CommonLootModifiers

Holds a set of implementations of ILootModifier of common usage.

These can be used freely instead of rewriting the same code more than once. They are also guaranteed to behave correctly.

Importing the class

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.

Static Methods

add

Adds the given IItemStack to the drops.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript
Copy
// CommonLootModifiers.add(stack as IItemStack) as ILootModifier

CommonLootModifiers.add(<item:minecraft:cobblestone>);
ParameterTypeDescription
stackIItemStackThe stack to add
addAll

Adds all the given IItemStack to the drops.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript
Copy
// CommonLootModifiers.addAll(stacks as IItemStack[]) as ILootModifier

CommonLootModifiers.addAll(<item:minecraft:iron_ingot>, <item:minecraft:iron_nugget> * 5);
ParameterTypeDescription
stacksIItemStack[]The stacks to add
addAllWithBinomialBonus

Adds the given IItemStacks to the drops, modifying their count based on the level of the given
MCEnchantment on the tool used, if available.

In case no tool is used to obtain the stack, then this loot modifier behaves exactly like
this#addAll(IItemStack...).

The fortune modifier is applied separately for each IItemStack.

The formula used is based on the binomial_with_bonus_count formula used by vanilla. In this case, the
value of extra is added to the current tool's enchantment level; that determines the amount of times the
randomness will roll. Every roll that is higher than p will add one element to the stack. This is the
formula used by potatoes and carrots to determine their drop count.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript
Copy
// CommonLootModifiers.addAllWithBinomialBonus(enchantment as MCEnchantment, extra as int, p as float, stacks as IItemStack[]) as ILootModifier

CommonLootModifiers.addAllWithBinomialBonus(<enchantment:minecraft:fortune>, 3, 0.5714286, <item:minecraft:wheat_seeds>, <item:minecraft:carrot> * 9);
ParameterTypeDescription
enchantmentMCEnchantmentThe enchantment to check for.
extraintAn extra value that will be added to the tool's enchantment level.
pfloatThe probability of the binomial distribution, between 0.0 and 1.0 (both exclusive).
stacksIItemStack[]The stacks to add.
addAllWithChance

Adds the given MCWeightedItemStacks to the drops, according to the specified chances.

The chance will be computed on each modifier roll, and independently for each of the given stacks.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript
Copy
// CommonLootModifiers.addAllWithChance(stacks as MCWeightedItemStack[]) as ILootModifier

CommonLootModifiers.addAllWithChance(<item:minecraft:honey_bottle> % 50, <item:minecraft:dried_kelp> % 13);
ParameterTypeDescription
stacksMCWeightedItemStack[]The stacks to add.
addAllWithOreDropsBonus

Adds the given IItemStacks to the drops, modifying their count based on the level of the given
MCEnchantment on the tool used, if available.

In case no tool is used to obtain the stack, then this loot modifier behaves exactly like
this#addAll(IItemStack...).

The fortune modifier is applied separately for each IItemStack.

The formula used is based on the ore_drops formula used by vanilla, which multiplies the stack's
original count by a random number between 1 and the tool's enchantment level + 1. This is the formula used by
all vanilla ores to determine their drop count.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript
Copy
// CommonLootModifiers.addAllWithOreDropsBonus(enchantment as MCEnchantment, stacks as IItemStack[]) as ILootModifier

CommonLootModifiers.addAllWithOreDropsBonus(<enchantment:minecraft:fortune>, <item:minecraft:coal>, <item:minecraft:diamond>);
ParameterTypeDescription
enchantmentMCEnchantmentThe enchantment to check for.
stacksIItemStack[]The stacks to add.
addAllWithUniformBonus

Adds the given IItemStacks to the drops, modifying their count based on the level of the given
MCEnchantment on the tool used, if available.

In case no tool is used to obtain the stack, then this loot modifier behaves exactly like
this#addAll(IItemStack...).

The fortune modifier is applied separately for each IItemStack.

The formula used is based on the uniform_bonus_count formula used by vanilla. In this case, the
enchantment level is multiplied by multiplier and a random number is extracted between 0 and the result.
This number is then added to the original's stack count. This is the formula used by redstone ore and glowstone
to determine their drop count.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

The formula used is based on the binomial_with_bonus_count formula used by vanilla. In this case, the

remove

Removes every instance of the targeted IIngredient from the drops.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript

CommonLootModifiers.remove(<tag:items:minecraft:creeper_drop_music_discs>);
ParameterTypeDescription
targetIIngredientThe IIngredient to remove.
removeAll

Removes every instance of all the targeted IIngredients from the drops.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

replaceAllStacksWith

Replaces every instance of the targeted IItemStacks with the replacement IItemStacks,
proportionally.

As an example, if the loot drops 5 carrots and this loot modifier runs with 2 carrots as the key of a pair and 1
potato as the corresponding value, the loot will be modified to 2 potatoes and 1 carrot. This happens because
every 2-carrot stack will be actively replaced by a 1-potato stack, without exceptions.

This loot modifier acts differently than this#replaceAllWith(Map), where a simpler approach is used.

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

CommonLootModifiers.replaceAllStacksWith({ <item:minecraft:carrots> * 2 : <item:minecraft:potatoes> });
ParameterTypeDescription
replacementMapIItemStack[IItemStack]A map of key-value pairs dictating the target to replace along with their replacement.
replaceAllWith

Replaces every instance of the targeted IIngredients with their corresponding replacement
IItemStack.

In this case, a simple matching procedure is used, where every stack that matches the key of the pair is replaced
by the corresponding value, without considering stack size. If stack size is to be preserved, refer to
this#replaceAllStacksWith(Map).

Returns: An ILootModifier that carries out the operation.
Return Type: ILootModifier

ZenScript
Copy
// CommonLootModifiers.replaceAllWith(replacementMap as IItemStack[IIngredient]) as ILootModifier

proportionally.

As an example, if the loot drops 5 carrots and this loot modifier runs with 2 carrots as the target
and 1 potato as the replacement, the loot will be modified to 2 potatoes and 1 carrot. This happens
because every 2-carrot stack will be actively replaced by a 1-potato stack, without exceptions.

This loot modifier acts differently than this#replaceWith(IIngredient, IItemStack), where a simpler approach
is used.

Returns: An ILootModifier that carries out the operation.

replacementIItemStackThe replacement to use.
replaceWith
