Proximity voice chat on multiplayer game servers

You can use the Redpoint Voice Chat component to automatically manage voice chat on multiplayer servers. It simplifies your voice chat implementation by managing voice chat channels for connected players, and can route each player's voice chat audio to the pawns they currently possess.

Understanding voice chat groups​

The voice chat component simplifies the implementation by allowing you to set the "voice chat group" on each player. Players with the same voice chat group will be able to hear each other. You don't need to know or manage voice chat channel names when using the voice chat component.

Some common implementations are:

  • If you are building a cooperative game and you want all players on the server to hear each other, leave all players in voice chat group 0.
  • If you are building a competitive game and you want team members to hear each other, set the voice chat group to the team ID.

You can change the voice chat group at any time on the game server, and players will connect to the correct voice chat channel automatically.

Add the Redpoint Voice Chat component to your player controller​

To use the component, you first need to add the component to your player controller blueprint:

Search for the Redpoint Voice Chat component from the dropdown when adding a component to your player controller

Configure the Redpoint Voice Chat component​

After adding the component, there are only a few settings to configure:

A screenshot of the voice chat component details

  • Voice Chat Group: Players with the same voice chat group set will be in the same voice chat channel.
  • Proximity Type:
    • If set to 'None', no proximity or spatialisation will be applied to this player's voice chat audio when they are heard by other players.
    • If set to 'Possessed Pawn', the player's voice chat audio will appear to be coming from their possessed pawn or character on other game clients.
    • If set to 'Custom', the player's voice chat audio will appear to be coming from the actor you have set on the server via the "Set Custom Audio Anchor Point".
  • Attenuation Settings: If proximity type is not set to None, you must set the attenuation settings which specifies how sound propagates in the game world, including the maximum distance at which the voice chat audio will be heard.
