Hello.

First of all i want to say huge thanx to DarkByte for great tool, and samuri25404 for his A Very In Depth Tutorial on Auto Assembler.
Now i understand much more. Hacking with CE is really not difficult, when you understand these things

I am not asking to do everything for me, no, i want to understand how can i do it by myself, and here i need your help.

I have an idea of slow mana replenish in the Nox game.
For now, it is not only idea.
What i know for now:
- 6 and 8 lvls of official tutorial. (7, with code injection is still difficult for me)
- I can find right pointer in CE in tutorial of 4 byte type
- very basic understanding of code injection (but A Very In Depth Tutorial on Auto Assembler made things easier to understand)
- a desire to learn new things.

What do i have:

A slow iteration of the value by 1, every 0.1 seconds. I have already found this code

Code:

require "socket"

function sleep(sec)
socket.select(nil, nil, sec)
end
maxmana = 76
i = 0
repeat
print(i) -- Incrementing value
sleep(0.1)
i = i + 1
until i == maxmana

Reading value of the maxmana from the file, that was previosly written to it by another lua script, that was plugged it into game.
I am doing this these way because every lvlup - character has new value of maximum mana, and i don't want to watch over this value over and over again and change it manually in CE code. I have found my way to transmit current maxmana value to the maxmana.txt file.

So, open file and read value

Code:

function readfile()
local contents = ""
local file = io.open("maxmana.txt", "r" ) -- open for read-only
if (file) then
-- read all contents of file into a string
contents = file:read()
file:close()
else
print("file not found")
end
print(path)
end

What i do not have:

A right pointer, so i can manipulete right value of the mana, using lua script.
The way to get and operate value of the pointer or just first dynamic adress with lua
Under "operate" i mean using my lua script to increase current value of current mana, in the script it is "i" variable.

Description of the problem:
There are 2 adresses that affects on right value of mana (both can change it). And one have 1 byte, and second - 2 bytes type, not 4 like in tutorial.

Watch 1 screenshot below.

Ok, i will try to use breakpoint (F5) and see what accesses this adress.
Please notice, that window was not empty when i opened it. Somehow instruction appears instantly, even before i actual changed mana value in the game.

Watch 2 screenshot below.

Then change the value of mana

Watch 3 screenshot below.

Well now i dont know what to choose.
Because in tutorial there was

Esi+4 or ebx depending on the instruction you chose. Read a pointer tutorial and find the pointer using the value in esi (or ebx). 4 bytes or 2 bytes doesn't make a difference. Or alternatively, learn code injection and write a script to inject the value you desire to the code.

I don't understand the obsession with lua people have these days, they don't understand the basics of gamehacking and concepts such as code injection/pointers or how the memory works to begin with and still, jump into writing lua scripts.
