I have a wire object that roughly holds it's shape, and I have another object that travels along it.
I want the object travelling along it to perturb it slightly as it does so, but I juts cannot seem to find a method to make this happen.
As you can see from the image I've tried attaching a pointforce node that's position is the referencing the box position, but my current setup just makes the curve seem to go crazy, and makes the box fail to follow the curve.

On a more general note, trying to do this just makes me realize that I don't have a clue what I'm doing really, and I'm having a hard time finding resources that actually teach you how to build these DOP netoworks to achieve specific results.
It seems to be that, unless there is a tutorial showing exactly the effect that I'm after, I'm completely at a loss as to what to do. If anyone has any resources/tutorials that are good for learning really how DOPs work (not just “let's use the shelf tools” videos) please let me know.
