Any ideas as to why this isn't working?

[Draco18s]

Annotations are little more than comments that induce extra error checking.  They don't actually get compiled.

(There may be some exceptions, such as @Mod and @NetworkMod)

 

My guess is that you never registered onServerStarted as an event handler.

[charsmud]

Yea, that would be it... How would I register it as an event handler?  I've never actually done much with event handlers, so I'm sort of a beginner at that. 

[opssemnik]

question: u know these only work on dedicated server right?

[Draco18s]

Yea, that would be it... How would I register it as an event handler?  I've never actually done much with event handlers, so I'm sort of a beginner at that.

 

Hooray a wiki!  It even has a link to a nice tutorial.

[charsmud]

Hm.... I've managed to get it to print inside of the method, meaning I was able to register the new packet.  However, the stuff does not expand anymore!    Here's my changed code:
