hey all, I've been writing a command plugin which does come
calculations based on it's input and returns a vector back to the
script which was calling it. It's been a while since I've written a
plugin and I've never written one in python so please excuse the
simplicity of the question but I haven't found my answer in the
documentation so as a last resort I'll post it here.
this is the end of my "doIt" method for my class derived from
OpenMayaMPx.MPxCommand, I am trying to return the vector 'vecDegrees'
back to the python script which is calling this command:
retval = OpenMaya.MScriptUtil()
retval.createFromDouble(vecDegrees[0],vecDegrees[1],vecDegrees[2],0)
retvalFltPtr = retval.asFloat4Ptr()
return retvalFltPtr
from gleaning the documentation I guessed that this was the correct
way to do it, but I am still getting an error from the calling script
which is trying to index the return value, it says 'NoneType' object
is unsubscriptable, so I guess I'm still returning a NoneType
object.
is this the correct way to return a value from a scripted command
plugin ? I tried various methods (such as appendToResult) but got
various errors and the documentation is really not very helpful. Any
help would be much appreciated for this seemingly simple task.
thanks
-Greg
