Hello,  
I am using Nakama Java SDK, however in java there is only:  
client.rpc(session…) but not client.rpc(httpsercetkey…).  
In unity, I often use client.RpcAsync(httpsercetkey…). Can Nakama Java SDK be updated further?  
Thank you.

Hello @dhforever, we’d encourage you to open a PR to add support for this method if you can, contributions are greatly appreciated.

Best.

I really want to do that. But my experience is poor.

You can still call the RPC’s via REST using a regular Java HTTP client, you should add the http key as a query param called `http_key`.

Hope this helps.

Thank you. I’m doing it.  
Sorry for bothering you, can I ask something else besides this topic?  
I don’t really understand the matchkick method yet, it is described below. How can a match owner kick another client out of that match?

```auto
let matchkick = function matchLoop(ctx, logger, nk, dispatcher, tick, state, messages) {
     logger.debug('Lobby match loop executed');

     dispatcher.matchKick(messages.map(function (message) {
         return message.sender;
     }));

     return {
         state: state
     };
}

```

As in your example above, just call `dispatcher.matchKick()` and pass the presence of the users to kick. Although in your example it seems like you’re kicking all clients that are sending a message to the match.

If you need a reference for how to implement match handlers, have a look at our [project template](https://github.com/heroiclabs/nakama-project-template/blob/master/match_handler.ts).

There are no examples of Matchkick specifically. I searched them all.  
Can you write an RPC function to kick 1 player with 1 userid from match?

There’s no example for kicking a player specifically, but you’d treat it like any of the other messages in the template.

First, define a message with an opcode to kick a player(s);  
Then, have a [case statement](https://github.com/heroiclabs/nakama-project-template/blob/master/match_handler.ts#L295) to handle the kick message. The client should send the list of players to kick in the payload of the message, you’d unmarshal it and call `dispatcher.matchKick()` with the list of said players.
