Unity fundamentals

Understand what Unity stores in a scene, how components attach to GameObjects and why prefab instances make reuse possible. These foundations make the editor, scripting and physics lessons much easier.

Lessons and practical examples

• Hierarchy and Transforms: Parenting, local/world coordinates and component organization.

• Prefabs, variants and overrides: Build reusable objects without losing instance-specific settings.

• Scenes and GameObjects: Understand scene files, objects and components and how the runtime uses them.
