General / Wall Tile Collision only works for one tile

« on: September 17, 2017, 08:06:50 am »

Collision only seems to work for the tile in the top left corner. Maybe it is because of how I made the tiles? I yet an amateur in game development and programming in general (btw).

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
#include <math.h>
#include <iostream>
#include "ResourcePath.hpp"

sf::Sprite drawTile(int x1, int y1, sf::Sprite sprite) {
    x1 = x1 * 32;
    y1 = y1 * 32;
    sprite.setPosition(x1, y1);
    return sprite;
}

int main(int, char const**)
{
    // 20 x 15
    const int WIDTH = 640;
    const int HEIGHT = 480;
    int counter1 = 0;
    int counter2;
   
    // Create the main window
    sf::RenderWindow window(sf::VideoMode(WIDTH, HEIGHT), "ummmm");
    window.setVerticalSyncEnabled(true);

    // Set the Icon
    sf::Image icon;
    if (!icon.loadFromFile(resourcePath() + "pokemon.png")) {
        return EXIT_FAILURE;
    }
    window.setIcon(icon.getSize().x, icon.getSize().y, icon.getPixelsPtr());

    // Load player texture and sprite
    sf::Texture betty;
    if (!betty.loadFromFile(resourcePath() + "betty.png")) {
        return EXIT_FAILURE;
    }
    sf::Sprite player(betty);
    player.setTextureRect(sf::IntRect(0, 0, 48 , 48));
   
    // collision box for player
    sf::FloatRect playerBox;
   
   
    // Load sky texture and sprite
    sf::Texture tile;
