Current Features

Camera

• TPS mode (default): Third-person view with scroll zoom
  • Camera collision (prevents clipping into walls and ground)
  • Free rotation via Yaw/Pitch
• FPS mode: First-person view from the player's eye level
• Auto cursor unlock on Alt+Tab

Player

• Capsule collider with 3D character model (GLB from Mixamo)
• RigidBody::Kinematic with custom character controller
  • Custom gravity, ground detection, and collision resolution
  • Move-and-slide: wall sliding using normal projection
• Ground detection via shape cast
• Player rotates towards movement direction
• PlayerState component for state management (Idle / Walking / Running / Jumping / Falling / CrouchIdle / CrouchWalking / Floating / Flying)
• Crouch: collider resize + camera offset + ceiling check (can_stand)
• Falling: terminal velocity clamp / dive mode (Shift during fall: 3× gravity, higher terminal velocity)
• Flight: Floating (normal speed) and Flying (Shift boost) with full 6DoF movement
• Animations: Idle / Walk / Run / Jump / Falling / CrouchIdle / CrouchWalking / Floating / Flying
