How It Works

Movement

The script uses:

CharacterController.Move()

for smooth movement based on player direction.

---

Jumping

Jump force is calculated using the physics formula:

v = √(jumpHeight × -2 × gravity)

This creates a cleaner and more realistic jump.

---

Mouse Look

• Horizontal mouse movement rotates the player
• Vertical mouse movement rotates the camera
• Camera rotation is clamped to prevent over-rotation

---

Script Preview

CharacterController.Move(move * moveSpeed * Time.deltaTime);

---

Future Improvements

• Sprint System
• Crouch System
• Head Bobbing
• Footstep Sounds
• Interaction System
• Stamina System
