🧩 Scripts Overview

PlayerController.cs

Handles all core gameplay logic:

• Physics movement via Rigidbody.AddForce() using the Input System
• Pickup collection via trigger detection (Tag: PickUp)
• Win condition: Collect 12 pickups → shows "You Win!", destroys enemy
• Lose condition: Enemy collision → shows "You Lose!"
• Updates the count UI (TextMeshPro) on every pickup

CameraController.cs

• Follows the player with a fixed offset calculated at start
• Runs in LateUpdate() to prevent camera jitter

EnemyMovement.cs

• Uses Unity NavMesh to pathfind toward the player every frame
• Automatically navigates around obstacles in the arena

Rotator.cs

• Rotates pickup cubes continuously on all 3 axes for visual flair
• (15, 30, 45) * Time.deltaTime for smooth, frame-rate-independent spin
