[116] Ciphra/Lithium Block/Edit Cash item with out WZ edit

[Chikn]

Hi.
I've played in Extalia and see they block items from the CS without editing WZ. And after a dozen times tried & failed. I have figured out how it work.

Here is my CasItemFactory.java.

And you can see. I load a list of items from the database. This is the information about the items that I want to change in CS. You can change everything like price, period, priority, ...

[ngnam87]

look in GameConstants
param cashBlock

[Chikn]

It completely removed in CS. You can't see, search, buy blocked item and look more professional (lmao). Not that way

[kevintjuh93]

Do these sources have the packet parts already?

Also it looks a bit the same with what I have in rev 121.

It's funny as I never knew that Lithium had it. Mine is directly from the client btw, just saw that Lithium was missing some part.
Oh and it's possible to add normal items to the cash shop too (you just have to do some coding for the buy part).

I tested it on CiphraDEV (the only one v116 i has) and i work fine =)
Oh. I didn't know that you can add normal items to the CS. I thought u can do it with newer version only.

[AristoCat]

I don't see what is this release for. The table was in database already, you only added a blacklist ini file which is not really needed?

+1, useless release.. :/

[AristoCat]

Isn't there a rule against spamming?

WTH happend to you? o_O

[Chikn]

I'm just testing and to lazy to change. So, bleh
Btw, which table are you talking about?

@itai5001: Just ignore if it useless with you. Kthxbye.
