StateMachineBehaviour is a component that can be added to a state machine state. It's the base class every script on a state derives from.
By default the Animator does instantiate a new instance of each behaviour define in the controller. The class attribute SharedBetweenAnimatorsAttribute control how behaviours are instantiated.
StateMachineBehaviour has some predefined messages:
OnStateEnter, OnStateExit, OnStateIK, OnStateMove, OnStateUpdate.
using UnityEngine;
public class AttackBehaviour : StateMachineBehaviour { public GameObject particle; public float radius; public float power; protected GameObject clone; override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { clone = Instantiate(particle, animator.rootPosition, Quaternion.identity) as GameObject; Rigidbody rb = clone.GetComponent<Rigidbody>(); rb.AddExplosionForce(power, animator.rootPosition, radius, 3.0f); } override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { Destroy(clone); } override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { Debug.Log("On Attack Update "); } override public void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { Debug.Log("On Attack Move "); } override public void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) { Debug.Log("On Attack IK "); } }
| OnStateMachineEnter | Called on the first Update frame when making a transition to a StateMachine. This is not called when making a transition into a StateMachine sub-state. |
| OnStateMachineExit | Called on the last Update frame when making a transition out of a StateMachine. This is not called when making a transition into a StateMachine sub-state. |
| OnStateEnter | Called on the first Update frame when a statemachine evaluate this state. |
| OnStateExit | Called on the last update frame when a statemachine evaluate this state. |
| OnStateIK | Called right after MonoBehaviour.OnAnimatorIK. |
| OnStateMove | Called right after MonoBehaviour.OnAnimatorMove. |
| OnStateUpdate | Called at each Update frame except for the first and last frame. |
| hideFlags | Should the object be hidden, saved with the scene or modifiable by the user? |
| name | El nombre del objeto. |
| GetInstanceID | Returns the instance id of the object. |
| ToString | Devuelve el nombre del objeto. |
| Destroy | Elimina un gameobject, componente o asset. |
| DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. |
| DontDestroyOnLoad | Makes the object target not be destroyed automatically when loading a new scene. |
| FindObjectOfType | Devuelve el primer objeto activo cargado de tipo type. |
| FindObjectsOfType | Devuelve una lista de todos los objetos activos cargados de tipo type. |
| Instantiate | Devuelve el nombre del objeto. |
| CreateInstance | Creates an instance of a scriptable object. |
| bool | ¿Existe el objeto? |
| operator != | Compares if two objects refer to a different object. |
| operator == | Compares two object references to see if they refer to the same object. |
