전달 SF :: RenderWindow 참조

Question

그래서 Game 클래스의 기본 창에 타일을 그리고 mapRender 함수에 대한 참조로 주 창을 전달하는 mapReader라는 다른 클래스에서 mapRender 함수를 만들고 있지만 그리지는 않습니다. mainwindow에 타일 ??? 내가 메인 게임 클래스에서 그것을 테스트하고 제대로 작동하지 않습니다, 그냥 제대로 작동하지 않는 창 참조를 전달하려고합니다.

완전한 예 :

MAIN.CPP

#include <Game.h> 

int main() 
{ 
    Game game; 
    game.run(); 
} 

Game.h

#ifndef GAME_H 
#define GAME_H 

#include <iostream> 
#include <Draw.h> 

class Game 
{ 
    public: 
     Game(); 
     void run(); 
     void render(); 

    private: 
     sf::RenderWindow window; 

}; 

#endif // GAME_H 

Game.cpp

#include "Game.h" 

Game::Game() 
{ 
    sf::VideoMode vmode(640,480); 
    window.create(vmode,"Reference passing"); 
    Draw d; 
    d.mapLoader(); 
} 

void Game::run() 
{ 
    while(window.isOpen()) 
    { 
     sf::Event event; 
     while(window.pollEvent(event)) 
     { 
      switch(event.type) 
      { 
      case sf::Event::Closed: 
       window.close(); 
       break; 
      default: 
       break; 
      } 
     } 
     render(); 
    } 
} 

void Game::render() 
{ 
    Draw d; 
    window.clear(); 
    d.mapRender(window); 
    window.display(); 

} 

Draw.h

#ifndef DRAW_H 
#define DRAW_H 

#include <iostream> 
#include <fstream> 
#include <cctype> 
#include <string> 
#include <SFML/Graphics.hpp> 


class Draw 
{ 
    public: 
     void mapLoader(); 
     void mapRender(sf::RenderWindow& rWindow); 
    private: 
     private: 
     sf::Vector2i levelMap[21][16]; 
     sf::Vector2i loadCounter; 
     sf::Texture tileTexture; 
     sf::Sprite tiles; 
}; 

#endif // DRAW_H 

Draw.cpp

#include "Draw.h" 


void Draw::mapLoader() 
{ 
    loadCounter=sf::Vector2i(0,0); 
    if(!tileTexture.loadFromFile("mapSprite.png")) 
     std::cout<<"\n\nMAP LOAD FAILED!\n"<<std::endl; 
    tiles.setTexture(tileTexture); 

    std::ifstream openFile; 
    openFile.open("mapfile.txt"); 
    loadCounter=sf::Vector2i(0,0); 
    if(openFile.is_open()) 
    { 
     while(!openFile.eof()) 
     { 
      std::string str; 
      openFile>>str; 
      char x=str[0],y=str[2]; 
      if(!isdigit(x)&&!isdigit(y)) 
       levelMap[loadCounter.x][loadCounter.y]=sf::Vector2i(-1,-1); 
      else 
       levelMap[loadCounter.x][loadCounter.y]=sf::Vector2i(x-'0',y-'0'); 

      if(openFile.peek()=='\n') 
      { 
       loadCounter.x=0; 
       loadCounter.y++; 
      } 
      else 
      loadCounter.x++; 
     } 
     loadCounter.y++; 
    } 

} 

void Draw::mapRender(sf::RenderWindow& rWindow) 
{ 
    for(int i=0;i<20;i++) 
    { 
     for(int j=0;j<15;j++) 
     { 
      if(levelMap[i][j].x!=-1 && levelMap[i][j].y!=-1) 
      { 
       tiles.setPosition(i*32,j*32); 
       tiles.setTextureRect(sf::IntRect(levelMap[i][j].x*32,levelMap[i][j].y*32,32,32)); 
       rWindow.draw(tiles); 
      } 
     } 
    } 
}

Answer 1

당신은 당신이 그것을 사용하는 시간 Draw d;의 새로운 인스턴스를 재 작성하십시오. 이 인스턴스를 번 (예 : 클래스 멤버로)으로 만들고이를 사용하십시오. d에지도를로드하기 때문에 그림에 사용할 d과 같지 않습니다.
