呵呵，有些长，要使用代码，先打开3DE代码编辑器，网址如下：www.code3Dgames.com/3de
点击有三条横线的菜单按钮，然后选择“new”命令，接着输入一个项目名，再点击“save”按钮，然后删除新项目中的所有代码，再输入我的代码。
我还有以下代码：

作为游戏开发者，工作中难免需要在网上拷贝代码，并且在国内因为某些原因，大家大部分会选择在百度上搜索。并且在搜索结果中CSDN上的内容往往会出现在结果列表的前面。所以大家对这个网站应该是非常熟悉的。
然而不知什么时候开始，当我们需要从CSDN上复制点代码时，上面赫然写着：登录后复制
what？？？
我不知道这个网站的产品经理（也可能是被迫的）对他们的内容质量有多大的自信，大家不过是图个方便，懒得往下翻了。现在居然要求登录后才能复制，这不是故意制造大家的不方便吗？
后来我基本就选择性忽略搜索结果中CSDN的内容，本来上面内容质量就不高，很多广告和重复垃圾，现在还变得盲目自信了，或者也可以叫不要脸了。
骂够了，我们来说说怎么绕过这个人造的坑。
方法一
打开浏览器F2，点击console，输入：
document.body.contentEditable=‘true’
回车搞定，这个方法优点是适用范围广，缺点的稍有麻烦（当然比输入用户名，密码，验证码登录方便点）。
方法二
相比方法一，这个方法更加方便，只需要添加一个书签，并在书签的网址栏输入如下内容：
javascript:document.body.contentEditable=‘true’;document.designMode=‘on’; void 0
然后每次需要复制是，点击一下这个书签即可
方法三
如果连点一下也不想点，那么可以用这个方法。首先添加chrome扩展程序：Simple Allow Copy
然后在拓展程序详情页面，将「允许此扩展程序读取和更改您在所访问的网站上留存的所有数据」选项改为：「在特定网站上」，然后将CSDN的网址添加上即可，如图：
之后就可以复制了，不再需要做任何操作，一劳永逸。唯一一个缺点是安装chrome扩展程序可能需要FQ。
记得关注！
