Create a copy of a class's instance by another class

Hi there,

I just wanna create a drag-to-copy script class to copy the existing mc on the stage (created from script) by control+drag and the new mc which is exactly like the original is shown up on a stage at a drop point. What I tried is to register the existing mc to the “drag-drop” class and the “drag-drop” class add functionality of the first class’s instance such as once you drag away existing mc, its copy will be created on the fly. My problem is inside the “drag-drop” class, I dont’ know how to get the reference of the first class mc to get another copy of itself with any property applied to it.

Thanks in advance
