Creating a Fun Whack-a-Mole Game Using Vue 3 and JavaScript
Written on
Chapter 1: Introduction to Vue 3
Vue 3, the most recent iteration of the user-friendly Vue JavaScript framework, allows developers to create dynamic front-end applications. In this guide, we will explore how to develop a Whack-a-Mole game using Vue 3 and JavaScript.
Creating the Project
To start our project, we can utilize the Vue CLI. To install it, execute the following command:
npm install -g @vue/cli
Alternatively, if you prefer Yarn, use:
yarn global add @vue/cli
Next, we initialize the project by running:
vue create whack-a-mole
Make sure to select the default options during the setup process.
Building the Whack-a-Mole Game
To construct the game, we will write the following code:
<template>
<button @click="startGame">Start Game</button>
<button @click="endGame">End Game</button>
<p>Score: {{ score }}</p>
<div>
<div v-for="n of 6" :key="n" class="container">
<img
v-if="index === n"
@click="onClick(n)"
/>
<div v-else class="hole"></div>
</div>
</div>
</template>
<script>
export default {
name: "App",
data() {
return {
index: 0,
timer: undefined,
score: 0,
};
},
methods: {
generateIndex() {
this.index = Math.floor(Math.random() * 6);},
startGame() {
this.timer = setInterval(this.generateIndex, 2000);},
endGame() {
clearInterval(this.timer);
this.score = 0;
this.index = 0;
},
onClick(n) {
if (this.index === n) {
this.score++;}
},
},
beforeUnmount() {
clearInterval(this.timer);},
};
</script>
<style scoped>
.hole {
width: 50px;
height: 50px;
border: 1px solid black;
border-radius: 50%;
}
.container {
display: inline-block;
}
img {
width: 50px;
height: 50px;
}
</style>
In this code, we have buttons to start and end the game. When the "Start Game" button is clicked, the startGame method is executed, beginning the game. Conversely, clicking "End Game" invokes the endGame method, which halts the game.
The player's score is displayed in a paragraph element. We dynamically generate the mole's position using the index. If index matches n, the mole image appears; otherwise, a circle is shown.
The mole image includes a click event listener that checks for a successful hit. The component's data method initializes the reactive properties. The generateIndex method randomly selects a new index for the mole's position. The startGame method initiates the game timer using setInterval, while endGame clears the interval and resets the score and index.
When the game is running, clicking on the mole increases the score.
