how to parse npc from media.pk2 files

fakeheader · 03/03/2015, 07:48

Hello
I am working on a nice project but I neee help parsing npc data from the text files

I want to
get npc of each town from text files
get type of npc ... like blacksmith and etc
Get npc shop content

so can anyone help?

Check Zbot's source code. It grabs information from text files after being extracted from the media.pk2.

i did but its not working i need to make it generic for all servers and because some server has custom npc so i need to find a way to extract the content and the shop type

Then just loop them all with the Method of zBot , otherwise rewrite it du avoid the errors

well .... zbot has its static values for each town ... and it doesnt have alex npc ... anyway i solved the problem using the the expression ... like npc_wc_ so wc is western china then if the string have _smith then its black smith and thanks to fox564 for this solution, thanks for your time

Just load them from the client textdata it's not that hard.

Hint: don't use CodeName128 to parse anything.

Thank you for your answer but here is my problem
in zbot there is no alex npc in the parse and also you made other npc static
so what if the client have custom npc names how would I auto buy pots for example
thats why I need to make it generic

GGWP; You just wasted a lot of time.

1st: Parse SingleSpawn & GroupSpawn
You get, NPCObjectID, XYZ from them.

Then you need to load up a few txt files, get the item locations via this.

However, if you do find a better way to do this, go ahead and post it.

This is strictly speaking only for Type 8 @ 0xB034, since the rest is entirely different.
All those people making alchemy bots etc.. this is highly useful for you

EDIT: For shit like this:

Spoiler

First create this function

PHP Code:

CREATE FUNCTION _getTabIndex(@NPCID INT, @TabCodename VARCHAR(128)) RETURNS INT AS BEGIN DECLARE @Index INT; SELECT @Index = tabindex FROM ( SELECT ROW_NUMBER() OVER (ORDER BY tab.RefTabGroupCodeName ASC, tab.ID ASC)-1 tabindex, tab.CodeName128 FROM _RefShopTab tab JOIN _RefMappingShopWithTab maptab ON tab.RefTabGroupCodeName = maptab.RefTabGroupCodeName JOIN _RefShop shop ON maptab.RefShopCodeName = shop.CodeName128 JOIN _RefMappingShopGroup mapshop ON shop.CodeName128 = mapshop.RefShopCodeName JOIN _RefShopGroup shopgroup ON mapshop.RefShopGroupCodeName = shopgroup.CodeName128 JOIN _Refobjcommon R ON shopgroup.RefNPCCodeName = R.CodeName128 WHERE R.ID = @NPCID ) q WHERE q.CodeName128 = @TabCodename RETURN @Index END

Then run this and create your npcshoplist. You need to parse NPCs via single/groupspawn beforehand though, otherwise you cant get the NPC ID.

PHP Code:

SELECT npc.ID as NPCID,.dbo._getTabIndex(npc.ID,goods.RefTabCodeName) TabID, Item.id as ItemID, goods.SlotIndex ,scrap.Data FROM _RefShopGoods goods JOIN _RefShopTab tab ON goods.RefTabCodeName = tab.CodeName128 JOIN _RefMappingShopWithTab maptab ON tab.RefTabGroupCodeName = maptab.RefTabGroupCodeName JOIN _RefShop shop ON maptab.RefShopCodeName = shop.CodeName128 JOIN _RefMappingShopGroup mapgroup ON shop.CodeName128 = mapgroup.RefShopCodeName JOIN _RefShopGroup shopgroup ON mapgroup.RefShopGroupCodeName = shopgroup.CodeName128 JOIN _Refobjcommon npc ON shopgroup.RefNPCCodeName = npc.CodeName128 JOIN _RefPackageItem package ON goods.RefPackageItemCodeName = package.CodeName128 JOIN _RefScrapOfPackageItem scrap ON package.CodeName128 = scrap.RefPackageItemCodeName JOIN _Refobjcommon item ON scrap.RefItemCodeName = item.CodeName128 WHERE npc.ID = 2073 ORDER BY tab.RefTabGroupCodeName ASC, tab.ID ASC

