@exoticknight 激光那个移动两个块，反射激光就好了，终端里面调整绝对定位的位置，然后加上css3的rotate

@yopming 嗯我已经过了。请问一下有一题猜图，内容是1 1.1. 1.2.……的答案是什么？另外最后一题是提交什么上去呢？我把调整位置后的css代码提交上去似乎不行呢……

@exoticknight 用css把指纹隐藏了就行

@juicy 直接改指纹div的css？话说我是直接看js代码发现最后是跳转到一个页面的于是Base64.decode之后过了……有点无聊

通关没什么难度，如果做一个自动通关脚本还是蛮有意思的。

贴到 console 去。

@baozijianke next-room怎么过？

2013-08-17 03:09:40 +08:00

@exoticknight 哈哈，说明没用kissy，反正肯定是故意把这个给你留着的。比较熟悉这个的人，看到能够随便提交东西，肯定会想到这个的。

17

2013-08-17 03:10:56 +08:00

@66beta 最简单的办法，就是人肉下一页。注意网页的路径，改路径即可。 xxxx?room=12 之类的。

那个脚本语言的是什么意思？

20

exoticknight

2013-08-17 13:23:53 +08:00

@66beta
先在控制台执行这个代码，?t=的后面和'24'根据自己的情况修改：
url='index.php?t=OTk1ZDJjYjhyMzRsRldWd2NDVlF4UkRRNWNCRTlW&room=';
urlreal=url+'24';
strr='';
$.get(urlreal, function(data){
var mess=$(data).find('#message').text();
var number=$(data).find('#next-room').text();
strr=strr+mess;
urlreal=url+number;
console.log(strr);
})
第一次执行完之后在控制台不断执行：
$.get(urlreal, function(data){
var mess=$(data).find('#message').text();
var number=$(data).find('#next-room').text();
strr=strr+mess;
urlreal=url+number;
console.log(strr);
})
最后控制台的输出没变化就得到完整地址了

@xavierskip 先得到页面上的canvas，然后将那些数字分隔成每一个二维码黑点的数据作为参数传入c.fillRect(1,2,3,4)，刚好就是4个参数……其实就是画出二维码出来

22

exoticknight

2013-08-17 13:26:57 +08:00

@baozijianke 第一关和最后一关都能作弊，看看html和js代码就能够发现了

23

xavierskip

2013-08-17 14:34:35 +08:00

@exoticknight 啊，我表达有误。二维码后面一关。有个提示，然后回答什么的，有一个问题就是“脚本语言”，然后一个大大蓝色的圆圈。。想起来了，php。奇葩问题。。

24

exoticknight

2013-08-17 16:43:35 +08:00

@xavierskip 哦哦……那个图案我一看就填php了没有看提示……话说我做了几次，猜图的题目其实不太多
