RawImage logo = mainLogo.transform.FindChild("back/headBack/Logo").GetComponent<RawImage>();

void Update()
{

var r = logo.color.r;
var g = logo.color.g;
var b = logo.color.b;
var alpha = Mathf.PingPong(Time.time / 5f, 1);
logo.color = new Color(r, g, b, alpha);

}

 

//在unity简单使用案例

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class fade : MonoBehaviour
{
　　private Image image;
　　void Start()
　　{
　　　　image = GameObject.Find("Canvas/Image").GetComponent<Image>();
　　}

　　void Update()
　　{
　　　　var r = image.color.r;
　　　　var g = image.color.g;
　　　　var b = image.color.b;
　　　　var alpha = Mathf.PingPong(Time.time / 5f, 1);
　　　　image.color = new Color(r, g, b, alpha);
