Join Kelley Hecker for an in-depth discussion in this video Understanding the MonoBehaviour game loop, part of Unity: Scripting with C#.
- Different MonoBehaviour functions are called…at certain times during your games execution.…As you can see, there are a lot of…events called on MonoBehaviours.…I encourage you to look at the Unity Documentation…to find the events most suited for what…you're trying to achieve.…I'll be talking about the three most used functions.…Awake, Start, and Update.…Awake is called once, when the scene is first loaded,…before start or update.…Awake is a good place to initialize variables…that this script or other scripts will…try to access in Start.…
This is because you can't guarantee that one script's…start Start function will be called before another's.…If you initialized a variable in Start,…there's a chance that it may not have been created yet…when the other script tries to access it,…resulting in an error.…Speaking of Start.…Start is called once,…after Awake and before the first Update call.…Since Start is only called once per object,…and is called before Update,…it's a good place to set up any references you need.…Anything that only needs to happen once,…

Q: Why am I getting a script compile error when trying to load the exercise files?
A: This course was recorded in Unity 4.6, and Unity has since released Unity 5. There are two items to address for Unity 5 users.
Q: Why can't I see the Render Settings option in the Edit menu?
A: The Render Settings options have been moved in Unity 5. You can access them by going to the Window menu and choosing Lighting. In the window that loads, Render Settings can be found under the Scene tab.
