[Help] Dont know why its not working!

Look at the VMT methods. They're a huge help. You can find the offset to the GetObjectName() method inside the LUA functions. Just go look in IDA and you'll see something like "call eax", this is nearly always a VMT function(it reads basePtr and adds something to it, then calls eax).

EDIT: Sadly, I just looked at the UnitName() lua function, and it doesn't seem to use the vmt BUT it does have the function to retrieve object names(you just have to follow the correct series of jumps to find it). I'm sure it shows unit names and player names, but I'm a little lazy.

Well it doesn't call into the player's GetObjectName VM directly, but they both call the same function.

CGPlayer_C::GetObjectName
----------------------------
push 1
push 0
call GetUnitName (0x5AD970)
retn

and UnitName (the lua function) first makes a shitload of compares to verify that the lua function was called properly and then looks what type the object is, and eventually, if it's also a Unit/Player, calls the same function GetUnitName, that looks again if it's a player or a unit and for a unit just gets the name via [[..+0x968]+0x54], and if it's a player it calls into 0x681970, and that function calls into the one I mentioned earlier.

If you want to find it the next patch, you can just as well take a look at the lua function UnitName, with that function you can update (nearly?) all your 'getName' methods.

Thanks, Ill start to slowllllyyyyyy, XD , follow each jump. In fact I find it very entretaining ^^..... RCE > SUDOKUS

The above is exactly the method I used, way back when, to reverse player names out. It's pretty straight forward. We all know that [obj+0x14] is OBJECT_TYPE, so whenever you see something do something like:

mov eax, [ecx+0x14]
cmp eax, 5
jnz xxxxxxx
cmp eax, 4
jnz xxxxxxx

...you know it's probably going different places based on different object types. One of those little tricks, just like the one lanman mentioned about the VMT.

It's unfortunate that the function does not do the comparison as clearly as you posted. The compiler optimizes out simple cmp's like that into shr's and tests.
