Hi
Ok I have the first bit thanks to Nathan's tips and is below. If you create
transform node and animate the translate x parameter - select some keyframes
(can have gaps), move further down and run the code (make sure node is
selected)
then it pastes the keys from current position on. So far so good if not a bit
hacky no doubt.
Now this will run in the animation menu which returns all selected curves via
nuke.animations so I'm hoping to use this to auto fill in curve details.
However
I'm unclear how to do this so thought I'd see if any one can help. With the
following when run in animation menu I get things like this.x as well as
transform1.translate.x - depending on which way the wind blows (ok haven't got
my head around the logic yet)
def pasteAtPosition():
a = nuke.animations() #picks up selected animation curves
print a
What I want is to use the above and integrate in below. All help much
appreciated
Code below (run in script editor) - and yes its WIP!
#test for picking up first value for offset and setting keys
n=nuke.selectedNode()
na=n['translate'].animation(0)
ns=na.size()
print ns
i=0
offsetStart=0
while i < ns:
keySelected= (na.keys()[i].selected)
if keySelected:
keyVals= (na.keys()[i].x, na.keys()[i].y)
offsetStart+=1
if offsetStart==1:
offset=nuke.frame()-keyVals[0]
print ('keySelected: '+str(keySelected)+' keyvalues: '+str(keyVals)+'
offsetStart: '+str(offsetStart)+ ' offset: '+str(offset))
na.setKey(keyVals[0]+offset,keyVals[1])
else:
print ('key not selected')
i+=1

Looking at the code - it looks like I can do this without even having to copy
in
the first place - just select and paste - at least I hope so.

Great shameless plug!
Thanks Nathan - I think i can see what I need at a quick glance. - very useful
Howard
p.s. (have you already done this??)

Why not just use Nuke‘s Python interfaces for dealing with animation curves
and
keys?

I should add its the search for x and replace - move to next one I'm not
sure about - the rest I can figure out
Cheers

Subject: [Nuke-python] copy paste keyframes
Dear all
I want to extend the copy paste keyframes function in Nuke to allow you to
paste copied keyframes to current frame
ie I copy a keyframe at frame 12 and want to paste at 30. At the moment the
only way I know to do this in Nuke is to move the keyframes to desired
position, copy, undo then paste.
A bit clunky.
Someone may have done this and like to share but otherwise...
So in python what is the best way to take the clipboard as such
{:selected_only: x1 0 x10 20} {:selected_only: x1 0 x10 30}
work out the frame difference (current frame - first frame in text)
search for all x'n' s and replace with new value
ie to paste at frame 30
30-1 = 29
find x1 - get number (strip x) add 29
replace x1 with x30
move onto next x add 29
replace
etc...
Any help greatly appreciated
