hello,
I want to get the vector between two objects, so what I do is create pointA and pointB as instances MPoints, and then
vectorA = OpenMaya.MVector(pointA); vectorB = OpenMaya.MVector(pointB)
vectorBetween = vectorB - vectorA
Out of curiosity,I was wondering if you can directly get the vector between two objects without having to do the substraction. Something like vectorBetween = OpenMaya.MVector(pointA, pointB)
Does MVector return only vectors having the origin in (0,0,0)
thx

You don't need to convert both MPoint instances to MVector before subtracting them. As per the documentation page for MPoint (check the `operator-(MPoint)` method), if you subtract two MPoint objects you get a MVector as a result:
vectorBetween = pointB - pointA
vectorBetween = pointB - pointA
Not sure why you'd want to avoid doing a subtraction?

That´s true. douuh!!!

No reason.I thought that maybe I was doing an unnecessary step or there was a more proper way.
Thanks
