Move pivot to object center via python

[cjess]

Hi-

I would like to center the pivot of an object via python script. It would be the equivalent of the "Move to Object Center" buttons in the Transform Window.

I know I can use this command to set the Rotation pivot manually:

setTransformNodeRotatePivot(node, x, y, z, worldSpace)

But I want the pivot at the object's center. So I'm looking for a different command, something like setTransformNodeRotatePivotCenter(node)

or I need to get the x,y,z values of the object's center first and transfer them via variables.

I am not aware of either option.

Thanks for any help!

getBoundingBoxCenter() gives you a vector with the x, y, z coordinates of the object you than use to center your pivot.

Thank you for your quick reply, not sure how I missed that. However, getBoundingBoxCenter() returns a Vec3f.

It does not support indexing so I cannot call a specific x, y or z value.

I was hoping something like this would only call the first value of the Vec3f

print getBoundingBoxCenter("myNode", false)[0]

 but it returns the error 

TypeError: 'Vec3f' object does not support indexing

So I'm not sure how to convert individual values from the Vec3f to floats as required by

setTransformNodeRotatePivot

Any more ideas? Vielen Dank schon mal

bBoxCenter = getBoundingBoxCenter(getSelectedNode(), False)
print str(bBoxCenter.x()) + ',' + str(bBoxCenter.y()) + ',' + str(bBoxCenter.z())

Thank you @seiferp and @marc.winter2 !

The command setTransformNodeRotatePivot requires float values for x,y and z positions so I changed the script just in case anyone else comes across this thread.

I also changed getSelectedNode()  to findNode("myNode")  as I am targeting a specific node every time.

bBoxCenter = getBoundingBoxCenter(findNode("myNode"), False)
setTransformNodeRotatePivot(findNode("myNode"), float(bBoxCenter.x()), float(bBoxCenter.y()), float(bBoxCenter.z()), false)

This was beyond my Python knowledge so thanks again, I learned something!
