Types

type DefaultStateMachine

type DefaultStateMachine[E any] struct {
	Owner         E        //状态机拥有者
	CurrentState  State[E] //当前状态
	PreviousState State[E] //之前状态
	GlobalState   State[E] //全局状态，每个State Update都会调用
}

DefaultStateMachine 默认状态机管理器 另外可实现堆栈状态机，可依次返回之前状态 ，如菜单列表

func (*DefaultStateMachine[E]) ChangeState

func (sm *DefaultStateMachine[E]) ChangeState(newState State[E])

func (*DefaultStateMachine[E]) HandleMessage

func (sm *DefaultStateMachine[E]) HandleMessage(message interface{}) bool

func (*DefaultStateMachine[E]) IsInState

func (sm *DefaultStateMachine[E]) IsInState(state State[E]) bool

func (*DefaultStateMachine[E]) RevertToPreviousState

func (sm *DefaultStateMachine[E]) RevertToPreviousState() bool

func (*DefaultStateMachine[E]) SetInitialState

func (sm *DefaultStateMachine[E]) SetInitialState(state State[E])

func (*DefaultStateMachine[E]) Update

func (sm *DefaultStateMachine[E]) Update()

Update 更新当前或全局状态

type EmptyState

type EmptyState[E any] struct {
}

EmptyState 空状态，默认实现所有方法

func (*EmptyState[E]) Enter

func (state *EmptyState[E]) Enter(entity E)

func (*EmptyState[E]) Exit

func (state *EmptyState[E]) Exit(entity E)

func (*EmptyState[E]) HandleMessage

func (state *EmptyState[E]) HandleMessage(entity E, message interface{}) bool

func (*EmptyState[E]) Update

func (state *EmptyState[E]) Update(entity E)

type State

type State[E any] interface {
	Enter(entity E)                                   //状态进入
	Update(entity E)                                  //正常定时监测更新
	Exit(entity E)                                    //状态退出
	HandleMessage(entity E, message interface{}) bool //向当前的状态或全局状态发送消息
}

State 状态

type StateMachine

type StateMachine[E any] interface {
	Update()                                //定时监测更新状态
	ChangeState(state State[E])             //执行状态转移
	RevertToPreviousState() bool            //返回到之前状态 true 成功
	SetInitialState(state State[E])         //设置初始状态
	IsInState(state State[E]) bool          //当前状态是否在给定的状态
	HandleMessage(message interface{}) bool //处理消息
}

StateMachine 处理实体状态移动或者处理接收到的消息
