web前端-js教程
想转html5游戏开，这是学习练手的东西，最开始是用面向过程的方式实现，后面用面向对象的方式实现(被坑了)……
威客整站源码,ubuntu可以不分usr,用.net做爬虫,<php src,seo网站监控lzw
演示地址:/detail/ss8pkzrc
php小说源码cms,vscode的node配置,ubuntu 网络叠加,tomcat接口测试,sqlite重复初始化,蚂蚁金服前端框架和工程化,爬虫需要一台电脑,php附件大小,seo网络竞价收录,dedecms 图片网站,教育网页源文件,网站后台怎么上传网页模板lzw
html代码
论坛功能源码,ubuntu下运行jar,爬虫工具哪种好,php技术设计管理信息系统学习,锦州seo托管lzw
/** 游戏规则：一个玩家、两个色子，每个色子有1-6个点，点数随机出现，点数是2-12中的任意数字如果玩家第一次抛出 7 或者 11，则本回合胜利 进行下一回合如果玩家抛出2、3、12 则回合失败 进行下一回合抛出其他数字4、5、6、7、8、9、10 记录点数和，并继续掷色子当玩家掷出7 则本回合失败 进行下一回合当玩家抛出的点数和与上一次的相同，本局胜利 进行下一回合当玩家抛出的点数和与上一次的不同，本局失败，进行下一回合 game:{游戏对象 } Stage={场景对象add(thing) //添加一个物件addEvent(type,handler)redraw() //重绘所有thing对象 } Thing = {//物件对象draw(canvas)//传入一个canvas画板对象用于绘制thingisScope(x,y) //传入鼠标相对于canvas的位置，返回boolean， //用于判断鼠标是否在thing的范围 true在，false不在addEvent(type,handler) //公开方法 //给物件设置时间 } 定义我们自己的场景对象 掷色子的场景内需要：1、两个色子 色子一号 色子二号2、一个公告板 显示本局信息3、三个按钮 重现开始 **/ function Stage(canvas){ this.canvas = document.getElementById(canvas); this.ctx = this.canvas.getContext(2d); this.ctx.lineWidth = 1; this.ctx.strokeStyle = gb(255,0,0); this.width = this.canvas.width; this.height = this.canvas.height; this.things = []; this.addEvent = []; this.rule = {};}Stage.prototype.setings = function(){};Stage.prototype.draw = function(){ for(var thing in this.things){if(this.things[thing] instanceof Array){ for(var i=0;i<this.things[thing].length;i++){ this.things[thing][i].init(); }} }}Stage.prototype.add = function(thing){ if(!thing){return;} if(this.things[disc] == undefined){this.things[disc] = []; } if(this.things[callBoard] == undefined){this.things[callBoard] = []; } if(thing instanceof Disc){this.things[disc].push(thing); } if(thing instanceof CallBoard){this.things[callBoard].push(thing); }}Stage.prototype.play = function(){ this.clean(); for(var i=0;i 0 ?
