本篇文章给大家带来的内容是介绍如何实现一个简单的跑酷游戏？(代码详解)。有一定的参考价值，有需要的朋友可以参考一下，希望对你们有所帮助。

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)

效果展示：

源码(详细源码图片资源访问：https://github.com/ProsperLee)

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,

default: 'arcade',

}

},

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

// 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,

frameRate: 10,

repeat: -1

// 动态创建敌人

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
