Code Remove Buffs And Debuffs Item

te0x · July 3, 2014

so in frozen there is a gm command that shows u ur buffs/debuffs and u can cancel em by pressing remove.

so i did that for the players. u press a item and a html shows up with all ur bufflist and u are able to remove any buff that u want.

i made it with an item press cauze i had smthing else in my mind but u can make it with command ;d

so.

    		if (!activeChar.getFloodProtectors().getDropItem().tryPerformAction("Use"))
    		{
    			activeChar.sendPacket(ActionFailed.STATIC_PACKET);
    			return;
    		}

				if(activeChar.getKarma() > 0 || activeChar.getPvpFlag() > 0 || activeChar.isInCombat())
				{
					activeChar.sendMessage("You cannot use the bufflist view right now");
					return;
				}
				
				if(activeChar.isInOlympiadMode() || activeChar.getOlympiadGameId() != -1)

			else
			{
		    	   showBuffs(activeChar, activeChar);
			}
			activeChar = null;
		}
	
   	public void showBuffs(L2PcInstance player, L2PcInstance activeChar)
	{

	}

	@Override
	public int[] getItemIds()
	{
		return ITEM_IDS;
	}

	private static final int ITEM_IDS[] =
	{
		6392
	};

}

now network/clientpacks/RequestBypassToServer.java

find this

			else if (_command.startsWith("OlympiadArenaChange"))
			{
				Olympiad.bypassChangeArena(_command, activeChar);
			}

below add

			if (_command.startsWith("stopbuff"))
			{
				StringTokenizer st = new StringTokenizer(_command);
				st.nextToken();
				try
				{
					if(st.hasMoreTokens())
					{
						String playername = st.nextToken();

						if(st.hasMoreTokens()){
							
							int SkillId = 0;
							
							try{
								SkillId = Integer.parseInt(st.nextToken());

							}catch(NumberFormatException e){

								return;
								
							}
							
							if(SkillId>0)
								removeBuff(activeChar, playername, SkillId);
							else{
								return;
							}
							
							st = null;
							playername = null;

							return;
							
							
						}
						return;
					}
					return;
				}
				catch (StringIndexOutOfBoundsException e)
				{
				}
			}

now find private void comeHere(L2PcInstance activeChar) and above add the code

	public void showBuffs(L2PcInstance player, L2PcInstance activeChar)
	{
		
		if(activeChar.getKarma() > 0 || activeChar.getPvpFlag() > 0 || activeChar.isInCombat())

			return;
		}
		
		if(activeChar.isInOlympiadMode() || activeChar.getOlympiadGameId() != -1)
		{
			activeChar.sendMessage("You cannot use the bufflist view right now");
			return;
		}
		
		TextBuilder html = new TextBuilder();

		html.append("<html><head><title>Character Buffs</title></head>");
		html.append("<body>");      
		html.append("<center>");
		html.append("<table width=\"250\" cellpadding=\"5\" bgcolor=\"999999\">");
		html.append("<tr>");
		html.append("<td align=\"center\"><font color=\"FF4400\">My buff list</font>");

		activeChar.sendPacket(ms);

		html = null;
		ms = null;
		effects = null;
	}
	
	private void removeBuff(L2PcInstance remover, String playername, int SkillId)
	{
		L2PcInstance player = L2World.getInstance().getPlayer(playername);
		
		if(player.getKarma() > 0 || player.getPvpFlag() > 0 || player.isInCombat())
		{
			player.sendMessage("You cannot remove buffs right now");
			return;
		}

			{
				if(e != null && e.getSkill().getId() == SkillId)
				{
					e.exit(true);
				}
			}
			showBuffs(player, remover);

			player = null;
			effects = null;
