[Development] CharObject Struct Of Client (Source)

[-=DarkSim=-]

Hello all)

Today i release emulation of ObjectStruct for client (it like OBJECTSTRUCT of GS, but for main.exe), with it very simply "decompile" some main moments and create hard customs.

And again some moments with "Unknown" names and gaps, but it work)

Geting structure adress from OllyDbg

- (Inter commands)

- (Go to result)

- (Down list)

8128AC4 -> Structure adress

How call to structure from DLL

Spoiler

ObjectCharacter * pPlayer = &*(ObjectCharacter*)*(DWORD*)0x8128AC4;

How add structure to IDA (HexRoys)

Spoiler

1. Shift + F1
2. Press Insert
3. Paste all code from thread head
4. Go to any function with structure adress

5. Set to he type ObjectCharacter*

6. View in result

Examples:
(

To view the content, you need to sign in or register

,

)

P.S.:
- Same need set it type to +4 from main structure (0x8128AC8)
- Same u can add type to ItemObject vars:

Credits: Me (DarkSim)

Version: Season 6 Episode 3 GMO (maybe 1.04d+)
On other versions need make research and check all struct positions.

Bad english and etc

Good luck to all with it)

- u understand where signed and where unsigned value in manual search of movs in this value?

I Don't really care about it, it automatic fill. I care 1 bye, 2 bye, 4 byte or custom struct.

laudaicat
- automatic?...

darksim : one of the popoler main is 1.03K JPN (mabe "the popluer" main ever).
can you make full Object Struct for this main ?

thanks

- Maybe, if have time.

if you can add makecharset decompile source that fit to 1.03K JPN .
thanks mate

 

[podreca]

Good job.
I wonder if you could post the struct of the MuHelper (or MuBot). I would like to add new features to it.

vot tebe ne lenj xD

[mirraseq]

Here is my IDA database of 1.03.25 JPN season 5 main with partially decoded ObjectStruct. There are some interesting values like object scale, rotation, current animation, skill effect counters, etc. Hoever this db is not perfect, it's little messy.

To view the content, you need to sign in or register

- recheck db

Thanks, OBJ_STRUCT have wrong form, in true model information have own struct, like:

	float Unknown28;
	float Unknown32;
	float Unknown36;
	float Unknown40;
	float Unknown44;

its auto-maked structs in ur db?

DarkSim how to generate a struct Object Character?

My Main 1.02.40 (1.02N+ CHS)

 

[-=DarkSim=-]

VeltonD
- I make it manually, with olly & ida
