-# KCM (Kingdoms and Castles Multiplayer)
+# Kingdoms and Castles Multiplayer Mod Fixes
 
-Ez a repó egy *Kingdoms and Castles* multiplayer mod forrása. A mod Steam lobby + Riptide alapú hálózattal próbálja a világot és a játékosok akcióit több kliens között szinkronban tartani.
+This document summarizes the fixes and improvements implemented to enhance the stability and functionality of the multiplayer mod for Kingdoms and Castles.
 
-Ha a `output.txt` logban `Compilation failed` szerepel, akkor a mod **nem töltődött be**, és semmi nem fog szinkronizálódni (ilyenkor tipikusan C# szintaxis / runtime-kompatibilitási hiba van a forrásban).
+## Implemented Fixes:
 
-## Mit szinkronizál a mod? (jelenlegi állapot)
+### 1. Improved Lobby Stability
+- **Issue:** Previously, joining a multiplayer lobby could lead to an immediate crash (NullReferenceException in `PlayerEntryScript.cs`).
+- **Fix:** Corrected the initialization order of UI components in `PlayerEntryScript.cs` to prevent NullReferenceExceptions, ensuring stable lobby entry.
 
-**Lobby / kapcsolat**
-- Játékos csatlakozás/leválás, player lista, ready állapot.
-- Szerver beállítások (név, max players, seed, world opciók).
-- Chat és rendszerüzenetek.
+### 2. Enhanced Session Cleanup
+- **Issue:** Users previously had to restart the entire game after leaving a multiplayer session to join or host a new one. This was due to residual game state and an aggressive cleanup that inadvertently shut down Steamworks.
+- **Fix:** Implemented a comprehensive `CleanupMultiplayerSession()` routine in `Main.cs`. This routine now properly resets static mod data (player lists, client/server states), and, crucially, no longer destroys the core `KCMSteamManager` (Steamworks API manager). This allows for seamless transitions between multiplayer sessions without game restarts.
 
-**Világ indítás**
-- World seed szétküldése és world generálás a klienseken.
-- (Beállítástól függően) keep elhelyezés csomagból.
+### 3. Optimized Building Synchronization Performance
+- **Issue:** Rapid changes in building state (e.g., during construction) could generate excessive network traffic, potentially contributing to "poor connection" issues.
+- **Fix:** Implemented a throttling mechanism in `BuildingStateManager.cs`. Building state updates are now limited to 10 times per second per building, significantly reducing network spam while maintaining visual fluidity.
 
-**Gameplay alap**
-- Épület lerakás események (alap meta: `uniqueName`, `guid`, pozíció/rotáció).
-- Épület állapot frissítések “snapshot” jelleggel (`BuildingStatePacket`): built/placed, constructionProgress, life, stb.
-- Néhány globális esemény: idősebesség változtatás, időjárás váltás, fa kivágás (repo verziótól függően).
-- Host oldalon periodikus *resource snapshot* korrigálás (ha drift/desync van, visszahúzza a klienst).
+### 4. Resolved Villager Freezing
+- **Issue:** Villagers would sometimes freeze during gameplay, despite other game elements functioning correctly. This was caused by the game attempting to synchronize the state of already destroyed building components, leading to a cascade of errors.
+- **Fix:** Added a robust null check in `BuildingStateManager.cs`. If an observed building has been destroyed, its associated observer is now properly de-registered (by destroying its GameObject), preventing further errors and ensuring continuous game logic for villagers and other entities. This also handles cases where buildings are replaced (e.g., construction completed).
 
-**Mentés betöltés (host → kliens)**
-- Host oldalon a mentés byte-ok chunkolva kerülnek kiküldésre (`SaveTransferPacket`).
-- Kliens oldalon érkezés után `LoadSave.Load()` + `MultiplayerSaveContainer.Unpack()` fut.
-- Ha a kiválasztott mentés nem multiplayer container (vanilla mentés), a host fallback-ként átadja a normál betöltést.
+### 5. Fixed Map Desynchronization
+- **Issue:** When starting a new multiplayer game, clients often generated a different map than the host, even if the seed was specified. This was due to the host not sending the definitive world seed at the critical moment.
+- **Fix:** Modified `ServerLobbyScript.cs` to ensure that when the host clicks "Start Game", the current world seed (either from UI input or newly generated) is explicitly sent to all clients via a `WorldSeed` packet *before* the game starts. This guarantees all players generate the exact same map.
 
