Guide Free help-Requests l2j

[SailFpO]

Hello all,

Since I love to help people if my knowledge can provide the solution, I'm here to help you with your requests/problems about l2j.
I'm usually on for 3-4 hours per day so don't expect fast respond.

• I'd love to create your idea and give you the code ready but get real, I wont spend hours for just one thing , so don't request something big
• Feel free to ask any thing you cant understand, blame is not allowed here :)
• I have no idea for anything related to client side.
• Atm I'm working on aCis project (feel free to ask something which is related to another project ).

 

Finally,

I want to do this because it will be useful (for some members) but for me too, I'm learning java and I would like to improve my skills so I found it great idea.

 

If this post is in wrong section please a mod move it to the proper one :) Thank you!

[SailFpO]

Take a look in your gameserver.java if there exists a line 'Quiz.getinstance()' , if you found it just add // or delete it

p.s. it could be with configs for enable/disable

Hey, maybe You could share Your buffer's code if You have one. I just hate scheme buffers.

Well I do not have anything because I'm not planning to open a server :P , you can find infinity buffers here in mxc especially without scheme options

You have to create a new folder in data/html/mods with name trader and inside create a new html with the npc id as name. (in my case was 50009), then paste the html code

You have to create a new folder in data/html/mods with name trader and inside create a new html with the npc id as name. (in my case was 50009), then paste the html code

Thank you.

[tazerman2]

you can make this 

<button value="exchange" action="bypass npc_%objectId%_exchange" height=15 width=45 back="sek.cbui94" fore="sek.cbui92">

as like this

<button value="exchange" action="bypass npc_%objectId%_exchange $count" height=15 width=45 back="sek.cbui94" fore="sek.cbui92">

for player dont need press all time 1 button with <edit var="$count" width=120 height=15> default conut = 1 if box is space

Well a good code must be secured too, Generally avoid to create codes that uses value from html because this one can be easily bypassed from programs like andrenaline...

Even in buffer case where the bypass is npc_%objectId%_buff 1204 2 can be bypassed to npc_%objectId%_buff 7029 4

and the user will get gm speed lvl 4...

 

p.s Ofc a code like you did with all necessary checks inside can be worked too without any problem but its a huge amount of wasted time :D

You could make it like

if (!player.destroyItemByItemId("ex", REQUIRE_ITEM_FOR_EX[0], REQUIRE_ITEM_FOR_EX[1], null, true))
    return;
	player.addItem("rew", REWARD_ITEM[0], REWARD_ITEM[1], null, true);

If destroyItem.. return false, you get the message about incorect item count. With your message, you get it twice.

Well, it's not twice :P if you look carefully

the default one inside of destroyitem.... is

if (sendMessage)
	sendPacket(SystemMessageId.NOT_ENOUGH_ITEMS);

which is the message "Incorrect item count." in the player's chat.

the second one (I added) is

SystemMessageId.NOT_ENOUGH_REQUIRED_ITEMS)

which is the message in dialog "You do not have enough required items." :D

I just like the dialog to appear when the player haven't all the required items. (it's just optional)

1) You have to create your own item handler

2) You need somewhere to save the value after the server restart. So add one more field in your items table in db to store the sp

3) if you are using acis , at restore() method of class Inventory add one more field in the statement where is loading the informations of items like :

"SELECT object_id, item_id, count, enchant_level, loc, loc_data, custom_type1, custom_type2, mana_left, time, SP FROM items WHERE owner_id=? AND (loc=? OR loc=?) ORDER BY loc_data

4) restoreFromDb() method add one more int 'sp' and handle it. example:

public static ItemInstance restoreFromDb(int ownerId, ResultSet rs)
 	{
 		ItemInstance inst = null;
-		int objectId, item_id, loc_data, enchant_level, custom_type1, custom_type2, manaLeft, count;

5) add the above methods and complete your request in your item handler something like that:

	@Override
	public void useItem(Playable playable, ItemInstance item, boolean forceUse)
	{
		if (!(playable instanceof Player))
			return;
		
		Player activeChar = (Player) playable;
		
		if (item.getSP() > 0)
		{
			activeChar.addExpAndSp(0, item.getSP());
			item.setSP(0, true);
			activeChar.destroyItem("SP", item, null, true);
		}
		else if (activeChar.getSp() > 0)
		{
			final int charSP = activeChar.getSp();
			activeChar.removeExpAndSp(0, charSP);
			item.setSP(charSP, true);
			activeChar.sendMessage(charSP + " saved!");
		}
		else
			activeChar.sendMessage("You do not have enough SP!");
	}
