# repeatForever(_:)

Creates an action that repeats another action forever.

```
class func repeatForever(_ action: SCNAction) -> SCNAction
```

## Parameters

`action`

The action to execute.

## Return Value

A new action object.

## Discussion

When the action executes, the associated action runs to completion and then repeats.

This action is reversible; it creates a new action that is the reverse of the specified action and then repeats it forever.

> Note:
> The action to be repeated must have a non-instantaneous duration.
