C. Creating reusable Prefabs for modular development
Unity Prefabs allow you to create templates of GameObjects that can be reused and updated across your project. For example, you can design an enemy unit once and reuse it in multiple levels. If you update the original Prefab, all instances reflect the change. This promotes modularity, consistency, and speeds up level design—key for scaling projects and reducing repetitive work.
5. Game Logic with C# Scripting
A. Writing your first scripts to move characters and objects
In this module of the Unity game development course, you’ll dive into C# scripting, the backbone of interactivity in Unity. You’ll start by creating simple scripts that control character movement or object behaviors—like rotating a cube or moving a player based on keyboard input. Through this, you’ll understand Unity’s component-based scripting system, where scripts are attached to GameObjects as behaviors.
B. Handling input, collisions, and basic interactions
Next, you’ll learn how to use Unity’s Input System to detect user actions like key presses, mouse clicks, or touchscreen gestures. You’ll also implement collision detection using Unity’s physics engine—responding to events like a player hitting a wall or picking up a coin.
