CFrame

CFrame, short for coordinate frame, is a data type that describes a 3D position and orientation. It is made up of a positional component and a rotational component. It includes essential arithmetic operations for working with 3D data on BrickVerse.

local cf = CFrame.new(0, 5, 0) * CFrame.Angles(math.rad(45), 0, 0)

Components

Positional

The positional component is available as a Vector3 in the Position property. In addition, the components of a CFrame’s position are also available in the X, Y and Z properties like a Vector3. A CFrame placed at a specific position without any rotation can be constructed using CFrame.new(Vector3) or CFrame.new(X, Y, Z).

Rotational

CFrame stores 3D rotation data in a 3-by-3 rotation matrix. These values are returned by the CFrame:GetComponents function after the X, Y and Z positional values. This matrix is used internally when doing calculations involving rotations. They use radians as their unit (for conversion to degrees, use math.rad/math.deg).

The matrix below represents the components of a CFrame’s rotation matrix and their relationship with the various vector properties available (LookVector, RightVector, etc). Although the individual components of the rotation matrix are rarely useful by themselves, the vector properties which derive from them are much more useful.

XVector	R00	R01	R02
YVector	R10	R11	R12
ZVector	R20	R21	R22

Constructors

CFrame.new ( )
Creates a blank identity CFrame.

CFrame.new ( Vector3 pos )
Returns a CFrame with no rotation with the position of the provided Vector3.

CFrame.new ( number x, number y, number z )
Creates a CFrame from position (x, y, z).

CFrame.new ( number x, number y, number z, number qX, number qY, number qZ, number qW )
Creates a CFrame from position (x, y, z) and quaternion (qX, qY, qZ, qW).

CFrame.new ( number x, number y, number z, number R00, number R01, number R02, number R10, number R11, number R12, number R20, number R21, number R22 )
Creates a CFrame from position (x, y, z) with an orientation specified by the rotation matrix [[R00 R01 R02] [R10 R11 R12] [R20 R21 R22]].

CFrame.lookAt ( Vector3 at, Vector3 lookAt, Vector3 up = Vector3.new(0, 1, 0) )
Creates a new CFrame located at at and facing towards lookAt, optionally specifying the upward direction (by default, (0, 1, 0)). This function replaces the CFrame.new(Vector3, Vector3) constructor (see above) which accomplished a similar task. This function allows you to specify the up Vector, using the same default as the old constructor.

CFrame.fromEulerAnglesXYZ ( number rx, number ry, number rz )
Creates a rotated CFrame using angles (rx, ry, rz) in radians. Rotations are applied in Z, Y, X order.

CFrame.fromEulerAnglesYXZ ( number rx, number ry, number rz )
Creates a rotated CFrame using angles (rx, ry, rz) in radians. Rotations are applied in Y, X, Z order.

CFrame.Angles ( number rx, number ry, number rz )
Equivalent to fromEulerAnglesXYZ.

CFrame.fromOrientation ( number rx, number ry, number rz )
Equivalent to fromEulerAnglesYXZ.

CFrame.fromAxisAngle ( Vector3 v, number r )
Creates a rotated CFrame from a Unit Vector3 and a rotation in radians.

CFrame.fromMatrix ( Vector3 pos, Vector3 vX, Vector3 vY, Vector3 vZ )
Creates a CFrame from a translation and the columns of a rotation matrix. If vz is excluded, the third column is calculated as [vx:Cross(vy).Unit].

CFrame.Orthonormalize ( )
Returns an orthonormalized copy of the CFrame. The BasePart.CFrame property automatically applies orthonormalization, but other APIs which take CFrames do not, so this method will occasionally be necessary when when incrementally updating a CFrame and using it with them
