverrides.Authoring.Core.Model`
---
## Overview
Tooling provides two cloud resource file types deployed through the Deployment Window:
| File Type | Extension | Purpose |
|---|---|---|
| Access Control | `.ac` | Permit or deny player/service-account access to UGS services on a URN basis |
| Game Overrides | `.ugo` | A/B testing and audience targeting by overriding Remote Config values for player segments |
Both file types are created via right-click in the Project window → **Create > Unity Gaming Services** and deployed via **Services > Deployment**.
---
## Access Control
Access Control policies permit or deny access to UGS services on a **URN basis**. Each statement targets a resource URN pattern and applies a `Read`, `Write`, or `*` action for a principal (`Player` or `ServiceAccount`). **Deny takes precedence over Allow.**
| Concept | Description |
|---|---|
| **Effect** | `"Allow"` or `"Deny"` — Deny takes precedence over Allow |
| **Action** | `"Read"`, `"Write"`, or `"*"` (both) |
| **Principal** | `"Player"` (end user) or `"ServiceAccount"` (server/admin) |
| **Resource** | URN pattern — `urn:ugs:<service>:/<path>` with `*` and `**` wildcards |
Common use cases:
- Deny direct player writes to Cloud Save (force writes through Cloud Code)
- Deny player currency/inventory writes in Economy (only allow purchases)
- Restrict Cloud Code module/script invocation to specific endpoints
- Deny player account deletion or identity unlinking
### `.ac` File Format
**Create via:** Right-click in Project window → **Create > Unity Gaming Services > Access Control**
```json
{
"$schema": "https://ugs-config-schemas.unity3d.com/v1/project-access-policy.schema.json",
"statements": [
{
"Sid": "DenyPlayerCloudSaveWrites",
"Effect": "Deny",
"Action": ["Write"],
"Principal": "Player",
"Resource": "urn:ugs:cloud-save:/**"
}
]
}
```
| Field | Type | Description |
|---|---|---|
| `Sid` | `string` | Unique statement ID within the file |
| `Effect` | `string` | `"Allow"` or `"Deny"` — Deny wins over Allow |
| `Action` | `string` or `string[]` | `"Read"`, `"Write"`, or `"*"` (both) |
| `Principal` | `string` or `string[]` | `"Player"` (end user) or `"ServiceAccount"` (server/admin) |
| `Resource` | `string` or `string[]` | URN pattern — `urn:ugs:<service>:/<path>` |
### URN Pattern Format
```
urn:ugs:<service>:/<path>
```
- `*` matches a single path segment
- `**` matches zero or more path segments (including nested)
- `/**/` is commonly used to skip environment/version segments in the URL

### Recommended Pattern: Deny-All-Then-Allow
Start with a blanket deny, then explicitly allow only what the player needs. This ensures new services are locked down by default.

```
This policy:
- **Denies** all UGS access by default
- **Allows** authentication (anonymous, external, session token sign-in; link external ID; read player info)
- **Denies** identity unlinking and player deletion (inherited from blanket deny)
- **Allows** economy reads (config, currencies, inventory) and purchases (virtual, Google Play, Apple App Store)
- **Denies** direct currency/inventory writes (inherited from blanket deny — use Cloud Code for server grants)
- **Allows** leaderboard reads
- **Allows** Cloud Save player data reads/writes for own data (Default items), public data reads, game-wide data reads
- **Denies** Cloud Save blanket writes (Protected data only writable via Cloud Code)
- **Allows** Cloud Code module, script, and subscription token access

## Game Overrides
Game Overrides are the A/B testing and audience targeting mechanism for UGS. They override **Remote Config** values for specific player segments (audiences). Remote Config itself does not provide A/B testing — Game Overrides layer on top of it.
Use cases:
- A/B test different XP multipliers for player segments
- Roll out features gradually to targeted audiences
- Run time-limited promotions with different reward values
### `.ugo` File Format
**Create via:** Right-click in Project window → **Create > Unity Gaming Services > Game Override**
```json
{
"GameOverrides": [
{
"id": "double-xp-weekend",
"name": "Double XP Weekend",
"enabled": true,
"audiences": ["high_engagement_players"],
"overrides": [
{
"key": "xp_multiplier",
"value": 2.0
}
]
}
]
}
```
| Field | Type | Description |
|---|---|---|
| `id` | `string` | Unique override ID |
| `name` | `string` | Human-readable name |
| `enabled` | `bool` | Whether this override is active |
| `audiences` | `string[]` | Segment IDs from Unity Segmentation |
| `overrides[].key` | `string` | Remote Config key to override |
| `overrides[].value` | `any` | Replacement value |

## Editor API Models
### Access Control
```csharp
namespace Unity.Services.Tooling.Editor.AccessControl.Authoring.Core.Model
{
interface IProjectAccessFile
{
string Path { get; }
string Name { get; }
List<IAccessControlStatement> Statements { get; }
}
interface IAccessControlStatement
{
string Sid { get; } // Statement ID — unique within the file
string Effect { get; } // "Allow" or "Deny" — Deny takes precedence
List<string> Action { get; } // "Read", "Write", or "*" (both)
List<string> Principal { get; } // "Player" or "ServiceAccount"
List<string> Resource { get; } // URN pattern(s) the rule applies to
}
}
```
### Game Overrides
```csharp
namespace Unity.Services.Tooling.Editor.GameOverrides.Authoring.Core.Model
{
interface IGameOverride
{
string Id { get; }
string Name { get; }
bool Enabled { get; }
List<string> Audiences { get; }
List<OverrideConfig> Overrides { get; }
}
class GameOverridesConfigFile
{
public List<IGameOverride> GameOverrides { get; }
}
}
```
Both file types are discovered automatically by the Deployment Window when `com.unity.services.deployment` is installed.
