Maxscript - find name and position in a txt.file

Primergy

Hey,

after I spend the day of unsuccessful tries I hope some here does have an idea.

For a mod-project I need a script which exports all selected objects of a scene to a txt.file (with name, pos, rotation)
Each object has it's own line and the file looks like this:

[Tower, x, y, z, rotation]
[Tower, x y, z, rotation]
[Gate, x, y, z, rotation]
etc

This part works, the problem is the next task.

At the end of the file I need new entries, where I have to list in which lines of the txt. file the object appears, like:

[Tower, Line 0, Line 1, Line x],
[Gate, Line 2],

My current approach is to save the names of the objects into an array and loop through the file, looking for the names and then printing the line.

name_array = #() 
        for o in selection do
        ( 
            prop_name = o.name 
            appendifunique name_array prop_name
        )
         
    --open File again to read it
    in_file = openFile out_name mode:"r+"    
     for i in name_array do
      (
        ?????
       ) 
        
    close in_file

I have looked at the filestream reference of the help file, but I don't have the feeling that the commands do what I'm looking for

The method you are considering would be really slow and difficult. I think the best method is to print both lists at the same time and then combine them. See below.

(
	--CREATE A DATA STRUCT
	struct gameObject
	(
		name = "",
		positions = #(),
		rotations = #()
	)
	
	--SAVE THE CURRENT SELECTION
	selObjects = getCurrentSelection()
	gameObjects = #()	
	
	--LOOP THROUGH SELECTION
	for obj in selObjects do
	(
		isNewName = true
		
		--CHECK IF GAMEOBJECT NAME HAS BEEN ADDED ALREADY
		for g = 1 to gameObjects.count while isNewName do
		(
			if obj.name == gameObjects[g].name do
			(
				--NAME EXISTS, ADD DATA
				append gameObjects[g].positions obj.pos
				append gameObjects[g].rotations obj.rotation
				isNewName = false
			)
		)
		
		--NAME DIDN'T EXIST YET, CREATE A NEW GAMEOBJECT
		if isNewName do
		(
			append gameObjects (gameObject name:obj.name positions:#(obj.pos) rotations:#(obj.rotation))
		)
	)
	
	--CREATE A STRING STREAM
	firstStream = "" as stringStream
	secondStream = "" as stringStream
	lineCounter = 1
	
	--FORMAT TO THE STREAMS CONCURRENTLY
	for obj in gameObjects do
	(
		format "[%" obj.name to:secondStream
		
		for i = 1 to obj.positions.count do
		(
			format "[%, %, %, %, %]\n" obj.name obj.positions[i].x obj.positions[i].y obj.positions[i].z obj.rotations[i] to:firstStream
			format ", Line %" lineCounter to:secondStream
			lineCounter += 1
		)
		
		format "]\n" to:secondStream
		
	)
	
	--CREATE FILE FROM STREAMS
	--FOR DEBUG PURPOSE I'M JUST PRINTING TO A SCRIPT WINDOW
	in_file = newScript()
	format "%" (firstStream as string) to:in_file
	format "%" (secondStream as string) to:in_file
)

Thank you, your solution is indeed better then mine^^ - thats the problem if you only have knowledge of some commands and want to do something more complex
