Darren,
I can’t take credit for this; it’s from my co-worker, Drew Loveridge…
— If you don’t give it a list of nodes, it will use the currently selected
nodes as the default list.
— It returns a list, for example: [26, -458] -- which is the center x, y
position of the node list. Then, you can create your new node and use those
values to set the XYPosition for the node, probably with an offset on Y... I
use it all the time!
def nodeList_center(nodeList=None):
'''Node placement function, from Drew Loveridge...'''
if nodeList == None:
nodeList=nuke.selectedNodes()
nNodes = len(nodeList)
x=0
y=0
for n in nodeList:
x += n.xpos()
for n in nodeList:
y += n.ypos()
try:
return [x/nNodes,y/nNodes]
except ZeroDivisionError:
return [0,0]
