Question by Lance Sun · Mar 07, 2010 at 02:38 PM · crashupdateexceptionhandling

Some unhandled exceptions crash Unity

It seems that only unhandled exceptions thrown in the update loop will be logged. All other unhandled exceptions, such as those thrown in the Awake, or from another thread will crash Unity.

// caught and logged public void Update() { throw new Exception(); }

// crash public void Awake() { throw new Exception(); }

// crash public void Update() { var thread = new Thread(() => { throw new Exception(); }); thread.Start(); }

Given that swallowing an exception in Update() is relatively safe to do... in Awake() or another thread, that could leave the game in a very unknown state... What are some ways others are handling unhandled exceptions?

On which version of Unity are you seeing this? iPhone version, or regular? versionnumber?

I'm running Unity 4.5, and nullpointer exceptions thrown in the Start() function seem to be swallowed somehow in the editor. On android, however, the error is visible in logcat, but the game still runs, but not like it's supposed to be. This makes things hard to debug.
