In this Unity tutorial, you will learn how to create smooth 2D player movement using the new Unity Input System.
Starting from a simple scene setup, we’ll build a player controller step by step, add Rigidbody2D physics, read movement input using Unity’s new input system, and improve the movement using Vector2.SmoothDamp to make it feel smooth and responsive.
Along the way, we’ll also fix common issues like unwanted Z-axis rotation and implement a simple flip logic so the character always faces the direction it moves.
This tutorial is designed for beginners, but it also covers techniques that are commonly used in real game projects.
Topics covered in this video:
• Setting up Unity’s New Input System
• Reading movement input using Input Actions
• Rigidbody2D based character movement
• Fixing Z-axis rotation issues
• Implementing smooth movement with SmoothDamp
• Character flip logic for left and right movement
