移动端JavaScript赛车游戏通常涉及HTML5 Canvas API来渲染图形,以及一些物理引擎来模拟赛车的运动。以下是一个简单的示例代码,展示了如何创建一个基本的赛车游戏:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>赛车游戏</title>
<style>
canvas {
display: block;
margin: auto;
background: #f0f0f0;
}
</style>
</head>
<body>
<canvas id="raceCanvas" width="800" height="600"></canvas>
<script src="race.js"></script>
</body>
</html>
const canvas = document.getElementById('raceCanvas');
const ctx = canvas.getContext('2d');
class Car {
constructor(x, y, width, height, color) {
this.x = x;
this.y = y;
this.width = width;
this.height = height;
this.color = color;
this.speed = 0;
}
draw() {
ctx.fillStyle = this.color;
ctx.fillRect(this.x, this.y, this.width, this.height);
}
update() {
this.x += this.speed;
if (this.x > canvas.width) {
this.x = -this.width;
}
}
}
const car = new Car(0, canvas.height / 2 - 25, 50, 50, 'red');
function gameLoop() {
ctx.clearRect(0, 0, canvas.width, canvas.height);
car.update();
car.draw();
requestAnimationFrame(gameLoop);
}
document.addEventListener('keydown', (e) => {
if (e.key === 'ArrowRight') {
car.speed = 5;
}
});
document.addEventListener('keyup', (e) => {
if (e.key === 'ArrowRight') {
car.speed = 0;
}
});
gameLoop();
requestAnimationFrame
实现的。这个示例提供了一个非常基础的赛车游戏框架,实际开发中可能需要更复杂的逻辑,如碰撞检测、多辆赛车、赛道设计等。
