Drop target states
I don't use freeform.
So I have 5 drop targets. I have 10 dragable objects. Any of these objects can be dropped on any target.
Each of dragable objects have state - Dropped correct - same to Normal - just to verify that object was dropped on. Also it has real correct/incorrect states that are revealed on clicking Submit.
Trigger - change of obj1 to correct if state of obj1 equals to dropped correct.
All I need is to prevent other object tobe dropped on busy drop target.
So question is :
Is it any buit-in states for drop targets to know if target is busy or free?
