决定将C#Light和C#Evil合并成一个项目,毕竟C#Evil包含C#Light所有的功能,分开两个,基本的表达式方面有什么bug还得两头改 暂时就C#Light/Evil这么叫吧,庆祝合体,画了个新图标. 一周内会迁移完毕 记住C#Light/Evil的地址 http://git.cltri.com (此地址为花生壳跳转,打不开的同学直接用GitHub地址) https://github.com/lightszero/CSLightStudio 另外打算开始写一个系列Blog:Unity3…

C#Light的定位是嵌入式脚本语言,一段C#Light脚本是一个函数 C#Evil定位为书写项目的脚本语言,多脚本文件合作,可以完全用脚本承载项目. C#Light/Evil 使用完全C#一致性语法 目前 C#Light已经是正式版,且经商业项目检验 C#Evil是Alpha版,欢迎试用反馈. C#Evil在C#Light的基础上 从底层支持了面向对象,请注意下面是脚本代码 不同于C#Light没有函数和类的设计,(C#Light只是用C#LightFramework来模拟整个cs文件的识别,…

原题直通车:codeforces 337D Book of Evil 题意:一棵n个结点的树上可能存在一个Evil,Evil危险范围为d,即当某个点与它的距离x<=d时,那么x是危险的. 现已知道有m个点是危险的,问那个Evil可能存的点有多少. 分析: 昨晚傻X地暴力提交,自然得到的是TLE.今天看一神的代码才突然明白…… 跟以往的题一样,两个DFS就可求出答案. 第一个DFS搜出所有危险点,并求出枝干上的点到最远的危险点的距离. 第二次DFS再往回遍历.具体的参考代码. 代码: #inclu…

Eval is evil ('Eval是魔鬼') eval() 函数可计算某个字符串,并执行其中的的 JavaScript 代码.语法:eval(string): eval的使用场合是什么呢?有时候我们预先不知道要执行什么语句,只有当条件和参数给时才知道执行什么语句,这时候eval就派上用场了.举个例子:我们要做一个function(),功能是输入网页中两个个对象的名称,然后程序就将这两个对象的值联接起来输出. function output(a,b) { var tmpa,tmpb; tmpa…
