Current Features

✅ First-Person Player Controller (FirstPersonController.cs)

• Built for Unity Netcode for GameObjects (NGO)
• Server-authoritative movement with client-side prediction (host excluded for accuracy)
• Player input is serialized via a PlayerMovementInputData struct and sent to the server each frame using RPCs
• The server processes all movement logic and updates animation states
• Camera pitch is synchronized with a NetworkVariable<float>
• Non-owners are prevented from controlling the CharacterController or camera directly
• Supports:
  • Sprinting, jumping, gravity, fall detection
  • Ground check using physics sphere
  • Smooth acceleration & deceleration
  • Mouse and gamepad look input
  • Vertical camera pitch clamped via Cinemachine
• Animation parameters (Speed, Walking) updated based on state

✅ Inventory System (Inventory.cs, PlayerInventory.cs)

• Modular, container-based design
• Server-authoritative item handling
• Drag-and-drop inventory UI implemented and functional

✅ Player Hotbar & Item Interaction (PlayerHotbar.cs)

• Server-authoritative hotbar system synchronized via NetworkVariable<int> for selected slot index
• Supports cycling through hotbar slots via scroll input and direct slot selection
• Uses Unity Input System callbacks registered only for the owning player
• Selected tool items can be used through input (e.g., attack action) with server RPC validation
• Item usage triggers gameplay effects on server and replicates visuals/effects to clients via client RPC
• Spawns item visuals in the player’s hand socket on all clients to represent the currently equipped tool
• Item usage logic is delegated to ItemUsageSO subclasses such as ResourceToolUsageSO (handles raycasting and resource node damage)
• Robust error and state checking with detailed debug logging using DLog

Networking Details

• Client inputs trigger server RPCs (UseItemServerRpc, SetSelectedIndexServerRpc) to ensure server authority
• The server validates and applies item usage effects before broadcasting visual feedback to all clients
• Item instance data is tracked and used to ensure proper contextual behavior (e.g., durability, unique IDs)
• Replicated visuals (spawned prefabs for equipped items) are controlled on clients to maintain sync and immersion
