# dragField()

Creates and returns a field behavior for slowing an object’s velocity.

## Declaration

```swift
class func dragField() -> Self
```

## Return Value

Return Value A field behavior object that applies a drag force to items.

## Discussion

Discussion This field simulates the force of friction on an item. The force is applied in the opposite direction of the affected item’s velocity vector and has a magnitude that is proportional to the field’s strength property and the item’s current velocity.
