It is not necessary to make any modifications to the scripts if you load them the standard way via the text window. As I say in the ‘Installation Information Page’:
“It is possible to run Fiber 2.03 from the script window (as opposed to the standard method of running it from a text window) by making a couple of minor modifications to the FiberGui.py file.”
If you are not comfortable editing Python scripts, that is probably the better way to run the script(s).
If that’s not an issue and you wish to make the script easier to use, as is the case with more recently created scripts, or scripts that have been updated to be used in the Script Window, then you can make the modifications. Fiber is a little different in that it relies on more than a single Python script; which makes it a little more challenging setting it up to work with the new system of loading Python scripts.
So if that disclaimer doesn’t dissuade you, then proceed:
You only need to copy that header to the FiberGui.py file (version 2.03).
Then ensure that it and the remainder of the Fiber support scripts are copied into your scripts directory. For WinXP, this is:
C:\Documents and Settings%User_Name%\Application Data\Blender Foundation\Blender.blender\scripts
*Note: The location of your scripts directory will depend on your OS and the installation options you selected when you installed Blender.
This really only saves a small amount of effort of having to manually load the Fiber script files. If you intend to use the ‘Use Wind’ function, you will need to load the FiberAnim.py script via the text window method, since you need to create an Object script link. In that case, using the Script Window method is not too useful, and it is best to load all of the Fiber scripts via the text window.
As soon as Ripsting finishes his 2.5 release all of this will be moot anyway, but only Ripsting knows when that will be
Hope that helps.
