UNITY TUTORIAL | SCRIPTING | Awake() and Start()

Awake()

• Awake() is called first even if the script component is not enabled
• Awake() is best used for setting up any references between scripts and initialization

Start()

• Start() is called after Awake() immediately before the first Update()
• Start() is called only if the script component is enabled
• Start() is used for anything we need to occur
• Start() is only called once in the life time of a script on a gameObject
• It is impossible to repeat Start()
• all of the codes in Start() are called on the first frame that the script is active

Example)

• Awake()
  • set ammo for “enemy” gameObject
• Start()
  • allow “enemy” to shot
