Unity3D学习记录——API工具类3

1.还是Mathf数学类应用，制作渐隐黑屏效果，配合GameOver

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

public class Background : MonoBehaviour {

    public GUITexture m_background; //定义GUITexture组件公共对象m_background

	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
        m_background.color = new Color(0f, 0f, 0f, Mathf.Lerp(0.0f, 1.0f, Time.time * 0.1f)); //这是透明度改变的操作，透明度在Color属性里，三个0f表示RGB色，最后透明度在10s时间从全透明到全不透明
	}
}
