Question

游戏文件中包含的该.h文件无法识别变量和“在范围内”的函数：

#ifndef GAME_H
#define GAME_H
#include <iostream>

using namespace std;

#include "SDL2/SDL.h"

class Igra
    {
    private:
        SDL_Renderer *obl;
        SDL_Window *okno;
        bool traja;
        Uint32 Takt_zac;
    public:
        Igra();
        ~Igra();
        void zanka();
        void posodobi();
        void vnos();
        void oblikuj();
    };
#endif // GAME_H

我制作的game.cpp：

#include "game.h"

#define fps 60

Igra::Igra()
{
    SDL_Init(0);
    SDL_CreateWindowAndRenderer(360,240,0,&win,&ren);
    SDL_SetWindowTitle(win,"Planet Saver");
    traja=true;
    void loop();
}

Igra::~Igra()
{
    SDL_DestroyRenderer(ren);
    SDL_DestroyWindow(win);
    SDL_Quit();
}

void Igra::zanka()
{
    while(Igra::traja)
    {
        Takt_zac=SDL_GetTicks();
        void kon30(Uint32 Takt_zac);
        oblikuj();
        vnos();
        posodobi();

    }
}
void kon30(Uint32 Takt_zac)
{
    if((1000/fps)>SDL_GetTicks()-Takt_zac)
        SDL_Delay(1000/fps-(SDL_GetTicks()-Takt_zac));
}
void Igra::oblikuj()
{

}
void Igra::vnos()
{

}
void Igra::posodobi()
{

}

编译器产生的错误：

标头中的类不包括所有变量和函数吗？
