Unity3D笔记 愤怒的小鸟<四> 实现Selelction界面

　　一直跟着龚老师用js写，VS智能感应用习惯后发现这里用js对初学者比较蛋疼，MONO有提示但是还是无法和VS媲美就目前来看。所以这次还是换成熟悉的VS来开发。

　　目标：实现关卡页面

　　 跑起来的效果如下：

　　 

　　方法和之前添加图片一样，先创建GUITexture背景图片，再创建GUISkin 用于创建上图中7个图片按钮。手型鼠标直接把上节的customCusor.js

拿来即可，背景音乐选择Main Camera->Component->Audio->Audio Source

　　C#代码如下　　

using UnityEngine;
using System.Collections;

public class selectGUI : MonoBehaviour
{
    public GUISkin mySkin;
    /// <summary>
    /// 返回按钮
    /// </summary>
    private Rect backPosition = new Rect(40, 280, 50, 50);
    /// <summary>
    /// 按钮1
    /// </summary>
    private Rect level1Position = new Rect(60, 10, 100, 100);
    /// <summary>
    /// 按钮2
    /// </summary>
    private Rect level2Position = new Rect(220, 10, 100, 100);
    /// <summary>
    /// 按钮3
    /// </summary>
    private Rect level3Position = new Rect(380, 10, 100, 100);
    /// <summary>
    /// 按钮4
    /// </summary>
    private Rect level4Position = new Rect(60, 160, 100, 100);
    /// <summary>
    /// 按钮5
    /// </summary>
    private Rect level5Position = new Rect(220, 160, 100, 100);
    /// <summary>
    /// 按钮6
    /// </summary>
    private Rect level6Position = new Rect(380, 160, 100, 100);
    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {

    }

    void OnGUI()
    {
        GUI.skin = mySkin;
        if (GUI.Button(level1Position,"",GUI.skin.GetStyle("LevelButton1")))
        {
            Application.LoadLevel(4);
        }
        if (GUI.Button(level2Position, "", GUI.skin.GetStyle("LevelButton2")))
        {
            Application.LoadLevel(4);
        }
        if (GUI.Button(level3Position, "", GUI.skin.GetStyle("LevelButton3")))
        {
            Application.LoadLevel(4);
        }
        if (GUI.Button(level4Position, "", GUI.skin.GetStyle("LevelButton4")))
        {
            Application.LoadLevel(4);
        }
        if (GUI.Button(level5Position, "", GUI.skin.GetStyle("LevelButton5")))
        {
            Application.LoadLevel(4);
        }
        if (GUI.Button(level6Position, "", GUI.skin.GetStyle("LevelButton6")))
        {
            Application.LoadLevel(4);
        }
        if (GUI.Button(backPosition, "", GUI.skin.GetStyle("BackButton")))
        {
            Application.LoadLevel(2);
        }
    }
}

　　一点要注意在JS中var mySkin:GUISkin 表示公共的变量在C#中默认是私有变量所以要写出public GUISkin mySkin; 这点小区别注意。

　　

　　成功跑起来后就可以把之前的三个场景Sences组合起来跑一次
