Text chat developer guide
The Vivox Unity SDK provides the following messaging features:
Note that:
- 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.
You can enable any of the following additional features :
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. |
