Player Movement 2D

A simple and flexible 2D movement system for Unity games, supporting physics-based movement via Rigidbody2D. Perfect for both 2D platformers and 2D top-down games, this script offers smooth player controls with optional jumping (including double jump) and dashing capabilities.

Features

• Camera follow system: smoothly follow player.
• Physics-Based Movement: Utilizes Rigidbody2D for reliable physics interactions.
• Horizontal & Vertical Movement: Toggle movement directions to suit your game design.
• Jumping: Enable single or double jumps with customizable jump force and gravity.
• Ground Detection: Raycast-based system to ensure accurate jump logic (with optional debug visualization).
• Dashing: Temporarily boost movement speed with adjustable dash speed, duration, and key binding.

Setup Instructions

1️⃣ Adding the Script

• Attach the PlayerMovement2D script to your player GameObject or use the premade player (found in prefabs folder).
• The script automatically adds a Rigidbody2D and requires a Collider2D (add any type of collider 2d you want. Unity won't let you put the code unless you put a collider)

2️⃣ Configuring Movement

• Enable or disable horizontal/vertical movement as needed.
• Set your desired player speed.

3️⃣ Setting Up Jumping

• Enable jumpNeeded for basic jumping or dubbleJumpNeeded for double jump functionality.
• Configure the jumpForce, gravityScale, and groundDetectorLength to fine-tune jump behavior.
• Assign the proper Ground Layer to detect when the player is on solid ground.
• Optionally, enable "Draw Jump Detector" to visualize the raycast in the Unity Editor.
• Set the jump key (default is Space).

4️⃣ Enabling Dashing

• Check dashEnabled to allow the dash feature.
• Set the dashSpeed and dashDuration to control dash performance.
• Assign a dash key (default is Left Shift)

5️⃣ Camera

• If you are using the player prefab remove the normal camera and the smooth camera should work
• You can also add this effect to any camera by adding the CameraMovement script.
  • after adding the script you can put your player as target
  • you can also add offset and change the speed of the camera. 

Usage

• Move: Use the arrow keys or WASD to control your player.
• Jump: Press Space (or your chosen jump key) to jump, if enabled.
• Dash: Press Left Shift (or your chosen dash key) to dash, if enabled.

Requirements

• Unity Engine 6000+ (Tested with version 6000.0.35f1)
• Basic knowledge of c# and unity components
