Turning an object during a drag and drop

I'd make a video. Not sure how many people are comfortable accessing a macro-enabled PPT file to look at what you want.

There are a few ways you can do that. The core of it is to:

• Create a normal bottle state and a pouring bottle state
• Create a normal bread state and a covered bread state
• Then add triggers to change those states.

Here's a video where I tested a few ideas to get you moving in the right direction.

Without seeing the actual file, it's hard to see how you have it set up.

Considering how close the objects are together, I'd probably forgo the drag interaction and use a clickable interaction. 

• Select your object to be sauced
• Select your sauce 
• Create a motion path to the object. You can add a turn state to the bottle that changes when the motion path animation is complete. And then have it return when the state of the bread is changed to sauced.

Something like that would work.

This may help with the state change, it's a download on SL by Jonathan Hill, it has twirling plates. If you open the SL file you can see step-by-step  how to achieve an animation with states and triggers. https://community.articulate.com/download/storyline-spinning-plates
