.threadPriority

 

 

Description

Priority of decompression thread.

You can control decompression speed vs. impact on frame rate tradeoff when downloading Asset Bundles in the background. When using lower priority, decompression will take longer, but will not have such a big impact on frame rates. Default value is ThreadPriority.Normal.

function Start () {    var www = new  ("http://myserver/myBundle.unity3d");    www.threadPriority = ;    yield www;    // Get the designated main asset and instantiate it.    Instantiate(www.assetBundle.mainAsset);}
