Aw well, I'm not sure what I want to do yet anyway. If I wanted I can just reference the parameters being affected directly from the objects in my scene, I think. need to play with it more
Thanks!

Hi,

I'm afraid it's not possible, op is just a link to the actual object within the scene.
And there is no way to find the corresponding Cmotion Object, and even if you get the Cmotion Object, CMotion[c4d.ID_CA_WCYCLE_TAG_OBJECTS] is currently not exposed in python and you can't iterate the tree.

Cheers,
Maxime.

Hi Maxime,
Thanks, this is great!
I was wondering, is there a way to get other objects in the list, for example if op is the object affected by the action, is there a way to relatively (or absolutely) reference another object in the CMotion object manager?
e.g. I tried op.GetNext() but it doesn't seem to work

Thanks again!
Nick

Hi Nnenov,

Regarding your question, you have to define a function called Action.
Then there is some globals variable available.
doc: BaseDocument - The document of the current Cmotion Object.
op: BaseList2D - The object affected by this python Cmotion action.
time: float - The time in the current document.
cycle: float - Count of cycle already occurs (for example if the Cmotion Time is set to 30F, it's basically int(CurrentFrame)/int(30))
pos: float - Current time position in the cycle (from 0.0 to 1.0)
phase: float - Current value of the phase.
weight: float - The weight of the python Cmotion action.

Here a basic example about how to move an object in the X direction.

import c4d
  
def Action() :
    maxXValue = 100 * weight
    op.SetRelPos(c4d.Vector(maxXValue,0 ,0) * pos)

If you have any question please let me know!
Cheers,
Maxime.
