Understanding localized strings (how to read them OOP)

[Tanaris4]

@Main

Well how do I access this OOP? B/c it seems like what you're referring to would only matter if I'm doing injection. Since I'd have to check the stack pointer to determine where the structure actually is.

All I can do now is jump to the spell struct row as follows:

	UInt32 spellDbc = 0xD2E300;
	int spellID = 15616;
	UInt32 minIndex = [memory readInt:spellDbc + 0x10 withSize:sizeof(UInt32)];
	UInt32 maxIndex = [memory readInt:spellDbc + 0xC withSize:sizeof(UInt32)];
	
	if ( spellID >= minIndex && spellID <= maxIndex ){
		
		UInt32 spellRow = [memory readInt:spellDbc + 0x20 withSize:sizeof(UInt32)] + ( 4 * (spellID - minIndex) );
		UInt32 spellStruct = [memory readInt:spellRow withSize:sizeof(UInt32)];
		NSLog(@"Spell Row: 0x%X  Spell struct: 0x%X", spellRow, spellStruct);
		
		// we don't have a pointer to a struct /cry
		if ( spellStruct == 0 ){
			return;
		}
		
		// now I have a pointer to the spell struct, how do I now get to the name/description etc..?
	}

But then I get there, and I don't know how to actually access to the name/description. I will always land on the correct spell ID (which is part of the struct here):
Spell.dbc - wiki.nibbits.com

so I know I'm landing on the struct, but I don't understand where I need to start "unpacking" data - or even how to do this?

Edit: And don't worry, I WILL clean it up once I actually have working code So you won't see +0xC and +0x10 everywhere

You do that by replicating WoW. Do it like WoW does it.

See my thread about OOP DBC reading. I included the unpacking func they use, and also documented what should be passed to it.

(Hint: Check the GetLocalizedRow func in DbTable)

Yep, thanks Apoc, re-wrote your Unpacking function:

		Byte byteBuffer[0x5000];
		
		byteBuffer[0] = [memory readInt:spellStruct withSize:sizeof(Byte)];
		int currentAddress = 1;
		int i = 0;
		int size = 0x2C0;
		
		for ( i = spellStruct + 1; currentAddress < size; ++i ){
			
			byteBuffer[currentAddress++] = [memory readInt:i withSize:sizeof(Byte)];
			
			Byte atI = [memory readInt:i withSize:sizeof(Byte)];
			Byte prevI = [memory readInt:i - 1 withSize:sizeof(Byte)];
			
			if ( atI == prevI ){
				
				int j;
				for ( j = [memory readInt:i + 1 withSize:sizeof(Byte)]; j != 0; byteBuffer[currentAddress++] = [memory readInt:i withSize:sizeof(Byte)] ){
					j--;
				}
				i += 2;
				if ( currentAddress < size ){
					byteBuffer[currentAddress++] = [memory readInt:i withSize:sizeof(Byte)];
				}
			}
		}

Now to verify it's always working for me Looks like the name is at 0x88, which seems a bit strange. Thanks!
