Called when the mouse enters the GUIElement or Collider.
The corresponding OnMouseOver function is called while the mouse stays over the object and OnMouseExit is called when it moves away.
// Change the mesh color in response to mouse actions.
using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public Renderer rend;
void Start() { rend = GetComponent<Renderer>(); }
// The mesh goes red when the mouse is over it... void OnMouseEnter() { rend.material.color = Color.red; }
// ...the red fades out to cyan as the mouse is held over... void OnMouseOver() { rend.material.color -= new Color(0.1F, 0, 0) * Time.deltaTime; }
// ...and the mesh finally turns white when the mouse moves away. void OnMouseExit() { rend.material.color = Color.white; } }
This function is not called on objects that belong to Ignore Raycast layer.
This function is called on Colliders marked as Trigger if and only if Physics.queriesHitTriggers is true.
OnMouseEnter can be a co-routine, simply use the yield statement in the function.
