✨ What's New

🖥️ A complete new Player2NPC menu

Press H to open the new Player2NPC hub. The old character list screen has been replaced with an organized menu for managing your companions and the mod.

  • View your companions, their current tasks, inventory, and recent activity.
  • Edit companion prompts and manage who is allowed to talk to or control them.
  • Configure behavior, hunger, combat, travel, budgets, Joules, AI memory, profiles, and model settings.
  • Use dedicated screens for mod intelligence and automation settings.
  • Adjust crafting, smelting, mining, storage, fuel, and waypoint settings without digging through config files.

🌾 Farming overhaul

Companions can now build and manage proper farms from start to finish.

  • Set up a safe, irrigated 9x9 farm automatically or choose the exact location yourself.
  • Clear obstacles, fill gaps, place water, till the soil, and prepare the plot for planting.
  • Plant requested crops and quantities, gathering seeds and other needed items along the way.
  • Harvest only mature crops and collect the drops afterward.
  • Farms are remembered as waypoints so companions can find them again later.
  • Farm work can repair damaged plots and recover from temporary interruptions instead of losing the whole job.

You can use the direct commands setup_farm, plant_farm, and harvest_farm, or ask your companion naturally.

🛠️ Crafting, smelting, and upgrades

Item gathering and crafting have been rebuilt to handle longer jobs more reliably.

  • Companions can follow full recipe chains, gathering missing materials and crafting the intermediate parts they need.
  • Crafting works with a wider range of vanilla and modded recipes.
  • Nearby crafting tables are preferred, with a new table placed when one is needed and allowed.
  • Smelting and cooking now support furnaces, blast furnaces, and smokers.
  • Companions choose and gather suitable fuel, wait for the real cooking progress, and collect the finished items.
  • Item requests can now flow through gathering, crafting, and smelting as one job.
  • Smithing-table upgrades, including netherite upgrades, can resolve their required ingredients automatically.

Use smelt for furnace work and smith for smithing-table upgrades. Asking for an item with get can also make use of these steps when needed.

🧠 Long-term memory and better waypoints

Companions now have long-term memory that carries across conversations and play sessions.

  • Episodic memory helps the AI recall past interactions, conversations, and events instead of treating every chat as completely new.
  • Factual memory stores useful information about you, your companions, and the world, such as preferences, instructions, and important details you have shared.
  • Factual memories can be corrected when circumstances change, while episodic memories provide the history and context behind what the companion remembers.
  • Companions can also remember farm locations, inspect them later, and notice when a remembered waypoint has changed.
  • More companion state, including follow behavior, mood, hunger, and conversation data, is saved consistently between sessions.

Memory uses a small amount of Joules when it updates and searches its embedding-based memory. You do not need a large balance, but it is recommended to keep a small amount of Joules available if you want your companion to keep learning and recalling long-term memories.

🐛 Bug Fixes

  • Active jobs no longer disappear when a companion performs a small gesture; supported tasks can resume afterward.
  • Companions respect player-built structures more reliably and are less likely to break through walls just to reach a target.
  • Follow and food behavior no longer gets trapped in repeated break-off messages or confusing loops.
  • Companions keep picking up dropped items even when mobGriefing is turned off.
  • Traveling between dimensions no longer leaves duplicate copies of the same companion behind.
  • Fixed a rare crash that could happen when a companion collided with a mob.
