3 Feature layout
4 How to use

Overview

This kinematic constraint keeps an objects up direction constant.

The Gryoscopic Joint works without using any Kinematic Relations

Where to find

The Gyroscopic Joint can be found under Mechanics > Add Kinematics > Gyroscopic Joint.

This will add the Gyroscopic Joint component to the currently selected object or create a new empty GameObject with the component attached if no objects are selected.

Joints must be placed as children of a Kinematics Controller in the hierarchy.

The following inspector component will be shown:

Feature layout

The image below shows the complete feature layout of the Gyroscopic Joint component.

Generic Joint Settings
Pass Priority	Priority of the kinematic chain calculations. Higher numbers are calculated earlier
Enforce Outside Playmode	Enforces the joint to work in edit mode
Prevent Kinematic Update	Removes the joint from the kinematic chain calculations
Prevent Further Kinematic Update on this GameObject	Allows lower priority kinematic transforms on the same GameObject to be skipped in calculations
Allow Direct User Input	Allows the user to manipulate the joint with the scene gizmo
Min. User Input Translation Offset	The minimum value the user must input before translations are applied
Min. User Input Rotation Offset	The minimum value the user must input before rotations are applied
Kinematic Chaining
Create new Leading Transform Relation	Creates a new leading relation between Transforms
Create new Trailing Transform Relation	Creates a new trailing relation between Transforms Trailing Transforms are obsolete and will be removed in the near future
Opposing Relation Instance	The kinematic transform you want to link the joint to
Relation Direction	Describes the direction of the manipulation of the Transforms. The following options are available: BIDIRECTIONAL: Allows for both kinematic transforms, when they are being manipulated, to manipulate each other equally RECIEVE_ONLY: Allows for the joint, when it is being manipulated, to manipulate the opposing kinematic transform, but not the other way around SEND_ONLY: Allows for the opposing kinematic transform, when it is being manipulated, to manipulate the joint, but not the other way around
Relation Type	Used when two different sized Wheel Joints need the same rotational speed. The following options are available: TRANSLATION: Translates the transforms using the Wheel Radius ROTATION: Translates the transforms without using the Wheel Radius
Motion Direction is Reversed	When enabled, the manipulation to/from the opposing kinematic transform is inverted
Global Up Direction
Global Up Direction	A Scene Vector describing the up direction of the Gyroscopic Joint

How to use

1. Add a Gyroscopic Joint to an object

2. Set the Global Up Direction to your desired value and enable Enforce Outside Playmode

3. Test if the joint is working
