Mono BehaviorCan be attached to game objectsUnity Calls MonoBehaviorInitializationAwake(): called for every MonoBbehaviorStart(): called for every MonoBehaviour after all the Awake()sGame Loop callsUpdate(): called in every frame, most things happens hereLateUpdate(): called after every Update()s are exceted. Use for, e.g., follow cameraFixedUpdate(): use for physics thing, e.g., RagDoll handlingOnGUI(), for GUI drawing, can be called several times in each frame Other useful things: Invoke(), InvokeRepeating(), StartCouroutine()Getting Started with Unity

34. Code OptimizingKeep Update(), FixedUpdate(), LateUpdate(), OnGUI() cleanAvoid object lookups, e.g., GameObject.Find() calls within theseCache lookup results when possibleUse MonoBehaviour.enabled to disable/enable MonoBehavior if you do not want to execute Update(), …MonoBehaviour.Invoke(), MonoBehaviour.InvokeRepeating() and Couroutines are alternative to Update()Functionality is not needed to execute in every frameE.g., use InvokeRepeating() to execute of function for every 0.5sDo not add empty Update(), FixedUpdate(), LateUpdate(), OnGUI() Call overhead!Getting Started with Unity
