一、添加背景音乐

#添加全局播放插件（注意文件如果不存在从krpano程序目录中复制）
<plugin name="soundinterface" url="%SWFPATH%/plugins/soundinterface.swf" alturl="%SWFPATH%/plugins/soundinterface.js" rootpath="" preload="true" keep="true" volume="0.6"/>

#添加音乐
<action name="startup" autorun="onstart">
    ....   
    playsound(bgsnd, 'audio/bg.mp3', 0);
</action>  
#bgsnd代表声音id，名字不要和其它id冲突， 0代表循环，1代表播放一次

二、添加每个场景解说

#添加一的全局插件
#添加action
 <events name="audioscene" keep="true" onnewscene="ChangeScene();"/>
 <action name="ChangeScene">
     set(_audiourl, calc:'audio/' + scene[get(xml.scene)].sound + '.mp3');
     playsound(curaudio, get(_audiourl));
 </action>
 在每个scene添加音乐名称（不带.mp3后缀）
 <scene name="scene_1" .... sound="mp3name">

多个场景同一个解说（多个场景切换时不中断解说）

#添加一的全局插件
<skin_setting 添加 musicgroup="0"
<scene 添加 group="1或2" scenemusic="scene1music.mp3"
外部添加
<events name="scene1events" keep="true"
    onxmlcomplete="
    ifnot(scene[get(xml.scene)].group == skin_settings.musicgroup,
    playsound(scenesound, get(scene[get(xml.scene)].scenemusic),1);
    copy(skin_settings.musicgroup,scene[get(xml.scene)].group));" 
     />

三、在场景中添加播放按钮

#添加一的全局插件
#复制showtext.xml 到/plugins
#添加播放按钮图片 ypopen.png，ypclose.png 到/

<krpano 添加now_play="">
<include url="%SWFPATH%/plugins/showtext.xml" />
<style name="skin_soundbutton" url="ypopen.png"  onhover="showtext(get(text),STYLE2);" distorted="true"
               onclick="stopallsounds();
               if(url == ypopen.png,
                   playsound(get(name),get(sound),1);if(now_play != name, set(hotspot[get(now_play)].url,ypopen.png););set(now_play,get(name)),
                   stopsound(get(name));
                   );
               switch(url,ypopen.png,ypclose.png);"  />  

        <textstyle name="STYLE2"
               font="Arial" fontsize.no-mobile="18" fontsize.mobile="28" bold="true"
               background="false" border="false"
               textcolor="0xFFFFFF"
               textalign="center"
               textshadow="0.01" textshadowrange="3" textshadowcolor="0x000000"
               yoffset.touch="-40"
               />

二、B 添加每个场景解说方法2（第一次启动里有一个开始按钮，防止浏览器第一次不启动音乐播放）

#添加一的全局插件
 <!--  开始按钮  -->
<layer name="splash" type="text" keep="true" zorder="100" align="center" html="开始" vcenter="true" padding="20" onclick="FirstStart"/>
 <!--  遮罩层  -->
<layer name="dip" keep="true" type="container" align="lefttop" width="100%" height="100%" bgcolor="0x000000" bgalpha="1"/>
<action name="FirstStart">
set(_audiourl, calc:'audio/' + scene[get(xml.scene)].sound + '.mp3'); playsound(curaudio, get(_audiourl)); tween(plugin[soundinterface].volume,1,2); removelayer(splash); tween(layer[dip].alpha,0,2,,removelayer(dip));
</action>
<plugin name="soundinterface" keep="true" url="plugins/soundinterface.js" preload="true" volume="1" mute="false"/>
<action name="ChangeScene">
loadscene(%1); set(_audiourl, calc:'audio/' + scene[get(xml.scene)].sound + '.mp3'); playsound(curaudio, get(_audiourl));
</action>

 <!--  audio1 is the name of the mp3 in the audio folder  -->
<scene name="scene_1" ... autoload="true" sound="audio1">
...
<hotspot name="spot1" url="VT.png" ath="0" atv="0" onclick="ChangeScene(scene_2);"/>
</scene>
<scene name="scene_2" ... sound="audio2">
...
<hotspot name="spot1" url="VT.png" ath="0" atv="0" onclick="ChangeScene(scene_1);"/>
</scene>
