　　最近flyppybird很流行啊，今天中午闲着没事干，就用现有的素材写了个flyppyPeople，因为角色是个人，所以就叫People啦，哈哈

　　上链接：http://whxaxes.github.io/canvas-test/src/Game-demo/FlppyPeople/index.html。。。。。。。

　　最近在看createJs，所以就用了createJs来写啦。

　　起跳落下用了简单的自由落体运动公式。动画是通过createJS的精灵表绘制器实现的，话说用框架就是舒服啊，都给你封装好了，哪像楼主写的上一篇博文里的打飞机游戏，精灵表绘制器之类的还得自己手动写。。。。造轮子虽然好玩，不过如果赶时间还是尽量用别人的轮子吧。

　　= =游戏原理很简单。如果园友无聊。。。就可以玩玩

　　游戏有个我故意留的bug，因为楼主玩flyppybird的时候最高只有十分，所以留了那个bug，为了分高一点。。。。仅此而已    = =绝对不是因为楼主懒。。。  = =有人说有bug不好玩，于是还是修复了。。。

代码直接贴啦（因为是随便写来玩的，很多东西可能没考虑完全，性能之类的，将就下吧）：

下面是人物处理js：就是对createJs的sprite对象进行进一步抽象成一个man对象。

(function(w){

    var FRAME_RATE = 13,    //精灵表播放速度

        SCALE_X = 1.5,    //X轴缩放

        SCALE_Y = 1.5,    //Y轴缩放

        GRAVITY = 9.8,    //重力加速度

        JUMP_SPEED = 2.5,        //垂直速度

        PROPORTION = 200/1;  //游戏与实际的距离比例

    w.Man = function(x , y , img){

        this.x = x;

        this.y = y;

        this.vy = 0;

        this.state = "run";

        this.init(img);

    }

    Man.prototype = {

        constructors:Man,

        init:function(img){

            var manSpriteSheet = new createjs.SpriteSheet({

                "images":[img],

                "frames":{"regX":0,"height":64,"count":45,"regY":1,"width":64},

                "animations":{

                    "run":{

                        frames:[21,20,19,18,17,16,15,14,13,12],

                        next:"run",

                        speed:1,

                    },

                    "jump":{

                        frames:[34,35,36,37,38,39,40,41,42,43],

                        next:"run",

                        speed:1,

                    },

                    "die":{

                        frames:[8,7,6,5,4,3,2,1,0],

                        next:"die",

                        speed:1,

                    },

                }

            });

            this.sprite = new createjs.Sprite(manSpriteSheet , this.state);

            this.sprite.framerate = FRAME_RATE;

            this.sprite.setTransform(this.x, this.y, SCALE_X, SCALE_Y);

            stage.addChild(this.sprite);

        },

        update:function(){

            var sprite = this.sprite;

            var time = createjs.Ticker.getInterval()/1000;

            switch(this.state){

                case "jump":

                    sprite.y += time*this.vy*PROPORTION;

                    this.vy += time*GRAVITY;

                    if(sprite.y > this.y && this.vy > 0){

                        sprite.state = "run";

                        sprite.y=this.y;

                        this.vy = 0;

                    }

                break;

                case "die":

                    sprite.y += time*this.vy*PROPORTION;

                    this.vy += time*GRAVITY;

                    if(sprite.y > this.y && this.vy > 0){

                        sprite.y=this.y;

                        this.vy = 0;

                    }

                    if(sprite.currentFrame===0){

                        sprite.paused = true;

                    }

                break;

            }

        },

        jump:function(){

            this.vy = -JUMP_SPEED;

            this.state = "jump";

            this.sprite.gotoAndPlay("jump")

        },

        die:function(){

            this.state = "die";

            this.sprite.gotoAndPlay("die")

        },

        run:function(){

            this.state = "run";

            this.sprite.gotoAndPlay("run")

        }

    }

})(window)

还有阻碍物的js：（就是分成上跟下两部分，总共的石头三块，然后取随机数，让它一个一个出来就行了）

(function(w){

    var STONE_SIZE = 70,

        STONE_NUM = 3,

        STONE_SPEED = 3;

    w.stone = function(x , img){

        this.x = x;

        this.y = 0;

        this.img = img

        this.visible = false;

        this.bones = [];

        this.init();

    }

    var s = stone.prototype;

    s.init = function(){

        for(var g=0;g<STONE_NUM;g++){

            bone = new createjs.Shape();

            bone.graphics.s("#000").f("#59554D").drawRect(0 , 0 , STONE_SIZE , STONE_SIZE);

            bone.x = this.x;

            stage.addChild(bone)

            this.bones.push(bone);

        }

    }

    s.getStoneSize = function(){

        return STONE_SIZE;

    }

    s.update = function(){

        var index=0;

        for(var z=0;z<this.top;z++){

            this.bones[index].x = this.x;

            this.bones[index].y = z*STONE_SIZE;

            index++;

        }

        for(var t=0;t<this.bottom;t++){

            this.bones[index].x = this.x;

            this.bones[index].y = h-this.img.height-(t+1)*STONE_SIZE;

            index++;

        }

        if(this.visible){

            if(this.x<=-STONE_SIZE){

                this.visible = false;

            }

            this.x -= STONE_SPEED;

        }

    }

    s.build = function(){

        this.top = parseInt(Math.random()*STONE_NUM);

        this.bottom = STONE_NUM-this.top;

    }

})(window)
