What is EntityJoinWorldEvent. I never use this class. How does it work? the NBT tag does not suffice because the client needs access to the data also. for my mistake I think I understand where the problem was. When a player logged in, I add datawatcher to the player but I don't add to the other player.I think, I should add this to all players on the server but I do not know how? Edit:I finally succeeded in using packets that are activated when a player connects and sends the list of players already present on the server, who just logged in

I read this topic (http://www.minecraftforge.net/forum/index.php/topic,6192.0.html) , I managed to "declare my fields" but I can't retrieve a value from another player (I have a Null PointerException)

Hello community forge, I need your advice. I need to add the class EntityPlayer a field, but I do not want to modify this class. I visited the wiki and I came across the tutorial on Access Transformer, but it doesn't explain how to add a new field to a class of minecraft How do I add my field to this class?
