Overview

This kinematic constraint keeps an objects up direction constant.

The Kinematic Gryoscopic Joint works without using any Kinematic Relations.

Where to find

The Kinematic Gyroscopic Joint can be found under Mechanics > Kinematics > Kinematic joints > Kinematic Gyroscopic Joint.

This will add the Kinematic 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 Body Controller in the hierarchy.

The following inspector component will be shown:

Feature layout

The image below shows the complete feature layout of the Kinematic 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.
Min Translation Delta	The minimum value the joint detects as a change in position.
Min Rotation Delta	The minimum value the joint detects as a change in rotation.
Kinematic Chaining
Show in Scene View	Shows chained connections of this object through arrows.
Show When Not Selected	If should show chaining if object is not selected.
Add Kinematic Transfer Relation	When a kinematic Body is dragged into this a transfer relation between them is created.
Opposing Kinematic Relation	The Kinematic Body which this relation is connected.
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.
Ratio	The ratio in which the relation is done (1 means all the applied rotation translation is equally transferred).
Invert Relation	If the relation is in inverted direction (so if rotating to right the connected object rotates to the left).
Gyroscopic Joint Settings
Global Up Direction	Describing the up direction of the Kinematic Gyroscopic Joint in global space.
Local Up Direction	Describing the up direction of the Kinematic Gyroscopic Joint in local space.
Scene View Settings
Always Enabled
Enabled in Scene View
Color Settings
Global Up Color	Color of the global up direction in scene view.
Local Up Color	Color of the local up direction in scene view.

How to use

Add a

Kinematic Gyroscopic Joint to an object.

Set the

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

Test if the joint is working.
