Configuring Recipe Logic

MBD2 21.1.1

Recipe logic connects one machine definition to one MBDRecipeType. It searches only when the machine has compatible handler proxies for recipe content.

Recipe logic points at a registered recipe type; its fuel configuration and viewer visibility belong to that type.

Settings

Setting	Runtime value key	Effect
Enable	recipe_logic.enable	Whether recipe logic runs at all
Recipe type	—	The registry ID this machine searches
Recipe damping value	recipe_logic.damping	Progress lost per waiting tick, floored at zero. 0 freezes progress while waiting
Consume inputs after working	recipe_logic.consume_inputs_after_working	Defer normal input consumption to completion. Every working tick re-simulates the inputs, and losing them interrupts the recipe
Always search recipe	recipe_logic.always_search	Force a fresh recipe-type search after each completed recipe instead of reusing the cached one
Always modify recipe	recipe_logic.always_modify	Re-apply modifiers every cycle. Needed when tier, upgrades or machine data can change the effective recipe between runs
Recipe modifiers	—	Amount, duration and parallel transformations applied to the matched recipe

Every keyed setting is also a runtime value, so a blueprint, a script or a UI can change it for one placed machine without touching the definition.

Wiring checklist

1. Register or export the recipe type before the machine definition is resolved.
2. Select its exact namespaced ID.
3. Add at least one handler trait for every capability used by candidate recipes.
4. Set handler IO for each recipe direction.
5. Test normal and per-tick content separately.
6. Add waiting and working states if the visuals should reflect status.
7. Test recipe-viewer lookup from the generated UI.

Conditions are evaluated again while working. A recipe may wait when weather, redstone, rotation, heat, pressure or another condition changes; waiting is not the same as resetting, and how much progress waiting costs is the damping value.

See Recipe lifecycle for the execution model, and Blueprints for rewriting a matched recipe rather than only scaling it.
