Hello! Today, I made my second code!

 

It's an item, which gives you Donator's Status.

 

The id of the item is 6673, if you want change it.

Dude, it's my first try in java. I don't know to make 'super' things, but with the time I will learn more and more.

 

I will try, to make something new. Thanks!

Yeah! I Have it at my server. :)

Are you sure? Show me the config or the code.

 

I searched l2jfrozen's source and there isn't any code about this item.

 

Waiting proofs.

I had it at my server.

C:\server\gameserver\config\functions\l2jfrozen.properties

# -----------------------------------------------------
# Donator Custom Item Configuration -
# -----------------------------------------------------
# When ActiveChar will use this item will be Donator.
EnableDonatorCustomItem = True
# Id Item Need's 
DonatorCustomItemId = 6673

YOU passed it. In retail l2jfrozen this code isn't exist.

 


 

http://subversion.assembla.com/svn/L2jFrozenInterlude/trunk/gameserver/config/functions/l2jfrozen.properties -> Current Revision (l2jfrozen.properties)

 


I don't have source. I don't use eclipse because I don't understand how to do it.
