ZenCoder Lifecycle Methods

ZenCoder supports Unity-style lifecycle methods. You can add them by typing, via IntelliSense, or from the Lifecycle panel.
Execution matches Unity semantics: editor-safe callbacks can run in Edit Mode; all runtime callbacks run in Play Mode.

Signatures below match ZenCoder’s snippets (e.g., Update(float deltaTime), FixedUpdate(float fixedDeltaTime)).

Initialization

Method	Edit Mode	Play Mode	Description
`Awake()`	✅ Yes	✅ Yes	Called when the script instance is loaded.
`OnEnable()`	✅ Yes	✅ Yes	Called when the object becomes enabled and active.
`OnDisable()`	✅ Yes	✅ Yes	Called when the behaviour becomes disabled.
`Start()`	✅ Yes	✅ Yes	Called before the first frame update.
`Reset()`	✅ Yes	✅ Yes	Resets public variables to default values.
`OnDestroy()`	✅ Yes	✅ Yes	Called when the object is destroyed.
`OnValidate()`	✅ Yes	❌ No	Called when script properties change in the Inspector.

Game Loop

Rendering

Method	Edit Mode	Play Mode	Description
`OnPreCull()`	❌ No	✅ Yes	Called before the camera culls the scene.
`OnPreRender()`	❌ No	✅ Yes	Called before the camera starts rendering.
`OnPostRender()`	❌ No	✅ Yes	Called after the camera has finished rendering.

Notes

Only methods present in your ZenCoder script are registered and executed.
Edit Mode execution is limited to Unity’s editor-safe callbacks.
Lifecycle methods can be added by typing, via IntelliSense, or through the Lifecycle Panel — ZenCoder automatically detects and updates them in real time.
