I am getting a syntax error called -- Syntax error: at ;, expected <factor> In line: -- File name: ) C:\Users\selva\OneDrive\Desktop\code_14.ms -- Line number: 50

Now I am completely new to the max scripting to be frank for scripting itself so i was trying to make a max script that allows me to have this functionalities
Functionality:

• Source Folder Selection: When you click Select source folder, it opens a dialog to choose a folder. This folder is stored in the sourceFolder variable.
• Target Folder Selection: Clicking Select target folder allows you to select a destination folder unless the Same as input checkbox is selected.
• Same as Input Checkbox: If this is checked, the script saves the .fbx file in the same folder as the .max file.
• Conversion Process: When you press the Start conversion button, the script converts all .max files in the source folder (and subfolders) to .fbx. The .fbx files are saved either in the target folder or in the same folder as the .max file, depending on the checkbox.
  
  and the code i wrote with the help of chat gpt ,Gemini and when i ran the code i am always getting the error
  -- Syntax error: at ;, expected <factor>
  In line: -- File name:
  )
  C:\Users\selva\OneDrive\Desktop\code_14.ms
  -- Line number: 50
  
  this is the code i generated using the ai can any one review it and explain what i am doing wrong
  

  -- UI Creation

  createDialog convDialog
  
  thanks

UPDATE
I now actually separated  the code into three parts, each handling the functionality of one button each time now part 1 and part 2 didnt had any errors in it but the part 3 alone had the issues.

Part 1: Folder Selection for Source

This part contains the functionality to select the source folder.

Part 2: Folder Selection for Target and Same as Input Checkbox

This part allows the user to select the target folder and use the "Same as input" option.

Part 3: Conversion Functionality

This part contains the conversion logic from .max to .fbx.


now the code in the PART 3 is

-- Part 3: Start Conversion

try (destroyDialog convertDialog) catch()
rollout convertDialog "Start Conversion" width:300 height:100
(
-- UI Elements
button btnConvert "Start conversion" pos:[10,10] width:280
local sourceFolder = "YourSourceFolderHere" -- Replace this with the selected source folder
local targetFolder = "YourTargetFolderHere" -- Replace this with the selected target folder
local sameAsInput = false -- Replace with the actual state from your UI

-- Conversion Function
on btnConvert pressed do
(
if sourceFolder == "" then
(
messagebox "Please select a source folder!"
return
)

-- Ensure a target folder or "Same as input" is selected
if not sameAsInput and targetFolder == "" then
(
messagebox "Please select a target folder or enable 'Same as input'!"
return
)

-- Gather .max files from the source folder and subfolders
local maxFiles = getFiles (sourceFolder + "\\**\\*.max")

if maxFiles.count == 0 then
(
messagebox "No .max files found in the selected folder!"
return
)

-- Loop through all .max files and convert to .fbx
for maxFile in maxFiles do
(
local folderPath = getFilenamePath maxFile
local fileName = getFilenameFile maxFile
local fbxPath

-- Set output folder
if sameAsInput then
(
fbxPath = folderPath + fileName + ".fbx"
)
else
(
-- Create a subfolder in the target folder that mirrors the source folder structure
local relativePath = folderPath[sourceFolder.count+2] -- relative subfolder path
fbxPath = targetFolder + "\\" + relativePath + "\\" + fileName + ".fbx"
makeDir (getFilenamePath fbxPath) -- Create subfolder if not exists
)

-- Load and export the file
loadMaxFile maxFile useFileUnits:true quiet:true
exportFile fbxPath #noPrompt using:FBXEXP
format "Converted: % to %\n" maxFile fbxPath
)

messagebox "Conversion complete!"
)
)

createDialog convertDialog

i think it will make a bit easier for you guys to solve my problem

No offense but I doubt people here will find the time to help you to debug AI-written code.

Why do you think this code should work?

What you describe what you are trying to get is a batch converter that loads from source and exports to target folder as FBX. There should be already a handful of free (and functional) scripts out there that will do this for you.

Here are the three top hits I found when searching for "3ds Max batch converter"

• https://apps.autodesk.com/3DSMAX/en/Detail/Index?id=8386770510783297463
• https://www.scriptspot.com/3ds-max/scripts/batch-exportimport
• https://www.scriptspot.com/3ds-max/scripts/batch-exporter-0

I have not tested any of them but your time might be better spent evaluating this (or trying to understand their code) rather than wasting time with AI generated code...

good luck

Sometimes, I successfully use ChatGPT to write code. ChatGPT generates good names for functions and variables and writes excellent comments. Of course, I always remove the body of its functions, but everything else can be utilized.👍

Honestly speaking, the keyword is sometimes. I would rather use the words rarely and depends on. 😁
