Player Movement 2D

[1.1.1] - Website link (full docs): https://www.sillylix.com/Docs/2dMovement/Simple-2dMovement.html

A simple, flexible, and lightweight 2D movement system for Unity using Rigidbody2D.
Designed for platforms and top-down games, this script is ideal for fast prototyping while still being robust enough for full projects.

✨ Features

• Camera Follow System – Smooth camera movement that follows the player

• Physics-Based Movement – Uses Rigidbody2D for reliable physics behaviour

• Horizontal & Vertical Movement – Toggle axes to support platformed or top-down game play

• Jump System

  • Single jump

  • Double jump

  • Coyote time (jump grace period)

  • Jump buffer (queue jump before landing)

• Ground Detection – Raycast-based ground check with optional debug visualization

• Dash System – Adjustable dash speed, duration, and key

• Fast Fall – Hold Down Arrow or 'S' to fall faster while airborne

• Input Normalization – Prevents diagonal speed boost

⚙️ Setup Instructions

1️⃣ Adding the Script

• Attach PlayerMovement2D to your player GameObject
  (or use the premade player prefab found in the Prefabs folder)

• The script automatically adds a Rigidbody2D

• A Collider2D is required (any type works — Unity enforces this)

2️⃣ Configuring Movement

• Enable or disable:

  • Horizontal movement

  • Vertical movement

• Set your desired movement speed

• Diagonal movement is automatically normalized

3️⃣ Setting Up Jumping

• Enable Jump for basic jumping

• Enable Double Jump if needed

• Configure:

  • jumpForce

  • gravityScale

  • groundRayLength

• Assign the Ground Layer so the script knows what counts as ground

• Optionally enable Draw Ground Ray to visualize the raycast in the Editor

• Set the jump key (default: Space)

Additional jump features:

• Coyote Time – Jump shortly after leaving the ground

• Jump Buffer – Queue jump input just before landing

4️⃣ Enabling Dashing

• Enable Dash

• Set:

  • dashSpeed

  • dashDuration

• Assign a dash key (default: Left Shift)

5️⃣ Camera Setup

• If using the player prefab, remove your default camera
  → the smooth camera is already included

• Or:

  • Add CameraMovement to any Camera

  • Assign the player as the target

  • Adjust offset and camera speed as needed

🎮 Controls

• Move: Arrow keys or WASD

• Jump: Space (if enabled)

• Dash: Left Shift (if enabled)

• Fast Fall: Hold Down Arrow while airborne

📦 Requirements

• Unity Engine 6000+ (should also work on old ones. not tested)
  (Tested with 6000.0.61f1)

• Rigidbody2D & Collider2D

• Basic knowledge of C# and Unity components
