Syntax

static float K2_CalculateVelocityFromPositionHistory
(
    float DeltaSeconds,
    FVector Position,
    FPositionHistory & History,
    int32 NumberOfSamples,
    float VelocityMin,
    float VelocityMax
)

Remarks

This function calculates the velocity of a position changing over time. You need to hook up a valid PositionHistory variable to this for storage.

Parameters

Parameter	Description
DeltaSeconds	The time passed in seconds
Position	The position to track over time.
History	The history to use for storage.
NumberOfSamples	The number of samples to use for the history. The higher the number of samples - the smoother the velocity changes.
VelocityMin	The minimum velocity to use for normalization (if both min and max are set to 0, normalization is turned off)
VelocityMax	The maximum velocity to use for normalization (if both min and max are set to 0, normalization is turned off)
