I'm back. I've made an amount of progress with my game, and the help that I previously recieved was awesome. I now have a new issue though. I have followed the structure of the vertex array tutorail to the 'T', and also tried to follow the advice given in my previous post. The map that I am drawing from (the [] itself) isn't 100% truly rendered as it was described in the code. Some tile aren't spawning where they are supposed to be, and tiles are replacing other tiles in random areas.
Most of this is directly from the tutorial and has been adapted to suit my classes.
Nothing looks amiss when compared to the tutorial so I'm stumped.
bool TileMap::load(const std::string& tileset, sf::Vector2u tileSize, const int* tiles, unsigned int width, unsigned int height)
{
// load the tileset texture
if (!m_tileset.loadFromFile(tileset))
return false;
// resize the vertex array to fit the level size
m_vertices.setPrimitiveType(sf::Quads);
m_vertices.resize(width * height * 5);
// populate the vertex array, with one quad per tile
for (unsigned int i = 0; i < width; ++i)
for (unsigned int j = 0; j < height; ++j)
{
// get the current tile number
int tileNumber = tiles[i + j * width];
// find its position in the tileset texture
int tu = tileNumber % (m_tileset.getSize().x / tileSize.x);
int tv = tileNumber / (m_tileset.getSize().x / tileSize.x);
// get a pointer to the current tile's quad
sf::Vertex* quad = &m_vertices[(i + j * width) * 4];
// define its 4 corners
quad[0].position = sf::Vector2f(i * tileSize.x, j * tileSize.y);
quad[1].position = sf::Vector2f((i + 1) * tileSize.x, j * tileSize.y);
quad[2].position = sf::Vector2f((i + 1) * tileSize.x, (j + 1) * tileSize.y);
quad[3].position = sf::Vector2f(i * tileSize.x, (j + 1) * tileSize.y);
// define its 4 texture coordinates
quad[0].texCoords = sf::Vector2f(tu * tileSize.x, tv * tileSize.y); //grass

From the first image you can see that the amount of shrubs do not match to the tile numbers in the array and that the boundary tile does not spawn on the left side but does on the top.
The second image is my atlas.
The third image is what happened on the bottom right corner of the screen.
EDIT:For all of the texCoords lines I am getting a compiler warning -> C4244 'argument': conversion from 'unsigned int' to 'T', possible loss of data. Could this have something to do with generating the map badly if some values are being lost??
