Creating an Engaging Number Guessing Game Using Vue 3 and JavaScript
Written on
Chapter 1: Introduction to Vue 3
Vue 3 is the latest iteration of the popular Vue JavaScript framework, designed for building user-friendly front-end applications. In this guide, we will explore the steps to create an interactive number guessing game using Vue 3 and JavaScript.
Section 1.1: Setting Up the Project
To begin, we need to set up our Vue project. This can be done effortlessly using the Vue CLI. To install it, execute the following command:
npm install -g @vue/cli
Alternatively, if you're using Yarn, run:
yarn global add @vue/cli
Once the installation is complete, create your project by running:
vue create number-guessing-game
Select the default options to get started.
Subsection 1.1.1: Designing the Game Interface
Now that your project is set up, we can construct the number guessing game. Below is the essential code snippet to create the game interface:
<template>
<div v-if="started">
<form @submit.prevent="submit">
<div>
<label>Your Guess</label>
<input v-model.number="answer" />
</div>
<button type="submit">Check</button>
</form>
<p>{{ status }}</p>
</div>
<div v-else>
<button type="button" @click="start">Start</button>
<p>{{ status }}</p>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {
rightAnswer: undefined,
answer: 0,
status: "",
started: false,
};
},
computed: {
formValid() {
return +this.answer >= 0;},
},
methods: {
start() {
this.rightAnswer = Math.ceil(Math.random() * 10);
console.log(this.rightAnswer);
this.started = true;
},
submit() {
if (!this.formValid) {
return;}
const { answer, rightAnswer } = this;
if (answer === rightAnswer) {
this.status = "You guessed it right!";
this.started = false;
} else if (answer < rightAnswer) {
this.status = "Your guess is too low.";} else {
this.status = "Your guess is too high.";}
},
},
};
</script>
In this code:
- We start by creating a form that is displayed when the game is active, which is indicated by the started variable being true.
- The form captures the player's guess through an input field, where we bind the entered value to the answer property using v-model.
- Upon submitting the form, we call the submit method to evaluate the guess.
Section 1.2: Game Logic Implementation
The game logic involves generating a random number and validating the player's input. The start method initiates the game by assigning a random number to rightAnswer. The submit method compares the player's guess with the correct answer and provides feedback based on the comparison.
