Arena Score memory reads

[xulture]

Hi guys,

I've been trying to scan for arena 'game over' score data.

Eg, first person on the list
MMR (before the game started) is Ptr: wow.exe+0xA7CDA8, offset 0x2C. Offset 0x30 is the (signed) MMR change after the game finishes.

(second on the list is 0xA7CDAC, same offsets, third -- add 4 again..)

These locations (and pointers) persist and maintain their values after you exit the game, and get overwritten when the next game that you play finishes.

But I can't find the name of the first/second... person on the list.

Does anyone have any hints?

i'm not into wow but maybe there is just a reference using the id instead of the name?

I'm not sure where you started, but looking at lua commands will give you a jump. I'm sure there's a 'GetArenaScore' API or something similar.

Arenas function pretty much like battlegrounds, so GetBattlefieldScore and GetNumBattlefieldScores should do the trick.

You would know this if you bothered to search the wowapi pages.

I'm not looking for WoW API Function. I'm looking for a location to read this value without running anything inside add-on space. (or via /run ... macro)

(even if I read this with an addon, i get into a messy situation of scanning for lua values, and they need more convoluted memory scans to get to)

/run local pn=GetUnitName("player");local c=GetNumBattlefieldScores();for j=1,c do local n,_,_,_,_,_,_,_,_,_,_,_,_,mp,mc=GetBattlefieldScore(j);if n==pn then print("MMR:"..(mp+mc));end end

So running this when the score is up works as expected, but that's NOT what I'm asking for, read the OP

Hey *******, it's called reverse engineering. No one will give you everything. You have to find some things on your own.

Open IDA, find GetBattlefieldScore function, reverse it and you will get info you want (player names). What's why that function was mentioned here.

I was going along that track, but getting into IDA is a whole new can of worms for me. Was hoping to get away with cheat engine only.

If IDA was the way to go, can someone at least give me a hint how to rebase IDA's file addresses to the stuff I see in memory?

According to IDA, it appears that GetBattlefieldScore implementation starts at 008AA570. (if it is to judge by the "Usage:" text)

How do i find where this ends up in memory?

[streppel]

wowbase+what ida gave you,not?

[xulture]

ida's memory was c00 bytes off, not sure why, but I took your suggestion streppel, and sure enough GUID was staring me in the face

wow.exe+0xA7CDA8 -- guid of first reported character. i was adding offset to get to mmr and change. thanks!!!!
