Handles the replacing of ingredients in recipes for various IRecipeManagers and WrapperRecipes.

Differently from various other mechanisms in CraftTweaker, each replacement that gets specified from within a Replacer doesn't get run immediately, rather it gets stored and all replacements are then applied together when the this#execute() method is called. This change is done so that multiple replacements can be performed at the same time, with a net gain on performance.Note that replacement must be explicitly supported by modded recipe types and managers, meaning that a Replacer may not be able to perform replacement on a certain set of recipes. If this is the case, a warning will be printed in the logs, so that you may review it.

Creating a Replacer gets done via the various forXxx methods, where Xxx identifies any suffix. Refer to the specific documentation to get more information on their behavior.

The various replace methods, listed both in this page and in other mod's possible expansions, then allow you to specify what should be the replacements that need to be carried out by the Replacer itself.

All recipes that get replaced by a Replacer get renamed according to a set naming scheme. You can modify completely by providing a lambda via this#useForRenaming(BiFunction), or just for a specific set of recipes via this#explicitlyRename(ResourceLocation, String).

An example usage of a Replacer could be Replacer.forTypes(craftingTable).replace(<item:minecraft:string>, <item:minecraft:diamond>).execute();

It might be required for you to import the package if you encounter any issues (like casting an Array), so better be safe than sorry and add the import at the very top of the file.

Name: forCustomRecipeSet

Creates a Replacer that will perform replacements only on the recipes whitelisted by the given function.

The first parameter of the predicate is a WrapperRecipe that indicates the recipe that is currently
being tested, whereas the second is the IRecipeManager that is responsible for handling that particular
type of recipes. The function should then return a boolean that either whitelists the recipe for replacement
(true) or blacklists it (false).

The given function must be a pure function, which means that the output must be the same
given the same set of inputs. In other words, you should not rely on external state for this function, since it
may be called multiple times on the same set of inputs in the same replacer run.

Returns: A new Replacer that uses the given function for whitelisting.
Return Type: Replacer

Name: replace

Replaces every match of the from IIngredient with the one given in to.

This replacement behavior is recursive, meaning that any IIngredient that gets found is looped recursively trying to identify matches. As an example, attempting to replace <item:minecraft:stone> with <item:minecraft:diamond> will perform this replacement even in compound ingredients, such as <item:minecraft:stone> | <item:minecraft:gold_ingot> or <tag:items:minecraft:stones> (supposing that minecraft:stones is a tag that contains minecraft:stone among other items).

If this behavior is not desired, refer to this#replaceFully(IIngredient, IIngredient) instead.

This method is a specialized by this#replace(IItemStack, IIngredient) for IItemStacks and should be preferred in these cases.

Returns: A Replacer that will carry out the specified operation.
Return Type: Replacer

ZenScript

Name: replace

Replaces every match of the from IItemStack with the one given in to.

This replacement behavior is recursive, meaning that any IIngredient that gets found is looped recursively trying to identify matches. As an example, attempting to replace <item:minecraft:stone> with <item:minecraft:diamond> will perform this replacement even in compound ingredients, such as <item:minecraft:stone> | <item:minecraft:gold_ingot> or <tag:items:minecraft:stones> (supposing that minecraft:stones is a tag that contains minecraft:stone among other items).

Link to g--19

Name: replaceFully

Replaces every instance of the target from IIngredient with the to one.

This replacement behavior is not recursive, meaning that the IIngredients will be matched closely instead of recursively. As an example, attempting to replace fully <item:minecraft:stone> will only replace ingredients that explicitly specify <item:minecraft:stone> as an input, while compound ingredients such as <item:minecraft:stone> | <item:minecraft:gold_ingot> won't be replaced.

If this behavior is not desired, refer to this#replace(IIngredient, IIngredient) instead.

Name: suppressWarnings

Suppresses warnings that arise when trying to replace unsupported recipes.

Additional warnings will not be suppressed. Note that it is suggested to keep this disabled while testing and enable it only if excluding the problematic recipes via this#excluding(ResourceLocation...) would prove to be too cumbersome.

Returns: A Replacer with replacement warnings suppressed.
Return Type: Replacer

Returns: A Replacer that will use the given function for renaming.
