<h2>构造函数</h2>
|
|
|
|
|
|
<h3>[name]( [param:LoadingManager manager] )</h3>
|
|
|
<p>
|
|
|
[page:LoadingManager manager] — 加载器使用的[page:LoadingManager loadingManager]。默认值为[page:LoadingManager THREE.DefaultLoadingManager]。
|
|
|
</p>
|
|
|
<p>
|
|
|
创建新的[name].

<h2>属性</h2>

<p>查看公共属性请参考基类[page:Loader]。</p>
|

|
<h2>方法</h2>
|
|
|
<p>查看公共方法请参考基类[page:Loader]。</p>
|
|
|
|
|
|
<h3>[method:DataTexture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
|
|
<p>
|
|
|
[page:String url] — 一个`.tga`文件的路径或者网络地址。<br />
|
|
|
[page:Function onLoad] — (可选的)加载成功之后调用的函数。该函数以[page:DataTexture]为参数。<br />
|
|
|
[page:Function onProgress] — (可选的)正在加载时调用的函数。参数为XMLHttpRequest实例，包含[page:Integer total]和[page:Integer loaded]。
|
|
|
如果服务没有设置Content-Length头，.[page:Integer total]的值为0。<br />
|
|
|
[page:Function onError] — (可选的)加载出现错误时调用的函数。该函将错误信息作为参数。<br />
|
|
|
</p>
|
|
|
<p>
|
|
|
开始加载[page:DataTexture texture]并传递给onLoad。即时引用会将[page:DataTexture texture]直接返回(不一定加载完成)。
