C++实现俄罗斯方块 C++实现俄罗斯方块(windows API)(c语言实现俄罗斯方块)

网友投稿 391 2022-06-06


本文分享的这些俄罗斯方块代码是我最近放假在家里自己写的,虽然以前有过看别人写的代码,但是那个游戏代码好像不是很全面,因为无法实现全部的方块和实现随机的产生任意方向的方块,现在也基本上是忘光了当时的代码,下面的这些代码是我最近写的,没有参考其他人的代码,真正写俄罗斯方块起来感觉真的是挺难的,关键是在于方块的旋转。当然下面的代码仅仅是一个框架,只能够实现大致上的功能,还不全面,贴出来和大家交流学习。

编译器是code::block  +  MinGW ,感觉CB这个IDE真的是太强大,太棒了,下面的代码直接复制到VC里面运行应该不会出错,有个问题一直不知道怎么解决,就是更新客户区时窗口总是闪不知道有哪位达人能指点我一下。有的都是windows API写的,对windows编程还不是很懂,望大家多多留言,指点一下本人。

//下面该函数功能是实现方块旋转,可以说是整个【俄罗斯方块】的难点所在,也是其核心部分 
//方块用以数组block【4】表示,其余3个方格都将围绕block【1】旋转,方块由于有不对称方块 
//存在,我原本是要分7种,但是后面代码量太大了,所以我将方块根据样式归为了四种,分别是: 
// 
//e_LINE 线形   就是一条线的那个,这个是对称的方块,只需分两个方向分别为横向和纵向,方向 
//        用m_direct保持,其他的方块一样 
// 
//e_TANCK 坦克形 这个是方块是对称的,分四种方向,根据m_direct对4进行求余的方法可以大大缩减 
//        代码量,对于下面两种方块也是利用了求余的方式化简许多,才使得代码不会那么冗余, 
//        这是后面我才想到的方法。 
// 
//e_STAIR 楼梯形 这个方块相对前面两种来说有点难度,主要是因为它不是对称的,但是相对下面的这种 
//        来说比较简单,原本我没用对m_direct求余的方法时,我将它分为了e_STAIR_BACK和e_STAIR_FRONT 
//        两类来讨论的,后面发现代码可以缩减才将其归为一类只要记住block【0】和block【1】的位置不会 
//        变化,变化的是block【2】和block【3】,block【2】相对block【1】上移或下移,x坐标与block【1】 
//        相同,block【3】.y一直在block【1】下面一行,相对其左右变化 
// 
//e_CORNER 角形 这个方块个人觉得是最难旋转的方块,与上面一种异样,原本我将它分为e_CORNER_FRONT , e_CORNER_BACK 
//        两类,每类有四个方向的变化,后来根据求余可以将同一个方向的变化变为一种,只是block【3】号方块要 
//        根据m_direct方向来进行调整
