Member Function Documentation

Clamp()

static float LinearAlgebra.Angle.Clamp ( float  angle, float  min, float  max  )

static

Clamp the angle between the given min and max values.

Parameters

angle	The angle to clamp
min	The minimum angle
max	The maximum angle

Returns

The clamped angle

Angles are normalized

Difference()

static float LinearAlgebra.Angle.Difference ( float  a, float  b  )

static

Determine the angle difference, result is a normalized angle.

Parameters

a	First first angle
b	The second angle

Returns

the angle between the two angles

Angle values should be degrees

Normalize()

static float LinearAlgebra.Angle.Normalize ( float  angle )

static

Normalize an angle to the range -180 < angle <= 180.

Parameters

angle

The angle to normalize

Returns

The normalized angle in interval (-180..180]

Angle values should be in degrees

MoveTowards()

static float LinearAlgebra.Angle.MoveTowards ( float  fromAngle, float  toAngle, float  maxAngle  )

static

Rotate from one angle to the other with a maximum degrees.

Parameters

fromAngle	Starting angle
toAngle	Target angle
maxAngle	Maximum angle to rotate

Returns

The resulting angle

This function is compatible with radian and degrees angles

ToFactor()

static float LinearAlgebra.Angle.ToFactor ( Vector2  v1, Vector2  v2  )

static

Map interval of angles between vectors [0..Pi] to interval [0..1].

Parameters

v1	The first vector
v2	The second vector

Returns

The resulting factor in interval [0..1]

Vectors a and b must be normalized
