Hello @mrbug,

There’s a few examples of how to use `broadcastMessage` in our [project-template](https://github.com/heroiclabs/nakama-project-template/blob/master/match_handler.ts).

If you set the value to `null` then the message is broadcast to all the players connected to the match.

If you need to target specific subsets of players that will depend on your message handling server logic.

Best.

in template there is no targeted broadcast! and i don’t know how to get the targets list when using  
SendMatchStateAsync function in unity c# code.

In some places in the template it’s omitted, which effectively defaults to nil (broadcast to all).

In an authoritative multiplayer game you send some data to the server based on the protocol you’ve defined, and it’s up to the match loop implementation to target specific player or broadcast to all depending match state and received message.
