constructor

• HashGridProxy<T>(object: T, gridSize: number): HashGridProxy<T>

• Type parameters

  • T: { bounds: BoundingBox }

  Parameters

  • object: T

  • gridSize: number

  Returns HashGridProxy<T>

Properties

bottomY

bottomY: number

bottom bounds y hash coordinate

bounds

bounds: BoundingBox

cells

cells: HashGridCell<T, HashGridProxy<T>>[] = []

readonlygridSize

gridSize: number

Grid size in pixels

hasZeroBounds

hasZeroBounds: boolean = false

id

id: number = -1

leftX

leftX: number

left bounds x hash coordinate

publicobject

object: T

rightX

rightX: number

right bounds x hash coordinate

topY

topY: number

top bounds y hash coordinate

Methods

clear

• clear(): void

• Clears all collider references

  ---

  Returns void

hasChanged

• hasChanged(): boolean

• Has the hashed bounds changed

  Refreshes bounds as a side effect (via updateBounds) so callers that need the current bounds regardless of the result (see SparseHashGrid.update) don't have to recompute them

  ---

  Returns boolean

update

• update(): void

• Updates the hashed bounds coordinates

  Only called after hasChanged returns true, which has already refreshed bounds

  ---

  Returns void

updateBounds

• updateBounds(): void

• Update bounds of the proxy

  ---

  Returns void
