function OnMouseDrag () : void


OnMouseDrag is called when the user has clicked on a GUIElement or Collider and is still holding down the mouse.

OnMouseDrag is called every frame while the mouse is down.

// Darken the material color while user holds down the mouse.
function OnMouseDrag () {
renderer.material.color -= Color.white * Time.deltaTime;

This function is not called on objects that belong to Ignore Raycast layer.

OnMouseDrag can be a co-routine, simply use the yield statement in the function. This event is sent to all scripts attached to the Collider or GUIElement.
