C# Class Nez.Spatial.SpatialHash

Public Properties

Property	Type	Description
gridBounds	Microsoft.Xna.Framework.Rectangle

Method	Description
SpatialHash ( int cellSize = 100 ) : System
aabbBroadphase ( RectangleF &bounds, Collider excludeCollider, int layerMask ) : HashSet	returns all objects in cells that the bounding box intersects
clear ( ) : void
debugDraw ( float secondsToDisplay, float textScale = 1f ) : void	debug draws the contents of the spatial hash. Note that Core.debugRenderEnabled must be true or nothing will be displayed.
debugDrawCellDetails ( int x, int y, int cellCount, float secondsToDisplay = 0.5f, float textScale = 1f ) : void
getAllObjects ( ) : HashSet	returns all the Colliders in the SpatialHash
linecast ( Vector2 start, Vector2 end, RaycastHit hits, int layerMask ) : int	casts a line through the spatial hash and fills the hits array up with any colliders that the line hits
overlapCircle ( Vector2 circleCenter, float radius, Collider results, int layerMask ) : int	gets all the colliders that fall within the specified circle
overlapRectangle ( RectangleF &rect, Collider results, int layerMask ) : int	gets all the colliders that fall within the specified rect
register ( Collider collider ) : void	adds the object to the SpatialHash
remove ( Collider collider ) : void	removes the object from the SpatialHash
removeWithBruteForce ( Collider obj ) : void	removes the object from the SpatialHash using a brute force approach

Method	Description
cellAtPosition ( int x, int y, bool createCellIfEmpty = false ) : List
cellCoords ( float x, float y ) : Point
cellCoords ( int x, int y ) : Point
