Changing legacy recipes

Back to Home; see also Bridges.

Legacy recipes are ordinary modern recipes in a data pack (legacyconnector_legacy_recipes) placed below world data packs, so they are changed like any mod's recipes:

• Data packs: each recipe has a stable id, <mod>:<kind>/<output item> (<kind> is shaped, shapeless, smelting or custom; the output's namespace is added for another mod's item, _2, _3, ... for more recipes of one output), e.g. ic2:shaped/macerator or legacytest:shaped/minecraft/diamond. 1.12.2 recipes keep their registry name (<mod>:<name>_code); 1.12.2 smelting is legacyconnector:smelting_1122/<output item>. A file at the same path in a world data pack replaces the recipe; {"neoforge:conditions":[{"type":"neoforge:false"}]} removes it.
• KubeJS: event.remove({id: 'ic2:shaped/macerator'}), event.remove({mod: 'ic2'}), event.replaceInput(...) and so on work as for modern mods.
• MineTweaker 3 (1.7.10): the legacy jar loads and runs its scripts/*.zs against the legacy recipe lists; recipes.addShaped/addShapeless/remove and furnace.addRecipe/remove become modern recipes. MineTweaker runs its scripts when the server starts (after data packs loaded), so the data packs are reloaded once when a script changed the recipes; /minetweaker reload is picked up the same way within a few seconds. For 1.12.2, recipes removed from the legacy recipe registry or smelting list are left out the same way (CraftTweaker 1.12 itself is not tested yet).

KubeJS needs nothing else: what it (or a data pack) does to a legacy recipe also applies to the legacy crafting and smelting lookups that mod crafting tables, autocrafters and furnaces use (CraftingManager.findMatchingRecipe, FurnaceRecipes.getSmeltingResult): a removed recipe no longer crafts there, a changed one crafts as changed. Not yet: MineTweaker removing vanilla recipes (they are not in the legacy lists; remove them with a data pack or KubeJS), input filters and replaceInput on custom legacy recipe classes (legacyconnector:legacy_recipe: KubeJS sees their output, not their inputs; remove them by id or output and add a new recipe), and machine recipes kept in a mod's own API (IC2 macerator, Thermal pulverizer), which are not modern recipes.
