<h2>代码示例</h2>
|
|
|
|
|
|
<code>
|
|
|
// 初始化一个监听
|
|
|
const audioListener = new THREE.AudioListener();
|
|
|
|
|
|
// 把监听添加到camera
|
|
|
camera.add( audioListener );
|
|
|
|
|
|
// 初始化音频对象
|
|
|
const oceanAmbientSound = new THREE.Audio( audioListener );
|
|
|
|
|
|
// 添加一个音频对象到场景中
|
|
|
scene.add( oceanAmbientSound );
|
|
|
|
|
|
// 初始化一个加载器
|
|
|
const loader = new THREE.AudioLoader();
|
|
|
|
|
|
// 加载资源
|
|
|
loader.load(
|
|
|
// 资源URL
|
|
|

|
|
|
|
|
// onLoad回调

|
|
|
// 给一个加载器对象设置音频对象的缓存
|
|

|
|
|
|
|
// 播放音频
|
|
|
oceanAmbientSound.play();

// onProgress回调
|
|

|
<h2>方法</h2>
|
|
|
<p>共有方法请参见其基类[page:Loader]。</p>
|

|
|
|
|
<h3>[method:undefined load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
|
|
<p>
|
|
|
[page:String url] — 文件的URL或者路径，也可以为
|
|
|
[link:https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Data_URIs Data URI].<br />
|
|
|
[page:Function onLoad] — 加载完成时将调用。回调参数为将要加载的响应文本。<br />
|
|
|
[page:Function onProgress] — 将在加载过程中进行调用。参数为XMLHttpRequest实例，实例包含[page:Integer total]和[page:Integer loaded]字节.<br />
|
|
|
[page:Function onError] — 在加载错误时被调用。<br />
|
|
|
</p>
|
|
|
<p>
|
|
