```

## Mentioned in

Lighting a Sprite with Light Nodes

## Discussion

Discussion To determine whether this sprite is lit by a light node, the sprite’s lightingBitMask 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 lit by this light. The default value is 0x00000000 (all bits cleared).
