Creating an Exciting Hi-Low Card Game with Vue 3 and JavaScript
Written on
Introduction to Vue 3
Vue 3 represents the latest iteration of the user-friendly Vue JavaScript framework, which allows developers to build dynamic front-end applications. In this guide, we will explore the steps to create a hi-low card game using Vue 3 and JavaScript.
Setting Up the Project
To initiate our Vue project, we utilize the Vue CLI. Installation can be accomplished using the following commands:
npm install -g @vue/cli
or
yarn global add @vue/cli
After the installation, we create our project by running:
vue create hi-low-game
We will select all default settings to set up our project seamlessly.
Developing the Hi-Low Card Game
To construct the hi-low game, we will use the following code:
<template>
<form @submit.prevent="draw">
<select v-model="guess">
<option>lower</option>
<option>higher</option>
</select>
<button type="submit">guess</button>
</form>
<p>score: {{ score }}</p>
<p>last drawn card</p>
<img
v-if="drawnCards[drawnCards.length - 2]"/>
<p>currently drawn card</p>
<img
v-if="drawnCards[drawnCards.length - 1]"/>
</template>
<script>
const suits = ["diamonds", "clubs", "hearts", "spades"];
const values = ["ace", 2, 3, 4, 5, 6, 7, 8, 9, 10];
const cards = [];
for (const s of suits) {
for (const v of values) {
cards.push(${s}_${v});}
}
export default {
name: "App",
data() {
return {
score: 0,
cards: [...cards].sort(() => Math.random() - 0.5),
drawnCards: [],
guess: "lower",
};
},
methods: {
draw() {
const drawnCard = this.cards.pop();
this.drawnCards.push(drawnCard);
const indexLastCard = cards.indexOf(
this.drawnCards[this.drawnCards.length - 2]);
const indexDrawnCard = cards.indexOf(
this.drawnCards[this.drawnCards.length - 1]);
if (
(indexLastCard < indexDrawnCard && this.guess === "higher") ||
(indexLastCard > indexDrawnCard && this.guess === "lower")
) {
this.score++;}
},
},
};
</script>
In the template section, we create a form that includes a dropdown menu allowing players to choose if the next card will be higher or lower than the previous one. The @submit.prevent directive captures the submit event, enabling client-side handling without a full page refresh.
We display the player's score beneath the form, along with images of the last and currently drawn cards.
In the script section, we set up the cards array by combining values from the suits and values arrays. The data method contains reactive properties including the current score, a shuffled deck of cards, the drawn cards, and the player's guess.
The draw method handles drawing a card, updating the drawn cards array, and checking the player's guess against the drawn cards to update the score.
