Learn Basic JavaScript by Building a Role Playing Game - Step 111

Tell us what’s happening:

Hi There!!! I’ve been learning from the previous JavaScript update, i lost my progress but the new update is better and i’m learning better than before but in this challenge i came across this issue.

Your code so far

This code works

function fightSlime() {
  fighting = 0;
  goFight();
}

But this one doesnt. Isn’t the one below supposed to work! cause the one above doesnt mention the variable(monster) where slime is stored. Can you please explain this ? :pray:

let xp = 0;
let health = 100;
let gold = 50;
let currentWeapon = 0;
let fighting;
let monsterHealth;
let inventory = ["stick"];

const button1 = document.querySelector('#button1');
const button2 = document.querySelector("#button2");
const button3 = document.querySelector("#button3");
const text = document.querySelector("#text");
const xpText = document.querySelector("#xpText");
const healthText = document.querySelector("#healthText");
const goldText = document.querySelector("#goldText");
const monsterStats = document.querySelector("#monsterStats");
const monsterName = document.querySelector("#monsterName");
const monsterHealthText = document.querySelector("#monsterHealth");
const weapons = [
  { name: 'stick', power: 5 },
  { name: 'dagger', power: 30 },
  { name: 'claw hammer', power: 50 },
  { name: 'sword', power: 100 }
];
const monsters = [
  {
    name: "slime",
    level: 2,
    health: 15
  },
  {
    name: "fanged beast",
    level: 8,
    health: 60
  },
  {
    name: "dragon",
    level: 20,
    health: 300
  }
]
const locations = [
  {
    name: "town square",
    "button text": ["Go to store", "Go to cave", "Fight dragon"],
    "button functions": [goStore, goCave, fightDragon],
    text: "You are in the town square. You see a sign that says \"Store\"."
  },
  {
    name: "store",
    "button text": ["Buy 10 health (10 gold)", "Buy weapon (30 gold)", "Go to town square"],
    "button functions": [buyHealth, buyWeapon, goTown],
    text: "You enter the store."
  },
  {
    name: "cave",
    "button text": ["Fight slime", "Fight fanged beast", "Go to town square"],
    "button functions": [fightSlime, fightBeast, goTown],
    text: "You enter the cave. You see some monsters."
  }
];

// initialize buttons
button1.onclick = goStore;
button2.onclick = goCave;
button3.onclick = fightDragon;

function update(location) {
  button1.innerText = location["button text"][0];
  button2.innerText = location["button text"][1];
  button3.innerText = location["button text"][2];
  button1.onclick = location["button functions"][0];
  button2.onclick = location["button functions"][1];
  button3.onclick = location["button functions"][2];
  text.innerText = location.text;
}

function goTown() {
  update(locations[0]);
}

function goStore() {
  update(locations[1]);
}

function goCave() {
  update(locations[2]);
}

function buyHealth() {
  if (gold >= 10) {
    gold -= 10;
    health += 10;
    goldText.innerText = gold;
    healthText.innerText = health;
  } else {
    text.innerText = "You do not have enough gold to buy health.";
  }
}

function buyWeapon() {
  if (currentWeapon < weapons.length - 1) {
    if (gold >= 30) {
      gold -= 30;
      currentWeapon++;
      goldText.innerText = gold;
      let newWeapon = weapons[currentWeapon].name;
      text.innerText = "You now have a " + newWeapon + ".";
      inventory.push(newWeapon);
      text.innerText += " In your inventory you have: " + inventory;
    } else {
      text.innerText = "You do not have enough gold to buy a weapon.";
    }
  } else {
    text.innerText = "You already have the most powerful weapon!";
    button2.innerText = "Sell weapon for 15 gold";
    button2.onclick = sellWeapon;
  }
}

function sellWeapon() {
  if (inventory.length > 1) {
    gold += 15;
    goldText.innerText = gold;
    let currentWeapon = inventory.shift();
    text.innerText = "You sold a " + currentWeapon + ".";
    text.innerText += " In your inventory you have: " + inventory;
  } else {
    text.innerText = "Don't sell your only weapon!";
  }
}

function fightSlime() {
  fighting = monsters[0];
  goFight();
}

function fightBeast() {

}

function fightDragon() {
  console.log("Fighting dragon.");
}

function goFight() {

}

Generally that depends how the rest - mainly the goFight function is or will be written. As here fighting is expected to be integer, it can be assumed that in goFight function that information will be used with the monsters array.

I’m sorry for the late reply.
I didn’t understand that !
Did you mean that, the computer assumes that the 0 in fighting = 0; is the index of the object in the monsters array ?

Edit : I think i understand it now in step 116. The 0 acts as a placeholder for the fighting in function goFight. Is that right?

Hello!

You were right with your first guess: 0 stands for the index of the monster object in the monsters array.

0 = slime, 1 = fanged beast , 2 = dragon

Be aware what you see in the courses often isn’t the actual code, it’s a simulation. For example introducing just a part of a function and adding its code blocks step by step. This wouldn’t work with active code. For students that already have a wider understanding of the language such code doesn’t make sense sometimes.
