c++ static关键字

static关键词声明成员变量,作用为在所有实例中保存同一个变量.
在.h中这样声明:

class CStage
{
public:
	CStage(void);
	~CStage(void);
	static float key_timer;
	static float countdown_timer;
};

在.cpp中这样初始化:

#include "Stage.h"

CStage::CStage(void)
{
}

CStage::~CStage(void)
{
}

float CStage::key_timer = -1.0f;
float CStage::countdown_timer = 180.0f;
