Posted: Tue Aug 13, 2024 11:35 am Post subject: Get Process path

I am trying to use Lua to edit some files from the game directly.
The target file is player.json which stay in the same directory folder with game.exe

Code:

enumModules()[1].PathToFile

I tried this to get the path to game.exe but it kept return to error
when I tried to modify it

Code:

enumModules("game.exe")[1].PathToFile

it return to
C:\Program Files\Cheat Engine 7.5\

Any idea what's wrong? Sad

Here is my code

Code:

-- Get the executable path using enumModules
local exepath = enumModules("Game.exe")[1].PathToFile

-- Extract the directory path from the executable path
local gameDir = exepath:match("(.*[/\\])")
local filePath = gameDir .. "player.json"

print("File path: " .. filePath)

local searchPattern = '"misc/ms/":2'
local replacePattern = '"misc/ms/":4'

-- Function to read the contents of the file
local function readFile(filePath)
local file = io.open(filePath, "r")
if not file then return nil end
local content = file:read("*all")
file:close()
return content
end

-- Function to write content back to the file
local function writeFile(filePath, content)
local file = io.open(filePath, "w")
if not file then return false end
file:write(content)
file:close()
return true
end

-- Read the original content
local content = readFile(filePath)
if content then
-- Replace the specific line
content = content:gsub(searchPattern, replacePattern)

-- Write the modified content back to the file
local success = writeFile(filePath, content)

if success then
print("File updated successfully.")
else
print("Failed to write to the file.")
end
else
print("Failed to read the file.")
end

This will replace all matching directories.

If you want it to be a single directory or a specific order, tell us what it should be.

Code:

function lineReplace(pth,src,rpl)
local filePath = pth
local content1 = ""
local file1 = io.open(filePath, "r")
if not file1 then return nil end
for line in file1:lines() do
if string.find(line, src) then
newline = string.gsub(line, src,rpl)
content1 = content1 .. newline .. "\n"
else
content1 = content1 .. line .. "\n"
end
end
file1:close()
local file2 = io.open(filePath, "w")
file2:write(content1)
file2:close()
end

proc_fileandpath = enumModules()[1].PathToFile
gameDir = extractFilePath(proc_fileandpath)
--print(gameDir)

local searchPattern = '"misc/ms/":2'
local replacePattern = '"misc/ms/":4'
local fileDir = gameDir .. 'player.json'

lineReplace(fileDir,searchPattern,replacePattern)

I'd make minor changes, but overall, it works fine for me. What about it doesn't work for you?

Code:

local exepath = enumModules("Game.exe")[1].PathToFile

local gameDir = extractFilePath(exepath)
local filePath = gameDir .. "player.json"

print('EXE path:', exepath)
print('File path:', filePath)

local searchPattern = '"misc/ms/":2'
local replacePattern = '"misc/ms/":4'

local function readFile(filePath)
local file, err = io.open(filePath, "r")
if not file then
return file, err
end

local content, err2 = file:read'a'
local closed, err3 = file:close()

if not content then
return content, err2
end
if not closed then
print('Warning:', err3)
end

return content
end

local function writeFile(filePath, content)
local file, err = io.open(filePath, "w")
if not file then
return file, err
end

local written, err2 = file:write(content)
local closed, err3 = file:close()

if not written then
return written, err2
end
if not closed then
print('Warning:', err3)
end
return true
end

local content, n_matches = assert(readFile(filePath)):gsub(searchPattern, replacePattern)

if n_matches < 1 then
print'Warning: pattern not found'
else
assert(writeFile(filePath, content))
end
