Creating a fluid movement system is the backbone of any immersive 3D game. In this tutorial, we dive deep into building a robust Unity First-Person Controller that feels responsive and professional. Instead of using basic Transform manipulation, we leverage the CharacterController component to handle collisions and slope limits effectively.

This guide focuses on clean C# scripting and scalable logic. You will learn how to process player input, calculate gravity, and handle ground detection. By the end of this walkthrough, you'll have a modular script ready to drop into any Unity scene, ensuring your player movement is snappy and free of common jitter issues.

Key Features:

• 
  

  Physics-Based Movement: Smooth acceleration and deceleration.

The Implementation

To get started, attach a CharacterController component to your Player GameObject and use the following script:
