# addByCameraDistance(to:levels:)

Adds Level of Detail configuration using distance-based switching to an entity .

```
static func addByCameraDistance(to entity: Entity, levels: [(entities: LevelOfDetailComponent.DetailLevel, maxDistance: Float)])
```

## Parameters

`levels`

An array of levels, where each level specifies the entities
to display and the maximum camera distance at which they are visible.

## Discussion

Each level pairs a set of entities with a maximum camera distance threshold.
Entities within a level are shown or hidden together. Thresholds must be
in ascending order; the last threshold is typically `.infinity`.

Each entity in the provided levels is added as a child of the entity the component will be added to.
Children not included in any level are unaffected by LOD switching.
