因为经常有点击空白区域关闭当前页面的需求,写了个简单点的工具类,可以添加一些界面关闭时的自定义事件,用的话,要关闭哪个就把脚本挂到哪个上就行。
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;
public class CloseSlefLogic : MonoBehaviour
{
public UnityEvent closeHandle;
private GameObject nowClick;
void Update()
{
if (Input.GetMouseButtonDown(0))
{
nowClick = ClickObject();
if (nowClick == null || (nowClick != gameObject && nowClick.transform.parent != transform))
{
closeHandle.Invoke();
}
}
}
public GameObject ClickObject()
{
PointerEventData eventDataCurrentPosition = new PointerEventData(EventSystem.current);
eventDataCurrentPosition.position = new Vector2(Input.mousePosition.x, Input.mousePosition.y);
List<RaycastResult> results = new List<RaycastResult>();
EventSystem.current.RaycastAll(eventDataCurrentPosition, results);
if (results.Count > 0)
{
return results[0].gameObject;
}
else
{
return null;
}
}
}
