c++ - 带图形的 c/c++ 赛车游戏

Question

我正在尝试使用图形在 c/c++ 中制作赛车游戏

我现在的问题是我无法在敌人的车上获得颜色当我添加颜色时它会闪烁

如何消除闪烁

这是我到目前为止制作的游戏。

#include<conio.h>
#include<graphics.h>
#include<dos.h>
#include<process.h>
#include<stdlib.h>

Answer 1

我可以看到您通过将创建角色的调用分解为方法来模块化您的代码。这很好。

但是，由于您使用的是 C++，因此 Object Oriented 语言我建议你尝试创建一些 classes 对于每种字符类型。

闪烁

闪烁可能是因为您的绘图库不是为高性能设计的。我建议您尝试使用 Sprite 。事实上，您可能希望使用像 Cocos2d-x 这样的开源 2D 游戏/ Sprite 库。 .

游戏引擎能给我带来什么？

像我上面描述的游戏引擎，使用了很多多年来开发的性能技术，例如纹理打包、查找表等，以提供实时表现。 . .学习所有这些技术仍然是必要的，但是您可能不想从头开始重新实现它们(除非您正在开发自己的游戏引擎)。
