Help Raking pvp/pk in Community Board custom /mobius c6 ct0

ak4n1 · March 16, 2024

Hello everyone,

I hope you're all having a good afternoon. I wanted to ask for your help with an issue I've been having while trying to create a community board for the Interlude chronicle using the L2JMobius CT 0 Interlude datapack. My goal is to make a top PvP and PK ranking and implement it into the custom community board that comes with this datapack.

I've adapted some code that works with the Interlude datapack from L2JMobius which I found in this link: Link. The creator of this code is "StinkyMadness".

Continuing on, I've created the RankingsBoard class and added it into the MasterHandlers, but the client throws a critical error. No errors are shown in the game server.

One idea that occurred to me is to implement this method in HomeBoard.java, but it also encounters the same error in the client. Since there are no errors shown in the game server, I'm having trouble finding a solution.

I would greatly appreciate any help or suggestions you can offer. Thank you in advance!

Here class RankingsBoard

Here the method implemented in the HomeBoard.java class in an else if, I do not put the entire class because it is very large and I think it is unnecessary, but the constants it uses

You can easily analyze it with l2phx, just check latest packets sent from game server to client.
