btHingeConstraint question

[YurG]

Hi All,

I'm newbee in bullet.
I have a problem with a simple "rope" implementation in my project using btHingeConstraint.
Target I want to achieve - entity moves along hing's "arm" and collide with other objects in general way (see picture).
I want to find a way to avoid runtime constraint reinit and object replaing that may cause incorrectness.

All suggestions are welcome.
