IPointerEnterHandler

描述

要实现的接口（如果您希望接收 OnPointerEnter 回调）。

用于检测鼠标何时开始悬停在某个游戏对象上。要检测鼠标何时停止悬停在游戏对象上，请使用 IPointerExitHandler。

//Attach this script to the GameObject you would like to have mouse hovering detected on
//This script outputs a message to the Console when the mouse pointer is currently detected hovering over the GameObject and also when the pointer leaves.

using UnityEngine;
using UnityEngine.EventSystems;

public class Example : MonoBehaviour, IPointerEnterHandler, IPointerExitHandler
{
    //Detect if the Cursor starts to pass over the GameObject
    public void OnPointerEnter(PointerEventData pointerEventData)
    {
        //Output to console the GameObject's name and the following message
        Debug.Log("Cursor Entering " + name + " GameObject");
    }

    //Detect when Cursor leaves the GameObject
    public void OnPointerExit(PointerEventData pointerEventData)
    {
        //Output the following message with the GameObject's name
        Debug.Log("Cursor Exiting " + name + " GameObject");
    }
}
