Hangman Game With Javascript

Hello everyone. Welcome to today’s tutorial. In today’s tutorial, we will learn how to create the hangman game. To build this game, we need HTML, CSS and vanilla javascript.

Let us see how this game works. The hangman game provides the user with three options to choose from. These options are – ‘Fruits’, ‘Animals’ and ‘Countries’. Once the user selects the option, the computer chooses a word from the corresponding category.

Now, the user has to guess the chosen word using the letter buttons provided on the screen. The user can make six wrong attempts before he loses the game.

If the user guesses the word, we display a winning message on the screen. If not, we display a lost message. Along with this message, we also provide the user with the solution and a button to start ‘New Game’.

This project is suitable for javascript intermediates. If you are looking for more projects to improve your javascript skills, you should check out this playlist here. This playlist from my youtube channel consists of 80+ javascript projects. Each of these projects comes with a free downloadable source code.

Project Folder Structure:

Let us take a look at the project folder structure. We create a project folder called – ‘ Hangman Game’. Inside this folder, we have three files- index.html, style.css and script.js. These are the HTML document, the stylesheet and the script file respectively.

HTML:

We begin with the HTML code. The HTML creates the elements necessary to build the structure of our project. Now copy the code below and paste it into your HTML document.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Hangman</title>
    <!-- Google Fonts -->
    <link
      href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;600&display=swap"
      rel="stylesheet"
    />
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="container">
      <div id="options-container"></div>
      <div id="letter-container" class="letter-container hide"></div>
      <div id="user-input-section"></div>
      <canvas id="canvas"></canvas>
      <div id="new-game-container" class="new-game-popup hide">
        <div id="result-text"></div>
        <button id="new-game-button">New Game</button>
      </div>
    </div>
    <!-- Script -->
    <script src="script.js"></script>
  </body>
</html>

CSS:

Next, we style these elements to give them a modern and sleek look. To do this we use CSS. First copy the code provided to you below and paste it into your stylesheet.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  font-family: "Poppins", sans-serif;

}
#new-game-button {
  font-size: 1.25em;
  padding: 0.5em 1em;
  background-color: #f4c531;
  border: 3px solid #000000;

}
.win-msg {
  color: #39d78d;

}

Javascript:

Lastly, we need to add functionality to this project to make it work. For this we use Javascript. Now copy the code below and paste it into your script file.

//Initial References
const letterContainer = document.getElementById("letter-container");
const optionsContainer = document.getElementById("options-container");
const userInputSection = document.getElementById("user-input-section");
const newGameContainer = document.getElementById("new-game-container");
const newGameButton = document.getElementById("new-game-button");
const canvas = document.getElementById("canvas");
const resultText = document.getElementById("result-text");

//Options values for buttons
let options = {
  fruits: [
    "Apple",
    "Blueberry",
    "Mandarin",
    "Pineapple",
    "Pomegranate",
    "Watermelon",
  ],
  animals: ["Hedgehog", "Rhinoceros", "Squirrel", "Panther", "Walrus", "Zebra"],
  countries: [
    "India",
    "Hungary",
    "Kyrgyzstan",
    "Switzerland",
    "Zimbabwe",
    "Dominica",
  ],
};

//count
let winCount = 0;
let count = 0;

let chosenWord = "";

//Display option buttons
const displayOptions = () => {
  optionsContainer.innerHTML += `<h3>Please Select An Option</h3>`;
  let buttonCon = document.createElement("div");
  for (let value in options) {
    buttonCon.innerHTML += `<button class="options" onclick="generateWord('${value}')">${value}</button>`;
  }
  optionsContainer.appendChild(buttonCon);
};

//Block all the Buttons
const blocker = () => {
  let optionsButtons = document.querySelectorAll(".options");
  let letterButtons = document.querySelectorAll(".letters");
  //disable all options
  optionsButtons.forEach((button) => {
    button.disabled = true;
  });

  //disable all letters
  letterButtons.forEach((button) => {
    button.disabled.true;
  });
  newGameContainer.classList.remove("hide");
};

//Word Generator
const generateWord = (optionValue) => {
  let optionsButtons = document.querySelectorAll(".options");
  //If optionValur matches the button innerText then highlight the button
  optionsButtons.forEach((button) => {
    if (button.innerText.toLowerCase() === optionValue) {
      button.classList.add("active");
    }
    button.disabled = true;
  });

