Core

Core is a community made Fortnite gameserver focused on recreating original behavior as accurately as possible across our current supported Fortnite builds. We prioritize fixing reported issues and completing functionality for supported versions over expanding version support. When work begins on a new Fortnite version, we aim to make it fully functional before moving on to another version.

Core runs inside Fortnite to provide server-side systems to load maps, apply playlists, accept players, run matches, and support gameplay. This repository does NOT include Fortnite game files, a launcher, or backend services.

Core is an independent community project. It is not affiliated with, endorsed by, or supported by Epic Games.

Please refer to the Contributing section before posting an issue, Thank you!

Version support

Fortnite version	Status
1.7.2–6.00	Full support ✅
6.01+	Unsupported ⚠️

• Full support means that a version is actively supported. We prioritize fixes and missing functionality for fully supported versions before adding support for other versions.
• Unsupported means the build may start and have some gameplay features, but it may be unfinished, untested, or have gamebreaking bugs.
• Save the World is experimental and unfinished. Expect missing or incomplete mission, inventory, quest, AI, and progression behavior.

When reporting a problem refer to the Contributing section.

Building

Requirements

• Windows 10 or Windows 11
• Visual Studio 2022 or 2026
• Desktop development with C++ workload
• MSVC v143 C++ x64/x86 build tools
• Windows 10 SDK

Build steps

1. Clone the repository:

   git clone https://github.com/PongooDev/Core
   
   cd Core
   

2. Open Core.sln in Visual Studio

3. Select Release and x64 in the solution toolbar.

4. Build it

Server config options

Core reads configuration from the Fortnite process command line during startup. Boolean options are enabled by including their name as a command-line flag.

Option	Default	Purpose
Playlist=<id-or-name>	2	Selects an Athena playlist by numeric ID or internal object name.
MapToLoad=<map>	automatic	Overrides Core's default map selection.
-bIsProd	off	Enables production behavior and disables Core's custom development commands.
-bEnableClientConsole	off	Allows Core's console window when running in client mode.
-bIsClient	off	Runs Core's client initialization path instead of the gameserver path.
-bSetClientLogVerbosity	off	Applies Core's log-verbosity setup in client mode.
-bUseGameSessions	off	Uses the game-session validation and assignment path.
-bSkipSessionValidation	off	Skips session validation when game sessions are enabled.
-bListenServer	off	Uses Core's listen-server path instead of dedicated-server setup.
-bDevSameTeam	off	Places players on the same development team.

Example:

Playlist=Playlist_DefaultSolo -bUseGameSessions

Core logs the resolved configuration at startup. Check the console or Server_log.txt to confirm that the intended values were received.

These are developer focused options. Some combinations are version-specific or experimental.

Playlist selection

Playlist= accepts either:

• a numeric playlist ID, such as Playlist=2; or
• an internal playlist name, such as Playlist=Playlist_DefaultSolo.

Playlist names and availability differ by Fortnite build. If a playlist cannot be found, double check the internal name in the game assets or in an object dump.

Commands

When -bIsProd isn't enabled, Core extends Fortnite's ServerCheat path with development and testing commands.

Core supports positional arguments and named parameters:

cheat GiveItem WID_Assault_Auto_Athena_R_Ore_T03 1
cheat GiveItem?ItemDefinitionName=WID_Assault_Auto_Athena_R_Ore_T03?Count=1

Current command groups include:

Category	Commands
Items and ammo	GiveItem, ForceGiveItem, SpawnPickup, SetLoadedAmmo, GiveAmmo, ClearEquippedItem, GetWeaponStats, ServerExecuteInventoryItem, DumpInventory
Player state	SetHealth, SetMaxHealth, SetShield, SetMaxShield, SetKillScore, TeleportToLocation, DumpCurrentLocation
Pawns and bots	DumpAllPawns, PossessPawnByIndex, PossessPawnByName, DespawnAllBots
World and actors	SpawnActor, DumpActorsWithClass, DumpAircrafts, DestroyTarget, StartEvent
QuickBars	SpawnQuickBars, DestroyQuickBars, DumpQuickBars
Testing and fun	LootRain, SetGameSpeed, TeleportAllToMe, SwapPlaces, LaunchPawn, SetScale, ScalePawn, Goto, DestroyBuildings, EmoteAll, EmoteAllSpecific, EmotePlayerByName, TogglePersonalVehicle
AFortAthenaMutator_Heist	SetSpawnExitCraftTime, DumpExitCraftTimer, HeistPhaseStep, DumpGameState, UpdateGamePhaseStep, SpawnExitCraft

Run cheat Help in game for all commands, syntax, and descriptions.

Troubleshooting

The project does not build

• Confirm Release | x64 is selected.
• Build from Core.sln
• Look at the actual compiler errors near the end of the output, the project can have many warnings.

A feature works on one build but not another

Core functions differently on every version. Reference the next section about making an issue report.

Contributing

Contributions are welcome, whether it is code or an issue report.

Issue reports

Include all of the following in a report if possible:

1. Fortnite version and CL
2. Playlist
3. Number of players
4. Reproduction steps
5. Screenshots
6. Server log
7. Core commit
8. Anything else that may help

Issues that are overly broad, contain only a crash log without context, or provide too little information to accurately show or reproduce the problem may be closed until the required details are supplied.

Code

Before submitting code:

1. Keep unrelated fixes in separate pull requests
2. Keep your code clean and readable. You may create helper functions if needed for better readability.
3. Test your code and include the versions you tested it on.
4. Necessary or helpful logging is encouraged however remove excessive or temporary logging from the final change.
5. Avoid broad version gates unless the compatibility boundary is understood and supported by testing or other evidence.

Pull requests may be declined when they are inaccurate, untested, overly broad, unrelated to the reported issue, or harmful to other supported versions.
