When I play SSP all is fine. I make a dimension and I can then teleport to it. However, when I do this on a server I get a crash at clientside:

The code to create the dimension is (on the server side):

 

        DimensionManager.registerProviderType(id, GenericWorldProvider.class, false);
        DimensionManager.registerDimension(id, id);

 

And to teleport to the dimension I do (on the server side):

 

            WorldServer worldServerForDimension = MinecraftServer.getServer().worldServerForDimension(message.dim);
            MinecraftServer.getServer().getConfigurationManager().transferPlayerToDimension((EntityPlayerMP) player, message.dim,
                    new RfToolsTeleporter(worldServerForDimension, message.x, message.y+1, message.z));

 

Apparently this is not sufficient for the client. What do I have to do so that the client also gets to know the new dimension? Do I have to manually send a packet to the client and register the dimension there or is there some automatic way to do that?

 

Edit: and related to this. I'm also using this code to register the dimensions when the server is started:

 

    @EventHandler
    public void serverStarted(FMLServerStartedEvent event) {
        ModDimensions.initDimensions();
    }

 

Where can I do the equivalent for client-side?

 

Thanks,

I'm making a mod similar to mystcraft (but then in a more technological fashion). This means the dimensions are dynamically created and associated with your world. So I don't know what dimensions there are at preInit time. The dimension information is stored in the mapStorage. (edited, I mean mapStorage of course)

 

 

I just tried to do it with a PlayerEvent.PlayerLoggedInEvent. As soon as the player logs in it sends over a packet to the client with all the dimensions to register. However it comes too late. The client has already gone on and tried to load the player in my dimension which obviously not exists yet. So I think this is something that I have to do on the client somehow. Anyone? I know it is possible as Mystcraft achieves it. Just need to find out how.

Ok, thanks to the people at #minecraftforge I managed to get a solution by catching FMLNetworkEvent.ServerConnectionFromClientEvent on the server and then from there sending a message to the client to register all dimensions. Problem solved!
