[Closed] Read RGB light colors from file

Dec 18, 2009 7:28 pm

      I'm doing a plugin for FumeFX which involves lights.
      
      I want that the color of the light created is taken from a file.
      
      I'm thinking on something like this:
      
      the file light_color.txt has this:

Light color:

(color 255 0 0)

      and the script has a part like this:

omnilight rgb:(color 230 255 255)

      I want this:

omnilight rgb:[b]LIGHT_COLOR FILE COLOR[/b]

   I want the RGB to read the 3rd line of the txt file.
   
     Thanks
     Nahuel

Search the help file for “FileStream”.

A FileStream class implements text file input and output in MAXScript. A FileStream value represents an open text file in MAXScript. Text file I/O is performed by calling functions on the FileStream value.

So, I managed to get this working:

Here is the code:

(
f = openfile “C:\Program Files\Autodesk\3ds Max 2010\Scripts\Startup\light_color.txt”

    while (not eof f) do
    (
inputData = readLine f
inputData = trimright inputData
inputArray = filterString inputData " "
        
            if inputArray.count == 3 do 
            (
Rvalue = inputArray[1] as float
Gvalue = inputArray[2] as float
Bvalue = inputArray[3] as float
            )

    )
    
    omnilight rgb:(color Rvalue Gvalue Bvalue)
    
)

Text file (light_color.txt):

255 0 0

But when i put that in my plugin, it gives me error.

Here is the plugin:

plugin light myLight
name:“myLight”
category: “myLight”

(
    tool create

(
f = openfile "C:\Program Files\Autodesk\3ds Max 2010\Scripts\Startup\light_color.txt"

    
    while (not eof f) do
    (
inputData = readLine f
inputData = trimright inputData
inputArray = filterString inputData " "
        
            if inputArray.count == 3 do 
            (
Rvalue = inputArray[1] as float
Gvalue = inputArray[2] as float
Bvalue = inputArray[3] as float
            )

    )
    
    omnilight rgb:(color Rvalue Gvalue Bvalue)
    
)
    
    
)

Why?
