ItemPredicate

Represents the predicate for an MCItemDefinition.

This predicate will match an item against either a specific MCItemDefinition or item tag (MCTag<T>), with the second taking precedence over the first. If this initial check succeeds, then the predicate may also verify additional item properties, such as its current amount, its damage, or internal NBT data via NBTPredicate. The predicate can also check the enchantments that are currently either applied to or stored onto the item via EnchantmentPredicates, or the potion effect that is currently present on the item, if any.

By default, any item will be able to pass the checks of this predicate.

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.

matchNbtbooleanWhether to consider the NBT data or not when matching the stack.
withDataPredicate

Creates and sets the NBTPredicate that will be matched against the item's NBT data.

Any changes that have already been made to the NBT predicate will be overwritten, effectively replacing the previous one, if any.

Return Type: ItemPredicate

ItemPredicate.withDataPredicate(builder as Consumer<NBTPredicate>) as ItemPredicate
ParameterTypeDescription
constructeurConsumer<NBTPredicate>A consumer that will be used to configure the NBTPredicate.
withEnchantmentPredicate

Creates and adds a new EnchantmentPredicate to the list of predicates to match against the item's enchantments.

The added predicate is simply added to the list. No validity checks are performed, meaning that there may be multiple predicates that target a single enchantment. In this case, they all need to match, thus they have to have compatible bounds.

Return Type: ItemPredicate

ItemPredicate.withEnchantmentPredicate(builder as Consumer<EnchantmentPredicate>) as ItemPredicate
ParameterTypeDescription
constructeurConsumer<EnchantmentPredicate>A consumer that will be used to configure the EnchantmentPredicate.
withEnchantmentPredicate

Creates and adds a new EnchantmentPredicate for the given MCEnchantment to the list of predicates to match against the item's enchantments.

The predicate that will be configured is already configured to target the specified enchantment.

The added predicate is simply added to the list. No validity checks are performed, meaning that there may be multiple predicates that target a single enchantment. In this case, they all need to match, thus they have to have compatible bounds.

Return Type: ItemPredicate

ItemPredicate.withEnchantmentPredicate(enchantment as MCEnchantment, builder as Consumer<EnchantmentPredicate>) as ItemPredicate
ParameterTypeDescription
enchantmentMCEnchantmentThe enchantment that should be checked.
constructeurConsumer<EnchantmentPredicate>A consumer that will be used to configure the EnchantmentPredicate.
withExactAmount

Sets the amount to exactly match the given value.

If the amount had already some bounds specified, then they will be overwritten with the new value.

Return Type: ItemPredicate

ItemPredicate.withExactAmount(value as int) as ItemPredicate
ParameterTypeDescription
valueintThe exact value the amount should be.
withExactDamage

Sets the damage to exactly match the given value.

If the damage had already some bounds specified, then they will be overwritten with the new value.

Return Type: ItemPredicate

ItemPredicate.withExactDamage(value as int) as ItemPredicate
ParameterTypeDescription
valueintThe exact value the damage should be.
withItem

Sets the MCItemDefinition that this predicate should match.

If a tag to match against has already been set, then the tag check will take precedence over this check.

Return Type: ItemPredicate

ItemPredicate.withItem(definition as MCItemDefinition) as ItemPredicate
ParameterTypeDescription
definitionMCItemDefinitionThe item the predicate should match.
withItem

Sets the MCItemDefinition that this predicate should match to the one contained in the given IItemStack.

If a tag to match against has already been set, then the tag check will take precedence over this check.

Return Type: ItemPredicate

ItemPredicate.withItem(itemStack as IItemStack) as ItemPredicate
ParameterTypeDescription
format@@0 itemStackIItemStackThe stack containing the item that the predicate should match.
withMaximumAmount

Sets the maximum amount of items to max.

If the amount had already some bounds specified, then the maximum value of the bound will be overwritten with the value specified in max. On the other hand, if the amount didn't have any bounds set, the maximum is set, leaving the lower end unbounded.

The maximum value is inclusive, meaning that a value that is equal to max will pass the check.

Return Type: ItemPredicate

ItemPredicate.withMaximumAmount(max as int) as ItemPredicate
ParameterTypeDescription
maxintThe maximum value the amount should be.
withMaximumDamage

Sets the maximum damage of the item to max.

If the damage had already some bounds specified, then the maximum value of the bound will be overwritten with the value specified in max. On the other hand, if the damage didn't have any bounds set, the maximum is set, leaving the lower end unbounded.

The maximum value is inclusive, meaning that a value that is equal to max will pass the check.

Return Type: ItemPredicate

ItemPredicate.withMaximumDamage(max as int) as ItemPredicate
ParameterTypeDescription
maxintThe maximum value the damage should be.
withMinimumAmount

Sets the minimum amount of items to min.

If the amount had already some bounds specified, then the minimum value of the bound will be overwritten with the value specified in min. On the other hand, if the amount didn't have any bounds set, the minimum is set, leaving the upper end unbounded.

The minimum value is inclusive, meaning that a value that is equal to min will pass the check.

Return Type: ItemPredicate

ItemPredicate.withMinimumAmount(min as int) as ItemPredicate

ParameterTypeDescription
minintThe minimum value the damage should be.
withPotion

Sets the potion effect that should be present on the target item.

Return Type: ItemPredicate

ParameterTypeDescription
minintThe minimum value the damage should be.
maxintThe maximum value the damage should be.
withStoredEnchantmentPredicate

Creates and adds a new EnchantmentPredicate to the list of predicates to match against the item's stored enchantments.

The added predicate is simply added to the list. No validity checks are performed, meaning that there may be multiple predicates that target a single enchantment. In this case, they all need to match, thus they have to have compatible bounds.

Return Type: ItemPredicate

ItemPredicate.withStoredEnchantmentPredicate(builder as Consumer<EnchantmentPredicate>) as ItemPredicate
ParameterTypeDescription
constructeurConsumer<EnchantmentPredicate>A consumer that will be used to configure the EnchantmentPredicate.
