Carefully inspect the printed stack traces - they may contain hints about where the error occurred. To get a native stack trace, type bt all into the Xcode Debugger Console. Also, you generally can’t continue after these native (hardware memory access) faults happen. Native stack traces are a much more powerful tool for fault investigation but using them requires some expertise. The offending line might be something like the following: Instantiate(_imgThis might happen if, say, the script accesses an asset bundle without first checking that it was downloaded correctly. Also if it is script code then you will generally be told the exact line number (eg, “Da圜ontroller.js:122”). This indicates that the fault happened in the handleTimeOfDay method of the Da圜ontroller class, which works as a coroutine. Typical output might be: Unhandled Exception: System.NullReferenceException: A null value was found where an object instance was required.Īt Da圜ontroller+$handleTimeOfDay$121+$.MoveNext () in Da圜ontroller.js:122 NET exception text will be printed in the Xcode console (or else your code will just handle it in a “catch” statement). NET code then you won’t see EXC_BAD_ACCESS anymore. If everything was done right and the fault actually is occurring in. This feature affects script performance which is why it is enabled only for development builds (enable the “script debugging” option in build settings dialog). The AOT compiler includes quick checks for null references each time a method or variable is accessed on an object. Unity includes software-based handling of the NullReferenceException. There two ways to figure out where the fault happened: Managed stack traces This message typically appears on iOS devices when your application receives a NullReferenceException. The Xcode console shows "Program received signal: “SIGBUS” or EXC_BAD_ACCESS error. Information from the XCode Debugger console can often help detect these problems (Xcode menu: View > Debug Area > Activate Console). Errors in the native plugin interface (the managed code method signature does not match the native code function signature).
