TODOs

1. Implement a way to have unique server name or a way to client know that which server is created by whom?
2. Prevent player joining if player try to join a session with max players.
3. Add free look with alt button, so prop can look around without disturbing hide position.

Major Issues And Fixes

1. Join session try to join on port 0 and connection timed out, only when I package the game and test, works fine in PIE.

   Fix: In AMenuGameMode class, the bUseSeamlessTravel was set to true, which should be only true when you are performing a travel from one map to another map in same server. But in this case the client was getting travel to a remote server, so it should be false.

2. NumOpenPublicConnection is not updating when player join or leave the session.

   Info: The NumOpenPublicConnection is part of FOnlineSession class that display number of availabel slots for player to join a server.

   Fix: Implemented RegisterPlayer() and UnregisterPlayer(). From AMenuGameMode::PostLogin() calling the RegisterPlayer() that in turn call the one from Subsystem class which internally updates the NumOpenPublicConnections.

3. Session disappear from SearchResult when NumOpenPublicConnections become 0.

4. When player changes the mesh, its kinda glitchy now. Happening after adding capsule and mesh location updates.

   Fix: SphereTraceSingle() was tracing the floor mesh and changing to it. Fixed by replacing to SphereTraceMulti() and checking if should changed to traced actor or not.

5. When host quit the game MenuGameMode::ReturnToMainMenuHost() send a reason to PlayerController::ClientReturnToMainMenuWithTextReason_Implementation(), but the reason is getting overrite by internal function calling it again.

6. Changing menu background image isn't working. Maybe: try sending image to GameInstance and then perform RPC to server so data persist and then try changing

7. Profile image cannot be replicated cuz of limit of 64 KB in TArray element size.

8. BestProp is not showing in the scoreboard.

notes (for future upgrade reference)

1. Can change texture LOD bias to reduce vram usage

2. remove lumen and use bakelight for low end system

3. disable reflections

4. remove TSR anti aliasing

5. disable shadows completely

6. set screen resolution to 50%, ugly graphics but better FPS

7. use culling, occulsion

8. Load client data in game instance before joining the session, then load data to server's game instance. Then, when travel to game map, again load data to server's game state
