         最近项目中需要加入一些模型移动的小动画,学习过程中发现了iTween这个类库.它主要的功能就是处理模型从起始点到结束点之间运动的轨迹.(移动,旋转,音频,路径,摄像机等)它是一个开源的项目并且完全免费,它们的官网在这里 http://itween.pixelplacement.com/index.php 打开网之后点击右上角Get iTween图标即可,或者在AssetStores商店中直接下载. 我把iTween的源码仔细读了一遍,我感觉与其说它是处理动画的类,不如说它是处理…

http://blog.chinaunix.net/uid-20726254-id-3486721.htm 这个绝对是新增的top特性,篇幅非常多.看着就有点费劲,总结更费劲. 原来的标准当中,参数与返回值的传值形式涉及到对象的复制,传值完成后,中间产生的临时对象又会马上被销毁,某些自定义的对象或者容器有很多元素时复制的开销非常大,而且例如IO对象或unique_ptr对象也不允许复制:传址在返回值的某些场景又会有局部对象的问题.c++11中新增了move的概念,用一个词描述就是"steal&q…

看了很多篇文章,现在终于搞懂了C++ 中的右值以及std::move   左值和右值最重要的区别就是右值其实是一个临时的变量 在C++ 11中,也为右值引用增加了新语法,即&&   比如如下代码: void testFunc(int &i ) { std::cout<<"reference test func int"<<std::endl; } void testFunc( int &&i ) { std::cout&l…

[update: 关于左值右值的另一点总结,请参看这篇] 一. move 关于 lvaue 和 rvalue,在 c++11 以前存在一个有趣的现象:T&  指向 lvalue (左传引用), const T& 既可以指向 lvalue 也可以指向 rvalue.但却没有一种引用类型,可以限制为只指向 rvalue.这乍看起来好像也不是很大的问题,但实际与看起来不一样,右值引用的缺失有时严重限制了我们在某些情况下,写出更高效的代码.举个粟子,假设我们有一个类,它包含了一些资源: class…
