Position parse script

iwkya 61 posts12 Feb 2010hi guys,
Does anyone know a little maxscript to help me out. I have an export from a game engine that exports the terrain straight into max which is great, but then all other models export in the centre of the scene. The author of the exporter tells me I need script to be wrote to parse the model location files and relocate all of the models.
The file it exports starts with :-
ModelFile;PositionX;PositionY;PositionZ;RotationX;RotationY;RotationZ;ScaleFactor
.....and then carries on with the list of models like this :-
canopylesstree01.obj;18109.13;99.02845;25778.55;0;332.1488;0;1
I know no maxscript at all, does anyone have a clue where I would start. I would be more than willing to learn this myself but i wouldnt know where to start.
cheers guys -
13 Feb 2010can you please explain it more im not sure if i understand what you want to export where from where?

iwkya 61 posts13 Feb 2010Hi thanks for replying..
Ok, I have a friend coder who has written an export program for a game. Most of it works apart from the location of certains doodads (trees, barrels etc), they are exported great but the location data isn't carried on to the obj file. Instead the exporter creates a text file listing all of the obj's and their positions.
So basically I need a script that will read all of these postion coards from the text file, into 3ds max.
Think you can help, ? -
13 Feb 2010So you just need to read the text file, parse the coordinates and apply them to the objs?
How is the text file laid out? Is it comma separated? If you can post a line from it that would help. -
13 Feb 2010Nevermind, it's right up there....haha. I'll whip up some maxscript for you later this afternoon if no one beats me to it.
-
iwkya 61 posts13 Feb 2010wow really ?? Thank you so much man. If anything i'll be certainly looking at your script to learn as well as use.
btw, would i run the script once i had loaded all of the obj's in the scene ? -

- Code: Select All Code
function readFile = (
-- Browse For File
dataFile = getOpenFileName caption:"Select File"
-- Check
if(dataFile == undefined) then return "No File Selected"
-- Open File In "read" Mode
fileId = openFile dataFile mode:"r"
-- If It Opened, Load Data
dataArray = #()
if (fileId != undefined) then (
while (not eof fileId) do (
myLine = readLine fileId
append dataArray myLine
)
)
-- Close File
close fileId
-- Loop Through The Data Array
for a = 1 to dataArray.count do (
-- Filter String This Line
row = filterString dataArray[a] ";"
-- Row Example
-- canopylesstree01.obj;18109.13;99.02845;25778.55;0;332.1488;0;1
objName = row[1]
floatValue1 = row[2] as float
floatValue2 = row[3] as float
floatValue3 = row[4] as float
floatValue4 = row[5] as float
floatValue5 = row[6] as float
floatValue6 = row[7] as float
floatValue7 = row[8] as float
print dataArray[a]
)
)
That function will browse for a file, read it, and break it up into separate bits of data for you. Without having your assets and knowing exactly what those numbers mean I really can't do much else. I'll be happy to help you figure it out though. -
iwkya 61 posts14 Feb 2010Hi man,
First off thanks for the help, seriously i posted on loads of "big" forums and no help at all.
Ok, the code you wrote i have stuck in a ms file for now, not really sure what to do with it at this stage, but im sure it will be np for you to sort
.
The file the exporter exports is called placementinformation.csv and the text inside goes like this- Code: Select All Code
ModelFile;PositionX;PositionY;PositionZ;RotationX;RotationY;RotationZ;ScaleFactor
canopylesstree01.obj;18109.13;99.02845;25778.55;0;332.1488;0;1

humantentmedium.obj;18304.91;224.7274;25664;0.5;-44.5;8;1
....and continues.
At the minute i am using a batch obj importer to get all of the obj's into max, but as i say they are all in the centre of the scene
If you need anymore info then please let me know, I have uploaded a folder with all the stuff in for you to try your script and test. It would be great if the script worked for other obj's that i plan to export too..

thanks again man, i really appreciate this..

PS, can an admin please stick this in the max script sub forum, sorry i didnt see the sub -
16 Feb 2010ok this is interesting i want to take a look at it but today im very busy... hopefully i can take a look tomorrow.

16 Feb 2010Ok, the function below should work assuming the actual objects in the scene are named the same as the file they were exported to. (i.e. "Box01.obj" contains the object "Box01")
I'm not sure how to have maxScript return the name of the imported object(s), as importFile simply returns true or false depending on if it worked.
To run the script, change the paths below to point to your data, and then run it.
objPath = "C:/Path_To_The_Exported_Objs/"
dataFile = "C:/Path_To_Data_File/placementsInformation.csv"
importAndPositionObjs objpath dataFile- Code: Select All Code
function importAndPositionObjs objPath dataFile = (
-- Check
if(objPath == undefined) then return "No Obj File Given."
if(dataFile == undefined) then return "No Data File Given."
-- Open File In "read" Mode
fileId = openFile dataFile mode:"r"
-- If It Opened, Load Data
dataArray = #()
if (fileId != undefined) then (
while (not eof fileId) do (
myLine = readLine fileId
append dataArray myLine
)
)
-- Close File
close fileId
-- Loop Through The Data Array
for a = 1 to dataArray.count do (
-- Filter This Line By Semi-Colon
row = filterString dataArray[a] ";"
--Extract Data From Line
obj = row[1]
posX = row[2] as float
posY = row[3] as float
posZ = row[4] as float
rotX = row[5] as float
rotY = row[6] as float
rotZ = row[7] as float
scaleFac = row[8] as float
-- Filter Object Name
nameRow = filterString obj "."
objName = nameRow[1]
-- Import Obj
importFile (objPath+"/"+obj) #noPrompt
-- ************************************************
-- NOTE: This assumes the OBJ filename is
-- the same as the actual Object Name.
-- ************************************************
-- Get Obj Name
myObj = getNodeByName objName
-- Position Obj
myObj.pos = [posX, posY, posZ]
-- Rotate Obj
objRots = eulerAngles rotX rotY rotZ
rotate myObj objRots
-- Scale Obj
scale myObj [scaleFac,scaleFac,scaleFac]
)
)

16 Feb 2010I also didn't include a file test (check if the files exist, error out if they don't) because I'm not sure how to do it maxScript, perhaps somebody can chime in with how to do that.

iwkya 61 posts17 Feb 2010cheers man really appreciate this..
Ok, tried it and i get no errors after i put paths in, but nothing happens.
