# dragField()

Creates a field node that applies a force that resists the motion of physics bodies.

## Declaration

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

## Return Value

Return Value A new drag field node.

## Discussion

Discussion The force is applied in the opposite direction of the physics body’s velocity property and has a magnitude proportional to the field’s strength property and the physics body’s speed.  This field models Stoke’s Law.
