TFC Desire Paths

This mod introduces realistic pathways to the TerraFirmaCraft world that form naturally from the constant movement of players and animals. Animal behavior can be customized to your preferences. The block transformation system works through simple recipes in datapacks, allowing you to add your own surface change rules.

By default, grass transforms into corresponding soil types. During rain, dirt has a chance to compact and turn into mud when characters or animals walk on it. If the player is sneaking, paths won't form, while running accelerates their appearance.

New Vegetation Mechanics

The mod adds a dynamic grass growth system based on lighting conditions. In dark areas, such as deep forests, grass gradually disappears, exposing the soil. With sufficient light, it regenerates to full coverage. This creates more natural undergrowth and may help discover clay or peat deposits. (feature is configurable, enabled by default)

Configuration via Datapacks

Recipe example for version 1.20.1:

{
  "type": "tfcdesirepaths:compact",
  "ingredient": "tfc:dirt/loam",
  "result": "tfc:mud/loam",
  "mud": true,
  "chance": 80
}

The mud parameter activates transformation only during rain, while chance determines the success probability (1 out of the specified number).
