Class CapabilityDispatcher

java.lang.Object

net.minecraftforge.common.capabilities.CapabilityDispatcher

All Implemented Interfaces:

ICapabilityProvider, INBTSerializable<CompoundTag>

@ParametersAreNonnullByDefault
public final class CapabilityDispatcher
extends Object
implements INBTSerializable<CompoundTag>, ICapabilityProvider

A high-speed implementation of a capability delegator. This is used to wrap the results of the AttachCapabilitiesEvent. It is HIGHLY recommended that you DO NOT use this approach unless you MUST delegate to multiple providers instead just implement y our handlers using normal if statements. Internally the handlers are baked into arrays for fast iteration. The ResourceLocations will be used for the NBT Key when serializing.

Method Details

getCapability

public <T> LazyOptional<T> getCapability(Capability<T> cap,
 @Nullable
 Direction side)

Description copied from interface: ICapabilityProvider

Retrieves the Optional handler for the capability requested on the specific side. The return value CAN be the same for multiple faces. Modders are encouraged to cache this value, using the listener capabilities of the Optional to be notified if the requested capability get lost.

Parameters:

cap - The capability to check

side - The Side to check from, CAN BE NULL. Null is defined to represent 'internal' or 'self'

Returns:

The requested an optional holding the requested capability.
