UnityEngine.MonoBehaviour
UnityEngine.MonoBehaviour
UnityEngine.MonoBehaviour is the base class from which every Unity script derives. It allows scripts to be attached to GameObjects and provides core Unity event methods for controlling behavior in the game engine.
Key Features
- Attach scripts to GameObjects in the Unity Editor.
- Provides event methods such as
Start(),Update(),FixedUpdate(),OnDestroy(), and more. - Supports coroutines for running code over several frames.
- Enables access to Unity's component system (e.g.,
GetComponent<T>()).
Commonly Used Methods
- Awake()
- Called when the script instance is being loaded.
- Start()
- Called before the first frame update if the script is enabled.
- Update()
- Called once per frame.
- FixedUpdate()
- Called at a fixed interval, used for physics updates.
- LateUpdate()
- Called after all Update functions have been called.
- OnEnable()
- Called when the object becomes enabled and active.
- OnDisable()
- Called when the object becomes disabled.
- OnDestroy()
- Called when the MonoBehaviour will be destroyed.
- StartCoroutine(IEnumerator routine)
- Starts a coroutine.
- StopCoroutine(IEnumerator routine)
- Stops a specific coroutine.
- StopAllCoroutines()
- Stops all coroutines running on this behaviour.
- Invoke(string methodName, float time)
- Invokes a method after a delay.
- CancelInvoke(string methodName)
- Cancels all Invoke calls with the given method name.
- IsInvoking(string methodName)
- Returns true if the method is invoked.
Commonly Used Properties
- enabled
- Enables/disables the behaviour (bool).
- isActiveAndEnabled
- Returns true if the behaviour is enabled and the GameObject is active (bool).
- gameObject
- The GameObject this component is attached to.
- transform
- The Transform attached to this GameObject.
- tag
- The tag of this GameObject.
- name
- The name of this GameObject.
- hideFlags
- Flags to control object visibility in the editor.
