Overview

This Unity 3D first-person shooter project demonstrates essential game development mechanics, focusing on player movement, camera, environmental interaction, and combat systems in a simple 3D level. Key features include:

Level Design

• Basic level built with simple objects (e.g., planes and cubes).
• Includes corridors, stairs, moving platforms, and an abyss.

Player Mechanics

• Smooth movement with WSAD keys (forward/backward/strafe).
• Mouse-based rotation and jumping with the Space key.
• Prevents falling off the level while allowing controlled jumps.

Power-Ups

• Speed and jump boost (+50%) for a limited time.
• Damage enhancement for the player's weapon.

Combat System

• Two weapons:
  • Fast-firing weapon (25 HP damage per shot).
  • Splash-damage weapon (125 HP per shot).
• Two types of stationary enemies:
  • 200 HP and 500 HP.
  • Enemies change color based on health: green > yellow > red.

UI Integration

• Simple user interface displaying the player's state (e.g., moving, jumping).

Architecture

Design Patterns

• Component-Based Architecture
  • Separate components: PlayerController, CameraController, Health.
• Observer Pattern
  • Events: Health.OnHealthChanged, PlayerController.OnPlayerStateChanged.
• State Pattern
  • PlayerState structure in PlayerController.
• Interfaces
  • IDamageable implemented by Enemy and Player.
• Inheritance
  • Base class PowerUp extended by SpeedBoost.

---

Unity Techniques

• Serialized Fields
  • Example: [SerializeField] private float moveSpeed in controllers.
• Rigidbody Physics
  • Example: PlayerController.Move() using rb.velocity.
• Raycasting
  • Example: Ground check in PlayerController.GroundCheck() using Physics.Raycast.
• Coroutines
  • Example: Temporal effects like EnemyController.ShakeOnDamage().

---

Programming Practices

• Event-Based Communication
  • Example: UIManager subscribing to Health.OnHealthChanged.
• Component Caching
  • Example: rb = GetComponent<Rigidbody>(); in the Start() method.
• Smooth Interpolation
  • Example: Camera movement using SmoothDamp in CameraController.
• Object Pooling for Projectiles
  • Managed by a ProjectilePool.

---

Gameplay Systems

• Health System
  • Methods: Health.TakeDamage(), Health.Heal().
• Moving Platforms System
  • Controlled by the MovingPlatformController.
• Power-Up System
  • Virtual methods: PowerUp.Activate(), PowerUp.Deactivate().
• Visual Feedback Mechanism
  • Material color change in the EnemyController upon receiving damage.
