Drag and drop help

i’m hoping someone can help me with a drag and drop exercise.

lets say i have movie clip a (mca) and i want to drag it on top of of movie clip b (mcb)

ideally, mca will trigger an over event for mcb when hovering over it (the same way folders do on your desktop when you drop files in them. On release, mca would disappear and mcb would show its up state.

to take it one step further, if you double click mcb, it will open a new window, revealing its contents—mca in this case.

this is far too advanced for me, so I’m really hoping someone can please help :slight_smile:
