MaxScript, Array, save and reload

Blob · Sep 2012

Hello, I have a little question about arrays on which I am quite stuck on.

I have an array.

#("BoxA", "BoxB")

I manage to save this array in an external file, a txt file. My array in here will then look like this :

BoxA,BoxB,

Here now my issue. I want to reload this array back into my script, but for now I only succed to reload 1 of the component of my array !.
I am unable to find back my #("BoxA", "BoxB") from the BoxA,BoxB, saved in the file ! I have try so many diferent tricks that I cant tell them all in here...
Someone could at least point to the good direction ?

Thanks !

maxscript's text handling is a bit weak but there's no reason on earth why you couldn't do this

have another look through the textstream/parsing stuff in the reference - there'll be something you can use

Hi,
this should do the trick. I suggest to make a function out of it.

(
    -- Open the FileStream to read from disc
    local theFileStream = openFile "C:/test.txt"

    -- Initialize an empty Array to store the result
    local asWords = #()

    -- Enter a while loop that terminates once the full file has been read
    while ((eof theFileStream) == false) do
    (
        -- Read one set of characters delimited by a comma...
        local sWord = readDelimitedString theFileStream ","

        -- ...And append it to the result array
        append asWords sWord
    )

    -- Close the FileStream
    close theFileStream

    -- Cleanup memory used by the FileStream
    free theFileStream

    -- Display the resulting Array in the Listener
    format "asWords: %\n" asWords
)

Cheers

Thanks a lot, this is working great.
Looks like I was completly wrong in my way to loop in the file.

Thanks ! : )

Another method would be to save your array to the file like this:

format "%\n" (MyArray as string) to:MyFile

Then load it like this:

MyArray = execute(readline MyFile)

You could also try saving the file as a INI file instead.

Look up INI save load in the documentation. You can make sections as well. I'm currently using INI files for storing a lot of data.

monster : Looks like an even more simple solution for me, So if I understand well my array will be save just as it is as a string, then to load it I wont have anymore to do any loop in the file, just execute it as it is. (I will test all that very soon :] ).

McGreed : those ini files looks very interesting indeed, thanks for the information ! :]

For splitting text strings into Arrays, I usually use the character ¦ as seperator, since it never seem to be used for anything normally, and not something you would use in for example a filename.

a = filterString "bibot¦Tiktika¦string1¦23¦true"
print a[3] -- gives "string1"
