Making an effort to understand what I'm seeing

Line 14 function call within itself - seems incorrect?

MoveSelectedKeys(op,offset,timeln)

I am sorry, I may can go to my pc this weekend, but not earlier.

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)

Can anyone tell me why this message
doesn't pop up if NO object is selected using the function from the code above?

lst = GetActiveObjects(doc)
   op = lst[0]
   if not op:
   gui.MessageDialog("No objects selected")
   return False #leave the script if not an object

Dunnoo .. Gonna test this this weekend. Maybe it's because op = lst[0] ist not in the right column ?

  lst = GetActiveObjects(doc)
  op = lst[0] ## here
    if not op:
        gui.MessageDialog("No objects selected") 
        return False #leave the script if not an object

Hi Nux

nope, not that - must be forum paste incorrect
indent is as your example

appreciate you can't test at moment

I think its to do with this function setting op to the first object in doc
if nothing selected
that way op is never NULL

the list only gets appended if op is selected.

And this is where I'm at so far

Ignore some Print items - just for console checks

Still trying to make it modular
ie have a function for each type of key transform - (just stagger in this one)
appreciate any advice on good/bad code form

added gui to take offset
count selected objects - need more than 2
and now first object doesnt get offset (its popped off array)

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?

Well, works fine. If you want potential increament for eg. you need to calculate something with the offset value.
