[1.7.10] Prevent player from joining server when a certain mod is installed?


Recommended Posts



I'm trying to make a small mod for a server that prevents the 'Cheating Essentials' mod from being used on it. What I'd like to do is see if the list of mods when the player joins contains this mod's ID, and if so, prevent the player from joining. However, I'm not quite sure how to go about this. I know the mod list is of the type FMLHandshakeMessage.ModList, and is sent in a FMLHandshakeMessage. Can I access the data in this packet when it is received?



Check out my mod, Realms of Chaos, here.

You should be able to do this via a custom network check handler (see the NetworkCheckHandler annotation). In your handler, you can access the Map<String, String> which is a map of mod id to version from the connecting side and check if contains the Cheating Essentials mod ID.

Don't make mods if you don't know Java.

The client is a lying, cheating bastard.  If Cheat Essentials doesn't report itself to the server as being installed, you can't do a damn thing about it.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
