<h2>Methods</h2>
|
||
|
|
<p>See the base [page:Loader] class for common methods.</p>
|
||
|
|
|
||
|
|
<h3>[method:DataTexture load]( [param:String url], [param:Function onLoad], [param:Function onProgress], [param:Function onError] )</h3>
|
||
|
|
<p>
|
||
|
|
[page:String url] — A string containing the path/URL of the `.tga` file. <br />
|
||
|
|
[page:Function onLoad] — (optional) A function to be called after loading is successfully completed. The function receives loaded [page:DataTexture] as an argument.<br />
|
||
|
|
[page:Function onProgress] — (optional) A function to be called while the loading is in progress. The argument will be the XMLHttpRequest instance, which contains .[page:Integer total] and .[page:Integer loaded] bytes. If the server does not set the Content-Length header; .[page:Integer total] will be 0.<br />
|
||
|
|
[page:Function onError] — (optional) A function to be called if an error occurs during loading. The function receives the error as an argument.<br />
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Begin loading from url and pass the loaded [page:DataTexture texture] to onLoad. The [page:DataTexture texture] is also directly returned for immediate use (but may not be fully loaded).
