Phaser.js实现简单的跑酷游戏附源码下载

采用的物理引擎是phaser.js

官网地址：

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）：

   },

  }
 },
 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 enemy; // 敌人
var enemys; // 敌人们
var gameover = false; // 游戏结束

  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

   frame: 4
  }],
  framerate: 20

 // 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;
}
