Try this:

 

    
       int weaponGrade = activeChar.getActiveWeaponItem().getCrystalType();
       int armorGrade = activeChar.getActiveChestArmorItem().getCrystalType();
-      if (activeChar.isInOlympiadMode() && (weaponGrade == L2Item.CRYSTAL_S || armorGrade == L2Item.CRYSTAL_S))

Change this:

if (activeChar.isInOlympiadMode() && (weaponGrade != null || armorGrade != null)

To:

if (activeChar.isInOlympiadMode() && (weaponGrade != null || armorGrade != null))

 

My fault :P

        int lolz0r = item.getItem().getCrystalType();
        if (activeChar.isInOlympiadMode() && lolz0r == L2Item.CRYSTAL_S)

        	//to do...

It say---> item cannot be resolved

 

int lolz0r = item.getItem().getCrystalType();

             ^^^

It say---> item cannot be resolved

 

int lolz0r = item.getItem().getCrystalType();

             ^^^

 

Add it below this: L2ItemInstance item = activeChar.getInventory().getItemByObjectId(_objectId);

[manos2864]

+     

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

+      if (activeChar.isInOlympiadMode() && (weaponGrade == L2Item.CRYSTAL_S || armorGrade == L2Item.CRYSTAL_S))

+      {

+        activeChar.sendMessage("You cannot use S grade equipment at the Grand Olympiad games.");

Put in UseItem :\

       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;
       }

Yes i do it ... but it say item cannot be resolved...

int lolz0r = item.getItem().getCrystalType();

             ^^^

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);
