function OnMouseOver () : void


OnMouseOver is called every frame while the mouse is over the GUIElement or Collider.

// Fades the red component of the material to zero
// while the mouse is over the mesh
function OnMouseOver () {
renderer.material.color.r -= 0.1 * Time.deltaTime;

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

OnMouseOver 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.
