public struct SnapshotDataBufferComponentLookup

Remarks

The helper only allows you to read component data. Buffers are not supported.

Methods

GetFallbackPredictionMode(in GhostSpawnBuffer)

Retrieve the prediction mode used as fallback if the spawning ghost has not been classified.

Declaration

public GhostSpawnBuffer.Type GetFallbackPredictionMode(in GhostSpawnBuffer ghost)

Parameters

Type	Name	Description

Type	Description
int	the id of the player owning the ghost, if the GhostOwner is present, 0 otherwise.

HasBuffer<T>(int)

Check if the a component of type T is present in this spawning ghost.

Declaration

public bool HasBuffer<T>(int ghostTypeIndex) where T : unmanaged, IBufferElementData

Parameters

Returns

Type	Description
bool	Whether the component is present in this spawning ghost.

Type Parameters

Name	Description
T	Component type in spawning ghost.

Remarks

This work for both IComponentData and IBufferElementData

HasGhostOwner(in GhostSpawnBuffer)

Declaration

public bool HasGhostOwner(in GhostSpawnBuffer ghost)

Parameters

Type	Name	Description
GhostSpawnBuffer	ghost	The spawning ghost

Returns

Type	Description
bool	True if the spawning ghost is owner predicted

IsOwnerPredicted(in GhostSpawnBuffer)

Check if the spawning ghost mode is owner predicted.

Declaration

public bool IsOwnerPredicted(in GhostSpawnBuffer ghost)

Parameters

Type	Name	Description
GhostSpawnBuffer	ghost	The spawning ghost

Returns

Type	Description
bool	True if the spawning ghost is owner predicted

TryGetComponentDataFromSnapshotHistory<T>(int, in DynamicBuffer<SnapshotDataBuffer>, out T, int)

Try to retrieve the data for a component type T from the the snapshot history buffer.

Declaration

public bool TryGetComponentDataFromSnapshotHistory<T>(int ghostTypeIndex, in DynamicBuffer<SnapshotDataBuffer> snapshotBuffer, out T componentData, int slotIndex = 0) where T : unmanaged, IComponentData

Parameters

Type	Name	Description
int	ghostTypeIndex	The index in the GhostCollectionPrefabSerializer collection.
DynamicBuffer<SnapshotDataBuffer>	snapshotBuffer	The entity snapshot history buffer.
T	componentData	The deserialized component data.
int	slotIndex	The slot in the history buffer to use.

Returns

Type	Description
bool	True if the component is present and the component data is initialized. False otherwise

Type Parameters

Name	Description
T	Component type

Remarks

Buffers aren't supported. Only components present on the root entity can be retrieved. Trying to get data for components in a child entity is not supported.
