Can't get Message sending with Channel to work

[mardzie]

Hi,

for the last few days I tried to get a simple lightyear client and server to work so the client sends messages over a channel to the server and the server prints them.

I created two minimal examples. One custom that I made and one I copied from the examples and added my message sending.
None of them work.

I always get a ChannelNotFound error like the one below:
ERROR lightyear_transport::plugin: error sending message: ChannelNotFound(ChannelKind(TypeId(0xfdb81f78398778465ec5cdc2d5fd6e9e)))

There is more info in the repository.

Thank you

Sorry it's not very clear, but entities can only send / receive message if:

• they have the MessageSender or MessageReceiver component
• the Transport component has the relevant channel registered (transport.add_sender_from_registry or transport.add_receiver_from_registry)

As a helper, I provide for convenience the add_direction method that will register the channels/messages on Client or Server entities.

In your case, you just need to add .add_direction(NetworkDirection::Bidirectional) to the channel registration

        app.add_channel::<UnorderedReliableChannel>(ChannelSettings {
            mode: ChannelMode::OrderedReliable(ReliableSettings::default()),
            ..Default::default()
        }).add_network_direction(NetworkDirection::Bidirectional);

The ergonomics/docs can certainly be improved
