[1.1.0] - 2025-05-07

Added

• R.E.P.O. Beta Compatibility:
  • Full support for R.E.P.O. Open Beta 0.1.2_22beta alongside stable 0.1.2.
  • Implemented dynamic game version detection (GameVersionSupport.cs) to correctly interface with different SteamManager.UnlockLobby() signatures (parameterless for stable, UnlockLobby(bool open) for beta). This ensures proper Steam lobby visibility control across game versions.
• Museum Map (Module) Support:
  • Introduced synchronization for Module components (LateJoinManager.SyncModuleConnectionStatesForPlayer).
  • Late joiners will now correctly see the connection states (Top, Bottom, Left, Right, First) of map modules, crucial for new maps like "Museum" that utilize this system. This is achieved by re-sending the ModuleConnectionSetRPC to the joining player.
  • Added reflection helpers for Module fields (SetupDone, ConnectingTop, etc.) in Utilities.cs.
• Early Lobby Locking Mechanism:
  • The game lobby is now locked earlier during level transitions initiated from the truck screen (e.g., when "Start Game" or "Return to Lobby with Loot" is confirmed).
  • This is achieved by new prefix patches on TruckScreenText.PlayerChatBoxStateLockedDestroySlackers and TruckScreenText.PlayerChatBoxStateLockedStartingTruck.
  • This proactive locking (EarlyLobbyLockHelper.TryLockLobby) prevents players from joining during potentially unstable mid-transition phases, before RunManager.ChangeLevel fully manages the lobby state.
• Lobby Unlock Failsafe:
  • Implemented a coroutine-based failsafe (Patches.LobbyUnlockFailsafeCoroutine) to ensure the game lobby unlocks if the intended mechanism (via GameDirector.SetStart) is prevented from running (e.g., due to another mod's interference).
  • If the lobby is meant to be open but remains locked after a timeout, the failsafe will force it open. This is armed during RunManager_ChangeLevelHook_Postfix and disarmed by GameDirector_SetStart_Postfix.
• Configurable Lobby Lock on Level Generation Failure:
  • Added a new configuration option: Lock Lobby On Level Generation Failure (Default: true) under the "Late Join Behavior" section.
  • When true (default), if a level reports a generation failure (and doesn't transition to the Arena), the lobby will be locked, preventing late joins.
  • When false, if a modded level reports a generation failure but the game continues (i.e., doesn't crash to Arena), L.A.T.E. will still evaluate normal scene-based join rules (Shop, Truck, Level) as if the failure didn't occur. This can be useful for modded levels that might incorrectly flag a failure but still load. This setting does not affect true failures that lead to the Arena scene.

Changed

• Enhanced Hinge/Door Synchronization:
  • Improved synchronization for PhysGrabHinge objects (e.g., doors, lockers, cabinets).
  • In addition to the existing broken state sync (HingeBreakRPC), the mod now also syncs the open/closed state for late joiners using the PhysGrabHinge.closed field and OpenImpulseRPC. (Ref: DestructionManager.SyncHingeStatesForPlayer)
  • This provides a more consistent visual and interactive state for these objects.
• Lobby Open/Close Logic Refinement:
  • The Patches.ShouldAllowLobbyJoin logic now uses direct RunManager level instance comparisons (e.g., runManager.levelCurrent == runManager.levelArena) instead of relying solely on SemiFunc helper methods. This offers more precise control over lobby joinability based on the current scene, especially during level transitions.
  • GameDirector.SetStart (postfix patch) is now the definitive point for unlocking the lobby after level generation and loading, if conditions permit. It also handles disarming the new lobby unlock failsafe.
• Mod Incompatibility Documentation:
  • Updated README.md to reflect successful testing and support for R.E.P.O. 0.1.2_22beta.
  • Added new known mod incompatibilities to README.md:
    • FastStartup
    • Imperium_Repo (due to patching LevelAnimationCompleted)

Fixed

• Resolved BerserkerEnemies Incompatibility: Addressed a previous incompatibility with BerserkerEnemies that could cause issues with level generation completion hooks (e.g., preventing L.A.T.E.'s GameDirector.SetStart postfix from running).
  • This was fixed by adjusting Harmony patch execution order, specifically by applying [HarmonyPriority(Priority.Last)] to L.A.T.E.'s GameDirector_SetStart_Postfix and PlayerAvatar_LoadingLevelAnimationCompletedRPC_Prefix patches.
  • This ensures L.A.T.E.'s critical lobby management and synchronization logic executes after potentially conflicting modifications from other mods that hook into the same game methods.

