Godot Components: Structuring Your Game Efficiently

Hello Godotneers! When you are creating game in Godot, it is often hard to decide how to structure all your nodes and scenes. Which nodes should go into which scene? Which nodes should talk to each other and when? This video explores ways in which you can create self-contained components in Godot and shows techniques that allow components to access other components and communicate with them while still keeping them usable independently.
