name: CylindricalConstraint
type: class
memory_category: BaseParts
summary: |
Constrains two attachments on two parts to have a relative linear and
rotational motion.
description: |
A **CylindricalConstraint** allows its attachments to slide along one axis and
rotate about another axis. It can be thought of like a combination of a
`Class.PrismaticConstraint` and a `Class.HingeConstraint`. The sliding axis is
determined by the **X** axis of the constraint's
`Class.Constraint.Attachment0|Attachment0`. The rotation axis is centered at
the constraint's `Class.Constraint.Attachment1|Attachment1` and is angled off
of the sliding constraint by the constraint's
`Class.CylindricalConstraint.InclinationAngle|InclinationAngle`.
This constraint, along with a `Class.SpringConstraint`, is ideal for building
vehicle suspension.
Note that if this constraint attaches one part (**A**) to another part (**B**)
that is anchored or connected to an anchored part (**Z**), part **A** will not
be locally simulated when interacting with a player.
When configuring this constraint, it may be helpful to study
[Roblox Units](../../../physics/units.md) to understand how Roblox units
compare to metric units.
#### Angular Power
If a cylindrical's
`Class.CylindricalConstraint.AngularActuatorType|AngularActuatorType` is set
to `Enum.ActuatorType|Motor`, it attempts to rotate the attachments with the
goal of reaching its
`Class.CylindricalConstraint.AngularVelocity|AngularVelocity`. You can further
control this rotation through both
`Class.CylindricalConstraint.MotorMaxAngularAcceleration|MotorMaxAngularAcceleration`
and `Class.CylindricalConstraint.MotorMaxTorque|MotorMaxTorque`. If a
cylindrical's
`Class.CylindricalConstraint.AngularActuatorType|AngularActuatorType` is set
to `Enum.ActuatorType|Servo`, it attempts to rotate to an angle specified by
`Class.CylindricalConstraint.TargetAngle|TargetAngle`. This rotation is
controlled by `Class.CylindricalConstraint.AngularSpeed|AngularSpeed`,
`Class.CylindricalConstraint.AngularResponsiveness|AngularResponsiveness`, and
`Class.CylindricalConstraint.ServoMaxTorque|ServoMaxTorque`.
#### Linear Power
If a cylindrical's `Class.CylindricalConstraint|ActuatorType` is set to
`Enum.ActuatorType|Motor`, it attempts to translate the attachments with the
goal of reaching `Class.CylindricalConstraint|Velocity`. You can further
control this translation through both
`Class.CylindricalConstraint|MotorMaxAcceleration` and
`Class.CylindricalConstraint|MotorMaxForce`. If a cylindrical's
`Class.CylindricalConstraint|ActuatorType` is set to
`Enum.ActuatorType|Servo`, it attempts to translate the attachments to a set
separation specified by `Class.CylindricalConstraint|TargetPosition`. This
translation is controlled by `Class.CylindricalConstraint|Speed`,
`Class.CylindricalConstraint|LinearResponsiveness`, and
`Class.CylindricalConstraint|ServoMaxForce`.
#### Limits
You can set limits to restrict both the **sliding range** and **rotation** of
a cylindrical constraint. Enabling the
`Class.CylindricalConstraint|LimitsEnabled` property exposes the
`Class.CylindricalConstraint|LowerLimit` and
`Class.CylindricalConstraint|UpperLimit` values, as well as
`Class.CylindricalConstraint|Restitution` which defines the elasticity of the
attachments when they reach either limit. Enabling the
`Class.CylindricalConstraint.AngularLimitsEnabled|AngularLimitsEnabled`
property exposes the `Class.CylindricalConstraint.LowerAngle|LowerAngle` and
`Class.CylindricalConstraint.UpperAngle|UpperAngle` limits, as well as
`Class.CylindricalConstraint.AngularRestitution|AngularRestitution` which
defines the elasticity of the attachments when they reach either limit.
#### Inclination Angle
`Class.CylindricalConstraint.InclinationAngle|InclinationAngle` defines the
direction of the rotation axis as an angle from the **X** axis in the **XY**
plane of `Class.Constraint.Attachment0|Attachment0`, from
-180 to 180. This lets you tilt the rotating element without
changing the sliding axis.

This property specifies the sharpness of the angular servo motor in
reaching the `Class.CylindricalConstraint.TargetAngle|TargetAngle`, when
`Class.CylindricalConstraint.AngularActuatorType|AngularActuatorType` is
set to `Enum.ActuatorType|Servo`. Larger values correspond to a faster
response and smaller values results in more damping and a slower response.
