On Ancient Ground-Core
Mod written for the On Ancient Ground modpack to add essential content.
About this Mod
On Ancient Ground - Core
This mod adds custom and integration content for the On Ancient Ground modpack. Which is a 1.21 modpack based around TerraFirmaCraft (TFC) and Pastel.
This mod is open source with the hope that its code can help others make mods, especially for addons or modpacks centered around TerraFirmaCraft.
Important Note
Keep in mind that no datapack or resource pack assets are in the mod as of now, all of these assets are in the modpack the mod is written for. Many of these will be moved to this mod as Kubejs datagen is being dropped in favor for Java.
Keep in mind that as the associated modpack is released and playtested bugs may come up. Please report these on Github or Discord (see bar to the side, or top on mobile for links).
