Tap and timing game code mechanics (typescript)

I am building a tap on-time game I need mechanics for it

  1. use some sort of timer to decide if the player has touched what you want in the time they needed to touch it in.

  2. repeat

  3. perhaps there are many objects for them to touch all at once or very quickly. Use a manager class to track each object.

  4. Perhaps there is physics involved?

yes, I am trying to apply different sprites according to red-yellow-green color when tap correctly the sprites will appear I need any kind of reference. you know I am quite new to the coding of javascript

Please review our getting started guide. https://docs.cocos2d-x.org/creator/manual/en/getting-started/

examples-cases-master has the solutions !!!

const {ccclass, property} = cc._decorator;

@ccclass
export default class xmover extends cc.Component {

@property 

speed : number = 10;

update (dt)
{
this.node.x -= this.speed * dt;

if (this.node.x < -2*(this.node.width*2) - this.node.width/2)
  {
    this.node.setPosition((this.node.parent.width/2 + this.node.width/2.5), 0,);
   }

}

}
