# wait(duration:withRange:)

Creates an action that idles for a randomized period of time.

## Declaration

```swift
class func wait(duration sec: TimeInterval, withRange durationRange: TimeInterval) -> SCNAction
```

## Parameters

- `sec`: The average amount of time to wait.
- `durationRange`: The range of possible values for the duration.

## Return Value

Return Value A new action object.

## Discussion

Discussion When the action executes, the action waits for the specified amount of time and then ends. This is typically used as part of a sequence of actions to insert a delay between two other actions. However, you might also use it in conjunction with the runAction(_:completionHandler:) method to trigger code that needs to run at a later time. Each time the action is executed, the action computes a new random value for the duration. The duration may vary in either direction by up to half of the value of the durationRange parameter. This action is not reversible; the reverse of this action is the same action.
