Class BufferedLinearInterpolator<T>

Solves for incoming values that are jittered Partially solves for message loss. Unclamped lerping helps hide this, but not completely

Syntax

public abstract class BufferedLinearInterpolator<T>
    where T : struct

Type Parameters

Name	Description
T	The type of interpolated value

Fields

MaximumInterpolationTime

There's two factors affecting interpolation: buffering (set in NetworkManager's NetworkTimeSystem) and interpolation time, which is the amount of time it'll take to reach the target. This is to affect the second one.

Declaration

public float MaximumInterpolationTime

Field Value

Type	Description
Single

Methods

AddMeasurement(T, Double)

Add measurements to be used during interpolation. These will be buffered before being made available to be displayed as "latest value".

Declaration

public void AddMeasurement(T newMeasurement, double sentTime)

Parameters

Type	Name	Description
T	newMeasurement	The new measurement value to use
Double	sentTime	The time to record for measurement

Clear()

Resets interpolator to initial state

Declaration

public void Clear()

GetInterpolatedValue()

Gets latest value from the interpolator. This is updated every update as time goes by.

Declaration

public T GetInterpolatedValue()

Returns

Type	Description
T	The current interpolated value of type 'T'

Interpolate(T, T, Single)

Method to override and adapted to the generic type. This assumes interpolation for that value will be clamped.

Declaration

protected abstract T Interpolate(T start, T end, float time)

Parameters

Type	Name	Description
T	start	The start value (min)
T	end	The end value (max)
Single	time	The time value used to interpolate between start and end values (pos)

Returns

Type	Description
T	The interpolated value

InterpolateUnclamped(T, T, Single)

Method to override and adapted to the generic type. This assumes interpolation for that value will not be clamped.

Declaration

protected abstract T InterpolateUnclamped(T start, T end, float time)

Parameters

Type	Name	Description
T	start	The start value (min)
T	end	The end value (max)
Single	time	The time value used to interpolate between start and end values (pos)

Returns

Type	Description
T	The interpolated value

ResetTo(T, Double)

Teleports current interpolation value to targetValue.

Declaration

public void ResetTo(T targetValue, double serverTime)

Parameters

Type	Name	Description
T	targetValue	The target value to teleport instantly
Double	serverTime	The current server time

Update(Single, Double, Double)

Call to update the state of the interpolators before reading out

Declaration

public T Update(float deltaTime, double renderTime, double serverTime)

Parameters

Type	Name	Description
Single	deltaTime	time since last call
Double	renderTime	our current time
Double	serverTime	current server time

Returns

Type	Description
T	The newly interpolated value of type 'T'

Update(Single, NetworkTime)

Convenience version of 'Update' mainly for testing the reason we don't want to always call this version is so that on the calling side we can compute the renderTime once for the many things being interpolated (and the many interpolators per object)

Declaration

public T Update(float deltaTime, NetworkTime serverTime)

Parameters

Type	Name	Description
Single	deltaTime	time since call
NetworkTime	serverTime	current server time

Returns

Type	Description
T	The newly interpolated value of type 'T'
