If you want to put a big welcome message read this tutorial.
This is for l2jfree.
Eclipse. go to : src/main/java/come.l2jfree.gameserver.network/SystemMessageId.java
Here you need to add your custom message, in my example i will put 3 new message :
CUSTOM_MESSAGE_WELCOME(2602),
CUSTOM_MESSAGE_WELCOME2(2603),
CUSTOM_MESSAGE_WELCOME3(2604);
CUSTOM_MESSAGE_WELCOME3 - name and 2604 - id
Save the file and now go to com.l2jfree.gameserver/L2jFreeInfo.java
Here you will add your welcome message like this :
SystemMessage sm = new SystemMessage(SystemMessageId.CUSTOM_MESSAGE_WELCOME);
Announcements.getInstance().announceToAll(sm);
Now compile the l2jfree-core .
On the system folder decrypt systemmsg-e.dat and add this 3 lines.
2602 1 Welcome to our private lineage II server. 2 B09B79 8 0 3 1 0 Welcome here. server
2603 1 Welcome to our private lineage II server. 0 B09B79 8 0 5 1 0 Welcome here. none
2604 1 Welcome to our private lineage II server. 0 B09B79 2 0 10 1 0 Welcome little man. none
And now when you will enter the server you will see:
If you type: //msg 2604 you will see:
You can use this type of message in allot of things, you need only imagination.
