name: AlignOrientation
type: class
memory_category: BaseParts
summary: |
  Constraint which applies torque to align two attachments, or to align one
  attachment with a goal orientation.
description: |
  The `AlignOrientation` constraint applies torque to align two attachments, or
  to align one attachment with a goal orientation. As indicated by the name, it
  only affects the **orientation** of the attachments, not their position (to
  align attachments **positionally**, see `Class.AlignPosition`).

  Torque created by `AlignOrientation` is applied about the center of mass of
  the parent of the attachments, or the center of mass of parts rigidly
  connected to the parents.

  When configuring this constraint, it may be helpful to study
  [Roblox Units](../../../physics/units.md) to understand how Roblox units
  compare to metric units.

  #### Affected Axes

  The axes affected by torque are controlled through the constraint's
  `Class.AlignOrientation.AlignType|AlignType` property. When set to
  `Enum.AlignType|PrimaryAxisParallel`,
  `Enum.AlignType|PrimaryAxisPerpendicular` or
  `Enum.AlignType|PrimaryAxisLookAt`, torque will only occur when the primary
  axes become misaligned. Otherwise, the constraint will apply torque about all
  3 axes to achieve alignment.

  #### Reactionary Torque

  By default, the constraint only applies torque to
  `Class.Constraint.Attachment0|Attachment0` while
  `Class.Constraint.Attachment1|Attachment1` remains unaffected. If desired,
  torque can be applied to both attachments in **equal and opposite directions**
  by enabling
  `Class.AlignOrientation.ReactionTorqueEnabled|ReactionTorqueEnabled`.

  #### Torque Magnitude

  You can configure this constraint to apply the maximum torque that constraints
  allow through the `Class.AlignOrientation.RigidityEnabled|RigidityEnabled`
  property. When `true`, the physics solver reacts as quickly as possible to
  complete the alignment. When `false`, the torque is determined by
  `Class.AlignOrientation.MaxTorque|MaxTorque`,
  `Class.AlignOrientation.MaxAngularVelocity|MaxAngularVelocity`, and
  `Class.AlignOrientation.Responsiveness|Responsiveness`.

  #### Attachment Mode

  This constraint can use either **one** or **two** attachments in calculating
  its goal. See `Class.AlignOrientation.Mode|Mode` for details.

      are `Enum.AlignType|AllAxes`, `Enum.AlignType|PrimaryAxisParallel`,
      `Enum.AlignType|PrimaryAxisPerpendicular`, and
      `Enum.AlignType|PrimaryAxisLookAt`. The constraint will attempt to
      maintain the specified relationship, as given by the `Enum.AlignType`, by
      applying torques onto the relevant axes.
