51-58: Consider clarifying the "unsure" comment.The type change looks good, but there's an uncertain comment about the apartment number field. Consider:
- Documenting the purpose of this field
- Adding validation if necessary
- Removing the comment once verified

39-76: Consider performance implications of List usage.The consistent change from
ICollectiontoListacross all methods suggests a deliberate choice. While this makes the API more specific, consider:
- If the caller needs to create new List instances just to call these methods
- If there are performance implications when dealing with large collections
A possible optimization would be to keep
ICollectionif random access isn't required, or document whyListis specifically needed.Maple2.Server.Game/PacketHandlers/LoadUgcMapHandler.cs (1)
81-86: Consider optimizing memory allocations and lock scope.While the thread-safety approach with the lock statement is correct, there are opportunities for optimization:
Consider applying these improvements:
private static void LoadPlots(GameSession session, List<PlotCube> plotCubes) { + // Acquire values under lock but process outside + IEnumerable<Plot> plots; lock (session.Field.Plots) { - List<Plot> allPlots = session.Field.Plots.Values.ToList(); - List<Plot> ownedPlots = allPlots.Where(x => x.State is not PlotState.Open).ToList(); - session.Send(LoadCubesPacket.PlotOwners(ownedPlots)); - session.Send(LoadCubesPacket.Load(plotCubes)); - session.Send(LoadCubesPacket.PlotState(allPlots)); - session.Send(LoadCubesPacket.PlotExpiry(ownedPlots)); + plots = session.Field.Plots.Values.ToList(); } + + // Process outside lock to minimize lock duration + var (allPlots, ownedPlots) = (plots.ToList(), plots.Where(x => x.State is not PlotState.Open).ToList()); + + // Send packets + session.Send(LoadCubesPacket.PlotOwners(ownedPlots)); + session.Send(LoadCubesPacket.Load(plotCubes)); + session.Send(LoadCubesPacket.PlotState(allPlots)); + session.Send(LoadCubesPacket.PlotExpiry(ownedPlots)); }This optimization:
- Minimizes the lock duration by only protecting the initial data access
- Reduces the number of allocations by reusing the initial enumeration
- Maintains the same functionality while being more performant
The current implementation is functionally correct, and these suggestions are purely for optimization.

65-74: Verify ExpiryTime initialization and handling.The changes look good, but let's ensure:
- ExpiryTime is properly initialized in the Plot class
- The value is in the correct time format expected by the client
✅ Verification successful
Based on the shell script results, I can now generate the final response as I have sufficient information about ExpiryTime handling across the codebase.
ExpiryTime handling is properly implemented and consistent.
The verification shows that:
- ExpiryTime is consistently handled as Unix timestamp (seconds since epoch) across the codebase
- The Plot class inherits ExpiryTime from the UgcMap model which is properly initialized and managed
- The value is correctly converted between DateTime and epoch seconds using extension methods (ToEpochSeconds/FromEpochSeconds)
- The time format is consistent with what the client expects as it's used in LoadCubes packet

39-43: Verify Plot model compatibility with PlotInfo.The change from
ICollection<PlotInfo>toList<Plot>looks good, but let's verify that thePlotclass contains all necessary fields previously accessed fromPlotInfo.✅ Verification successful
Let me try a different approach to verify the Plot class structure.
From the search results, I can now provide a definitive response:
The Plot class inherits from PlotInfo, maintaining full compatibility
The code shows that
Plotis a derived class ofPlotInfo:public class Plot(UgcMapGroup metadata) : PlotInfo(metadata)This inheritance relationship ensures that
Plothas all the necessary properties fromPlotInfo, including:
Number(from base class)PlotMode(from base class, which represents the state)The change from
ICollection<PlotInfo>toList<Plot>is safe as:
- All required properties are available through inheritance
Plotis more specific thanPlotInfo, adding plot-specific functionality likeCubesmanagement🏁 Scripts executed
