Unity 2D Platformer (Portfolio Project)

This project is a 2D platformer game developed using Unity (C#) as a portfolio piece for a game development internship application.

Project Purpose

The primary goal of this project is to demonstrate core competencies in the Unity engine and the C# language. The project includes all the fundamental mechanics that constitute a "core gameplay loop".

Core Features

• Physics-Based Character Controller: Fluid movement and jumping implemented using Rigidbody2D.
• 4-Way Sensor System: A jump system based on Physics2D.OverlapCircle that can detect the ground from all 4 surfaces (bottom, top, right, left), even if the character rotates.
• Camera Follow: A simple and smooth LateUpdate camera script that follows the player.
• Scoring & Collectibles: "Coin" collection using OnTriggerEnter2D and a GameManager to update the score to the UI using TextMeshPro.
• Win Condition: The player can trigger a "You Win!" screen (SetActive(true)) by touching a "FinishLine" object.

Management & Scripts

This project adheres to the Separation of Concerns principle. The main scripts are:

• PlayerController.cs: Manages all player input (Input.GetAxis), movement physics (rb.velocity), and the 4-way jump sensor logic.
• CameraController.cs: Uses LateUpdate() to ensure the camera follows the player (target) without jitter.
• GameManager.cs: Acts as the "brain" of the game. It holds the score, references UI elements (ScoreText, WinText), and updates them.
• Collectible.cs: The script for "Coin" objects. It detects collision with the player (CompareTag("Player")) and signals the GameManager to add score.
• LevelFinish.cs: Detects when the finish line is touched, tells the GameManager to show the win screen, and also disables player movement (PlayerController.enabled = false).
