Unity Ui点击事件实现

1.在Main Camera上 添加 Physics Raycaster组件

2.场景里需要有 EventSystem (Create - UI- EventSystem)

3.物体需要有Collider 

4.在需要点击的物体上挂脚本 并根据需求实现以下接口 以及方法

IPointerClickHandler    

IPointerDownHandler  

IPointerEnterHandler 

IPointerExitHandler  

IPointerUpHandler   

  

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

public class ColorPickerController : MonoBehaviour,IPointerClickHandler {


	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		
	}

	#region IPointerClickHandler implementation
	public void OnPointerClick (PointerEventData eventData)
	{
		Debug.Log ("点击");
		
	}
	#endregion
}
