# shadowedBitMask

A mask that defines which lights add shadows to the sprite.

## Declaration

```swift
var shadowedBitMask: UInt32 { get set }
```

## Mentioned in

Lighting a Sprite with Light Nodes

## Discussion

Discussion To determine whether this sprite is affected by being a shadow generated by a light, its shadowCastBitMask property is tested against the light’s categoryBitMask property by performing a logical AND operation. If the comparison results in a nonzero value, the sprite is drawn using a shadowed effect. The default value is 0x00000000 (all bits cleared).
