Code .combinetalismans (High Five)

[Solomun]

Hello guys. Last night i found some time to spend in Lineage coding. After a while i decided that i would like to share something with you but i didn't know what, so i figured that there is not a .combinetalismans command shared. I know it is not something special, or hard to do, but since it hasn't been shared before, why not? :) It is coded for L2J HighFive but it can easily be adapted for any pack.

 

I will give full guide on how to install it, in order to avoid future posts like "i have this error" or "how do i fix that?" and bla bla.

 

It is very easy to install it. You need to make small changes to core and add a new .java file to your datapack. Read the steps below:

 

1. Head to com.l2jserver.gameserver.model.items.instance.L2ItemInstance and add the following lines anywhere to your code (just not in any other method).

 

 

/**
  * Method used by .combinetalismans.
  * @param value
  */
public void setMana(int value)
{
  _mana = value;
}

 

 

2. Create  CombineTalismans.java file to game\data\scripts\handlers\voicedcommandhandlers and add the following code in it.
