component

<T> CustomItemDefinition.Builder component(ItemDataComponent<T> component,
 T value)

Sets data components that determine the item behavior. These are assumed to also be present server-side on the Java server. See CustomItemDefinition.components() for more information.

Added data components cannot be removed using removeComponent(Identifier), and this method will throw when a component is added that was removed using the aforementioned method.

Type Parameters:

T - the value held by the component

Parameters:

component - the type of the component, found in JavaItemDataComponents

value - the value of the component

Returns:

this builder

Throws:

IllegalArgumentException - when the added component was removed using removeComponent(Identifier)

Since:

2.9.3

component

default <T> CustomItemDefinition.Builder component(ItemDataComponent<T> component,
 GenericBuilder<T> builder)

Convenience method for component(ItemDataComponent, Object)

Type Parameters:

T - the value held by the component

Parameters:

component - the type of the component - found in JavaItemDataComponents

builder - the builder of the component

Returns:

this builder

Throws:

IllegalArgumentException - when the added component was removed using removeComponent(Identifier)

Since:

2.9.3

• component(ItemDataComponent, Object)

removeComponent

CustomItemDefinition.Builder removeComponent(Identifier component)

Indicates a removed item component that will not be present on the custom item despite existing on the vanilla item. This must match server-side behavior, otherwise, issues will occur. See CustomItemDefinition.removedComponents() for more information.

Removed data components cannot be added again using component(ItemDataComponent, Object), and this method will throw when a component is removed that was added using the aforementioned method.

Parameters:

component - the identifier of the vanilla base component to remove

Convenience method for removeComponent(Identifier).

Parameters:

component - the component type to remove

build

CustomItemDefinition build()

Creates the custom item definition.

Specified by:

build in interface GenericBuilder<CustomItemDefinition>

Returns:

the new custom item definition
