# start(atTime:)

Starts playing the pattern at the specified time.

## Declaration

```swift
func start(atTime time: TimeInterval) throws
```

## Parameters

- `time`: The time from which to start playing the pattern.

## Mentioned in

Playing a single-tap haptic pattern

## Discussion

Discussion If time is 0 or any value less than the haptic engine’s currentTime, the pattern starts playing immediately. If you call this method on a player that’s already playing, it restarts itself at the beginning of the pattern.
