Gravity, jumping, platforms and coins, with a proper Player class, delta-time physics, and clean separation of update and draw. Your platformer skills, upgraded to C++.
Build it in our C++ Studio too: lay out a level on a grid, tick the SFML features and download a real main.cpp plus a build file, right in the browser with no install. Open the C++ Mod Studio →
How to run: Save, compile and run: g++ game.cpp -o game -lsfml-graphics -lsfml-window -lsfml-system && ./game

Heads up: SFML 3 renamed a few things. The install step gives you SFML 3 today, but the short snippets in the steps below are written in the classic SFML 2 style. The differences are small and mechanical: sf::VideoMode({800, 500})sf::VideoMode({800, 500}) (curly braces), the new event loop while (const std::optional e = window.pollEvent())while (const std::optional e = window.pollEvent()) with e->is<sf::Event::Closed>()e->is<sf::Event::Closed>(), sf::Keyboard::Key::Leftsf::Keyboard::Key::Left (add ::Key::Key), and setPosition({x, y})setPosition({x, y}) / move({dx, dy})move({dx, dy}) (curly braces). The ? complete finished code at the bottom of this page is full SFML 3 and compiles on a fresh install, use it as your reference.

Need the game setup? Each episode builds a new game on the same C++/SFML skeleton: the sf::RenderWindowsf::RenderWindow, the game loop and event polling. If you're starting here or need that boilerplate, grab it in one click: Episode 1 setup ? âĸ C++ Cheatsheet ?

How it works: write the code in each step, and the canvas on the right shows what your code does. It is a live preview that builds the game as you go. Type to see it update, or press Apply to Canvas to test it straight away.

Lumo says: every step adds one feature to the same game. Type a little, click Apply to Canvas, and test it straight away. There is no wrong answer you can't undo.
