How To Implement Action Sequence In Game Loop

Action Lists

class Action {
    public:
        virtual bool isFinished() = 0;
        virtual void update(uint64_t dt) = 0; 
        virtual ~Action() {
        }
};

class NothingAction : public Action {
    public:
        uint64_t m_currentTime = 0;
        bool m_finish = false;
        uint64_t m_nothingTime = 0;
        NothingAction(uint64_t idleTime) : m_nothingTime(idleTime) {
        }
        virtual ~NothingAction() {
        } 
        virtual bool isFinished() {
            return m_finish; 
        }
        virtual void update(uint64_t dt) {
            m_currentTime += dt;
            printf("idle\n");
            if(m_currentTime >= m_nothingTime) {
                m_finish = true;
                printf("nothing finish\n");
            }
        }

};
