Syntax

public interface IReadOnlyLayeredSpatialMap<T> : IReadOnlySpatialMap<T>, IEnumerable<ItemPositionPair<T>>, IEnumerable where T : IHasLayer

Type Parameters

Name	Description
T	Type of element stored in the layered spatial map -- must implement IHasLayer.

Properties

LayerMasker

Object used to get layer masks as they pertain to this spatial map.

Declaration

LayerMasker LayerMasker { get; }

Property Value

Type	Description
LayerMasker

Layers

Gets read-only spatial maps representing each layer. To access a specific layer, instead use GetLayer(Int32).

Declaration

IEnumerable<IReadOnlySpatialMap<T>> Layers { get; }

Property Value

Type	Description
IEnumerable<IReadOnlySpatialMap<T>>

NumberOfLayers

Gets the number of layers contained in the spatial map.

Declaration

int NumberOfLayers { get; }

Property Value

Type	Description
Int32

StartingLayer

Starting index for layers contained in this spatial map.

Declaration

int StartingLayer { get; }

Property Value

Type	Description
Int32

Methods

AsReadOnly()

Returns a read-only reference to the spatial map. Convenient for "safely" exposing the spatial map as a property.

Declaration

IReadOnlyLayeredSpatialMap<T> AsReadOnly()

Returns

Type	Description
IReadOnlyLayeredSpatialMap<T>	The current spatial map, as a "read-only" reference.

CanMoveAll(Point, Point, UInt32)

Returns true if there are items at current on one or more of the layers specified by the layer mask, and all items on those layers at that position can be moved to target; false otherwise.

Declaration

bool CanMoveAll(Point current, Point target, uint layerMask = 4294967295U)

Parameters

Type	Name	Description
Point	current	Location to move items from.
Point	target	Location to move items to.
UInt32	layerMask	Layer mask indicating which layers to check items on.

Returns

Type	Description
Boolean	true if all items at the position current can be moved to the position target; false if one or more items cannot be moved or there are no items to move.

CanMoveAll(Int32, Int32, Int32, Int32, UInt32)

Returns true if there are items at the current position on one or more of the layers specified by the layer mask, and all items on those layers at that position can be moved to the target position; false otherwise.

Declaration

bool CanMoveAll(int currentX, int currentY, int targetX, int targetY, uint layerMask = 4294967295U)

Parameters

Type	Name	Description
Int32	currentX	X-value of the location to move items from.
Int32	currentY	Y-value of the location to move items from.
Int32	targetX	X-value of the location to move items to.
Int32	targetY	Y-value of the location to move items to.
UInt32	layerMask	Layer mask indicating which layers to check items on.

Returns

Type	Description
Boolean	true if all items at the position current can be moved to the position target; false if one or more items cannot be moved or there are no items to move.

Contains(Point, UInt32)

Returns whether or not there is an item in the spatial map at the given position that is on a layer included in the given layer mask. Defaults to searching on all layers.

Declaration

bool Contains(Point position, uint layerMask = 4294967295U)

Parameters

Type	Name	Description
Point	position	The position to check for.
UInt32	layerMask	Layer mask that indicates which layers to check. Defaults to all layers.

Returns

Type	Description
Boolean	True if there is some item at the given position on a layer included in the given layer mask, false if not.

Contains(Int32, Int32, UInt32)

Returns whether or not there is an item in the data structure at the given position, that is on a layer included in the given layer mask.

Declaration

bool Contains(int x, int y, uint layerMask = 4294967295U)

Parameters

Type	Name	Description
Int32	x	X-value of the position to check for.
Int32	y	Y-value of the position to check for.
UInt32	layerMask	Layer mask that indicates which layers to check. Defaults to all layers.

Returns

Type	Description
Boolean	True if there is some item at the given position on a layer included in the given layer mask, false if not.

GetItemsAt(Point, UInt32)

Gets the item(s) associated with the given position that reside on any layer included in the given layer mask. Returns nothing if there is nothing at that position on a layer included in the given layer mask.

Declaration

IEnumerable<T> GetItemsAt(Point position, uint layerMask = 4294967295U)

Parameters

Type	Name	Description
Point	position	The position to return the item(s) for.
UInt32	layerMask	Layer mask that indicates which layers to check. Defaults to all layers.

Returns

Type	Description
IEnumerable<T>	The item(s) at the given position that reside on a layer included in the layer mask if there are any items, or nothing if there is nothing at that position.

GetItemsAt(Int32, Int32, UInt32)

Gets the item(s) associated with the given position that reside on any layer included in the given layer mask. Returns nothing if there is nothing at that position on a layer included in the given layer mask.

Declaration

IEnumerable<T> GetItemsAt(int x, int y, uint layerMask = 4294967295U)

Parameters

Type	Name	Description
Int32	x	X-value of the position to return the item(s) for.
