Code [Share]De-Level-Manager (+Level Choice)

`Heroin · April 16, 2013

Hi there for one more time, i made this npc today because i can see there are lots of npc like this but there is not any like this i made today. It is just an NPC where player can choose what level would like to be. Price is being regulated automatically like that: Number_of_levels_decreased * Configurable_price.

E.g: Player is 85 level, he chooses to be 70. His payment would be 15(levels) * code_price.

Preview (HTM Dialog):

How to install:

1. Create a new java file on data/scripts/custom/DeLevelManager/DeLevelManager.java

Paste this code:

package custom.DeLevelManager;
import com.l2jserver.gameserver.cache.HtmCache;
import com.l2jserver.gameserver.datatables.ItemTable;
import com.l2jserver.gameserver.model.L2Skill;
import com.l2jserver.gameserver.model.actor.L2Npc;
import com.l2jserver.gameserver.model.actor.instance.L2PcInstance;
import com.l2jserver.gameserver.model.quest.Quest;
import com.l2jserver.gameserver.network.serverpackets.ExBrExtraUserInfo;
import com.l2jserver.gameserver.network.serverpackets.NpcHtmlMessage;
import com.l2jserver.gameserver.network.serverpackets.UserInfo;

/**

*/
public class DeLevelManager extends Quest
{
private static final int npcid = 36650; // npc id
private static final int MinLevel = 10; // Minimum Level, (e.g if you set 10, players wont be able to be level 9).
private static final int ItemConsumeId = 57; // Item Consume id
private int levels ; // Item Consume id
private static final int ItemConsumeNumEveryLevel = 100; // Item ItemConsumeNumEveryLevel
private static String htm = "data/scripts/custom/DeLevelManager/1.htm"; //html location
private static String ItemName = ItemTable.getInstance().createDummyItem(ItemConsumeId).getItemName();

public DeLevelManager(int questId, String name, String descr)
{
	super(questId, name, descr);
	addFirstTalkId(npcid);
	addTalkId(npcid);
	addStartNpc(npcid);
}

@Override
public String onAdvEvent(String event, L2Npc npc, L2PcInstance player)
{
	if (event.startsWith("dlvl"))
	{
		Dlvl(event, npc, player, event);
	}

	return "";
}

private void Dlvl(String event, L2Npc npc, L2PcInstance player, String command)
{

	try
	{
		String val = command.substring(5);
		int pointer = Integer.parseInt(val);
		int k = player.getLevel();
		levels = k - pointer;
		if (player.getInventory().getItemByItemId(ItemConsumeId) == null)
		{
			player.sendMessage("You don't have enough items!");
			return;
		}
		if (val == null)
		{
			player.sendMessage("Something went wrong!");
			return;
		}
		if (pointer < 10)
		{
			player.sendMessage("Incorrect Level Number!");
			return;
		}
		if (pointer < MinLevel)
		{
			player.sendMessage("Incorrect Level Number!");
			return;
		}
		if (player.getLevel() <= pointer)
		{
			player.sendMessage("Your level is already lower.");
			return;
		}
		if (player.getInventory().getItemByItemId(ItemConsumeId).getCount() < ItemConsumeNumEveryLevel*levels)
		{

			player.sendMessage("You don't have enough items!");
			return;
		}
		if (player.getInventory().getItemByItemId(ItemConsumeId).getCount() >= ItemConsumeNumEveryLevel)
		{
			k = player.getLevel();
			final byte lvl = Byte.parseByte(pointer + "");	
			player.getStat().setLevel(lvl);
			player.sendMessage("Congratulations! You are now "+pointer+" level.");
			for(L2Skill sk : player.getAllSkills())
			{
				player.removeSkill(sk);
			}
			player.broadcastStatusUpdate();
			player.broadcastUserInfo();
			player.sendPacket(new UserInfo(player));
			player.sendPacket(new ExBrExtraUserInfo(player));
			player.giveAvailableAutoGetSkills();
			player.giveAvailableSkills(true, true);
			player.sendSkillList();
			levels = k - pointer;
			player.destroyItemByItemId("DlvlManager", ItemConsumeId, ItemConsumeNumEveryLevel*levels, player, true);
		}
	}
	catch (Exception e)
	{
		player.sendMessage("Something went wrong try again.");
	}
}



