Help how to use obi handle

[josemendez]

I want you to tell me how to use obi handle. I tried, but it did not work well. 

I did  edit particle> choose particle by selection brush > make obi handle. However the obi handle did not move by transform and movement of rigidbody. What was wrong?

Handles are simply transforms. If you want them to move together with a rigid body, you need to parent them under that rigidbody's transform. However they do not provide two-way coupling with rigid bodies, as explained here:

Quote from the Pin Constraints section:

Particles will be affected by the rigidbody's movements, and the rigidbody will in turn be affected by the particles. This cannot be achieved by fixing particles or using handles, as the rigidbody would completely ignore the particles.

If you want the rigidbody to react to the particles it is attached to, you need to use pin constraints instead of handles.
