Hi @Project-Magenta, are you sure the server is running on port 3000?

@endel Ok thanks i' ll try it

Hi @karneaud, welcome! Sure, you can listen to "locked" and "unlocked" events from inside the room handler. Example: class MyRoom extends Room { onInit () { this.on("locked", () => console.log("room has been locked!")) this.on("unlocked", () => console.log("room has been unlocked!")) } } Cheers!

@merhawie said in Buffer not defined error: Buffer is not defined Hi @merhawie, that's right, I think you need to add "buffer" as a dependency on package.json. I've just added this to the RN caveats. import { Buffer } from "buffer"; import { AsyncStorage } from 'react-native'; window.localStorage = AsyncStorage; global.Buffer = Buffer;

Thanks @endel it is really helpfull

Hey @merhawie, Are you calling client.join() after the onOpen signal, as described here? https://github.com/gamestdio/colyseus.js#react-native-compatibility

games are stateful. It's very useful conception. Thank you again！

Thanks for replying~

Hi @diederik-van-remoortere, That's not supported currently, it's a nice proposal, though!

@endel So, I got this working by calling gameServer.matchMaker.create("game", {}); after registering (I only do this on the second process). It seems that the you are only subscribing to presence when the room is created. There is no knowledge that a registered handler is registered within presence. So, I have manually created the room on startup. This probably is not the best way, but it works for now while you can think about how we would want to solve for making the other game servers aware that a room is registered but not yet created.
