State – uNode

The State node is node to be used to make State Machine.

The State node can have one or many events and nodes.

to add a events double click the state to edit the State Node and right click on canvas > Add Event > and select available events

Available events:

On Enter called on state enter.
On Exit called on state exit.
Update is called every frame, if the MonoBehaviour is enabled and if state is running.
FixedUpdate is called every fixed framerate frame, if the MonoBehaviour is enabled and if state is running.
LateUpdate is called every frame, if the Behaviour is enabled and if state is running.
OnApplicationFocus called when the player gets or loses focus and state is running.
OnApplicationPause called when the player pauses and if state is running.
OnApplicationQuit called before the application is quit and if state is running.
OnBecameInvisible is called when the renderer is no longer visible by any camera and if state is running.
OnBecameVisibleis called when the renderer became visible by any camera and if state is running.
OnCollisionEnter is called when this collider/rigidbody has begun touching another rigidbody/collider and if state is running.
OnCollisionEnter2D called when an incoming collider makes contact with this object’s collider (2D physics only) and if state is running.
OnCollisionExitis called when this collider/rigidbody has stopped touching another rigidbody/collider and if state is running.
OnCollisionExit2D Sent when a collider on another object stops touching this object’s collider (2D physics only) and if state is running.
OnCollisionStay is called once per frame for every collider/rigidbody that is touching rigidbody/collider and if state is running.
OnCollisionStay2D called each frame where a collider on another object is touching this object’s collider (2D physics only) and if state is running.
OnDestroy is called when the MonoBehaviour will be destroyed and if state is running.
OnDisable is called when the behaviour becomes disabled () or inactive and if state is running.
OnEnable is called when the object becomes enabled and active and if state is running.
OnGUI is called for rendering and handling GUI events and if state is running.
OnMouseDown is called when the user has pressed the mouse button while over the GUIElement or Collider and if state is running.
OnMouseDrag is called when the user has clicked on a GUIElement or Collider and is still holding down the mouse and if state is running.
OnMouseEnter Called when the mouse enters the GUIElement or Collider and if state is running.
OnMouseExit Called when the mouse is not any longer over the GUIElement or Collider and if state is running.
OnMouseOver Called every frame while the mouse is over the GUIElement or Collider and if state is running.
OnMouseUp is called when the user has released the mouse button and if state is running.
OnMouseUpAsButton is only called when the mouse is released over the same GUIElement or Collider as it was pressed and if state is running.
OnPostRender is called after a camera finished rendering the scene and if state is running.
OnPreCull is called before a camera culls the scene and if state is running.
OnPreRender is called before a camera starts rendering the scene and if state is running.
OnRenderObject is called after camera has rendered the scene and if state is running.
OnTriggerEnter is called when the Collider other enters the trigger and if state is running.
OnTriggerEnter2D Sent when another object enters a trigger collider attached to this object (2D physics only) and if state is running.
OnTriggerExit is called when the Collider other has stopped touching the trigger and if state is running.
OnTriggerExit2D Sent when another object leaves a trigger collider attached to this object (2D physics only) and if state is running.
OnTriggerStay is called once per frame for every Collider other that is touching the trigger and if state is running.
OnTriggerStay2D Sent each frame where another object is within a trigger collider attached to this object (2D physics only) and if state is running.
OnWillRenderObject is called once for each camera if the object is visible and if state is running.

The State node have a transition, the transition is an event and if it triggered the state will change to another state.
You can add transition event by right click on node > Add New Transition > and select available transition.

Available transitions:

Condition finish when the condition is true.
OnApplicationFocus finish when the player gets or loses focus.
OnApplicationPause finish when the player pauses.
OnApplicationQuit finish before the application is quit.
OnBecameInvisible finish when the renderer is no longer visible by any camera.
OnBecameVisible finish when the renderer became visible by any camera.
OnCollisionEnter finish when this collider/rigidbody has begun touching another rigidbody/collider.
OnCollisionEnter2D finish when an incoming collider makes contact with this object’s collider (2D physics only).
OnCollisionExit finish when this collider/rigidbody has stopped touching another rigidbody/collider.
OnCollisionExit2D finish when a collider on another object stops touching this object’s collider (2D physics only).
OnCollisionStay finish when collider/rigidbody that is touching rigidbody/collider and if state is running.
OnCollisionStay2D finish whena collider on another object is touching this object’s collider (2D physics only).
OnDestroy finish when the MonoBehaviour will be destroyed.
OnDisable finish when the behaviour becomes disabled () or inactive.
OnEnable finish when the object becomes enabled and active.
OnMouseDown finish when the user has pressed the mouse button while over the GUIElement or Collider.
OnMouseDrag finish when the user has clicked on a GUIElement or Collider and is still holding down the mouse.
OnMouseEnter finish when the mouse enters the GUIElement or Collider.
OnMouseExit finish when the mouse is not any longer over the GUIElement or Collider.
OnMouseOver finish every frame while the mouse is over the GUIElement or Collider.
OnMouseUp finish when the user has released the mouse button.
OnMouseUpAsButton finish when the mouse is released over the same GUIElement or Collider as it was pressed.
OnTimerElapsed finish when the given times is reach.
OnTriggerEnter finish when the Collider other enters the trigger.
OnTriggerEnter2D finish when another object enters a trigger collider attached to this object (2D physics only).
OnTriggerExit finish when the Collider other has stopped touching the trigger.
OnTriggerExit2D finish when another object leaves a trigger collider attached to this object (2D physics only).
OnTriggerStay finish once per frame for every Collider other that is touching the trigger.
