Basic Multi-Segmented character question

I want to make a multi segmented boss, only simple with 2 sprites connected to each other.

I have a sprite and walking animation for the legs, and then a sprite for the body. On the legs walking animation I have the action point in a different spot for each frame.

How do I make it so the body sprite is always set at the action point of the legs sprite? (therefore giving the effect of the body moving around as the legs animate)

In the event editor I tried doing something with always setting the X and Y co-ordinate of the body to the action point of the legs, but it didnt work.


Thank you for any help.
