Post by: Linux Vs God on July 31, 2011, 08:31:50 pm

How would i get rid of the black lines between each tile in my tilemap?

Code: [Select]

#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include <iostream>
#include <vector>

int main()
{
    std::vector< std::vector<int> > map(4, std::vector<int>(4));
    // Define the map
    map[0][0] = 0;
    map[0][1] = 1;
    map[0][2] = 0;
    map[0][3] = 0;
    map[1][0] = 0;
    map[1][1] = 0;
    map[1][2] = 0;
    map[1][3] = 0;
    map[2][0] = 0;
    map[2][1] = 0;
    map[2][2] = 0;
    map[2][3] = 0;
    map[3][0] = 0;
    map[3][1] = 0;
    map[3][2] = 0;
    map[3][3] = 1;
   
   
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(640, 480, 32), "SFML TileMap");

    // Load the sprite image from a file
    std::vector<sf::Image> images(2);
    if (!images[0].LoadFromFile("grass.png")) {
        return EXIT_FAILURE;
    }
    if (!images[1].LoadFromFile("water.png")) {
        return EXIT_FAILURE;
    }

    // Create the sprite
    std::vector<sf::Sprite> tiles(2);
    tiles[0] = sf::Sprite(images[0]); // Grass
    tiles[1] = sf::Sprite(images[1]); // Water

    // Start game loop
    while (App.IsOpened())
    {
        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Get elapsed time
        float ElapsedTime = App.GetFrameTime();

        // Clear screen
        App.Clear();
       
        for (int x = 0; x < map.size (); x++) {
            for (int y = 0; y < map[x].size (); y++) {
                int tileId = map[x][y];
                // Get the tile's image
                const sf::Image* image = tiles[tileId].GetImage();
                // Get the width and height of the image
                int width = image->GetWidth();
                int height = image->GetHeight();
                // Adjust the offset by using the width
                tiles[tileId].SetPosition(x * width, y * height);
                // Draw the tile
                App.Draw(tiles[tileId]);
            }
        }

        // Display window contents on screen
        App.Display();
       
       
        sf::Sleep(1.0f / 60.0f);
    }

    return EXIT_SUCCESS;
}

This question is asked so often... ;)

Try SetSmooth(false) on your sf::Image

That was a easy fix. Thank you
