Syntax

static FVector RandomUnitVectorInEllipticalConeInRadiansFromStream
(
    const FVector & ConeDir,
    float MaxYawInRadians,
    float MaxPitchInRadians,
    const FRandomStream & Stream
)

Remarks

Returns a random vector with length of 1, within the specified cone, with uniform random distribution. The shape of the cone can be modified according to the yaw and pitch angles.

Parameters

Parameter	Description
MaxYawInRadians	The yaw angle of the cone (from ConeDir to horizontal edge), in radians.
MaxPitchInRadians	The pitch angle of the cone (from ConeDir to vertical edge), in radians.
Stream	The random stream from which to obtain the vector.
