Unity5个人版会添加Unity Logo作为启动画面，咱们既然没花钱，打个广告也应该。但Unity Logo结束后可以再添加一个自己的启动画面。

下面是添加一个简单的FadeIn->FadeOut过渡场景。

先看下效果图：

代码如下 LHSplashScreens.cs：

using UnityEngine; using System.Collections; public enum FadeStatus {  FadeIn,  FadeWaiting,  FadeOut } public class LHSplashScreens : MonoBehaviour  {  public string levelToLoad;  public bool waitForInput;  public float timeFadingInFinished;  public Sprite splashSprite;  private float m_fadeSpeed;  private float m_waitTime;  private float m_alpha;  private FadeStatus m_status;  private SpriteRenderer m_splashSpriteRenderer;  public LHSplashScreens()  {   levelToLoad = "";   m_fadeSpeed = 0.3f;   m_waitTime = 0.5f;   m_status = FadeStatus.FadeIn;  }  void Awake()  {   Application.targetFrameRate = 60;  }  // Use this for initialization  void Start ()   {   if (Application.levelCount <= 1 || levelToLoad == "")   {    Debug.LogWarning("Invalid levelToLoad value.");   }   GameObject m_splashSpriteGO = new GameObject("SplashSprite");   m_splashSpriteGO.AddComponent<SpriteRenderer>();   m_splashSpriteRenderer = m_splashSpriteGO.GetComponent<SpriteRenderer>();   m_splashSpriteRenderer.sprite = splashSprite;   Transform m_splashSpriteTransform = m_splashSpriteGO.gameObject.transform;   m_splashSpriteTransform.position = new Vector2(0f, 0f);   m_splashSpriteTransform.parent = this.transform;  }  // Update is called once per frame  void Update ()   {   FadeStatus fadeStatus = m_status;   if (fadeStatus == FadeStatus.FadeIn)   {    m_alpha += m_fadeSpeed * Time.deltaTime;   }   else if (fadeStatus == FadeStatus.FadeWaiting)   {    if ((!waitForInput && Time.time >= timeFadingInFinished + m_waitTime) || (waitForInput && Input.anyKey))    {     m_status = FadeStatus.FadeOut;    }   }   else if (fadeStatus == FadeStatus.FadeOut)   {    m_alpha -= m_fadeSpeed * Time.deltaTime;   }   UpdateSplashAlpha();  }  private void UpdateSplashAlpha()  {   if (m_splashSpriteRenderer != null)   {    Color spriteColor = m_splashSpriteRenderer.material.color;    spriteColor.a = m_alpha;    m_splashSpriteRenderer.material.color = spriteColor;    if (m_alpha > 1f)    {     m_status = FadeStatus.FadeWaiting;     timeFadingInFinished = Time.time;     m_alpha = 1f;    }    if (m_alpha < 0)    {     if (Application.levelCount >= 1 && levelToLoad != "")     {      Application.LoadLevel(levelToLoad);     }    }   }  } }
