MonoBehaviour.OnMouseOver()

Descripción

Llamado cada frame mientras que el mouse está sobre el GUIElement o Collider.

A call to OnMouseEnter occurs on the first frame the mouse is over the object. OnMouseOver is then called each frame until the mouse moves away, at which point OnMouseExit is called.

Esta función no es llamada en objetos que pertenezcan a la layer (capa) Ignore Raycast.

Esta función se llama en los Colliders marcados como Trigger si y solo sí Physics.queriesHitTriggers es true.

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.

//Attach this script to a GameObject to have it output messages when your mouse hovers over it.
using UnityEngine;

public class OnMouseOverExample : MonoBehaviour
{
    void OnMouseOver()
    {
        //If your mouse hovers over the GameObject with the script attached, output this message
        Debug.Log("Mouse is over GameObject.");
    }

    void OnMouseExit()
    {
        //The mouse is no longer hovering over the GameObject so output this message each frame
        Debug.Log("Mouse is no longer on GameObject.");
    }
}

//This second example changes the GameObject's color to red when the mouse hovers over it
//Ensure the GameObject has a MeshRenderer

using UnityEngine;

public class OnMouseOverColor : MonoBehaviour
{
    //When the mouse hovers over the GameObject, it turns to this color (red)
    Color m_MouseOverColor = Color.red;
    //This stores the GameObject’s original color
    Color m_OriginalColor;
    //Get the GameObject’s mesh renderer to access the GameObject’s material and color
    MeshRenderer m_Renderer;

    void Start()
    {
        //Fetch the mesh renderer component from the GameObject
        m_Renderer = GetComponent<MeshRenderer>();
        //Fetch the original color of the GameObject
        m_OriginalColor = m_Renderer.material.color;
    }

    void OnMouseOver()
    {
        //Change the color of the GameObject to red when the mouse is over GameObject
        m_Renderer.material.color = m_MouseOverColor;
    }

    void OnMouseExit()
    {
        //Reset the color of the GameObject back to normal
        m_Renderer.material.color = m_OriginalColor;
    }
}
