Editor Crash Log - Help Diagnosing

Questions & Answers
1

Hi

I have a very very sporadic crash in my game in the editor when i test my game. I have looked the error log and hold my hand up in regards to not really knowing how to diagnose the issue. Or in fact if there is enough information in there to pinpoint the problem. I have pasted the error log below and wondered if anyone with more experience could please take look and see if they can identify the potential problem.

In regards to where the crash I occurs. I have 2 prefabs for my character. Both instantiated and positioned. I set active state to false on the second one and when the user clicks the first that on is set to false and the second is set to true. The second one has an animation attached to it.

As mentioned it is extremely sporadic and most of the time it simply works but this occasional crash makes me nervous:/

This exact issue was happening with me this afternoon – Pretty much identical stack trace.

The source of the problem was a prefab with a Start() method that fetched an animator on a child component. I.e.,

void Start () {
    this.damageTextAnimator = this.damageText.GetComponent<Animator>();
}

In this case, “damageText” was a Unity 4.6 Text element, which I had set using the Unity Editor’s Inspector on the Prefab object.
