Unity 2D Platformer Game Development Tutorial: Build a Complete Platformer by Daniel Wood

About this course

Turn your game idea into a playable 2D platformer by learning how to build the core systems that make the genre feel responsive and fun. In this free Unity course, you will go from getting comfortable in the editor to assembling a complete project with a character that moves, jumps, animates, and interacts with a level built for platforming. Along the way, you will develop practical workflow habits that help you organize assets, iterate quickly, and avoid common setup mistakes that slow beginners down.

You will start by creating scenes and importing art the right way, then bring your world to life with Unity’s 2D physics. You will see how Rigidbody2D and colliders work together, how friction and bounciness affect movement through Physics Materials, and how to create reusable building blocks with prefabs. From there, you will build environments efficiently using Tilemaps and colliders so your levels feel solid and consistent while staying easy to edit as your game grows.

Once the foundations are in place, the course shifts into scripting essential gameplay behavior in C#. You will implement smooth player movement, reliable jumping, and ground checks so the controls feel predictable. You will also tackle a common platformer pain point—characters catching on ledges—and apply an effective solution so motion stays clean and enjoyable.

To give your character personality, you will create sprite-based animations, set up an Animator Controller, and drive transitions in code. You will also make the character face the direction of travel and implement a camera follow system with adjustable offsets for better readability while playing. As your project becomes more game-like, you will add respawning and checkpoints, manage level transitions between scenes, and build a scoring system that persists correctly across levels.

Finally, you will add player feedback with UI elements such as score display and a health bar that updates smoothly as health changes, including handling damage over time when the player stays in contact with hazards. By the end, you will have a complete small platformer framework you can extend into your own levels, enemies, collectibles, and mechanics—plus portfolio-ready Unity skills that translate directly to future game development projects.
