Debugging crashes in Unity with NoesisGUI
Posted: 31 May 2013, 18:23
Hey guys,
I'm running into a crash manipulating one of my UIs, and I'm trying find out what the issue is. It looks like the crash happens right after calling ScrollViewer.ScrollToHorizontalOffset. This makes me curious about a couple things.
First, is there anyway to shield Unity from errors in NoesisGUI? Right now a single binding or API getting invalid input takes down the entire editor process, which makes iteration a bit of a pain.
Second, I noticed a log file in the bin folder of the SDK. Is that from the runtime of NoesisGUI? I tried to get some information from that about my crash, but it doesn't look like it's plain text file. Do you have a custom application for viewing these logs? If so, are there plans to include this with the SDK so we can view them?
Here is stack trace that shows up in the Unity crash reporter logs:
