# CylindricalConstraint

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 PrismaticConstraint and a HingeConstraint. The sliding axis is determined by the X axis of the constraint's Constraint.Attachment0. The rotation axis is centered at the constraint's Constraint.Attachment1 and is angled off of the sliding constraint by the constraint's CylindricalConstraint.InclinationAngle.

This constraint, along with a 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.

## Summary

### Properties

Type of angular actuator: None, Motor, or Servo.

Enables the angular limits around the rotation axis.

## Properties

### AngularResponsiveness

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

### AngularSpeed

Target angular speed. This value is unsigned as the servo will always move toward its target. In radians per second. Value in [0, inf).

### AngularVelocity

The target angular velocity of the motor in radians per second around the rotation axis. Value in [0, inf).

### CurrentAngle

Signed angle (in degrees) between the reference axis and the secondary axis of Attachment1 around the rotation axis. Value in [-180, 180].

### InclinationAngle

Direction of the rotation axis as an angle from the x-axis in the xy-plane of Attachment0. Value in [-180, 180].

### LowerAngle

Lower limit for the angle (in degrees) between the reference axis and the SecondaryAxis of Attachment1 around the rotation axis. Value in [-180, 180].

### MotorMaxAngularAcceleration

The maximum angular acceleration of the motor in radians per second squared. Value in [0, inf).

### MotorMaxTorque

The maximum torque the motor can apply to achieve the target angular velocity. The units are mass * studs^2 / second^2. Value in [0, inf).

### ServoMaxTorque

Maximum torque the servo motor can apply. The units are mass * studs^2 / second^2. Value in [0, inf).

### TargetAngle

Target angle (in degrees) between the reference axis and the secondary axis of Attachment1 around the rotation axis. Value in [-180, 180].

### UpperAngle

Upper limit for the angle (in degrees) between the reference axis and the SecondaryAxis of Attachment1 around the rotation axis. Value in [-180, 180].
