How to drag with physics 2?

Why can’t I drag objects when I have the two behaviors, draggable object and physics2.Or is there another way?

You can disable a behavior with events =)
You can’t because Physic and draggable system use both the position of your object in same time, so this is a conflict.

So for example if the object already falls on the platform, the object’s physic behavior would be disabled and draggable would be activated? Thank you~

You choose with the condition how you want switch between two behaviors.
It depends on what you want to do.
