采用的物理引擎是Phaser.js
官网地址：http://phaser.io/
在这里对此引擎不做过多介绍（因为我也是小白，嘿嘿）

源码（详细源码图片资源可点击文章下方或屏幕右上方的github链接进行clone）
1.创建游戏舞台
var config = { type: Phaser.AUTO, width: 800, height: 400, physics: { default: 'arcade', arcade: { gravity: { y: 300 }, debug: false } }, scene: { preload: preload, create: create, update: update }};var game = new Phaser.Game(config); // 创建游戏2.载入资源
function preload() { this.load.image('sky', 'assets/sky.png'); this.load.image('ground', 'assets/platform.png'); 5 6 this.load.spritesheet('dude', 'assets/dude.png', { frameWidth: 32, frameHeight: 48 });}3.将资源创建到舞台上
var distanceText; // 路程文本var distance = 0; // 路程var platforms; // 地面var player; // 玩家var enemy; // 敌人var enemys; // 敌人们var enemyTimer; // 敌人计时器var distanceTimer; // 路程计时器function create() { // 添加画布背景 this.add.image(400, 200, 'sky'); // 添加分数文本 distanceText = this.add.text(16, 16, 'Distance: 0m', { fontSize: '20px', fill: '#000' }); // 添加地面 platforms = this.physics.add.staticGroup(); platforms.create(400, 400, 'ground').setScale(3).refreshBody(); // 添加玩家（精灵） player = this.physics.add.sprite(100, 300, 'dude'); player.setBounce(0); // 设置阻力 player.setCollideWorldBounds(true); // 禁止玩家走出世界 // 敌人 enemys = this.physics.add.group(); enemys.children.iterate(function (child) { child.setCollideWorldBounds(false); }); // 动态创建敌人 enemyTimer = setInterval(function () { enemy = enemys.create(1000, 300, 'dude'); enemy.setTint(getColor()); enemy.anims.play('left', true); enemy.setVelocityX(Phaser.Math.Between(-300, -100)); }, Phaser.Math.Between(4000, 8000)) distanceTimer = setInterval(function () { distance += 1; distanceText.setText('Distance: ' + distance + 'm'); }, 1000) this.physics.add.collider(player, platforms); //玩家在地面上 this.physics.add.collider(enemys, platforms); //敌人在地面上 this.physics.add.collider(player, enemys, hitBomb, null, this);}4.在创建场景过程中写键盘监听事件
var cursors; // 按键 // 事件 this.anims.create({ key: 'left', frames: this.anims.generateFrameNumbers('dude', { start: 0, end: 3 }), frameRate: 10, repeat: -1 }); this.anims.create({ key: 'right', frames: this.anims.generateFrameNumbers('dude', { start: 5, end: 8 }), frameRate: 10, repeat: -1 }); this.anims.create({ key: 'turn', frames: [{ key: 'dude', frame: 4 }], frameRate: 20 }); cursors = this.input.keyboard.createCursorKeys();5.写碰撞函数（当玩家与敌人碰撞的结果）
var gameOver = false; // 游戏结束function hitBomb(player, enemys) { this.physics.pause(); clearInterval(enemyTimer); clearInterval(distanceTimer); player.setTint(0xff0000); gameOver = true; alert('游戏结束,您跑了' + distance + 'm');}6.在update函数中写时间的执行（须注意的是此函数每一帧都在执行，1帧≠1秒）
function update() { if (cursors.up.isDown && player.body.touching.down) { player.setVelocityY(-220); } else { player.anims.play('right', true); } if (gameOver) { player.setVelocityX(0); player.anims.play('turn'); return; }}这里我给敌人上了颜色的，随机16进制颜色
function getColor() { var color = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f"].sort(function(){ return Math.random() - 0.5 }).join("").substr(0,6); return "0x" + color;}整个源码奉上（建议去github上自己clone）：
var config = { type: Phaser.AUTO, width: 800, height: 400, physics: { default: 'arcade', arcade: { gravity: { y: 300 }, debug: false } }, scene: { preload: preload, create: create, update: update }};var game = new Phaser.Game(config); // 创建游戏var distanceText; // 路程文本var distance = 0; // 路程var platforms; // 地面var player; // 玩家var enemy; // 敌人var enemys; // 敌人们var gameOver = false; // 游戏结束var enemyTimer; // 敌人计时器var distanceTimer; // 路程计时器var cursors; // 按键 // 载入资源function preload() { this.load.image('sky', 'assets/sky.png'); this.load.image('ground', 'assets/platform.png'); 39 40 this.load.spritesheet('dude', 'assets/dude.png', { frameWidth: 32, frameHeight: 48 });}// 将资源展示到画布创建资源function create() { // 添加画布背景 this.add.image(400, 200, 'sky'); // 添加分数文本 distanceText = this.add.text(16, 16, 'Distance: 0m', { fontSize: '20px', fill: '#000' }); // 添加地面 platforms = this.physics.add.staticGroup(); platforms.create(400, 400, 'ground').setScale(3).refreshBody(); // 添加玩家（精灵） player = this.physics.add.sprite(100, 300, 'dude'); player.setBounce(0); // 设置阻力 player.setCollideWorldBounds(true); // 禁止玩家走出世界 // 敌人 enemys = this.physics.add.group(); enemys.children.iterate(function (child) { child.setCollideWorldBounds(false); }); // 事件 this.anims.create({ key: 'left', frames: this.anims.generateFrameNumbers('dude', { start: 0, end: 3 }), frameRate: 10, repeat: -1 }); this.anims.create({ key: 'right', frames: this.anims.generateFrameNumbers('dude', { start: 5, end: 8 }), frameRate: 10, repeat: -1 }); this.anims.create({ key: 'turn', frames: [{ key: 'dude', frame: 4 }], frameRate: 20 }); cursors = this.input.keyboard.createCursorKeys(); // 动态创建敌人 enemyTimer = setInterval(function () { enemy = enemys.create(1000, 300, 'dude'); enemy.setTint(getColor()); enemy.anims.play('left', true); enemy.setVelocityX(Phaser.Math.Between(-300, -100)); }, Phaser.Math.Between(4000, 8000)) distanceTimer = setInterval(function () { distance += 1; distanceText.setText('Distance: ' + distance + 'm'); }, 1000) this.physics.add.collider(player, platforms); //玩家在地面上 this.physics.add.collider(enemys, platforms); this.physics.add.collider(player, enemys, hitBomb, null, this);}// 一直执行function update() { if (cursors.up.isDown && player.body.touching.down) { player.setVelocityY(-220); } else { player.anims.play('right', true); } if (gameOver) { player.setVelocityX(0); player.anims.play('turn'); return; }}function hitBomb(player, enemys) { this.physics.pause(); clearInterval(enemyTimer); clearInterval(distanceTimer); player.setTint(0xff0000); gameOver = true; alert('游戏结束,您跑了' + distance + 'm');}function getColor() { var color = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f"].sort(function(){ return Math.random() - 0.5 }).join("").substr(0,6); return "0x" + color;}GitHub：Fuck me on GitHub Fuck me on GitHub
