How can I know if a player unlocked an achievement? The achievement is from minecraft, not custom by me.

I don't need it for a server.

I don't need it for a server.

 

There are two sides in Minecraft (even on Singleplayer) the Client and the Server.

The client is basically everything the player does, and the server is what the "world" does (achievements, generation, item drops, etc.)

It crashes Minecraft. I suppose I did a stupid mistake. Can you help me?

 

EntityPlayerMP playerMP = (EntityPlayerMP) event.player;

if (playerMP.func_147099_x().hasAchievementUnlocked(AchievementList.enchantments))

System.out.println("MERGE!!!!!!!!!");

I use PlayerTickEvent . I think I use a wrong event. The crash report is here:
