Cocos2D-x game development 21: ScheduleUpdate and ScheduleOne usage

Today I learned the Coco2D-x timer, Cocos2D for us to encapsulate the timer function, we only need to use the place directly:

Schedule can be used directly, that is, it is called in the init () function by default: this-> scheduleupdate (); and Update () can be redefined.

You can also call this-.> schedule (schedule_selector (HelloWorld: MYUpdate), 3.0f) and then implement the MYUpdate function to call the MYUpdate function every 3.0f.

We can also make a function run only once at a specific time: this-> scheduleOnce (schedule_selector (HelloWorld: MYUpdate), 3.0f );

This-> scheduleUpdate (); this-> schedule (schedule_selector (HelloWorld: updateForMe), 2.0f); this-> scheduleOnce (schedule_selector (HelloWorld: updateForMe), 2.0f );
