Questions about Proxies and main class

[kwill]

What are the proxies actually for? How do they compare to packet handlers? Tutorials constantly show to put graphic info, such as guis and such, but they never actually specify what it's doing. Also, what do you put in the pre-init, init , and post-init classes? I have been loading my blocks and items in the @init but someone recently said they belong in @preinit :C

Proxies allow you to register renderers, because the server doesn't HAVE a renderer, so trying to do so will throw class not found errors.

Just to clarify, would it be more apt to say that it allows client side function to not cause "class not found" on a server? I say this because I also run things like key binds through the proxy. I'm just trying to get a clear understanding for future reference.

The simplest way to look at the proxies are like this:

 

If on the server side, only the CommonProxy is called.

If on the Client side, the ClientProxy is called instead of the CommonProxy.

The ClientProxy may and usually do make calls to CommonProxy.

 

It's just a simple way to get a file where you safely can do all client only stuff without worrying about the server reading it. You can of course do this without using proxy files it's just more convenient to use them.
