# affectedByGravity

A Boolean value that indicates whether this physics body is affected by the physics world’s gravity.

## Declaration

```swift
var affectedByGravity: Bool { get set }
```

## Discussion

Discussion The physics world’s gravity property defines the gravitational forces applied to volume-based bodies in the scene. The default value is true. This property is ignored on edge-based bodies, which are always unaffected by gravity. Physics bodies with affectedByGravity set to false are still affected by the gravity fields created by linearGravityField(withVector:) and radialGravityField().
