Hi again,
Let's say I have such part of code, where I'm checking for an item DEFINED in config file:

Code: Select all

 if(player.getInventory().getItemByItemId(Config.NEEDED_ITEM) == null) {player.sendMessage("You run out of " + //and bump... );	return;}

Is it possible to check for player's item names without "looking" into his inventory? (I won't even try -> an obvious nullpointer will appear IMHO)

I can get that item name from DB, but the questions are:
1. Is it effective?
2. How to pull out a single string from DB, let's say I have a custom method like this:

Code: Select all

 public final String GetItemNameFromDB(){	String itemName = new String();	try	{		Connection conn = L2DatabaseFactory.getInstance().getConnection();		PreparedStatement statement =  conn.prepareStatement("SELECT name FROM etcitem WHERE item_id = " + Config.NEEDED_ITEM);		ResultSet rset = statement.executeQuery(); 		itemName = //... now, how to get that string? 		conn.close();		statement.close();	}	catch(SQLException e)	{		e.printStackTrace();	}	return itemName;}

If I'm doing it completely wrong please give me a hint how to catch up with it.
Thx in advance
Tom

check com.l2jserver.gameserver.datatables.ItemTable.getTemplate(int id) method.

thx JIV,
I had some probs with that method you mentioned about, but now everything is clear to me (eureka step by step) - since getTemplate(int id) method is non-static I needed to create a new instance of ItemTable class and refer through it to that non-static method getTemplate(int id) - something like this:

Code: Select all

 ItemTable xxx = new ItemTable();  //needed to change also the ItemTable constructor to publicxxx.getTemplate(Config.SCHEME_BUFF_CURRENCY).getName();

Instead of this I did it as follow:

Code: Select all

 ItemTable.getInstance().createDummyItem(Config.SCHEME_BUFF_CURRENCY).getName();

But here I'm doing the same thing as above + an extra usage of memory for dummy item w/o changing the visibility of class constructor...

Concluding I finally got it (i guess):

Code: Select all

 ItemTable.getInstance().getTemplate(Config.SCHEME_BUFF_CURRENCY).getName()

Correct me if I'm wrong, sorry for this bunch of "personal thoughts" and thx again JIV

Code: Select all

ItemTable.getInstance().getTemplate(Config.SCHEME_BUFF_CURRENCY).getName()

is correct and do not create new instance of itemtable.
