Help Obi Rope path tracking

[RuralSculpture]

I want to follow the path of the rope and move the characters, how can I do that?
Can we detect rope positions step by step?

Hi,

Not entirely sure what you mean by "detect rope positions step by step", but I guess you mean getting particle positions in the rope? If so, you can do so by iterating trough the rope elements, getting the positions of particles using the particle API:

Hi,

Thanks for the reply,

I want the character to move like the black line attached to the rope taking the positions I'm working on Obi's the sample scene right now.

Then it may be simpler to get  an orthonormal frame from the rope, which you can do by calling ObiPathSmoother's GetSectionAt(float mu) method. Given a normalized coordinate in the (0,1) range, it will return an orthonormal frame in the rope (containing position, normal, tangent, binormal).

Code:

var frame = rope.GetComponent<ObiPathSmoother>().GetSectionAt(0.5); // get frame at the middle of the rope.
