Here's the class in question: http://pastebin.com/hqGR6Cjm

The purpose of the MessageSyncClient class is to be sent from the server to the client, so it has to be registered on the server side. I'm not sure why it's referencing EntityPlayerSP too.

I think you call a client method in your "onMessage" method in the handler class.

Can you post the code of you "MessageSyncClientHandler" class?

http://pastebin.com/0FXgPP5C

 

I'm not sure how I would accomplish this without referencing the player. I was thinking about having a static class that would just hold the items in a field so that it won't have to reference any piece of Minecraft at all, but that seems hacky.

You need to call your actions on the main thread. From the Forge Documentation:

Quote

As of Minecraft 1.8 packets are by default handled on the network thread.

That means that your IMessageHandler can not interact with most game objects directly. The example above for example would not be correct. Minecraft provides a convenient way to make your code execute on the main thread instead using IThreadListener.addScheduledTask.

The way to obtain an IThreadListener is using either the Minecraft instance (client side) or a WorldServer instance (server side).

The Minecraft class doesn't exist on the server (it's @SideOnly(Side.Client)). To reference it, you need to make methods in your proxies which return the objects you need (i.e. the player) in the client proxy, and throw an exception in the server proxy (because they should never be called from there). I just had (and solved) this problem today - link!
