#1 Draggable Behavior Pointer Events
In this article we will do a little setup and then spend the majority of time focusing on
dealing with user input, in our case both pointer up and pointer down, as it relates to
our draggable behavior. We will first see how we wire up our event handlers using the Unity
editor and once we have a better understanding of that process we will proceed to wire them
up programatically so that we do not have to do the manual steps everytime we add our draggable
behavior to an object.
