How to Hook Field Offsets in Lua Script

[rand1337]

Hi, Is it possible to hook field offsets using lua? If its possible, can u send a template? Thanks.

Do you mean get the offset from the encrypted script?

No, il2cpp fields from dump

u mean, give the offset (taken from lib) to script & it will mod the offset?

no, field offsets in dump.cs.

From User @NoFear in another post

"You would use a disassembler... IDA for example. Then could search strings for the "0xD0".  Granted, will be insane number of results. Because the 0xD0 I believe could be used for something else on another function. "

Field offsets don't go to a specific address or function, and they should be used to locate something else.

Edit: IDA does have a freeware version but I don't think it supports arm64 you may have to use ghidra

local function memoryPatch(offset, value)
  local so = gg.getRangesList('libil2cpp.so')[1].start
  local v = {}
  local v[1] = {}
  v[1].address = so + offset
  v[1].flags = gg.TYPE_QWORD
  v[1].value = value .. "r"
  gg.setValue(v)
  gg.toast('memory patched')
end

memoryPatch(0x4856E5, HEX VALUE)

field offsets can be hooked using update function in lgl mod menu, but i ask how to do it in game guardian lua script? its possible?

so theres no way to mod 'field'??

 

 

 

i saw some interesting field hacks... but since they are like 0x98 or similar, i was thinking myb these cant patched

He is talking about instance variables from a dump.cs class 

Example: 

//Example Simulation
//Every field has an offset beside it, these are example offsets
public class Enemy {
  //Fields
  public float health; //0x12
  public boolean isDead; //0x23
  public double loot_drop_chance; //0x29
  public boolean isBoss; //0x10
  public float dmg; //0x11
  
//Next would be methods and other stuff but the starting variables are what he wants to be modded
}

You cannot Hook instance variables from a dumped lib file with lua. you may only use C++ using a function pointer

Thank you, that's the answer I was looking for.

You are welcome, also Yes! you could learn C++ and Java so you could learn modding with lgl (template isn't for newbies) 

Learn java. then C++ then you should sign up on the polar mods forums after you are done with both. just learn the basics

then you could learn the hooking, hex patching API Library they have

Have a nice Day!

Search pointer for class and use fields to jump to offset