THEN it would be properly dynamic. But you don't need anything like XYZ from CharData.txt

You can also use like royalblade says ParseSingleSpawn and if type is a NPC then build a function e.g ParseNPC
Old sro-r ParseNPC stuff

Code:

public static int ParseNPC(object opacket, object xresult, bool groupspawn)
{
	Packet packet = (Packet)opacket;
	SpawnData result = (SpawnData)xresult;
	int startpos = (int)packet.data.pointer - 4; 
	//try
	//{
		result.UniqueId = packet.data.ReadDWORD();

		result.xSec = packet.data.ReadBYTE();
		result.ySec = packet.data.ReadBYTE();
		result.X = packet.data.ReadSINGLE();
		result.Z = packet.data.ReadSINGLE();
		result.Y = packet.data.ReadSINGLE();
		packet.data.ReadWORD(); //angle

		result.XCoord = Functions.GetXCoord((int)result.X, result.xSec);
		result.YCoord = Functions.GetYCoord((int)result.Y, result.ySec);

		result.distance = Functions.CalcDistance(result.XCoord, result.YCoord);

		byte haveDest = packet.data.ReadBYTE();
		byte movingType = packet.data.ReadBYTE();
		if (haveDest == 0x01)
		{
			result.DestXSec = packet.data.ReadBYTE();
			result.DestYSec = packet.data.ReadBYTE();

			if (result.DestYSec == 0x80)
			{
				packet.data.ReadSignedDWORD();
				packet.data.ReadSignedDWORD();
				packet.data.ReadSignedDWORD();
			}
			else
			{
				result.DestX = packet.data.ReadSignedWORD();
				result.DestZ = packet.data.ReadSignedWORD();
				result.DestY = packet.data.ReadSignedWORD();
			}
		}
		else
		{
			packet.data.ReadBYTE();
			packet.data.ReadWORD();
		}


		result.DeathFlag = packet.data.ReadBYTE();
		packet.data.ReadBYTE(); //movement flag
		packet.data.ReadBYTE(); //berserk gauge
		packet.data.ReadBYTE(12); //walk speeds

		byte skillcount = packet.data.ReadBYTE();
		for (int s = 0; s < skillcount; s++)
		{
			uint skillid = Functions.ReverseNumber(packet.data.ReadDWORD()); // ID
			packet.data.ReadDWORD(); // SKILL UNIQUE ID

			foreach (SkillData sd in Main.Skills)
			{
				if (sd.ID == skillid)
				{
					if (Functions.extraByte(sd.pk2name) == true)
						packet.data.ReadBYTE();
					break;
				}
			}
		}

		byte action = packet.data.ReadBYTE();

		if (action == 2)
			packet.data.ReadDWORD();
		else if (action != 0x00)
			packet.data.ReadBYTE(packet.data.ReadBYTE());

		Main.UpdateSpawns(result, true);
	//}

	//catch
	//{
	//    string packetasstring = "S->C(" + packet.Opc.ToString("X4") + ") ";
	//    foreach (byte b in packet.ToByteArray())
	//    {
	//        packetasstring += b.ToString("X2");
	//    }


	//    System.IO.File.AppendAllText(System.Environment.CurrentDirectory + "\\err_npc.txt", packetasstring + "\r\n" + "Pos:" + packet.data.pointer.ToString() + " LEN:" + packet.data.len.ToString() + " START POS:" + startpos.ToString() + " MODEL:" + result.model.ToString("X8") + "\r\n");

	//}

	return packet.data.pointer;

}

Update 00:29
You can also parse it with the Media.pk2

Thanks alot

Devsome · 03/09/2015, 00:30

Just check my Update.
You're welcome, just don't copy & paste.
Try it on your own

fakeheader · 03/09/2015, 16:28

I have already made my single/group spawn parser functions
I will just try to modify your function and make it more dynamic
thanks again
