There might be a simple solution to this, or maybe not, but I’d like to do something like this:
The link shows a simple setup of a keyframed null pushing a ratchet along one axis.
For the sake of the above GIF, I keyframed both the driver null, as well as the ratchet’s position, but would love to know a simple, relatively fool-proof way of generating the ratchet’s animation through motion inheritance, rather than keyframe.
In this case, I’d want the ratchet to inherit cumulative position values from the driver-null only along the negative z-axis animation, but not the positive.
Can this be done with a regular ol’ Constraint tag (or other tag that is not an Expresso tag?)
If Expresso is the only solution, would anyone be able to suggest a tutorial that covers this problem specifically?
