Good job nux.
I like how you implemented the other timeline windows.I needed to use a reverse loop in Coffee because if I had for example: keys ten frames apart and an offset value of ten. The first key would get moved on top of the last key. Then when the loop came around a second time. The keys were all on the same frame and it couldn't figure out what to move.
I didn't know of any other way to do it.Deepshade,
Just in case you don't know this. What nux posted is a method.
So if you want to use this in the python script manager. You paste it above the def main section.
Then call to the method like this:def main() : obj = doc.GetActiveObject() offset = 15 #change this value as needed MoveSelectedKeys(obj,offset,timeln = 1) if __name__=='__main__': main()

Let me add, that in the SkriptManager op is automatically the selected Object.
And you don't need to overload the timeln since you don't want timeline 2,3 or 4.
So this works too:import c4d def main() : offset = 15 #change this value as needed MoveSelectedKeys(op,offset) if __name__=='__main__': main()

Hi all
Finally escaped from the last job.
A couple of things
1
Confusion
Just to confirm - the original concept was for staggered keys on multiple objects
Don't get me wrong - not complaining - just need to be clear what I'm seeingThe code is there in the while loop looks like it iterates through all the tracks of a single selected object.
If I select more than one object - nothing happens? (no provision in script so far)2
I'd assume (if you want to modify keys differently for different objects) it would be better to write a small function
and modify the Key value before running Key.SetTime(...etc
dependent on the number of selected tracks
Sadly I cant see a way to return the count of selected tracks (yes Scott I now see the route) - so I guess
the whole things needs to run in an outer loop - iterating through the selected objects?Another issue - if you modify the offset inside the While track loop
ie after
key.SetTime..
with something as simple as offset = offset + 10
Assuming you have a POS ROT SCALE tracks as well
Selecting all tracks is fine
Selecting just one track ie POS - inserts two extra sets of keyframes
as the while loop count is based on the total number of tracks
Cant see a simple solution3
can't find reference to
C4d.NBIT_TL1_SELECT in the SDK - I take it these refer to the 4 timelines
Where did you get that info pls?def MoveSelectedKeys(op,offset,timeln = 1) : # offset in frames import c4d if (not op) or (not offset) : return False if timeln == 1: timeln = c4d.NBIT_TL1_SELECT elif timeln == 2: timeln = c4d.NBIT_TL2_SELECT elif timeln == 3: timeln = c4d.NBIT_TL3_SELECT elif timeln == 4: timeln = c4d.NBIT_TL4_SELECT else: import math timeln = math.fmod(timeln,4) MoveSelectedKeys(op,offset,timeln) doc = op.GetDocument() doc.StartUndo() track = op.GetFirstCTrack() if not track: return False fps = float(doc.GetFps()) while track: curve = track.GetCurve() cnt = curve.GetKeyCount() for i in xrange(cnt) : key = curve.GetKey(i) if key.GetNBit(int(timeln)) == True: tme = key.GetTime() doc.AddUndo(c4d.UNDOTYPE_CHANGE,op) key.SetTime(curve,c4d.BaseTime(offset/fps+tme.Get())) track = track.GetNext() doc.EndUndo() c4d.EventAdd(c4d.MSG_UPDATE) return True import c4d def main() : offset = 50 #change this value as needed MoveSelectedKeys(op,offset) if __name__=='__main__': main()

1:
You can simply use the function in an iteration through the selected objects.What means staggered ? Don't know the word ^^
2:
Why modifieng the
key value ? I thought it's about moving keys ?
And what do you want to achieve with offset = offset + 10Don't select a track, select the keys.
3:
It's in the GetNBits() function. Search for it without the c4d. in front.I'll can answer your questions better later when im at home in about 2 hours.
Till then,cheers

That shouldn't be a problem.

Hey Nux95
This is just great
And there's so much useful stuff here for reference
It's really appreciated - many thanksline 103
op=list[i+1]
is throwing an error
index out of rangeI guess this is just incrementing one object too many? at the end of the selected objects
Not wanting to take anything away from what you've done here - far beyond the call of duty
I think it would be nice to have the 'processing' part of the script possibly
in a functionie release a collection of key manipulating scripts - by just changing the function
stagger - by offset - as we have now
stagger - by total time - total time over which to stagger all frames
stagger exponentially large to small
stagger exponentially small to large
etc etccheers again

Shouldnt. 'op' is already the object with index 0, and 'i' starts with '0', so the next object for 'op' in the first iteration should be 1 => 'i+1'
But .. Hm, very bizarre. I didn't recieve that error, but as I think about it, that error MUST occure at the end of the loop.
Try it like this and tell me if the problen still exists:op = lst[i+1] if not op: break # Hopefully there is a 'break' expression for 'for'-loops. If not try something that stops the loop
stagger - by total time - total time over which to stagger all frames
stagger exponentially large to small
stagger exponentially small to large
etc etcWhy not writing a Plugin ?

Does the Console tell you this ? O.o
If A function calls itself, everything starts again. But you may have changed some values before. (Here the timeln variable)

I think its to do with this function setting op to the first object in doc

that way op is never NULL

Any feedback on programing 'form' would be appreciated.
Think it would be useful to have a couple more transformations
Stagger2 - enter total stagger length - x frames (rather than current overlap in frames)
Accelerate - gradually space out over x frames
Decelerate - reverse above
Stack - thats essentially stagger with no overlap?