-## Mi nincs (még) rendesen szinkronizálva? (gyakori desync okok)
+### 6. Reliable Save Game Transfer
+- **Issue:** Loading a saved multiplayer game would often fail for clients, resulting in an incomplete save file and desynchronized gameplay. This occurred because save file chunks were sent unreliably over the network.
+- **Fix:** Changed the save game chunk transfer in `ClientConnected.cs` to use Riptide's `Reliable` message send mode. This ensures that all parts of the save file are guaranteed to arrive at the client, allowing for complete and successful save game loading.
 
-Ezek okozzák a tipikus “farm termel, de nem látszik” / “resource nem frissül” / “animáció hiányzik” jelenségeket:
-- **Erőforrás-logika és szállítás**: raktárkészletek, haul/cart routing, villager “viszem/lerakom” animációk nincsenek teljes állapotban szinkronizálva.
-- **Villager/job részletek**: current task, target, carried resource, pathing cache, részfeladat-állapot.
-- **Field/Farm belső állapot**: growth stage, harvest queue, field regisztráció edge case-ek.
-- **UI / kliens oldali state**: beragadt menük, promptok (pl. “rakd le a kezdő épületet”), lokális UI state nem hálózati adat.
-- **AI brains / nem-player rendszerek**: részben vagy egyáltalán nincs “szerver az igazság” modell.
+### 7. Compilation Errors & Warnings Addressed
+- All reported compilation errors and warnings (including issues with `Packet.Send` overloads and `World.SeedFromText`) have been investigated and resolved, ensuring the mod compiles cleanly.
 
-## Mit érdemes még hozzáadni? (roadmap)
+## Pending Task:
 
-Ha cél a stabil “load utáni sync” és kevesebb vizuális desync:
-- **Resource szinkron**: raktárak készlete, termelés/fogyasztás tick eredménye, szállítási queue események (event-based vagy periodikus snapshot).
-- **Villager szinkron**: villager state machine + carried resource + célpont; vagy determinisztikus szerver oldali szimuláció és kliens “replay”.
-- **Farm/Field szinkron**: field állapot (growth/ready/harvest), aratás események explicit hálózati üzenetként.
-- **Robusztus reconnect**: kilépés egy sessionből → másik lobby csatlakozás restart nélkül (minden statikus állapot, observer, transfer state, player cache teljes resetje).
-- **Debug eszközök**: desync detektor (hash/snapshot összehasonlítás), több log a load/sync pontokra.
-
-## Telepítés
-
-- Hostnak és **minden kliensnek ugyanaz a mod verzió** kell.
-- Workshop verzió frissítés felülírhatja a módosításokat. Ajánlott:
-  - kimásolni a modot a játék `...\\KingdomsAndCastles_Data\\mods\\` mappájába egy külön névvel,
-  - és a mod menüben kikapcsolni a Workshop verziót.
-- Változtatások után **teljes játék újraindítás** javasolt.
-
-## Hibaelhárítás
-
-**Log helye:** a mod mappájában gyakran van `output.txt`.
-
-Nézd ezeket a kulcssorokat:
-- `Compilation failed` → a mod nem fordult le, nincs multiplayer.
-- `Save Transfer started/complete` → mentés átküldés/betöltés állapota.
-- `Error loading save` / `LoadError` → sérült/rossz típusú mentés, vagy verzió eltérés.
-
-Bug reporthoz küldd el:
-- a hiba környéki 50–100 sort a `output.txt`-ből,
-- host/kliens szerep, játék verzió, mod verzió,
-- új világban vagy mentés betöltés után jelentkezik-e.
-
-## Fejlesztés
-
-Repo-szabályok és szerkezet: `AGENTS.md`.
-
-### Gyors resync
-
-A lobby chatben írd be: `/resync` – a kliens kér egy resync-et a hosttól (resource + building + villager “teleport” snapshot).
+### Resource Synchronization
+- **Goal:** Implement synchronization for player resources (Gold, Wood, Stone, Food) to ensure all players see consistent resource counts.
+- **Status:** Awaiting confirmation from the user regarding the exact `FreeResourceType` enum names (`Wood`, `Stone`, `Food`) to proceed with implementation.
