So i figured out u can use simple networking not only to send messages but also check if the message was received and respond to it. But i dont quite know how to do this...here is a example on what I coded.  https://gyazo.com/67947cfd9d61b9604f7118879a4ca58c

For the future, please post your code as text, not images.

As for the responses, due to the fact that IMessage is now handled asynchronously on the netty thread the response mechanic is pretty much not usable.

Ok, thx for the help !
