Vivox text messages can send additional, non-messaging data through two string variables:
- Application stanza namespace
- Application stanza body
注
This information is hidden from the player and is only accessible through the code.
注
Messages must contain data. You cannot send an empty message.
Unreal application stanza body
The following examples detail how to send hidden data through text messages and access hidden data from messages in the Vivox Unreal SDK.Send hidden data in group messages
FString Message = playerInput; //Hello World!FString ApplicationStanzaNamespace = TEXT("team:color");FString ApplicationStanzaBody = TEXT("red");IChannelSession::FOnBeginSendTextCompletedDelegate SendChannelMessageCallback;SendChannelMessageCallback.BindLambda([this, channelId, Message](VivoxCoreError Error) { if (VxErrorSuccess == Error) { UE_LOG(LogVivoxGameInstance, Log, TEXT("Message sent to %s: %s \n"),*channelId.Name(), *Message); } return;});currentChannelSession.BeginSendText("", *Message, ApplicationStanzaNamespace, ApplicationStanzaBody, SendChannelMessageCallback);
Send hidden data in directed messages
FString Message = playerInput; //Hello World!FString ApplicationStanzaNamespace = TEXT("team:color");FString ApplicationStanzaBody = TEXT("red");ILoginSession::FOnBeginSendDirectedMessageCompletedDelegate SendDirectedMessageCallback;SendDirectedMessageCallback.BindLambda([this, accountName, message](VivoxCoreError error, const FString &request_id){ if (VxErrorSuccess != error) { UE_LOG(LogVivoxGameInstance, Error, TEXT("BeginSendDirectedMessage() returned %d:%s"), error, ANSI_TO_TCHAR(FVivoxCoreModule::ErrorToString(error))); } return;});currentLoginSession.BeginSendDirectedMessage(AccountId(VIVOX_VOICE_ISSUER, accountName, VIVOX_VOICE_DOMAIN), "", Message, ApplicationStanzaNamespace, ApplicationStanzaBody, SendDirectedMessageCallback);
Access hidden data from messages
if(textMessage.ApplicationStanzaNamespace == “team:color”){ if(textMessage.ApplicationStanzaBody == “red”) { //font becomes red } else if(textMessage.ApplicationStanzaBody == “blue”) { //font becomes blue } else { //font becomes grey }}
