Methods

Perpendicular

Calculates the perpendicular vector to the current vector.

Vector:Perpendicular()

Returns - Vector The perpendicular vector

IsParallelTo

Checks if the current vector is parallel to the given vector.

Vector:IsParallelTo(vector)

Parameters

  • vector
    Vector
    The vector to compare with

Returns - boolean True if the vectors are parallel, false otherwise

Slerp

Spherical linear interpolation between the calling vector and the target vector over t = [0, 1].

Vector:Slerp(target, t)

Parameters

  • target
    Vector
    The target vector to interpolate towards
  • t
    number
    The interpolation factor, ranging from 0 to 1

Returns - Vector The resulting vector after spherical linear interpolation

LocalTranslate

Translates a vector within a local coordinate system.

This function computes a new vector by applying an offset relative to the local axes defined by the forward, right, and up direction vectors.

                - `offset.x`: Translation along the forward vector

                - `offset.y`: Translation along the right vector

                - `offset.z`: Translation along the up vector

Vector:LocalTranslate(offset, forward, right, up)

Parameters

  • offset
    Vector
    The translation offset vector. This defines how much to move along the forward, right, and up directions
  • forward
    Vector
    The forward direction of the local coordinate system
  • right
    Vector
    The right direction of the local coordinate system
  • up
    Vector
    The up direction of the local coordinate system

Returns - Vector A new vector representing the translated position

AngleDiff

Calculates the angle difference in degrees between the calling vector and the given vector. This is always the smallest angle.

Vector:AngleDiff(vector)

Parameters

  • vector
    Vector
    The vector to calculate the angle difference with

Returns - number Angle difference in degrees

SignedAngleDiff

Calculates the signed angle difference between the calling vector and the given vector around the specified axis.

Vector:SignedAngleDiff(vector, axis)

Parameters

  • vector
    Vector
    The vector to calculate the angle difference with
  • axis (optional)
    Vector
    The axis of rotation around which the angle difference is calculated

Returns - number The signed angle difference in degrees

Unpack

Unpacks the x, y, z components as 3 return values.

Vector:Unpack()

Returns

  • number

x component

  • number

y component

  • number

z component

LengthSquared

Returns the squared length (magnitude) of the vector.

More efficient than calculating the actual length as it avoids using sqrt().

Vector:LengthSquared()

Returns - number

IsSimilarTo

Checks if this vector is similar to another vector within a given tolerance.

Vector:IsSimilarTo(vector, tolerance)

Parameters

  • vector
    Vector
    The vector to compare against
  • tolerance (optional)
    number
    The tolerance within which the vectors are considered similar. Default is 1e-5

Returns - boolean Returns true if the vectors are similar within the tolerance, otherwise false

Clone

Creates a copy of the vector.

Vector:Clone()

Returns - Vector A new vector with the same components as the original
