# OvrRandom

Subclass of Ovr.OvrNode

### Description

This node is used to generate random values, based on the type of variable the user needs.

By changing the [OvrVariableType](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrvariable/ovrvariabletype.md), the requirements to get the random value change as well.

Attributes

{% hint style="info" %}
**Note**: the following attributes are added to the existing ones from the super class [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md)
{% endhint %}

### Random Number

In order to generate a random number ([OvrInt](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrint.md) or [OvrFloat](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrfloat.md)), the user needs to provide the node with a maximum and minimum value. The result will be stored in a numeric variable.

### Random Vector

There are several ways to generate a new [OvrVector2](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrvector2.md) or [OvrVector3](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrvector3.md):

* Like for random numbers, between Min and Max Vectors;
* Inside a Unity Circle \[[OvrVector2](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrvector2.md)] or Sphere \[[OvrVector3](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrvector3.md)], by calculating a random Vector inside a sphere with radius 1, then scaled up using Min and Max values.
* On the surface of a Unit Sphere \[OvrVector3 only], by calculating a random Vector on the surface of a sphere with radius 1, then scaled up using Min and Max values.

Attributes are very similar to those above.

### Random Rotation

To generate a new Rotation ([OvrQuaternion](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/variables/ovrnumericvariable/ovrquaternion.md)), the user can either:

* Generate a simple random Rotation;
* Generate a random Rotation with uniform distribution