@Override
public String onFirstTalk(L2Npc npc, L2PcInstance player)
{
	final int npcId = npc.getNpcId();
	if (player.getQuestState(getName()) == null)
	{
		newQuestState(player);
	}
	if (npcId == npcid)
	{
		String html = HtmCache.getInstance().getHtm(player.getHtmlPrefix(), htm);
		html = html.replaceAll("%player%", player.getName());
		html = html.replaceAll("%itemname%", ItemName);
		html = html.replaceAll("%price%", ""+ItemConsumeNumEveryLevel+"");

		NpcHtmlMessage npcHtml = new NpcHtmlMessage(0);
		npcHtml.setHtml(html);
		player.sendPacket(npcHtml);
	}
	return "";
}

public static void main(final String[] args)
{
	new DeLevelManager(-1, DeLevelManager.class.getSimpleName(), "custom");
	System.out.println("De Level Manager by `Heroin has been loaded successfully!");
}
}

2.Create a new htm file on data/scripts/custom/HeroManager/1.htm

Paste this code on it.

<html>
<title>%player%</title>
<body><center>
<img src="L2UI_CH3.herotower_deco" width=256 height=32></center><br>
Hello there, if you want to low your current level, you came to right place!<br>
You have just to choose the <font color=FF0000>number</font> of level you would like to be.<br>
In exchange, i am going to take you <font color=LEVEL>%price% %itemname%</font> for <font color=LEVEL>each level
</font> you decrease.<br>
Remember: You can't choose a number higher than your current level.<br>

<table width=270><tr>
<td><button value="Change my level to: " action="bypass -h Quest DeLevelManager dlvl $lv" width=180 height=21 back="L2UI_CT1.Button_DF_Down" fore="L2UI_CT1.Button_DF"></td>
<td><edit var="lv" width=50></td>
</tr></table>


<br><br><br><br>
<center>
<img src="L2UI_CH3.herotower_deco" width=256 height=32></center>
</body></html>

3. Add script on scripts.cfg file:

custom/DeLevelManager/DeLevelManager.java

4. Run this query on your database or install the NPC by yourself.

INSERT INTO `custom_npc` VALUES ('36650', '13173', 'DeLevelManager', '1', 'MaxCheaters.com', '1', 'LineageNPC.clear_npc', '8.00', '19.00', '85', 'male', 'L2Npc', null, null, null, null, null, '40', '43', '30', '21', '20', '20', '0', '0', null, null, null, null, '230', '1', '0', '333', '0', '0', '0', '60.00000', '120.00000', '1', '1', '0', '0');

How to Modify:

Check Variables on code:

private static final int npcid = 36650; // npc id
private static final int MinLevel = 10; // Minimum Level, (e.g if you set 10, players wont be able to be level 9).
private static final int ItemConsumeId = 57; // Item Consume id
private int levels ; // Item Consume id
private static final int ItemConsumeNumEveryLevel = 100; // Item ItemConsumeNumEveryLevel
private static String htm = "data/scripts/custom/DeLevelManager/1.htm"; //html location

Is d-lvl a new idea? Hah

Is d-lvl a new idea? Hah

We all know that the de-level its one click from admin panel.

He made a npc for that so I found it new.

PS: I've never seen such as these shares so?

Dev · April 26, 2013

An easy share that didn't take you more than 15 mins to create it. Also the actual meaning of your share is trash. What means choose what level you want to be ? Rofl

I don't know much from L2 but I find it kewl.

So this is my explanation.

You know he is the only who sharing things that are not shared again. That's why.

I shared it for people who like to download this. You dont like, noone told you to download it. However, all other de-level manager don't work like that. If someone want be 40 level to kill AQ will need to decrease his level one-by-one? With this will be with 1 button in 1 min and pay for 40 levels he lost.

Hi, i have little problem, some fix?

----------
1. ERROR in /DeLevelManager.java (at line 99)
player.giveAvailableAutoGetSkills();
       ^^^^^^^^^^^^^^^^^^^^^^^^^^
The method giveAvailableAutoGetSkills() is undefined for the type L2PcInstance
----------
2. ERROR in /DeLevelManager.java (at line 100)
player.giveAvailableSkills(true, true);
       ^^^^^^^^^^^^^^^^^^^
The method giveAvailableSkills() in the type L2PcInstance is not applicable for the arguments (boolean, boolean)
