Message On The Screen After Enchant


Hyo
 Share

Question

Is there any way to do that using java to enchant an item leaves a message on the screen saying the chanse of success ?

 

like "you have X% chance to enchant your item"

 

im use l2jServer high five

 

Looking I found that should edit the "RequestExTryToPutEnchantTargetItem.java"

But exactly who should edit to make it work ?

package com.l2jserver.gameserver.network.clientpackets;

import java.util.logging.Level;

import com.l2jserver.gameserver.datatables.EnchantItemData;
import com.l2jserver.gameserver.model.EnchantScroll;
import com.l2jserver.gameserver.model.actor.instance.L2PcInstance;
import com.l2jserver.gameserver.model.items.instance.L2ItemInstance;
import com.l2jserver.gameserver.network.SystemMessageId;
import com.l2jserver.gameserver.network.serverpackets.ExPutEnchantTargetItemResult;

/**
 * @author KenM
 */
public class RequestExTryToPutEnchantTargetItem extends L2GameClientPacket
{
	private static final String _C__D0_4C_REQUESTEXTRYTOPUTENCHANTTARGETITEM = "[C] D0:4C RequestExTryToPutEnchantTargetItem";
	
	private int _objectId = 0;
	
	@Override
	protected void readImpl()
	{
		_objectId = readD();
	}
	
	@Override
	protected void runImpl()
	{
		L2PcInstance activeChar = getClient().getActiveChar();
		
		if ((_objectId == 0) || (activeChar == null))
		{
			return;
		}
		
		if (activeChar.isEnchanting())
		{
			return;
		}
		
		L2ItemInstance item = activeChar.getInventory().getItemByObjectId(_objectId);
		L2ItemInstance scroll = activeChar.getActiveEnchantItem();
		
		if ((item == null) || (scroll == null))
		{
			return;
		}
		
		EnchantScroll scrollTemplate = EnchantItemData.getInstance().getEnchantScroll(scroll);
		if ((scrollTemplate == null) || !scrollTemplate.isValid(item))
		{
			activeChar.sendPacket(SystemMessageId.DOES_NOT_FIT_SCROLL_CONDITIONS);
			activeChar.setActiveEnchantItem(null);
			activeChar.sendPacket(new ExPutEnchantTargetItemResult(0));
			if (scrollTemplate == null)
			{
				_log.log(Level.WARNING, getClass().getSimpleName() + ": Undefined scroll have been used id: " + scroll.getItemId());
			}
			return;
		}
		activeChar.setIsEnchanting(true);
		activeChar.setActiveEnchantTimestamp(System.currentTimeMillis());
		activeChar.sendPacket(new ExPutEnchantTargetItemResult(_objectId));
	}
	
	@Override
	public String getType()
	{
		return _C__D0_4C_REQUESTEXTRYTOPUTENCHANTTARGETITEM;
	}
}

Problem solved

 

I edit my RequestExTryToPutEnchantTargetItem.java

package com.l2jserver.gameserver.network.clientpackets;

import com.l2jserver.gameserver.network.SystemMessageId;
import com.l2jserver.gameserver.network.serverpackets.ExPutEnchantTargetItemResult;
++ import com.l2jserver.gameserver.network.serverpackets.ExShowScreenMessage;

/**

public class RequestExTryToPutEnchantTargetItem extends L2GameClientPacket
{
	private static final String _C__D0_4C_REQUESTEXTRYTOPUTENCHANTTARGETITEM = "[C] D0:4C RequestExTryToPutEnchantTargetItem";

	private int _objectId = 0;

	@Override
	protected void readImpl()
	{
		_objectId = readD();
	}

	@Override
	protected void runImpl()
	{
		L2PcInstance activeChar = getClient().getActiveChar();

		if ((_objectId == 0) || (activeChar == null))
		{
			return;
		}

		if (activeChar.isEnchanting())
		{
			return;
		}

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

		if ((item == null) || (scroll == null))
		{
			return;
		}

		EnchantScroll scrollTemplate = EnchantItemData.getInstance().getEnchantScroll(scroll);
		if ((scrollTemplate == null) || !scrollTemplate.isValid(item))
		{
			activeChar.sendPacket(SystemMessageId.DOES_NOT_FIT_SCROLL_CONDITIONS);
			activeChar.setActiveEnchantItem(null);
			activeChar.sendPacket(new ExPutEnchantTargetItemResult(0));
			if (scrollTemplate == null)
			{
				_log.log(Level.WARNING, getClass().getSimpleName() + ": Undefined scroll have been used id: " + scroll.getItemId());
			}
			return;
		}
		activeChar.setIsEnchanting(true);
		++ double chance = scrollTemplate.getChance(item, null);
		++ activeChar.sendPacket(new ExShowScreenMessage("You have " + chance + "% chance of success!", 3000));
		activeChar.setActiveEnchantTimestamp(System.currentTimeMillis());
		activeChar.sendPacket(new ExPutEnchantTargetItemResult(_objectId));
	}

	@Override
	public String getType()
	{
		return _C__D0_4C_REQUESTEXTRYTOPUTENCHANTTARGETITEM;
	}
}

I was wrong about the RequestEnchantItem :lol:

You should send the ExShowScreenMessage with the EnchantScrolls handler which you can find in \data\scripts\handlers\itemhandlers

What's the point of those files? Add your code after

activeChar.sendPacket(new ChooseInventoryItem(item.getItemId()));

@ EnchantItem, so you will see the msg after pressing the scroll. It's 0.8 cuz on aCis the value is double ;)

Something like this..

activeChar.sendPacket(new ExShowScreenMessage("You have " + Config.ENCHANT_CHANCE_WEAPON + "% chance of success!", 6000));

Also put a check for the enchant type.. note that if you have different chances for armor and jewels, you should send the chances of the two types, because it doesn't recognize what you want to enchant :)

i edit my itemhandlers/enchantscroll.java

package handlers.itemhandlers;

import com.l2jserver.gameserver.handler.IItemHandler;
import com.l2jserver.gameserver.model.actor.L2Playable;
import com.l2jserver.gameserver.model.actor.instance.L2PcInstance;
import com.l2jserver.gameserver.model.items.instance.L2ItemInstance;
+ import com.l2jserver.gameserver.network.serverpackets.ExShowScreenMessage;
import com.l2jserver.gameserver.network.SystemMessageId;
import com.l2jserver.gameserver.network.serverpackets.ChooseInventoryItem;

public class EnchantScrolls implements IItemHandler
{
	@Override
	public boolean useItem(L2Playable playable, L2ItemInstance item, boolean forceUse)
	{
		if (!playable.isPlayer())
		{
			playable.sendPacket(SystemMessageId.ITEM_NOT_FOR_PETS);
			return false;
		}
		
		final L2PcInstance activeChar = playable.getActingPlayer();
		if (activeChar.isCastingNow())
		{
			return false;
		}
		
		if (activeChar.isEnchanting())
		{
			activeChar.sendPacket(SystemMessageId.ENCHANTMENT_ALREADY_IN_PROGRESS);
			return false;
		}
		
		activeChar.setActiveEnchantItem(item);
		+ activeChar.sendPacket(new ExShowScreenMessage("You have " + Config.ENCHANT_CHANCE + "% chance of success!", 6000));
		activeChar.sendPacket(new ChooseInventoryItem(item.getItemId()));
		return true;
	}
}

Note: i use the same enchant chance for armors,weaps and jewels.

 

And i take this error in the gameserver console :(
