omg, show us your UseItem.java www.pastebin.com

manos2864 · July 11, 2010

It's already defined

protected void runImpl()

{

L2PcInstance activeChar = getClient().getActiveChar();

if (activeChar == null)

return;

if (activeChar.getPrivateStoreType() != 0)

{

activeChar.sendPacket(new SystemMessage(SystemMessageId.CANNOT_TRADE_DISCARD_DROP_ITEM_WHILE_IN_SHOPMODE));

activeChar.sendPacket(new ActionFailed());

return;

}

L2ItemInstance item = activeChar.getInventory().getItemByObjectId(_objectId);

When i put this code ..... in line 106 say duplicate local variable item -->

L2ItemInstance item=activeChar.getInventory().getItemByObjectId(_objectId);

Edit

Here my useitem.java (Original) --> http://pastebin.com/5WY4ZVKs

Maaan,this variable is few lines below,it alrdy exists,dont add it again!

Just add the code below that line. >_>

         if (activeChar.getActiveTradeList() != null)
		activeChar.cancelActiveTrade();

	// NOTE: disabled due to deadlocks
	// synchronized (activeChar.getInventory())
	// 	{
		L2ItemInstance item = activeChar.getInventory().getItemByObjectId(_objectId);

		if (item == null)
                               return;

+                      int lolz0r = item.getItem().getCrystalType();
+                      if (activeChar.isInOlympiadMode() && lolz0r == L2Item.CRYSTAL_S)
+                      {
+        	               activeChar.sendMessage("You cannot use S grade equipment at the Grand Olympiad games.");
+                              return;
+                      }

		if (item.isWear())
		{
			// No unequipping wear-items
			return;
		}

i will add only this code??

i will add only this code??

since you asked this i assume you dont know how your pack works so little explanation

long ago l2j implemented a system when they unhardcoded item checks(condition value in xml files)

and here what they did is they added a general item check for items with Y condition

hence the isOlyRestrictedItem() method is a part of this...it indicates to a list of items that you CANT use on olympiad and its alredy working fine...and if you check how its called you can see if its return true the item is olympiad restricted if its return false than its allowed to use...imho a grade check with return truw value in this method block items stated in the if statement
