Member Function Documentation

◆ SetPredictionArea() [1/2]

void Quantum.Frame.SetPredictionArea	(	FPVector3	position,
		FP	radius
	)

inline

Set the prediction area.

Parameters

position	Center of the prediction area
radius	Radius of the prediction area

The Prediction Culling feature must be explicitly enabled in SimulationConfig.UsePredictionArea.

This can be safely called from the main-thread.

Prediction Culling allows developers to save CPU time in games where the player has only a partial view of the game scene. Quantum prediction and rollbacks, which are time consuming, will only run for important entities that are visible to the local player(s). Leaving anything outside that area to be simulated only once per tick with no rollbacks as soon as the inputs are confirmed from server. It is safe and simple to activate and, depending on the game, the performance difference can be quite large.Imagine a 30Hz game to constantly rollback ten ticks for every confirmed input (with more players, the predictor eventually misses at least for one of them). This requires the game simulation to be lightweight to be able to run at almost 300Hz(because of the rollbacks). With Prediction Culling enabled the full frames will be simulated at the expected 30Hz all the time while the much smaller prediction area is the only one running within the prediction buffer.

◆ SetPredictionArea() [2/2]

void Quantum.Frame.SetPredictionArea	(	FPVector2	position,
		FP	radius
	)

inline

See SetPredictionArea(FPVector3, FP).

Parameters

position
radius

◆ InPredictionArea() [1/2]

Boolean Quantum.Frame.InPredictionArea ( FPVector3 position )

inline

Test is a position is inside the prediction area.

Parameters

position Position

Returns: True if the position is inside the prediction area.

◆ InPredictionArea() [2/2]

Boolean Quantum.Frame.InPredictionArea ( FPVector2 position )

inline

See InPredictionArea(FPVector3).

Parameters

position

Returns

◆ Serialize() [1/2]

override Byte [] Quantum.Frame.Serialize ( DeterministicFrameSerializeMode mode )

inline

Serializes the frame using a temporary buffer (20MB).

Parameters

mode

Returns

◆ Serialize() [2/2]

ArraySegment<byte> Quantum.Frame.Serialize	(	DeterministicFrameSerializeMode	mode,
		byte[]	buffer,
		int	offset = `0`,
		bool	allocOutput = `false`
	)

inline

Serializes the frame using buffer as a buffer for temporary data.

If allocOutput is set to false, then buffer is also used for the final data - use offset and count from the result to access the part of buffer where serialized frame is stored.

If allocOutput is set to true then a new array is allocated for the result.

Despite accepting a buffer, this method still allocates a few small temporary objects. IAssetSerializer.SerializeAssets(System.Collections.Generic.IEnumerable<AssetObject>) is also going to allocate when serializing DynamicAssetDB, but how much depends on the serializer itself and the number of dynamic assets.

Parameters

mode
buffer
offset
allocOutput

Returns: Segment of buffer where the serialized frame is stored

Do not serialize during GameStart callback because systems have not been initialized, yet. Rather use CallbackSimulateFinished to wait for the first update.

inline

Dump the frame in human readable form into a string.

Returns: Frame representation

◆ CalculateChecksum() [1/2]

inline

◆ CalculateChecksum() [2/2]

UInt64 Quantum.Frame.CalculateChecksum ( bool useSharedSerializer )

inline

Calculates a checksum for the current game state.

Parameters

useSharedSerializer True - use shared checksum serializer to avoid allocs (not thread-safe).

Returns

inlineprotected

Copies the complete frame memory.

frame Input frame object
