Well, hello. I got borred of those clumsy npc buffers, so I made my own instanced buffer.

 

I made it for aCis project server pack, but it can be easly adapted for another pack.  8)

 

Create L2BufferInstance.java and put in it the code:

    }
}

 

Put L2BufferInstance.java file into

java/net/sf/l2j/gameserver/model/actor/instance/

 

Now create new npc with id 99 or whatever you want and set type to L2Buffer.

That's all. Now spawn your npc and enjoy. :D

 

P.s I hate htmls, so I made buffer dialog inside L2BufferInstance.

Put L2BufferInstance.java file into

java/net/sf/l2j/gameserver/model/actor/instance/

 

Now create new npc with id 99 or whatever you want and set type to L2Buffer.

That's all. Now spawn your npc and enjoy. :D

 

P.s I hate htmls, so I made buffer dialog inside L2BufferInstance.

 

Screenshot:

you got some errors in checks... they can do buffs while they are in combat-sitting bla-bla... 1)you can make a private void

 

private void showMessageError(L2PcInstance player)
    {
	NpcHtmlMessage html = new NpcHtmlMessage(1);
	final StringBuilder strBuffer = StringUtil.startAppend(3500, "<html><title>Magician</title><body><center>");
    {
		strBuffer.append("<img src=\"L2UI_CH3.onscrmsg_pattern01_2\" width=300 height=32 align=left>");
		 strBuffer.append("<font color=\"LEVEL\">%charname%</font>You can't buff right now!:<br>");
		strBuffer.append("<table width=300>");
		strBuffer.append("</table><img src=\"L2UI_CH3.onscrmsg_pattern01_2\" width=300 height=32 align=left>");
    }
	strBuffer.append("</center></body></html>");
	html.setHtml(strBuffer.toString());
	html.replace("%objectId%", String.valueOf(getObjectId()));
	html.replace("%charname%", player.getName());
	player.sendPacket(html);
    }

and then send the message like this

 

if (player.isSitting())
        {
        	player.sendMessage("You can't use buffer while you're sitting.");
        	showMessageError(player);
	    return;
	}

 

2) you can make the same for all checks... px: make voids for all checks

 

private void showMessageErrorSitting(L2PcInstance player)
    {
	NpcHtmlMessage html = new NpcHtmlMessage(1);
	final StringBuilder strBuffer = StringUtil.startAppend(3500, "<html><title>Magician</title><body><center>");
    {
		strBuffer.append("<img src=\"L2UI_CH3.onscrmsg_pattern01_2\" width=300 height=32 align=left>");
		 strBuffer.append("<font color=\"LEVEL\">%charname%</font> You can't buff while sitting!:<br>");
		strBuffer.append("<table width=300>");
		strBuffer.append("</table><img src=\"L2UI_CH3.onscrmsg_pattern01_2\" width=300 height=32 align=left>");
    }
	strBuffer.append("</center></body></html>");
	html.setHtml(strBuffer.toString());
	html.replace("%objectId%", String.valueOf(getObjectId()));
	html.replace("%charname%", player.getName());
	player.sendPacket(html);
    }

 

if (player.isSitting())

        {
        	showMessageErrorSitting(player);
	    return;
	}

@AbSoLuTePoWeR, I wanted to make a simple buffer as possible, with less code as possible. Also my checks working very well, if you aren't using l2phx to send bypasses directly.

 

But thanks for your suggestion. :)

 

EDIT: It seems, that on l2jfrozen my checks not working properly. :)

 

In l2jfrozen, player.isInCombat() working only if you attacking someone, not someone attacking you.

On aCis my checks works without any problems. :) I have refactored l2jfrozen isInCombat check and it now works on l2jfrozen too. :P

 

EDIT: Well, I'll make more advanced buffer when I'll have more time. With configs and other stuff bla bla bla. :P
