====== Rigidbody (UnityComponent) ======
Rigidbody is required to enable physical behavior of an object (drop by gravity, collision, etc.).

  * [[https://docs.unity3d.com/ja/current/Manual/class-Rigidbody.html |Rigidbody Unity manual]]

==== Summary of Colliders in VCI ====

  * For information on the synchronization of physics, refer to [[en:vci:component:sdk:subitem:owned| Relation between ownership and synchronization of SubItem]]
  * The extent of influence by Rigidbody is also determined by [[en:vci:component:sdk:subitem:groupid|GroupID of SubItem]].
  * Required to use onCollision function of [[en:vci:script:reference:eventfunction|VCI event functions]].

==== Properties ====

^ Property ^ Feature^
| **Use Gravity** | When enabled, **the object will be affected by the gravity and fall** |
| **Is Kinematic** | When enabled, **the object will not be moved with physics engine**.\\ However, you can still move the object by controlling Transform directly.\\|
| Mass | Mass of the object (Kg) |
| Drag | How much air resistance affects the object when moving from forces |
| Angular Drag | How much air resistance affects the object when rotating from torque |
| Interpolate | Not used in VCI. |
| Collision Detection | Used to prevent fast moving objects from passing through other objects |
| Constraints Freeze Position | Limits the movement. The object does not move in the checked axis |
| Constraints Freeze Rotation | Limits the movement. The object does not rotate in the checked axis |

To freeze a VCI in the air, disable "Use Gravity" and enable "Is Kinematic".\\