[1.0.0] - 2025-05-05

Initial Release

Added

• Core functionality allowing players to join games already in progress (Late Joining).
• Host-Only operation: Mod logic runs entirely on the host.
• Configuration options (BepInEx/config/LATE.cfg):
  • Enable/disable joining in Shop, Truck, Level, Arena scenes.
  • Option to re-kill players who died before leaving/rejoining the same level instance (Kill If Previously Dead).
  • Option to spawn rejoining players at their last known position or death head (Spawn At Last Position).
  • Advanced option to force a level reload for everyone on late join (Force Level Reload on Late Join).
  • Configurable log level for debugging (Log Level).
• Comprehensive state synchronization for late joiners:
  • Level state (RunManager: level name, completion status, game over).
  • Level generation completion (LevelGenerator).
  • Extraction Point state (ExtractionPoint: state, goal fetched, current goal value, surplus value, shop status, active/inactive status).
  • Valuable Objects (ValuableObject: current dollar value).
  • Shop Items (ItemAttributes: current value).
  • Player Death Status (PlayerStateManager, PlayerAvatar.PlayerDeathRPC).
  • Truck Screen (TruckScreenText: initialization, current page).
  • Prop Switch setup trigger (ValuableDirector).
  • Destroyed Physics Objects (PhysGrabObject.DestroyPhysGrabObjectRPC).
  • Destroyed Impact Objects (PhysGrabObjectImpactDetector.DestroyObjectRPC).
  • Broken Hinges (PhysGrabHinge.DestroyHingeRPC, HingeBreakRPC).
  • Item States via specific RPCs:
    • ItemToggle: ToggleItemRPC (On/Off), ToggleDisableRPC (Interactable).
    • ItemBattery: BatteryFullPercentChangeRPC.
    • ItemMine: StateSetRPC.
    • ItemMelee: MeleeBreakRPC, MeleeFixRPC.
    • ItemDrone: ButtonToggleRPC.
    • ItemHealthPack: UsedRPC.
    • ItemGrenade: TickStartRPC.
    • ItemTracker: SetTargetRPC.
  • Enemy synchronization:
    • Spawn/Despawn status via EnemyParent (SpawnRPC, DespawnRPC).
    • Target Player View ID (Enemy.TargetPlayerViewID, UpdatePlayerTargetRPC, etc.).
    • Frozen status (Enemy.FreezeRPC).
    • Specific states/targets for numerous enemy types (Animal, Bang, Beamer, etc. - see README for full list).
    • Notifies enemies when players join (PlayerAdded) or leave (PlayerRemoved).
  • Arena-specific state (Arena): DestroyCrownCageRPC, CrownGrabRPC (Winner), PlayerKilledRPC (Pedestal Count).
  • Voice chat state initialization (VoiceManager, PlayerAvatar.UpdateMyPlayerVoiceChat).
• Player Position Tracking (PlayerPositionManager) for Spawn At Last Position feature.
• Patching Mechanisms:
  • Uses HarmonyLib (Attribute and Explicit patches) and MonoMod Hooks.
  • Patches NetworkManager, RunManager, PlayerAvatar, PhysGrabObject, PhysGrabObjectImpactDetector, PhysGrabHinge, EnemyVision, EnemyTriggerAttack, NetworkConnect, GameDirector.
• Utilities class (Utilities) for caching reflected members and helper functions.
• Fix for potential EnemyVision dictionary errors when late joiners trigger vision/attacks.
• Forces PhotonNetwork.AutomaticallySyncScene = true early for joining clients via NetworkConnect patch.
• Extraction Point Item Resync: Teleports items in the EP out and back to force clients to re-evaluate their state (addresses potential value desync).
