前言 几年前接触到一款很好玩的RPG游戏,叫作CPP.最近想着怀念一下,又不想干巴巴地去玩.于是乎,我打算写几篇攻略,主要是记录一下游戏中一些奇妙的点.游戏的第一章是面向对象程序设计,其中又分为基于对象(object-based)的关卡和面向对象(object-oriented)的关卡,而基于对象的关卡中又有两个BOSS,一个是无指针的类,另一个是有指针的类.今天就写写第一关基于对象的无指针的类吧. 基于对象的无指针类 首先介绍一个complex类,这个类是从标准库中提出出来的,有着大佬们的气息…

Array: 1. slice() const newAry = ary.slice() 2. concat const newAry = [].concat(ary) 3. spread opreator: const newAry = [...ary] 4. Array.from: const newAry = Array.from(ary) Object: Shadow copy: 1. object.assign: const newObj = Object.assign({}, obj…

在使用poco version 1.6.0时 Poco::JSON::Array 在object  设置preserveInsertionOrder =true 时 调用 array.stringify出错. 在使用poco::json 输出字符串 std::string str1 = "\r"; std::string str2 = "\n"; Poco::JSON::Object obj1, obj2; obj1.set("payload",…

For example we have an object: const todo = { text: "Water the flowers", completed: false, tags: ["garden"] }; We shallow copy it: const shallowCopy = { ...todo }; Verify that shallowCopy is not todo: console.log(todo === shallowCopy)…

传送门:Boost Graph Library 快速入门 原文:Boost Property Map 图的抽象数学性质与它们被用来解决具体问题之间的主要联系就是被附加在图的顶点和边上的属性(property),比如距离(distance).容量(capacity).权重(weight).颜色(color)等.根据不同的数据结构,有许多方法用来将各种 property 添加到图中,但是作用在图上的算法不需要去关心这些具体的细节.定义在章节 Property Map Concepts中的“属性映射接…

Call custom c++ from Lua cocos2d-x lua binds c++ class, class functions ,enum and some global functions to lua through auto-binding by bindings-generator(tools/bindings-generator) and some manual binding,so we can call custom c++ from lua convenientl…

CCDirector是控制游戏流程的主要组件. typedef enum { /// sets a 2D projection (orthogonal projection)2D投机模式 kCCDirectorProjection2D, /// sets a 3D projection with a fovy=60, znear=0.5f and zfar=1500.3D投影 kCCDirectorProjection3D, /// it calls "updateProjection"…

要保存图像文件,必须先获得图像的编码格式信息.可是GDI+没有直接提供这个函数:GetEncoderClsid(const WCHAR* format, CLSID* pClsid) 因此须要我们自己写一个 GetEncoderClsid 取得图像编码格式的函数 幸好,有 GetImageDecoders函数作为參照 [cpp] view plaincopy #include <windows.h> #include <gdiplus.h> #include <stdio.h…