  //initially hide letters, clear previous word
  letterContainer.classList.remove("hide");
  userInputSection.innerText = "";

  let optionArray = options[optionValue];
  //choose random word
  chosenWord = optionArray[Math.floor(Math.random() * optionArray.length)];
  chosenWord = chosenWord.toUpperCase();

  //replace every letter with span containing dash
  let displayItem = chosenWord.replace(/./g, '<span class="dashes">_</span>');

  //Display each element as span
  userInputSection.innerHTML = displayItem;
};

//Initial Function (Called when page loads/user presses new game)
const initializer = () => {
  winCount = 0;
  count = 0;

  //Initially erase all content and hide letteres and new game button
  userInputSection.innerHTML = "";
  optionsContainer.innerHTML = "";
  letterContainer.classList.add("hide");
  newGameContainer.classList.add("hide");
  letterContainer.innerHTML = "";

  //For creating letter buttons
  for (let i = 65; i < 91; i++) {
    let button = document.createElement("button");
    button.classList.add("letters");
    //Number to ASCII[A-Z]
    button.innerText = String.fromCharCode(i);
    //character button click
    button.addEventListener("click", () => {
      let charArray = chosenWord.split("");
      let dashes = document.getElementsByClassName("dashes");
      //if array contains clciked value replace the matched dash with letter else dram on canvas
      if (charArray.includes(button.innerText)) {
        charArray.forEach((char, index) => {
          //if character in array is same as clicked button
          if (char === button.innerText) {
            //replace dash with letter
            dashes[index].innerText = char;
            //increment counter
            winCount += 1;
            //if winCount equals word lenfth
            if (winCount == charArray.length) {
              resultText.innerHTML = `<h2 class='win-msg'>You Win!!</h2><p>The word was <span>${chosenWord}</span></p>`;
              //block all buttons
              blocker();
            }
          }
        });
      } else {
        //lose count
        count += 1;
        //for drawing man
        drawMan(count);
        //Count==6 because head,body,left arm, right arm,left leg,right leg
        if (count == 6) {
          resultText.innerHTML = `<h2 class='lose-msg'>You Lose!!</h2><p>The word was <span>${chosenWord}</span></p>`;
          blocker();
        }
      }
      //disable clicked button
      button.disabled = true;
    });
    letterContainer.append(button);
  }

  displayOptions();
  //Call to canvasCreator (for clearing previous canvas and creating initial canvas)
  let { initialDrawing } = canvasCreator();
  //initialDrawing would draw the frame
  initialDrawing();
};

//Canvas
const canvasCreator = () => {
  let context = canvas.getContext("2d");
  context.beginPath();
  context.strokeStyle = "#000";
  context.lineWidth = 2;

  //For drawing lines
  const drawLine = (fromX, fromY, toX, toY) => {
    context.moveTo(fromX, fromY);
    context.lineTo(toX, toY);
    context.stroke();
  };

  const head = () => {
    context.beginPath();
    context.arc(70, 30, 10, 0, Math.PI * 2, true);
    context.stroke();
  };

  const body = () => {
    drawLine(70, 40, 70, 80);
  };

  const leftArm = () => {
    drawLine(70, 50, 50, 70);
  };

  const rightArm = () => {
    drawLine(70, 50, 90, 70);
  };

  const leftLeg = () => {
    drawLine(70, 80, 50, 110);
  };

  const rightLeg = () => {
    drawLine(70, 80, 90, 110);
  };

  //initial frame
  const initialDrawing = () => {
    //clear canvas
    context.clearRect(0, 0, context.canvas.width, context.canvas.height);
    //bottom line
    drawLine(10, 130, 130, 130);
    //left line
    drawLine(10, 10, 10, 131);
    //top line
    drawLine(10, 10, 70, 10);
    //small top line
    drawLine(70, 10, 70, 20);
  };

  return { initialDrawing, head, body, leftArm, rightArm, leftLeg, rightLeg };
};

//draw the man
const drawMan = (count) => {
  let { head, body, leftArm, rightArm, leftLeg, rightLeg } = canvasCreator();
  switch (count) {
    case 1:
      head();
      break;
    case 2:
      body();
      break;
    case 3:
      leftArm();
      break;
    case 4:
      rightArm();
      break;
    case 5:
      leftLeg();
      break;
    case 6:
      rightLeg();
      break;
    default:
      break;
  }
};

//New Game
newGameButton.addEventListener("click", initializer);
window.onload = initializer;
