[RESOLVED] Server-Side only mod

[vista200]

Hi there!

 

This is my first post, so please bare with my (or my skills... or understanding of "everything").

 

I searched for a good while on this forums before registering, but I was not able to find the information I need. As you can conclude from the title, I want a server-side only mod. From other threads in this forums I recap, that I need to have Forge installed on the clients. But what is actually not clear to me is, that I definitively need my mod on the client's side, even if it does not add any blocks or something.

 

First of all, what am I planning to do?

I want to write a mod, that hooks events like logging in and out, getting an achievement, player dies, kills a mob etc and sends a web request to a certain website. Actually, I want to create a battle log.

 

Which problem arises?

I developed my plugin within Eclipse so far, hitting the green play button several times. It worked flawlessly, except the logout event. I found out, that this is only caught server-side, so I opted for a server-side plugin.

I compiled a .jar file and threw it into my server's mods folder. It got loaded (referring to the log), but when I tried to connect to the server with my 1.7.10-Forge client, the login got rejected with the message "mods rejected: [FMLMod:webhookmod{1.0}]".

 

What is the correct approach to solve this error? The @NetworkMod annotation is gone, so is the @SideOnly. Do I have to have stubbed functions for the client? Is it enough to have the Listener registered without having any listening methods in it? How do I get the executing environment (Client/Server)?

In short: What is the correct approach?

Find my code attached at the bottom.

 

The actual API calls should only be fired server-side, because players could argue, that sending an additional HTTP request may have produced some lag on their side (while sending it from the server, all players would be affected equally).

 

Small update

I stumbled upon Proxies. I guess this is what I need to implement. By having my Client overwriting the Server class, it seems that this solves my problem. Thanks for the views

If you want to allow clients to connect without the mod installed, add

acceptableRemoteVersions = "*"

to your @Mod.
