[Unsolved] How to interact with a pendulum?

Hi, I made this test [link: x.nonvivoin.me/miley/], the sprite has the sine behaviour controlling the angle.

I'm having a hard time trying to find a way to interact with the motion. I'm talking about the user holding the mouse on the sprite, moving it back and then releasing the mouse, causing an acceleration in the motion.

Any clue, please?

Since it is not possible to control the cycleposition, you should manually code the change of angles instead of using the sine behavior.
