public bool IsPointerOverGameObject ();
public bool IsPointerOverGameObject (int pointerId);

パラメーター

pointerIdPointer (touch / mouse) ID.

説明

Is the pointer with the given ID over an EventSystem object?

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;

public class MouseExample : MonoBehaviour { void Update() { // Check if the left mouse button was clicked if (Input.GetMouseButtonDown(0)) { // Check if the mouse was clicked over a UI element if (EventSystem.current.IsPointerOverGameObject()) { Debug.Log("Clicked on the UI"); } } } }

If you use IsPointerOverGameObject() without a parameter, it points to the "left mouse button" (pointerId = -1); therefore when you use IsPointerOverGameObject for touch, you should consider passing a pointerId to it.

using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;

public class TouchExample : MonoBehaviour { void Update() { // Check if there is a touch if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) { // Check if finger is over a UI element if (EventSystem.current.IsPointerOverGameObject(Input.GetTouch(0).fingerId)) { Debug.Log("Touched the UI"); } } } }

Note that for touch, IsPointerOverGameObject should be used with OnMouseDown() or Input.GetMouseButtonDown(0) or Input.GetTouch(0).phase == TouchPhase.Began.
