If you read anything from the mpq files, you need to patch them first.

[bastiflew]

How do you "patch" mpq files ?

[azgul]

You can do it manually with MPQ Editor or programmatically with crystalmpq

[bastiflew]

Azgul, there's something that I don't understand, let's take a sample :

- in d3-update-base-21876.MPQ there's a scene file called x1_fortress_EW_02_B.scn (tag IsPatch to True)
- if I use CrystalMPQ to extract this file, I have a FileNotFoundException
- if I use MPQEditor, the file is properly extracted

How can I get this file properly extracted with CrystalMPQ ?

Thanks

[azgul]

You're doing it wrong, the d3-update-base-XXXX & d3-update-enUS-XXXX are patches. You should patch those onto the files in Data_D3\PC\MPQs (these are the base MPQs) depending on which data you need.

With MPQ Editor you'd have to press File -> Open MPQ(s) -> Custom Open MPQ.

So say you want to read all MPQs to apply the patches you should select all MPQs in Data_D3\PC\MPQs and then you will be met with the following dialogue: https://mediacru.sh/T60yxN5HKCRg
Then you have to right click under 'Patches' to add the MPQ patch files.

For examples of using crystalmpq I would look at mooege: https://github.com/DarkLotus/mooege/...ege/Common/MPQ

Thanks for hints. After a while i managed to patch localized strings using MPQEditor. Here is complete list if anyone is interested xD Localized item names - Pastebin.com

@azgul : thanks a lot, my extraction was wrong since the beggining !
Some scenes was weird sometime, it makes sense now

Thanks a lot for all the input from everyone!

I am trying to sell automatically and have a problem determining the size an ACD is occupying in the player inventory. In other words, how can I find out if a specific ACD takes 1x1 slots (e.g. a ring) or 1x2 slots (e.g. a weapon)?

@Enigma: here a small patch for ProcessMemoryReader.cs
_process = process;
_minValidAddress = 0x00010000;
- _maxValidAddress = process.IsLargeAddressAware() ? 0x7FFEFFFF : 0xBFFF0000;
+ _maxValidAddress = process.IsLargeAddressAware() ? 0xBFFF0000 : 0x7FFEFFFF;
_pointerSize = process.Is64BitProcess() ? 8 : 4;
}

Nice, thanks!

Here is my code for selling (it doesn't matter how big item is):

int items_sold = 0;

try
{
	IEnumerable<Enigma.D3.ActorCommonData> acds = Enigma.D3.Helpers.ActorCommonDataHelper.Enumerate();

	foreach (Enigma.D3.ActorCommonData acd in acds)
	{
		if (acd.x114_ItemLocation == ItemLocation.PlayerBackpack)
		{
			if (!CanSellOrSalvage(acd))
				continue;

			int[] pos = new int[] { 535 + acd.x118_ItemSlotX * 28 + AutoIt.Random(-2, 2), 354 + acd.x11C_ItemSlotY * 27 + AutoIt.Random(-2, 2) };

			AutoIt.MouseMove(pos[0], pos[1], 10);
			AutoIt.Sleep(ITEM_HOVER_TIME + AutoIt.Random(0, 150));

			AutoIt.MouseClick("right", pos[0], pos[1]);
			++items_sold;
		}
	}
}
catch (Exception)
{
}

I guess you can determine size based on item type.

How to read blood shards? I can't find this anywhere, only there seems to be DoubleBloodShards attribute which is about the bonus from bounty at some difficulty?

[CrEEzz]

for (int i = 0; i < Enigma.D3.PlayerData.Local.xD36C_VendorTokenCount; ++i)
{
	if (Enigma.D3.PlayerData.Local.xCB6C_VendorTokens[i].x00_GameBalanceId == -1691237125)
		return Enigma.D3.PlayerData.Local.xCB6C_VendorTokens[i].x04_Value;
}

[gottagofast]

Thank you CrEEzz, that is very obscure I would have never figured it out.

Does anyone have code snippet to convert between world and screen coordinates? I can't get it to work properly because the camera has weird angle I don't know how to calculate it.

[azgul]

Sure! This is the code that I currently use. However, I've only been able to get it to work in WindowedFullscreen mode. It works perfectly for 1920x1080 resolution! I'm not sure about others, but I don't see why it wouldn't work for any resolution.

        public static Point FromD3toScreenCoords(Vector3 objectGameLocation)
        {
            Vector3 currentCharGameLoc = Game.Me.Location;

            double xd = objectGameLocation.X - currentCharGameLoc.X;
            double yd = objectGameLocation.Y - currentCharGameLoc.Y;
            double zd = objectGameLocation.Z - currentCharGameLoc.Z;

            double w = -0.515 * xd + -0.514 * yd + -0.686 * zd + 97.985;
            double X = (-1.682 * xd + 1.683 * yd + 0 * zd + 7.045e-3) / w;
            double Y = (-1.54 * xd + -1.539 * yd + 2.307 * zd + 6.161) / w;

            double width = Engine.Current.VideoPreferences.x0C_DisplayMode.x20_Width;
            double height = Engine.Current.VideoPreferences.x0C_DisplayMode.x24_Height;

            double aspectChange = (double)((double)width / (double)height) / (double)(4.0f / 3.0f); // 4:3 = default aspect ratio

            X /= aspectChange;

            float rX = (float)((X + 1) / 2 * width);
            float rY = (float)((1 - Y) / 2 * height);

            return new Point((int)rX, (int)rY);
        }

This works fine for me.
