Drawing and drag/drop objects in EditorWindow (like scene view) in 5.3

Hi Developers,

I would like to do my own little scene view in a custom editor window,
like drag and drop sprites and models to manipulate them.

Is it possible and how?

 

It is possible. The how depends on your needs.
In general, you'll be making an editor window, and working with its events during your OnGUI().
You'll probably need a camera, one that will provide you with the rendering of your models / sprites.
Controls around the scene view will move the camera to change viewing perspective.
