今天搬了一天的家，状态不是很好，分享一个小游戏给大家吧~
先介绍一下游戏规则：
1、点击play后，游戏会提供4中不同的昆虫供玩家进行选择，这四种昆虫分别为：蟑螂、蛛蛛、蚊子和苍蝇。
2、当玩家选择完昆虫后，游戏开始
3、游戏会随机的生成玩家选择的昆虫到电脑屏幕，玩家利用鼠标点击到则得一分。
4、游戏开始时屏幕上显示一只昆虫，随后逐渐增多，同时记录玩家游戏时长
5、一段时间后，弹出小惊喜给玩家
游戏部分截图如下：
- 开始游戏：
- 选择界面：
游戏开始：
一段时间后：
之后弹出惊喜给玩家：
没错，这个时候玩家应该已经发现昆虫是点不完的了，且会越点越多~（大概心态会崩，开始赞美开发者了）
下面老规矩，上代码：
首先是html部分：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <link rel="stylesheet" href="style.css" /> <title>Catch The Insect</title> </head> <body> <div class="screen"> <h1>Catch The Insect</h1> <button class="btn" id="start-btn">Play Game</button> </div> <div class="screen"> <h1>What is your "favorite" insect?</h1> <ul class="insects-list"> <li> <button class="choose-insect-btn"> <p>Fly</p> <img src="http://pngimg.com/uploads/fly/fly_PNG3946.png" alt="fly"> </button> </li> <li> <button class="choose-insect-btn"> <p>Mosquito</p> <img src="http://pngimg.com/uploads/mosquito/mosquito_PNG18175.png" alt="mosquito" /> </button> </li> <li> <button class="choose-insect-btn"> <p>Spider</p> <img src="http://pngimg.com/uploads/spider/spider_PNG12.png" alt="spider" /> </button> </li> <li> <button class="choose-insect-btn"> <p>Roach</p> <img src="http://pngimg.com/uploads/roach/roach_PNG12163.png" alt="roach" /> </button> </li> </ul> </div> <div class="screen game-container" id="game-container"> <h3 id="time" class="time">Time: 00:00</h3> <h3 id="score" class="score">Score: 0</h3> <h5 id="message" class="message"> Are you annoyed yet? <br> You are playing an impossible game!! </h5> </div> <script src="script.js"></script> </body> </html>
紧接着是js部分：
const screens = document.querySelectorAll('.screen');
const choose_insect_btns = document.querySelectorAll('.choose-insect-btn');
const start_btn = document.getElementById('start-btn')
const game_container = document.getElementById('game-container')
const timeEl = document.getElementById('time')
const scoreEl = document.getElementById('score')
const message = document.getElementById('message')
let seconds = 0
let score = 0
let selected_insect = {}
start_btn.addEventListener('click', () => screens[0].classList.add('up'))
choose_insect_btns.forEach(btn => {
btn.addEventListener('click', () => {
const img = btn.querySelector('img')
const src = img.getAttribute('src')
const alt = img.getAttribute('alt')
selected_insect = { src, alt }
screens[1].classList.add('up')
setTimeout(createInsect, 1000)
startGame()
})
})
function startGame() {
setInterval(increaseTime, 1000)
}
function increaseTime() {
let m = Math.floor(seconds / 60)
let s = seconds % 60
m = m < 10 ? `0${m}` : m
s = s < 10 ? `0${s}` : s
timeEl.innerHTML = `Time: ${m}:${s}`
seconds++
}
function createInsect() {
const insect = document.createElement('div')
insect.classList.add('insect')
const { x, y } = getRandomLocation()
insect.style.top = `${y}px`
insect.style.left = `${x}px`
insect.innerHTML = `<img src="${selected_insect.src}" alt="${selected_insect.alt}" style="transform: rotate(${Math.random() * 360}deg)" />`
insect.addEventListener('click', catchInsect)
game_container.appendChild(insect)
}
function getRandomLocation() {
const width = window.innerWidth
const height = window.innerHeight
const x = Math.random() * (width - 200) + 100
const y = Math.random() * (height - 200) + 100
return { x, y }
}
function catchInsect() {
increaseScore()
this.classList.add('caught')
setTimeout(() => this.remove(), 2000)
addInsects()
}
function addInsects() {
setTimeout(createInsect, 1000)
setTimeout(createInsect, 1500)
}
function increaseScore() {
score++
if(score > 19) {
message.classList.add('visible')
}
scoreEl.innerHTML = `Score: ${score}`
}
最后是css部分：

}
.time,
.score {

}
.insect img {

}
最后，祝大家玩的愉快~
