#HytaleSP
An alternative launcher for "Hytale" with a fairly streightforward "native" UI
features:
- Multiple version management
- Incremental patch from one version to another
- Universal "online fix" or that works on all versions;
- Access all "Supporter" and "Cursebreaker" cosmetic items.
- Play local or online multiplayer
- Completely standalone; a single executable- no butler or other external tools.
- Fairly transparent online patch implementation.
- Run offline and download without needing a hytale account.
- Supports Windows 7+
Currently for: Windows and Linux (i would do MacOS, but i dont have access to an ARM Mac right now.)
NOTE: you can even probably play online, but only if the servers your joining have ``--auth-mode=insecure`` set in the command line;
enabling this option would also mean anyone using the offical launcher cannot play
because it doesn't allow insecure auth type outside singleplayer offline mode; .. for some reason
also if you use the "online play" feature in singleplayer should also work as long as other users also use hytLauncher ...
## Project layout
hytServer.go - hytale authentication server emulator "online fix"
hytAuth.go - implementation of hytale OAuth2.0, currently not used
hytFormats.go - most of the JSON structures used by hytale are here;
hytClient.go - downloading versions, etc
patch.go - itch.io's 'apply patch' wharf code
jwt.go - JSON structures used in hytale auth tokens
locations.go - default / location resolvers for many folders
Aurora/ - c code for the dll or shared object, loaded with the game,
that replaces account-data.hytale.com with a custom server ..
# Building
on windows, you first have to build the "Aurora.dll" using MSVC,
and then you can use ``go build .``
or you can ``build-windows.bat`` within the VS2026 developer command prompt to do this;
on linux, you need ``build-essential`` and then you can build "Aurora.so" using its Makefile;
after that you can use ``go build .``
or you can use ``build-linux.sh``
# Alternative names
Originally, i called it "hytLauncher", being a play on "TLauncher" for minecraft;
however i found that, alot of other alternative hytale launchers had a simular name, (eg HyTaLauncher, HyLauncher, etc.)
furthermore tLauncher is a bit sketchy in general and there are better options for minecraft too;
for now i have settled on "HytaleSP" .. a reference to an extremely OG minecraft launcher;
i may consider other names in the future;
other names i considered using :
- hyTLauncher
- HytaleSP
- AnjoCaidos Hytale Launcher
- HytaleForFree.com
in all seriousness i kind of would want something a bit original xS
also this is not nessecarily planned to be a purely 'offline mode' launcher;
i also want to add "premium" support as well-
mm the code for authentication flow is actually already here ..
but i wont remove the 'offline' or 'fakeonline' options for those who need them though ..
