public static int isUpdateAvailable() 
	try {

		BufferedReader versionFile = new BufferedReader(new InputStreamReader(new URL(urlString).openStream()));

"Hentai" - Dat Mod :)


I am guessing you are executing this class in preInit?


There are 3 ways:

1. Subscribe to PlayerLoggedInEvent.

- This even is only fired by Server thread.

- Send packet that tells player to display his LOCAL version.


2. Subscribe to PlayerLoggedInEvent.

- This even is only fired by Server thread.

- Send ChatComponent containing mod version this Server thread is running on (you know, client must have same version as server, so it's right to assume that client will have same as server). Note: doesn't matter is you are SP or MP.


3. Do everything on Client thread:

- Subscribe to EntityJoinedWorld and make it run only Client side (world.isRemote)

- Check if entity == mc.thePlayer (your player entity)

- Print ChatComonent client-side.


#3rd one is best.

1.7.10 is no longer supported by forge, you are on your own.
