Pico 淡入淡出

作者:互联网

关于Unity 开发Pico 的淡入淡出功能  (适用于和我一样刚入门的新手)

废话少说  直接上流程

在Pvr_UnitySDK--Head--下面创建个空物体FadeInOutControl(名字可以随意取)
在FadeInOutControl下创建两个子物体 一个叫FadeIn 另一个叫FadeOut
将两个子物体上添加Sprite Renderer   并附一张图片
FadeIn 的Color 设置为(0,0,0,255)   FadeOut的Color 设置为(0,0,0,0)

在FadeIn物体添加“FadeIn”脚本  脚本如下

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

public class FadeIn : MonoBehaviour {

    private void OnEnable()
    {
        this.GetComponent<SpriteRenderer>().color = new Color
                (this.GetComponent<SpriteRenderer>().color.r,
                this.GetComponent<SpriteRenderer>().color.g,
                this.GetComponent<SpriteRenderer>().color.b,
                1
                );

    }
    void Update()
    {
        //如果透明度大于零,减少,在此前提下,最后一次执行如果小于零,等于零
        if (this.GetComponent<SpriteRenderer>().color.a > 0)
        {
            this.GetComponent<SpriteRenderer>().color = new Color
                (this.GetComponent<SpriteRenderer>().color.r,
                this.GetComponent<SpriteRenderer>().color.g,
                this.GetComponent<SpriteRenderer>().color.b,
                this.GetComponent<SpriteRenderer>().color.a - 0.02f
                );
            if (this.GetComponent<SpriteRenderer>().color.a < 0)
            {
                this.GetComponent<SpriteRenderer>().color = new Color
                (this.GetComponent<SpriteRenderer>().color.r,
                this.GetComponent<SpriteRenderer>().color.g,
                this.GetComponent<SpriteRenderer>().color.b,
                0
                );
                //在最后一次执行后,关闭物体
                this.gameObject.SetActive(false);
            }
        }

    }
}

在FadeOut物体添加“FadeOut”脚本 脚本如下

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

public class FadeOut : MonoBehaviour {

    private void OnEnable()
    {
        this.GetComponent<SpriteRenderer>().color = new Color
               (this.GetComponent<SpriteRenderer>().color.r,
               this.GetComponent<SpriteRenderer>().color.g,
               this.GetComponent<SpriteRenderer>().color.b,
               0
               );
    }

    void Update()
    {
        //如果透明度大于零,减少,在此前提下,最后一次执行如果小于零,等于零
        if (this.GetComponent<SpriteRenderer>().color.a < 1)
        {
            this.GetComponent<SpriteRenderer>().color = new Color
                (this.GetComponent<SpriteRenderer>().color.r,
                this.GetComponent<SpriteRenderer>().color.g,
                this.GetComponent<SpriteRenderer>().color.b,
                this.GetComponent<SpriteRenderer>().color.a + 0.02f
                );
            if (this.GetComponent<SpriteRenderer>().color.a > 1)
            {
                this.GetComponent<SpriteRenderer>().color = new Color
                (this.GetComponent<SpriteRenderer>().color.r,
                this.GetComponent<SpriteRenderer>().color.g,
                this.GetComponent<SpriteRenderer>().color.b,
                1
                );
                //在最后一次执行后,关闭物体
                //this.gameObject.SetActive(false);
            }
        }
    }
}

在FadeInOutControl物体添加“Control_FadeInOut_Panel”脚本  并将两个子物体拖拽进去  脚本如下

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

public class Control_FadeInOut_Panel : MonoBehaviour {

    public static Control_FadeInOut_Panel Instance;

    public GameObject FadeInPanel;
    public GameObject FadeOutPanel;

    private void Awake()
    {
        Instance = this;
    }

	void Update () {
		
	}
    //开启执行一次淡入
    public void OpenFade_In_Panel() {
        FadeInPanel.SetActive(true);
    }
    //开启执行一次淡出
    public void OpenFade_Out_Panel()
    {
        FadeOutPanel.SetActive(true);
    }
    //关闭淡入界面
    public void CloseFade_In_Panel()
    {
        FadeInPanel.SetActive(false);
    }
    //关闭淡出界面
    public void CloseFade_Out_Panel()
    {
        FadeOutPanel.SetActive(false);
    }

}

使用方法  调用Control_FadeInOut_Panel 里的方法就可以了  如:
Control_FadeInOut_Panel.Instance.CloseFade_Out_Panel();
Control_FadeInOut_Panel.Instance.OpenFade_In_Panel();
