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里获得颜色 当我添加颜色时，它会闪烁
如何删除闪烁的
这是我到目前为止所做的游戏。

我可以通过分解在方法中创建字符的调用来看到您已经模块化您的代码。这很好。
但是，由于您使用的是 Object Oriented 语言的C ++，我建议您尝试创建一些 classes 每个字符类型。
<强>闪烁
闪烁可能是因为您的绘图库不是为高性能而设计的。我建议你尝试使用精灵。实际上，您可能希望使用像Cocos2d-x这样的开源2D游戏/精灵库。
游戏引擎会给我什么？
像我上面描述的游戏引擎，使用了多年来开发的许多性能技术，例如纹理打包，查找表等，以提供实时性能。 。 。它仍然需要了解所有这些技术，但是你可能不想从头开始重新实现它们（除非你正在开发自己的游戏引擎）。

要在此处消除闪烁，您可以通过使用函数来使用图形页面的概念： setactivepage（）;和setvisualpage（）;
