这是自己写的一个状态机在UI界面中使用的样例

function PXUITreaChest:addStateMachine()

    self.fsm_ = {}
    cc(self.fsm_)
        :addComponent("components.behavior.StateMachine")
        :exportMethods()
    self.fsm_:setupState({
        --defer 翻译:延迟 状态机初始状态为none 如果这个为false 则状态自动none->normal 反之需setupState结束后 doEvent("normal")
        --{name = "startup",   from = "none",  to = "normal"}, --下面这句可以这么理解
        initial = {state = "Normal", event = "Startup", defer = false},
        events = {
            --{name = "ToGetData", from = {"Normal", "OpenBox"}, to = "GetData"},
            {name = "ToGetData", from = "Normal", to = "GetData"},
            {name = "ToPanelBase", from = {"GetData", "OpenInfo", "BuyBox", "OpenBox"}, to = "PanelBase"},
            {name = "ToOpenInfo",  from = "PanelBase", to = "OpenInfo"},
            {name = "ToBuyBox",  from = "PanelBase", to = "BuyBox"},
            {name = "ToOpenBox",   from = "BuyBox",  to = "OpenBox"},
            -- {name = "release", from = "pressed", to = "normal"},
        },
        callbacks = {
    
            onenterNormal = handler(self, self.InitAll),    --初始化一切
            onenterGetData = handler(self, self.initPanelData),--初始化数据
            onenterPanelBase = handler(self, self.initPanelBase),--保持界面一致
            onenterOpenInfo = handler(self, self.openInfo),--查看信息
            onenterBuyBox = handler(self, self.buyBox),--购买宝箱界面
            onenterOpenBox = handler(self, self.openBox),--打开宝箱界面
            
        },
        terminal = "normal" --与to的状态做比较 相关函数 self.fsm_:isFinishedState()是否最终状态
    })

end

function PXUITreaChest:SetState(_szState, ...)
    assert(self.fsm_, "状态机不存在")
    if self.fsm_:canDoEvent(_szState) then
        self.fsm_:doEvent(_szState, ...)
    else
        printf("不能跳转状态, 从状态: %s 跳转到 %s", self.fsm_:getState(), _szState)
    end
end
