Help Christmas is approaching. Let's discuss the Xmas event NPC

[Kowalskiz]

I'm using Myext64 HF
and recently tried to replicate the "br_xmas09_event" Raising Rudolph Event.

Detailed event information can be found at https://legacy-lineage2.com/news/_rudolf_the_red.html

After configuring .eventdata.xml and starting the server, t

The NPC server sent a packet to the L2 server while generating the br_xmas2009_invisible game NPC server, and the NPC server subsequently crashed.

 

 

After some digging, I found a clue in a very old MXC post, but the fix was for the GF version.

The whole problem is in l2server side support for NPC function CreateOnePrivateNearUser. It sends CreatePacket but Koreans made some changes in it (added instance ID) so it got broken. As Santa event is the only AI that uses this function, they probably don't know about it 

 

So is there a way to fix this problem, specifically for Myext64 HF?

I'd be happy to buy him coffee.

Another one is about the " br_vitality2010_event event".

 

GIVE_EVENT_DATA is likely the only one in the activity AI script that uses this handle.
