提问by aditya mithal
I am trying to make a racing game in c/c++ using graphics

my problem as of now is that i cant get color in the enemy car when i add color it flickers

I can see that you've modularizedyour code by breaking up the calls to create characters into methods. This is good.
我可以看到您通过将创建字符的调用分解为方法来模块化代码。这很好。
However, since you're working in C++, which is an Object Orientedlanguage I recommend that you try to create some classesfor each of the character types.
但是，由于您使用的是 C++，这是一种面向对象的语言，我建议您尝试为每种字符类型创建一些类。
Flickering
闪烁
The flickering is probably because your drawing library is not designed for high performance. I recommend that you try using sprites. In fact you might wish to use an open-source 2D games/sprite library like Cocos2d-x.
闪烁可能是因为您的绘图库不是为高性能而设计的。我建议您尝试使用精灵。事实上，您可能希望使用像Cocos2d-x这样的开源 2D 游戏/精灵库。
What will a games engine get me?
游戏引擎会给我带来什么？
A games engine like the one I described above, uses a lot of performance techniques that have been developed over the years, such as texture packing, look-up tables, etc to provide real-time performance. . . its still necessary to be learning about all of these techniques, however you probably don't want to be re-implementing them from the ground up (unless you're developing your own games engine).
像我上面描述的那样的游戏引擎，使用了许多多年来开发的性能技术，例如纹理打包、查找表等，以提供实时性能。. . 仍然有必要学习所有这些技术，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）。
回答by Yash Sharma
To remove flickering here you can use the concept of graphical pages by using functions: setactivepage( ); and setvisualpage( );
要在此处消除闪烁，您可以通过使用以下函数来使用图形页面的概念： setactivepage( ); 和 setvisualpage();
