hello, thanks for the tutorial. i'm having a problem with it though.
i'm not getting errors, it compiles fine, i can move the hero sprite around but,
the tiled level is not rendering. please see screenshot.
below is my "content" and "maps" directories. i don't think i'm missing a file ?
also the map shows correctly in tiled.

How do I compile this with g++?

Hey man,
as a suggestion maybe look into git tagging your repo as you continue to evolve the codebase for each episode. That way you can fetch the state of the repository for that particular episode.

If it's interrupting your workflow too much though, don't bother. Just a suggestion.

git tag -a v0.1 -m 'episode 1'
git push --tags origin

Just doesn't work. I can't find a solution.

Visual studio 2019.

and in graphics.h i get an unexpected token struct.

Main.cpp

/*
    Main.cpp
    Entry point for the program.
*/

#include "game.h"

int main(int argc, const char* argv[]) {
	Game game;
	return 0;
}

graphics.h

#ifndef GRAPHICS_H
#define GRAPHICS_H

struct SDL_Window;
struct SDL_Renderer;

class Graphics {
public:
	Graphics();
	~Graphics();
private:
	SDL_Window* _window;
	SDL_Renderer* _renderer;
};

#endif

Vector2 Level::getTilesetPosition(Tileset tls, int gid, int tileWidth, int tileHeight) {
	int tilesetWidth, tilesetHeight;
	SDL_QueryTexture(tls.Texture, NULL, NULL, &tilesetWidth, &tilesetHeight);
	int tsxx = gid % (tilesetWidth / tileWidth) - 1;
	tsxx *= tileWidth;
	int tsyy = 0;
	int amt = ((gid - tls.FirstGid) / (tilesetWidth / tileWidth));
	tsyy = tileHeight * amt;
	Vector2 finalTilesetPosition = Vector2(tsxx, tsyy);
	return finalTilesetPosition;
}

Why tilesetWidth and tilesetHeight is always 0?
gdb:

When I use an invalid path for the level file, the background is black and Quote can still move around, however, specifying the correct path to my .tmx file causes a Segmentation fault (core dumped) and the window never opens.

This would be very helpful to include a license for your code so we know the terms of using it. Can we re-use it legally(even in proprietary stuff)?(MIT) Does it have to be open-source(GPLv2 or GPLv3)? Thanks for all your hard work!
