How do I access an asset field in the 'onSaveEntry' event? I'm listening on an entries save event with:

craft()-&gt;on('entries.saveEntry', function(Event $event) {
  //$event-&gt;params['entry']); -&gt; passes to function 
});


How can I assess assets that are also part of that saved entry?

$event-&gt;params['entry']-&gt;getContent()-&gt;{fieldname} doesn't give me the array with information I was hoping for.
This gives you an EntryModel:

$entryModel = $event-&gt;params['entry'];


This will give you an array of AssetFileModels:

$assetFileModels = $entryModel-&gt;myAssetFieldHandle


You can loop through them like so:

foreach ($assetFileModels as $assetFileModel)
{
    $url = $assetFileModel-&gt;getUrl();
}
