Help with C++/SFML

[ImSteves]

I am currently working on adding collision between a Sprite controlled by the player, and the walls of my tile map. At the moment the player can walk on any tile (or no tile at all), so I've been trying to figure out how to differentiate between tiles to no avail. Any help is appreciated, thanks.

#include <SFML/Graphics.hpp>
#include <iostream>
#include <fstream>
#include <Windows.h>

#define HEIGHT 25
#define WIDTH 80

int main()
{

std::ifstream openfile("Map1.txt");

sf::Texture tileTexture;
sf::Sprite tiles;

char map[HEIGHT][WIDTH];
int x, y, colMap[HEIGHT][WIDTH];

sf::Texture Image;
Image.loadFromFile("player.png");
sf::Sprite Sprite(Image);
Sprite.setTextureRect(sf::IntRect(0, 0, 16, 16));

if (openfile.is_open() && !openfile.eof())
{
tileTexture.loadFromFile("tiles.png");
tiles.setTexture(tileTexture);

for (int i = 0; i < HEIGHT; i++)
{
for (int j = 0; j < WIDTH; j++)
{
openfile.get(map[i][j]);

if (map[i][j] == 'U')
{
Sprite.setPosition(j * 16, i * 16);
}
}
}
}

sf::RenderWindow Window(sf::VideoMode(480, 360, 16), "Loading Map");
sf::View Sprite_view(sf::FloatRect(0, 0, Window.getSize().x, Window.getSize().y));

while (Window.isOpen())
{
sf::Event Event;
while (Window.pollEvent(Event))
{
switch (Event.type)
{
case sf::Event::Closed:
Window.close();
break;
}
}

Window.clear(sf::Color(0, 0, 0));

for (int i = 0; i < HEIGHT; i++)
{
for (int j = 0; j < WIDTH; j++)
{
switch (map[i][j])
{
case 'A':
x = 6;
y = 1;
colMap[i][j] = 1;
break;
case 'F':
x = 5;
y = 1;
colMap[i][j] = 0;
break;
case 'W':
x = 0;
y = 0;
colMap[i][j] = 1;
break;
case 'D':
x = 1;
y = 0;
colMap[i][j] = 0;
break;
case 'U':
x = 8;
y = 29;
colMap[i][j] = 0;
break;
case 'S':
x = 8;
y = 0;
colMap[i][j] = 0;
break;
default:
x = 6;
y = 1;
colMap[i][j] = 1;
};

tiles.setPosition(j * 16, i * 16);
tiles.setTextureRect(sf::IntRect(x * 16, y * 16, 16, 16));
Window.draw(tiles);
}
}

if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
{
Sprite.setTextureRect(sf::IntRect(16, 48, 16, 16));
Sprite.move(0, -0.05f);
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
{
Sprite.setTextureRect(sf::IntRect(16, 32, 16, 16));
Sprite.move(+0.05f, 0);
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
{
Sprite.setTextureRect(sf::IntRect(16, 16, 16, 16));
Sprite.move(-0.05f, 0);
}
else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
{
Sprite.setTextureRect(sf::IntRect(16, 0, 16, 16));
Sprite.move(0, +0.05f);
}

Sprite_view.setCenter(Sprite.getPosition());

Window.setView(Sprite_view);
Window.draw(Sprite);
Window.display();
}
}

One technique is to check if the sprites of the various entities intersect using their dimensions. If any intersection is detected, a collision is triggered.
