遍历所有子物体中renderer(渲染器)中的material(材质)并改变其alpha值实现若隐若现的效果
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class CubeControl : MonoBehaviour
{
public GameObject Cube;
private float rotaSpeed=5f;
void Update ()
{
//得到所有可渲染的子物体
Renderer[] rds = Cube.GetComponentsInChildren<Renderer>();
//逐一遍历他的子物体中的Renderer
foreach (Renderer render in rds)
{
//逐一遍历子物体的子材质(renderer中的material)
foreach (Material material in render.materials)
{
var r = material.color.r;
var g = material.color.g;
var b = material.color.b;
var alpha = Mathf.PingPong(Time.time / 5f, 1);
material.color = new Color(r, g, b, alpha);
}
}
//Cube自转
Cube.transform.Rotate(new Vector3(0, -1, 0), Time.deltaTime * rotaSpeed);
}
