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;
    if (!tile.loadFromFile(resourcePath() + "tiles.png")) {
        return EXIT_FAILURE;
    }
   
    sf::Sprite sky(tile);
    sky.setTextureRect(sf::IntRect(0, 0, 32, 32));
   
    sf::Sprite brick(tile);
    brick.setTextureRect(sf::IntRect(32, 0, 32, 32));
   
    sf::Sprite grass(tile);
    grass.setTextureRect(sf::IntRect(64, 0, 32, 32));
   
    sf::Sprite stone(tile);
    stone.setTextureRect(sf::IntRect(96, 0, 32, 32));
   
    // collision for other tiles
    sf::FloatRect stoneBox;
   
    // Start the game loop
    while (window.isOpen())
    {
        // Process events
        sf::Event event;
        while (window.pollEvent(event))
        {
            // Close window: exit
            if (event.type == sf::Event::Closed) {
                window.close();
            }

            // Escape pressed: exit
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Escape) {
                window.close();
            }
        }
       
        // Player
        player.setOrigin(-320, -240);
       
        float movementSpeed = 5.0;
        if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up)) {
            player.move(0, -movementSpeed);
            if (playerBox.intersects(stoneBox)) {
                player.move(0, movementSpeed);
            }
           
            player.setTextureRect(sf::IntRect(96, 0 + (counter2 * 48), 48 , 48));
            counter1++;

            }
       
            player.setTextureRect(sf::IntRect(144, 0 + (counter2 * 48), 48 , 48));
            counter1++;

                break;
        }
       
        // Clear screen with white
        window.clear(sf::Color::White);

        // Draw the sprites
        for (int x = 0; x < 20; x++) {
            for (int y = 0; y < 15; y++) {
                window.draw(drawTile(x, y, brick));
            }
        }
        for (int x = 0; x < 20; x++) {
            for (int y = 0; y < 15; y++) {
                window.draw(drawTile(0, y, stone));
                window.draw(drawTile(19, y, stone));
            }
            window.draw(drawTile(x, 0, stone));
            window.draw(drawTile(x, 14, stone));

Start your application in a debugger and step through you collision code to see what is going on. Compare the actual values against expected values.
