To run a process continually while a VCI is present, use "**update**" function.

For the rotary movement, use **Quaternion.AngleAxis** to make the object rotate around the specified axis.\\
In this example, use **GetUp()** function to make the rotation around Y-axis.

Reference: Quaternion.AngleAxis\\
[[https://docs.unity3d.com/2018.4/Documentation/ScriptReference/Quaternion.AngleAxis.html]]

1. Create a new GameObject and create a Cube as its child.\\
In this example, we named the GameObject "Rotation_VCI", but it can be anything really.\\
Let's name the Cube "**Cube**." Specify Y-axis value of the Cube to 1 so that it doesn't go through the floor.

2. Attach the "**VCI Object**" component on the GameObject,\\
and attach the "**VCI SubItem**" component on the Cube.\\
When doing this, a "RigidBody" component is also attached automatically.\\
As we won't be using gravity, turn off **Use Gravity** and turn on **Is Kinematic**.

3. On the VCI Object component in the GameObject, set the Scripts Size as **1**.\\
Enter "main.lua" in the Name and paste the script shown below.

<file lua main.lua>
local cube = vci.assets.GetTransform("Cube")	--Insert the name of the SubItem as a string
local rotSpeed = 1	--Rotation speed

function updateAll()
    if cube.IsMine then  -- Called only when you have the ownership of the cube
	cube.SetLocalRotation(Quaternion.AngleAxis( rotSpeed, cube.GetUp() ) * cube.GetLocalRotation())
    end
end
</file>
