Kryonet class not registered even though I register

Question

I'm making a 2d game and want to implement multiplayer , to be easier I'm using an API called Kryonet . Following this tutorial . The version of Kryonet I'm using is, like the tutorial, 1.04.

---

I saw all the 6 videos and my code looks a bit like him as you can see:

Client :

• Multiplayer class

• NetworkListener class

• Packets classes

Server :

• ServerMP class
• NetworkListener class
• Packets classes

---

It seems to be fine but then I run the server and the client and on client I get :

Server runs without an error.

Thanks in advance.

Answer 1

Just found the problem by looking at the Kryonet Examples , it was that on the register method at Multiplayer class it shouldn't be:

Kryo kryo = new Kryo();

But instead

Kryo kryo = client.getKryo();
