Player Movement Script for Unity

This script provides first-person movement for a player using the CharacterController component in Unity. It includes:
✔️ Basic movement (WASD)
✔️ Sprinting with limited stamina
✔️ Dynamic Field of View (FOV) changes when sprinting
✔️ Gravity simulation
✔️ Stair detection and smooth climbing

🎮 Features

• Smooth First-Person Movement: Uses Unity's CharacterController for smooth motion.
• Sprinting with Stamina: Sprint depletes over time and regenerates when not in use.
• Realistic Gravity: Keeps the player grounded and prevents floating.
• Stair Climbing: Detects stairs and allows smooth vertical movement.
• FOV Adjustment: Field of View increases while sprinting for a more immersive feel.

2. Set up Layers:
   • Add a "Ground" layer and assign it to ground objects.
   • Add a "Stairs" layer and assign it to stair objects.
   • Set groundMask to Ground and stairsMask to Stairs in the script.
3. Ensure the Player Has a CharacterController component.
