Description

要实现的接口(如果您希望接收 OnPointerDown 回调)。

检测正在进行的鼠标单击,直到松开鼠标按钮。使用 IPointerUpHandler 来处理鼠标按钮的释放。

//Attach this script to the GameObject you would like to have mouse clicks detected on
//This script outputs a message to the Console when a click is currently detected or when it is released on the GameObject with this script attached

using UnityEngine; using UnityEngine.EventSystems;

public class Example : MonoBehaviour, IPointerDownHandler, IPointerUpHandler { //Detect current clicks on the GameObject (the one with the script attached) public void OnPointerDown(PointerEventData pointerEventData) { //Output the name of the GameObject that is being clicked Debug.Log(name + "Game Object Click in Progress"); }

//Detect if clicks are no longer registering public void OnPointerUp(PointerEventData pointerEventData) { Debug.Log(name + "No longer being clicked"); } }
