UGUI检测射线穿透的方法

来源：互联网发布：菜鸟网络上市编辑：程序博客网时间：2024/05/18 01:06

一种是通过EventSystem的RaycastAll检测
一种是通过GraphicRaycaster的Raycast检测

这里写图片描述

+ 两种方法，代码如下

 public static bool IsPointerOverUIObject() {        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);        return results.Count > 0;    }public static bool IsPointerOverUIObject(Canvas canvas, Vector2 screenPosition){        PointerEventData eventDataCurrentPosition = new PointerEventData(EventSystem.current);        eventDataCurrentPosition.position = screenPosition;        GraphicRaycaster uiRaycaster = canvas.gameObject.GetComponent<GraphicRaycaster>();        List<RaycastResult> results = new List<RaycastResult>();        uiRaycaster.Raycast(eventDataCurrentPosition, results);        return results.Count > 0;}
