Initialize om.MDoubleArray(python_list)

Having trouble creating a float or double array in openMaya, with a list of numbers. Is there a trick to getting [.2, 25, 4, 99, -.1] into an MDoubleArray?

MDoubleArray (const double src[], unsigned int count)

How do you create the first arg correctly in python?

Thanks!

MScriptUtil is what you want.

doubles = [.2, 25, 4, 99, -.1]
count = len(doubles)

util = om.MScriptUtil()
util.createFromList(doubles, count)
doublePtr = util.asDoublePtr()

doubleArray = om.MDoubleArray(doublePtr, count)

Oh man, still trying to wrap my head around that thing…

Thanks!

The python equivalent of hemorrhoids.

ya wish API 2.0 was full featured so we can drop MScriptUtil, but it seems it seems API 2.0 is not being worked on anymore, and is not full featured enoguh to be usefull at all
