Help with restricted item in TvT

herneh · May 4, 2011

Hello there developers! my name is herneh,

Rev: L2Jserver Freya

I would like to restrict an item while in events "tvt" in this particular case, the item is "20399 labored Hat Blessed Body" i tried all I could but I havent got it yet! thats why I need your hel, I know that it would be an easy question for you, but i tried modifiing UseItem.java, TvTEvent.java adding the item restriction and I still didnt get it.

I would be apreciate wheter you give me a clue or a solution

Txz to all developers!

Bye

(EDIT) the revision

in useItem.java you need to make check like

if(itemid == 20399 && player.isInTvt()){return;}

I'm going to ask you for a final question...

If I want to UNEQUIP this item, when i'm being teletransported to TvTEvent, I would have modify TvTEvent.java right? smth like unequip item when being teletransported to olympiad stadium?

vampir · May 6, 2011

ye, thats the same, just copy paste :)

herneh · May 6, 2011

I used to "work" with java when I had gracia 1 so as u've noticed Im not an expert in java, but i'm pretty sure that the code might be in TvTEventTeleporter.java

I couldnt find the unequip section in olympiad.java :S

here's my tvteventteleported.java perhaps i'm wrong cause i dont know too much about java, but i thing it shud be here the uneequip command

Here it is!!! i got it! ;)

I dunno if it right but works!

in L2PcInstance

for (int i = 0; i < Inventory.PAPERDOLL_TOTALSLOTS; i++)

{

- L2ItemInstance equippedItem = getInventory().getPaperdollItem(i);

- if (equippedItem != null && (!equippedItem.getItem().checkCondition(this, this, false)

- || (isInOlympiadMode() && equippedItem.isOlyRestrictedItem())))

+ L2ItemInstance equippedItem = getInventory().getPaperdollItem(i);

+ if (equippedItem != null && (!equippedItem.getItem().checkCondition(this, this, false)

+ || (isInOlympiadMode() || (TvTEvent.isPlayerParticipant(getObjectId()) && equippedItem.isOlyRestrictedItem()))))

{

getInventory().unEquipItemInSlot(i);

And of course I added the item 20399 in restrictions olimpyad.properties

Txz man for helping me and guied me ;)
