[C#][Copy/Pasta] Out of process DBC reading

[Cypher]

And don't forget teh proxiez!

And running them in ring0.

[SinnerG]

for (uint tableBase = CLIENT_DB_REGISTER_BASE; Process.Reader.ReadByte(tableBase) != 0xC3;
tableBase += 0x11)
{
var index = Process.Reader.ReadUInt32(tableBase + 1);
var tablePtr = Process.Reader.ReadUInt32(tableBase + 0xB) + 0x18; // 0x18
Tables.Add((ClientDb)index, new DbTable(process, tablePtr));
}

Are the offsets defined in here still valid (I updated CLIENT_DB_REGISTER_BASE to 0x005C8E80)

I get what seems to be a correct number of 'tables' but for example the DB_Map 'table' has 1million+ rows according to the struct ;p

Any ideas?

Thanks, I'll start fooling around with it even though I'm pretty sure I'll end up pulling my hair (or whining at you!)

[leather]

nice work.
I want to know is there any information about the StringTable in the struct 'WoWClientDb'.For example the Item.DBC,how can i find the itemname by the itemid from StringTable.

[SinnerG]

Is this working for anyone then? (Got modified offsets?)

I think that I'm just going to make a DBC reader :P

[Apoc]

Updated the code. It now works for packed DBCs. (Spell.dbc, and a few others)

Keep in mind; if you use GetLocalizedRow, then you can't use Row.GetField. I'm too lazy to add the extra memory handlers to switch between reading from your local address space, to WoW's.

Feel free to add it though.

[miceiken]

Is the offset WOW_USE_SPELL_UNPACK in the Info Dump Thread? I have searched for both 'spell' and 'unpack' but with no success.

Check the ClientDb__GetLocalizedRow func. It's the first 'call' to another func.

One simply does a memcpy, the other does the unpacking.

@Apoc or others-

Have you been able to successfully read Spell = 0x00000194, // 0x00A751FC
out of this? I've been struggling (struct size is 0x69 for me)

The Spell.dbc struct has changed.

The cut out 24 bytes of data somewhere in it.

[miceiken]

Does anyone care to share the updated Spell.dbc struct?
Neither Spell.dbc - Source Peek Wiki nor Spell.dbc - WoW.Dev Wiki is updated.

I haven't extensively checked where they removed the 24 bytes. So I just cut 24 bytes out of the giant effects entries. The rest seems to work fine. (At least, the stuff we use does.)

I don't have the time to re-reverse the struct and figure it out.

No (or few use) for now : Once MaNGOS (or any other wow emu out there) is updated to 3.3.3, check their source code

I created my own DBC reader 'semi-compatible' with the MaNGOS 'format':

It reads the DBC files itself though (not from memory)

For spell.dbc for 3.3.2 it was (the format):

public const string Spell =            "@iiiiiiiiiixixixiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiifxiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiffffffiiiiiiiiiiiiiiiiiiiiifffiiiiiiiiiiiiiiifffiiiiiiiiiiiiixssssssssssssssssxssssssssssssssssxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxiiiiiiiiiiixfffxxxiiiiixxxxxxx";

Where @ is the spell id, i an integer, x is ignored, f a float, s a string

[Apoc]

I'm well aware of the 'old' format.

It's the new one that we need

For instance: here's the 'current' one we use in Onyx. (With the 24 bytes of 'extra' data commented out)

It's not 'perfect' or complete, but it gives us all the info we need.

were removed in 3.3.3 patch, but you commented out

        //[MarshalAs(UnmanagedType.ByValArray, SizeConst = MAX_EFFECT_INDEX, ArraySubType = UnmanagedType.I4)]
        //public int[] EffectMiscValue;
        //[MarshalAs(UnmanagedType.ByValArray, SizeConst = MAX_EFFECT_INDEX, ArraySubType = UnmanagedType.I4)]

for some reason...
