A simple and efficient 2D character movement system for Unity, designed for both keyboard (WASD / Arrow keys) and gamepad controls.

This script uses Rigidbody2D physics for smooth, responsive motion, and integrates seamlessly with your Animator using Blend Trees.

Perfect for top-down games, 2D RPGs, or adventure projects, this setup gives you full control over your player movement in just a few minutes.

Setup Requirements

Rigidbody2D

• Body Type: Dynamic

• Mass, Linear Drag, Angular Drag, Gravity Scale: very low (0 or near 0)

• Constraint: Freeze Rotation Z (to prevent unwanted spinning)

Animator

• Assign a Controller called PlayerController

• Create two Blend Trees:

  • IdleBT: contains all idle animations (up, down, left, right)

  • Move State: contains all movement animations for the same directions

Box Collider 2D

• Add a Box Collider 2D for collision detection and physics interactions
