Recently I am trying to develop a Cocos2d-x game using the MVC model. How should the timer (such as the countdown before starting the game) be placed? The countdown int variable must be put into the Model, but where to modify this value? Should we process it in the Model and send an event to notify the Controller after updating the variables? Or should we schedule and modify the variables in the Controller?

Timer is a logic program and should be written in
Controller.
