我不知道你们有些人是否发生了这种情况。我还没有开始编程，因为“我不知道从哪里开始”。我想制作一个平台视频游戏，8位一个。是的，这将花费大量的时间和技巧，但我总是喜欢跳到复杂的东西。
我是那种喜欢使用最新程序的人。所以我使用Visual Studio 2017，但SFML最高可达VS2015。有没有办法使用SFML是VS2017？我该怎么办？
答案 0 :(得分：2)
首先，祝贺您开始编程之旅！
然而，作为一名辅导了许多有相同抱负的孩子（例如学习C ++制作视频游戏）的人，我建议你从简单的道路开始。
我不会尝试学习C＃或Java或其他语言，因为我和其他许多人实际上都是从C开始的;它不是关于学习特定语言，而是关于理解整个系统。线程，对象，循环或函数的概念不会改变，它是如何利用语言之间的变化。
我是那种喜欢使用最新最新节目的人。
虽然这可能对大多数程序有利，但由于错误修复或其他增强功能，对于开发环境而言并非如此。更新Visual Studio时，通常会更新整个工具链：编译器，链接器，SDK等等。
这意味着可以引入错误的编译器，或者将代码标记为已弃用，以及其他需要考虑的问题。特别是在开发类似游戏的东西时。
我还没有开始编程因为＆＃34;我不知道从哪里开始＆＃34;
这是一款模拟2名玩家的简单"war"纸牌游戏;它会自动播放战争，直到赢得比赛。它会重复这一过程，直到收到中断信号（CTRL+C）并打印出任何游戏中的最大转弯次数，以及我们的自动玩家所玩的任何游戏中的最小转弯次数。 ＃39;
它在C ++中，可以修改为用户输入二十一点或扑克游戏，你可以在任何系统上构建它就足够了。
此代码用于教学，因此您可以使用此代码，修改代码，构建代码，运行代码以及了解每个步骤中发生的情况。
从那里，您可以了解更多信息，提出更多问题，最终您可以使用SFML制作2D平台游戏。

请注意，SFML现在可以在VS2017上正常使用。
我有2.5版的二进制文件，无需编译。
请参阅此处的说明：
