About this project
What does Simple Update Checker add?
Simple Update Checker
Simple Update Checker is a small mod that adds in-game notification about Modrinth modpack update being available.
It works for both servers and clients.
The update information is displayed in logs on server/client boot and then in other places depending on where it runs.
For clients, it displays update info on main screen (on right side from modpack name/version text), refreshing every hour after
the game starts.
For servers, it displays it in logs after server starts and for operators on join. After that, it will check it every 12 hours
until update is found, after which it will repeat it after double time from last message, up to 14 days of delay
(12 hours, 1 day, 2 days, 4 days, 8 days, 14 days).
The check can also be triggered manually with /simpleupdatechecker check command, with limitation of 15 minutes per refresh.
All the checks can be disabled in simpleupdatechecker_user.json config or via /simpleupdatechecker settings command.
Configuration (User)
You can change settings via /simpleupdatechecker settings <name> <value> or within config. Both use same names.
You can find the config file in config/simpleupdatechecker_user.json and reload it with /simpleupdatechecker reload command.
