A convenient class for loading models from disk, in bam or egg format (or any of a number of other formats implemented by a LoaderFileType, such as ptloader).
This class supports synchronous as well as asynchronous loading. In asynchronous loading, the model is loaded in the background by a thread, and an event will be generated when the model is available. If threading is not available, the asynchronous loading interface may be used, but it loads synchronously.

| void Loader::save_async |
( |
AsyncTask * |
request | ) |
|
|
inline |
Begins an asynchronous save request.
To use this call, first call make_async_save_request() to create a new ModelSaveRequest object with the filename you wish to load, and then add that object to the Loader with save_async. This function will return immediately, and the model will be loaded in the background.
To determine when the model has completely loaded, you may poll request->is_ready() from time to time, or set the done_event on the request object and listen for that event. When the request is ready, you may retrieve the success or failure via request->get_success().
