SymmetricPreComputedVisionTries

class SymmetricPreComputedVisionTries(radius: Int)(source)

A provider for pre-computed tries for the line of sight (LoS) on a symmetric grid.

This class provides you with the ability to pre-compute the tries in order to enhance the speed of common operations e.g., line-of-sight (LoS), field-of-view (FoV), etc.

Parameters

radius

the vision radius for the tries.

Constructors

SymmetricPreComputedVisionTries

constructor(radius: Int)

Properties

fastLoSMap

val fastLoSMap: MutableMap<Int, MutableList<TrieNode>>

root

val root: TrieNode

Functions

fieldOfView

fun fieldOfView(from: AxisPoint, doesBlockVision: (Int, Int) -> Boolean): Set<HexCoordinates>

fun fieldOfView(from: AxisPoint, doesBlockVision: (Int, Int) -> Boolean, callback: (Int, Int) -> Unit)

fun fieldOfView(fromQ: Int, fromR: Int, doesBlockVision: (Int, Int) -> Boolean, callback: (Int, Int) -> Unit = { _, _ -> })

Generates a field of view from a specified point.

lineOfSight

fun lineOfSight(from: AxisPoint, to: AxisPoint, radius: Int = this.radius, doesBlockVision: (Int, Int) -> Boolean): Set<HexCoordinates>

fun lineOfSight(from: AxisPoint, to: AxisPoint, radius: Int = this.radius, doesBlockVision: (Int, Int) -> Boolean, callback: (Int, Int) -> Unit): Boolean

fun lineOfSight(fromQ: Int, fromR: Int, toQ: Int, toR: Int, radius: Int = this.radius, doesBlockVision: (Int, Int) -> Boolean, callback: (Int, Int) -> Unit): Boolean

Converts provided coordinates into line-of-sight data.
