很高兴为您解答这个问题!以下是一个简单的用HTML、CSS和JavaScript实现的找茬游戏的示例代码:
HTML代码:
```
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>找茬游戏</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="picture-container">
<img id="picture1" src="picture1.jpg">
<img id="picture2" src="picture2.jpg">
</div>
<button id="find-differences-button">找茬</button>
<script src="script.js"></script>
</body>
</html>
```
CSS代码:
```
#picture-container {
display: flex;
justify-content: center;
align-items: center;
margin-top: 50px;
}
img {
margin: 20px;
}
#find-differences-button {
display: block;
margin: 0 auto;
margin-top: 50px;
font-size: 24px;
padding: 10px;
}
```
JavaScript代码:
```
const picture1 = document.getElementById("picture1");
const picture2 = document.getElementById("picture2");
const findDifferencesButton = document.getElementById("find-differences-button");
let differences = 0;
picture2.style.opacity = "0.5";
picture2.addEventListener("click", function(event) {
const x = event.pageX - picture2.offsetLeft;
const y = event.pageY - picture2.offsetTop;
const canvas = document.createElement("canvas");
canvas.width = picture2.width;
canvas.height = picture2.height;
const context = canvas.getContext("2d");
context.drawImage(picture2, 0, 0, picture2.width, picture2.height);
const pixel = context.getImageData(x, y, 1, 1).data;
if (pixel[3] === 255) {
differences++;
if (differences === 7) {
alert("你找到了全部的茬!");
differences = 0;
picture2.style.opacity = "0.5";
}
}
});
findDifferencesButton.addEventListener("click", function() {
differences = 0;
picture2.style.opacity = "1";
alert("请找到两张图片中的7处不同之处!");
});
```
这个示例实现了一个简单的找茬游戏,其中包括两张图片(picture1.jpg和picture2.jpg)和一个按钮(find-differences-button)。当用户点击按钮时,游戏开始,图片2的不透明度变为1,用户需要在图片2上找到7处不同之处。当用户找到一个不同之处时,游戏将在图片2上显示一个黑点。当用户找到全部7处不同之处时,游戏结束,提示用户找到了全部的茬。
