object spring on a pivot by grabbing and letting go by a mouse

[roach_779]

Hi,

I just been using playmaker for 2 weeks.

I want to grab an object with mouse, drag it, let go, and have it spring back and forth on a pivot until it looses energy. What actions do I use?

grab an object
drag an object
object bounce/spring? physic
lock down on a pivot

This is all done in 2D...orthographic camera.

Thanks
roach
