NGUI按钮控制乐曲的播放和停止

单个按钮的

控制脚本（“QieHuan”）和声源(AudioSource)加在NGUI按钮上，如图

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

public class QieHuan : MonoBehaviour
 {
      private bool isCanPlay=true;
      public void ClickBtn()
      {
            if (isCanPlay)
            {
                gameObject.GetComponent().spriteName = "播放";
                gameObject.GetComponent().normalSprite = "播放";//需要把UIButton脚本里normalSprite一块儿改了
                gameObject.GetComponent().Play();
                isCanPlay1 = false;
            }
            else
            {
                gameObject.GetComponent().spriteName = "停止";
                gameObject.GetComponent().normalSprite = "停止";
                gameObject.GetComponent().Stop();
                isCanPlay = true;
            }
      }
}

三个按钮的

需对按钮上的控制脚本进行修改

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

public class QieHuan : MonoBehaviour {
    public GameObject btn1;
    public GameObject btn2;
    public GameObject btn3;
    public static bool isCanPlay1=true;
    public static bool isCanPlay2=true;
    public static bool isCanPlay3 = true;
   // public bool l;
    // Use this for initialization
    void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		
	}
    public void ClickBtn()
    {
       
        if (gameObject.name == "btn1")
        {
            btn2.GetComponent().spriteName = "停止";
            btn2.GetComponent().normalSprite = "停止";
            btn2.GetComponent().Stop();
            isCanPlay2 = true;

            btn3.GetComponent().spriteName = "停止";
            btn3.GetComponent().normalSprite = "停止";
            btn3.GetComponent().Stop();
            isCanPlay3 = true;

            if (isCanPlay1)
            {
                gameObject.GetComponent().spriteName = "播放";
                gameObject.GetComponent().normalSprite = "播放";
                gameObject.GetComponent().Play();
                isCanPlay1 = false;
            }
            else
            {
                gameObject.GetComponent().spriteName = "停止";
                gameObject.GetComponent().normalSprite = "停止";
                gameObject.GetComponent().Stop();
                isCanPlay1 = true;
            }
        }
        if (gameObject.name == "btn2")
        {
            btn3.GetComponent().spriteName = "停止";
            btn3.GetComponent().normalSprite = "停止";
            btn3.GetComponent().Stop();
            isCanPlay3 = true;
            btn1.GetComponent().spriteName = "停止";
            btn1.GetComponent().normalSprite = "停止";
            btn1.GetComponent().Stop();
            isCanPlay1 = true;
            //Debug.Log(isCanPlay1);

            if (isCanPlay2)
            {
                gameObject.GetComponent().spriteName = "播放";
                gameObject.GetComponent().normalSprite = "播放";
                gameObject.GetComponent().Play();
                isCanPlay2= false;
            }
            else
            {
                gameObject.GetComponent().spriteName = "停止";
                gameObject.GetComponent().normalSprite = "停止";
                gameObject.GetComponent().Stop();
                isCanPlay2 = true;
            }
        }
        if (gameObject.name == "btn3")
        {
            btn1.GetComponent().spriteName = "停止";
            btn1.GetComponent().normalSprite = "停止";
            btn1.GetComponent().Stop();
            isCanPlay1 = true;
            btn2.GetComponent().spriteName = "停止";
            btn2.GetComponent().normalSprite = "停止";
            btn2.GetComponent().Stop();
            isCanPlay2 = true;
            //Debug.Log(isCanPlay1);

            if (isCanPlay3)
            {
                gameObject.GetComponent().spriteName = "播放";
                gameObject.GetComponent().normalSprite = "播放";
                gameObject.GetComponent().Play();
                isCanPlay3 = false;
            }
            else
            {
                gameObject.GetComponent().spriteName = "停止";
                gameObject.GetComponent().normalSprite = "停止";
                gameObject.GetComponent().Stop();
                isCanPlay3= true;
            }
        }


    }
}

以下为实际项目中的截图和代码（用另一套逻辑，实现三个乐曲的切换，并伴随相应乐谱图片的切换）——代码仍然是加在每个Button上，因为还涉及到一首曲子中有两张乐谱图片情况，细节没有完全展开，仅做参考，请勿套用
