addByCameraDistance(to:levels:)
Adds Level of Detail configuration using distance-based switching to an entity .
Declaration
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.
