Build moving platforms (AnimatableBody3D) and add menus, SFX manager, and Windows/Web export
Course Description
Bring your game idea to life by building a complete 3D platformer from the ground up in Godot 4. This beginner-friendly course guides you through the full workflow of creating a playable project that feels like a real game: solid movement, responsive jumping, collectible items, a smooth camera, interactive hazards, win conditions, and a polished presentation. You will learn by doing, creating systems you can reuse in future projects instead of relying on disconnected examples.
Along the way, you will get comfortable inside the Godot editor and learn the practical foundations of GDScript, including how to structure logic, handle input cleanly, and work with constants and control flow for reliable behavior. You will also understand how physics-based characters are organized, why certain node types are best for reusable scenes, and how collision layers and masks keep complex interactions predictable as your project grows.
The course connects common 3D game development tasks into one coherent pipeline. You will move assets between Blender and Godot, import models in a production-friendly format, and set up collision correctly so environments feel solid without creating performance headaches. Visual quality is improved with sensible project settings, and the camera is tuned to follow the player smoothly for a more professional feel.
To make your world engaging, you will add animated collectibles, a coin counter with persistent tracking, and a HUD that stays fixed on-screen over a 3D scene. You will also introduce enemies with reliable collision detection, learn strategies for edge cases like cliffs and slopes, and build moving platforms that behave properly with other bodies. Finally, you will wrap everything up with menu screens, sound effects managed in a clean project structure, and export builds for Windows and the web so you can share your game with others.
