# OvrNodeLinker

### Description

This Node is used to link [OvrNodes](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) together. 

* Linking [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) one to another
* Linking an [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) to/from a list of [OvrNodes](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) contained in a GameObject
* Linking an [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) to/from a list of [OvrNodes](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) contained in a GameObject created from  [OvrInstantiate](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/gameobject-interactions/ovrinstantiate.md)

These are chosen via [ActionType ](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/utility/ovrnodelinker/ovrnodelinkeractiontype.md)parameter.

{% hint style="info" %}
**Note**: The behavior of the link depends on the interaction between each node. By default, the [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) "To Link" will be added to the PreExecutionNodes list of the [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) "Where Link". Sometimes it will instead be associated with the main execution of the target node.
{% endhint %}

### Link to Node

The **OvrNodeToLink** will be linked to the **OvrNodeWhereLink**.

#### 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)

### Link GameObject

In this mode, depending on the selected [OvrNodeLinkType](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/utility/ovrnodelinker/ovrnodelinktype.md), an [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) will be linked to a list of [OvrNodes](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) identified by their Node Id inside a GameObject. Or, alternatively, a list of [OvrNodes](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md) identified by their Node Id inside a GameObject will be linked to an [OvrNode](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/ovrnode.md).

### Link to Instantiate Game Object

This mode is very similar to [Link to GameObject](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/utility/ovrnodelinker/ovrnodelinkeractiontype.md), the only exception is that the target GameObject is not an object already present in the scene, but a product of a [OvrInstantiate](/over-sdk-manual/ovr-component-system-ancient-legacy/nodes/gameobject-interactions/ovrinstantiate.md) Node, which produces the object required for linking.
