:D that helps..

 

I have one more problem.

 

This is my message class:

public class ClientMessage implements IMessage {
    private boolean a;

    public ClientMessage() {
    }

    public ClientMessage(boolean a) {
        this.a = a;
    }

    @Override
    public void fromBytes(ByteBuf buf) {
        try {
            a = buf.readBoolean();
        } catch (IndexOutOfBoundsException e1) {
			..
        }
    }

    @Override
    public void toBytes(ByteBuf buf) {
        buf.writeBoolean(a);
    }

    public static class Handler implements IMessageHandler<ClientMessage, IMessage> {
        @Override
        public IMessage onMessage(ClientMessage message, MessageContext ctx) {

			THIS		
      
            return null;
        }
    }
}

 

with this in my core class

    public void init(FMLInitializationEvent event) {
        network.registerMessage(ClientMessage.Handler.class, ClientMessage.class, 0, Side.SERVER);
    }

 Now if I call it with this:

    @SubscribeEvent
    public void onClientConnect(FMLNetworkEvent.ClientConnectedToServerEvent event) {
        core.network.sendToServer(new ClientMessage(a));
    }

 

Command THIS in onMessage method, never executes.

You shouldn't be catching IndexOutOfBoundsException, it should be allowed to propagate up to FML's exception handling and/or crash the game. It's only thrown when you've done something wrong that should be fixed.

 

Is the IMessageHandler scheduling a task on the main thread to perform its action? Is it being called at all?

Please don't PM me to ask for help. Asking your question in a public thread preserves it for people who are having the same problem in the future.

EntityJoinedWorldEvent is probably the best

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.
