Begginer here.

It looks like you want to create an object that can invoke an action to "drink" a beer. The following is the newer class syntax (ES6) which is not widely supported in older browsers, but worth a study.

class Player {
    constructor(){
        this.isDrunk = false;
    }

    useBeer(){
        this.isDrunk = true;
    }

    isDrunk(){
        return this.isDrunk;
    }
}

var player = new Player();
player.useBeer();
console.log(player.isDrunk()); // true

You can set the value of isDrunk either using switch or if statement, anything of your choice. But before that kindly have a look at the syntax or way of creating objects.

  var player = {isDrunk:false, hadBeer:false}
  if (player.hadBeer) {
    player.isDrunk = true;
  } else {
    player.isDrunk = false;
  }

To specifically answer your question you would just do something like player.isDrunk = true

So you could have something like 

var player = {
  leftHanded: false,
  rightHanded: true,
  isDrunk: false
 };

And then

  function drinkBeer(player) {
      player.isDrunk = true;
 }

Then you can pass your players to your drinkBeer function as needed. Alternatively you can put the function inside the player object if you want each individual player to have a drinkBeer() function that they can use to change their own isDrunk property by calling player.drinkBeer()

That would look like this:

var player = {
  leftHanded: false,
  rightHanded: true,
  isDrunk: false,
  drinkBeer: function() {
        isDrunk = true;
     }
 };

You should google your question before you ask it because documentation for JavaScript objects is everywhere... But...

var player = {
  myFirstValue: true,
  mySecondValue: false
};

player.myFirstValue = false;
