Vivox provides a text chat service:
-
Text chat - channel-based and directed text chat.
- Chat messages can contain any language or content up to service-defined size and rate limits.
- Chat messages are transported over TLS. No chat messages are saved or archived.
The following additional features can be enabled:
- Adaptive Chat filter
- Chat history - Core SDK and Unity SDK v16 only.
- Text evidence management
- Edit and delete messages - Core SDK and Unity SDK v16 only.
- Offline direct messages - Core SDK and Unity SDK v16 only.
- Anti-flooding
- Large text channel support
- Retrieve conversations list - Core SDK and Unity SDK v16 only.
- Set Chat Markers - Core SDK and Unity SDK v16 only.
- Channel-specific options - Core SDK only.
The server can customize a maximum byte count for text messages in its pre-login configuration. By default, the maximum is 320 bytes with UTF-8 encoding. A text message that exceeds the maximum length in bytes is rejected with a VxErrorMessageTextTooLong error.
Text chat requires a Unicode-supported system to work properly. The Unity Editor has full Unicode support in versions 2017.1 and later.
The following table details text chat policy:
| Service | Policy option | Default | Description |
Standard text chat | rate_limit | 1000 bytes per second | The maximum rate at which a player can send data over text chat.
This is configured server-side by Vivox. |
