Graphics / Window draws a white screen instead of map

« on: August 06, 2017, 12:53:46 am »

Hello guys,
So I wanted to draw a tile map, making each tile a different object and then store them in vector, so I can go through it, and tile by tile draw them on the screen. The problem is that instead of a tile map, I get a clean white screen. I'm posting a code, could you help me?

That's my tile map class.

#pragma once

#include <SFML/Graphics.hpp>
#include <iostream>
#include <vector>
#include <string>
#include <fstream>
#include "tile.h"
#include <vector>

class TileMap
{
public:
   std::string source;
   std::vector <Tile> tileContainer;
   TileMap(std::string mapSource)
   {
      source = mapSource;
   }


   void readMap()
   {
      std::fstream plik;
      std::string stringId;
      sf::Vector2f loadCounter(0, 0);
      plik.open(source, std::ios::in || std::ios::out);
      if (plik.good())
      {
         while (!plik.eof())
         {
            plik >> stringId;
            int id = stoi(stringId);
            if (id == 0)
            {
               Tile tile(id, "tiles.png", sf::Vector2f(32, 32));
               tileContainer.push_back(tile);
            }
            else if (id == 1)
            {
               Tile tile(id, "tiles.png", sf::Vector2f(128, 32));
               tileContainer.push_back(tile);
            }
         }
      }
   }


   void drawMap(sf::RenderWindow &okno)
   {

      sf::Vector2f loadCounter(0, 0);
      if (tileContainer.size() != 0)
      {
         for (int i = 0; i < tileContainer.size(); i++)
         {
            tileContainer.sprite.setPosition(loadCounter.x * 32, loadCounter.y * 32);
            okno.draw(tileContainer.sprite);
            std::cout << tileContainer.id;
            loadCounter.x++;
            if (loadCounter.x == 16)
            {
               loadCounter.x = 0;
               loadCounter.y++;
               if (loadCounter.y == 16)
               {
                  loadCounter.y = 0;
                  loadCounter.x = 0;
               }
            }
         }
      }
   }
};

and that's my tile class

#pragma once

#include <SFML/Graphics.hpp>
#include <iostream>
#include <vector>
#include <cmath>
#include <string>

class Tile
{
public:
   float id;
   sf::Texture texture;
   sf::FloatRect bounds;
   sf::Sprite sprite;
   bool walkable;
   Tile(float tileId, std::string tileSource,sf::Vector2f graphCords)
   {
      id = tileId;
      texture.loadFromFile(tileSource);
      sprite.setTexture(texture);
      float x = graphCords.x;
      float y = graphCords.y;
      sprite.setTextureRect(sf::IntRect(x,y, 32, 32));
   }
};
