Recommended Posts

Hello.

 

I have one problem, that everytime when I am on a server and then switch from surface to the nether, a ClassNotFoundException occurs, on Client in SP everything works fine.

 

I'm using Forge 1.7.2-10.12.1.1103.

 

Here is the error and the code:

The ChangeDimensionEvent is server-side only.

To get the "StatisticsFile", which controls the achievements, from the player, cast to EntityPlayerMP (which is save, because its server-code) and call func_147099_x, which gives you the StatisticsFile.

Then you can call hasAchievementUnlocked on that.

Ok, thanks.

I think its now fixed. (Well I didn't test it yet, but I will test it today, so that if that doesn't fix this issue, I will reply here back...)
