Beginner platformer tutorial

A beginner game-development thread is steering new developers toward a small platformer project instead of abstract lessons: build movement, collisions, and enemies by finishing a game. (x.com) The project being shared is framed around “Cuboy Adventure,” a side-scrolling platformer format where a player runs, jumps, avoids hazards, and reaches an exit. Steam’s store page for a game by that name describes collectible stars, unlockable abilities, enemies, puzzles, and boss battles, with a demo available and a release date still listed as “coming soon.” (store.steampowered.com) For beginners, the appeal is that a platformer forces a few core systems into one manageable build: a controllable character, a level, objects that block movement, and at least one enemy behavior. Unity’s documentation breaks those pieces into standard components such as Rigidbody 2D for physics motion, Collider 2D for contact detection, and Tilemap Collider 2D for level geometry. (docs.unity3d.com) A collision system is the part that decides when two objects touch, like a player landing on a floor tile instead of falling through it. Unity says Collider 2D components define the shape of 2D objects for physical collisions, and that at least one moving object typically needs a Rigidbody 2D attached for the physics system to register those contacts. (docs.unity3d.com) Level building in this kind of project usually starts with a tilemap, which is a grid of reusable blocks that can become floors, walls, and platforms. Unity’s Tilemap Collider 2D can generate collider shapes from those tiles automatically, and its Composite Collider 2D can merge neighboring shapes to smooth edges and reduce the number of separate collision outlines. (docs.unity3d.com) Enemy behavior in a first project is often kept simple: move between two points, turn around, and damage the player on contact. Unity’s patrol example describes that exact pattern as a common non-player character behavior, using a set of points and a repeated route instead of more complex decision-making. (docs.unity3d.com) That structure matches how major engines pitch beginner learning in 2026. Unity Learn says its courses combine step-by-step tutorials with projects, while GameMaker’s tutorial library includes “Make Your First Platformer” and “How To Move And Collide,” and GDevelop’s academy advertises a beginner platformer tutorial covering movement, enemies, and sound effects. (learn.unity.com) (gamemaker.io) (gdevelop.io) The shared recommendation also leans on a practical habit that many new developers miss: shipping something small. GDevelop markets one-click publishing to Android and Steam, and Unity and GameMaker both organize beginner material around complete, playable projects rather than isolated code snippets. (gdevelop.io) (unity.com) (gamemaker.io) That is why platformers keep showing up in beginner curricula: one character, one camera, one level, and enough rules to teach how a game actually comes together. A tiny finished build teaches more than a folder full of half-tested mechanics. (learn.unity.com)
