OnMouseEnter is called when the mouse entered the GUIElement or Collider.

	// Attach this script to a mesh to make
	// it red when the mouse is over the mesh

function OnMouseEnter () { renderer.material.color = Color.red; }
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void OnMouseEnter() {
        renderer.material.color = Color.red;
import UnityEngine
import System.Collections

public class ExampleClass(MonoBehaviour):

	def OnMouseEnter() as void:
		renderer.material.color = Color.red

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

OnMouseEnter 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.
