(table)path (optional)—The name of a path object to be set as parent. (string)order (optional)—The order index to set for the control point in the new parentanimation. (number)RotationRotation is an Animation that automatically applies an affine rotation to the regionbeing animated. You can set the origin around which the rotation is being done, andthe angle of rotation in either degrees or radians.Rotation animations have no effect on FontStrings.Rotation has all the methods from Animation, plus the following:GetDegreesReturns the animation’s rotation amount (in degrees).degrees = Rotation:GetDegrees()Returns:degrees—Amount by which the region rotates over the animation’s duration(in degrees; positive values for counter-clockwise rotation, negative for clockwise)(number)GetOriginReturns the rotation animation’s origin point.point, xOffset, yOffset = Rotation:GetOrigin()During a rotation animation, the origin point remains in place while thepositions of all other points in the scaled region are moved according to therotation amount.Returns:point—Anchor point for the rotation origin (string, anchorPoint)xOffset—Horizontal distance from the anchor point to the rotation origin (inpixels) (number)yOffset—Vertical distance from the anchor point to the rotation origin (in pixels)(number)GetRadiansReturns the animation’s rotation amount (in radians).radians = Rotation:GetRadians()
