How to Get Past Level Four? about warriorjs HOT 10 CLOSED

To get past level four is crucial that your warrior rests, just like in level three. However, now you must check that you are not being attacked before resting. To do so, you can store your warrior's health in a Player's instance property at the end of each turn, and if your warrior is injured but the health at the end of past turn is greater than its current health (which means he's under attack), you should walk/attack instead of rest.

I've been trying to do that, but I can't figure out what the code for it would be.

I could give you a few pointers, but not the complete solution. After all, this game is intended to learn, and you won't learn anything if I do.

class Player {
  constructor() {
    this._health = 20;
  }

  playTurn(warrior) {
    // TODO: Add missing condition
    if () {
      warrior.rest();
    } else {
      if (warrior.feel().isEnemy()) {
        warrior.attack();
      } else {
        warrior.walk();
      }
    }

    // TODO: Update this._health with warrior.health
  }

  isInjured(warrior) {
    // TODO: Return false if warrior health is less than 20
  }

  isUnderAttack(warrior) {
    // TODO: Compare this._health with warrior.health()
  }
}

You can call the newly defined methods isInjured and isUnderAttack (and any other method you create in the future) from the playTurn method like this:

this.isInjured(warrior)

Good luck!

Thanks!

My JS ain't that good, although I'm pretty sure I'm on the right track. I've added my code to this gist so as not to spoil for anyone. Would appreciate some guidance via a tip in the gist (do gist comments send notifications?)

@pawel2105 I just left a comment in your gist. Good luck!

@olistic Hi, really enjoy the game however struggling with the above.
Everything goes okay however my warrior does not rest enough to beat the final sludge, he will rest for one turn then walk the other!

Would appreciate some guidance if possible? It feels like such a small thing.

Hi @williamgurney! I left a comment in your gist, cheers!

class Player {
  
  constructor() {
    this._health = 20;
  }

  playTurn(warrior) {
    // TODO: Add missing condition
    warrior.think("Am I under attack? "+this.isUnderAttack(warrior.health()));
    if (
      this.isInjured(warrior.health()) && 
      !this.isUnderAttack(warrior.health())) {
      warrior.rest();
    } else if(!warrior.feel().isEmpty()) {
      warrior.attack();
    } else {
      warrior.walk();
    }
    
    this._health = warrior.health(); 
  }

  isInjured(health) {
    if(health < 20){
      return true;
    }
    return false;
    // TODO: Return true if warrior health is less than 20
  }

  isUnderAttack(health) {
    if(health < this._health){
      return true;
    }
    return false;
    // TODO: Compare this._health with warrior.health()
  }

}

@olistic Based on your example this implementation works. I tried creating a method chained IsEnemy() to feel(), but doing a !warrior.feel().isEmpty() is enough

No es muy creativa mi respuesta, pero es otra alternativa:

class Player {

playTurn(warrior) {

if (this.health==null){this.health=0;} 

if (this.health==0) {warrior.walk()}
else if(this.health<=5){warrior.attack()}
else if(this.health<=6){warrior.walk()}
else if(this.health<=10){warrior.attack()}
else if(this.health<=20){warrior.rest()}
else if(this.health<=22){warrior.walk()}
else if(this.health<=30){warrior.attack()}
else if(this.health<=35){warrior.walk()}

this.health = this.health+1
warrior.think(this.health);
}
}
