Question

我在Pushbutton Engine中使用EventSoundTrigger遇到了一些问题

我可以使用xml这样工作：

 <component type="com.pblabs.components.basic.EventSoundTrigger" name="Sounds">
     <startSound filename="/assets/explosion.mp3" />
   </component>

但是，如果我尝试编写动作脚本来做同样的错误。我在网上找不到任何示例来解释如何在ActionScript中直接初始化或使用EventSoundTrigger。

以下引发了在创建组件时声音对象为空的错误。

我在这里找到了答案：

   var et:EventSoundTrigger = new EventSoundTrigger();
    et.startSound = PBE.resourceManager.load("assets/noo.mp3", MP3Resource , onLoaded, onFailed) as MP3Resource ;
    var tEntity:IEntity = PBE.allocateEntity();
    tEntity.addComponent( et , "sound" ) ;
    tEntity.initialize("tsound");

Answer 1

似乎当EventSoundTrigger组件添加到实体时，它需要startSound资源准备就绪。为此，您可以先加载资源，然后创建组件：

PBE.resourceManager.load("assets/02.mp3", MP3Resource, onLoaded, onFailed) as MP3Resource;

private function onLoaded(resource:MP3Resource):void
{
    var et:EventSoundTrigger = new EventSoundTrigger();
    et.startSound = resource;
    var tEntity:IEntity = PBE.allocateEntity();
    tEntity.addComponent( et , "sound" ) ;
    tEntity.deferring=false;
}
