Readonly height

removal

white_prisoners

Readonly width

boardEquals

• boardEquals(other): boolean

• Returns true if the .board field from the other board is equal to this one

  Parameters

  • other: BoardState

  Returns boolean

clearRemoved

• clearRemoved(): void

• Clear all stone removals

  Returns void

cloneBoard

• cloneBoard(): JGOFNumericPlayerColor[][]

• Returns a clone of .board

  Returns JGOFNumericPlayerColor[][]

cloneBoardState

• cloneBoardState(): BoardState

• Clone the entire BoardState

  Returns BoardState

computeScoringLocations

• computeScoringLocations(area_scoring): ScoringLocations

• Computes scoring locations for the board. If area_scoring is true, we will use area scoring rules, otherwise we will use territory scoring rules (which implies omitting territory in seki).

  Parameters

  • area_scoring: boolean

  Returns ScoringLocations

countLiberties

• countLiberties(raw_stone_string): number

• Parameters

  • raw_stone_string: RawStoneString

  Returns number

foreachNeighbor

• foreachNeighbor(pt_or_raw_stone_string, callback): void

• Parameters

  • pt_or_raw_stone_string: JGOFIntersection | RawStoneString
  • callback: ((x, y) => void)
    • • (x, y): void

      • Parameters

        • x: number
        • y: number

        Returns void

  Returns void

getNeighboringRawStoneStrings

• getNeighboringRawStoneStrings(raw_stone_string): RawStoneString[]

• Returns an array of groups connected to the given group. This is a bit faster than using StoneGroupBuilder because we only compute the values we need.

  Parameters

  • raw_stone_string: RawStoneString

  Returns RawStoneString[]

getRawStoneString

• getRawStoneString(x, y, clearMarks): RawStoneString

• Returns an array of x/y pairs of all the same color

  Parameters

  • x: number
  • y: number
  • clearMarks: boolean

  Returns RawStoneString

setRemoved

• setRemoved(x, y, removed, emit_stone_removal_updated?): void

• Sets a position as being removed or not removed. If emit_stone_removal_updated is set to false, the "stone-removal.updated" event will not be emitted, and it is up to the caller to emit this event appropriately.

  Parameters

  • x: number
  • y: number
  • removed: boolean
  • emit_stone_removal_updated: boolean = true

  Returns void

toggleSingleGroupRemoval

• toggleSingleGroupRemoval(x, y, force_removal?): {
      group: RawStoneString;
      removed: boolean;
  }

• Toggles a group of stones for removal or restoration.

  By default, if we are marking a group for removal but the group is almost certainly alive (two eyes, etc), this will result in a no-op, unless force_removal is set to true.

  Parameters

  • x: number
  • y: number
  • force_removal: boolean = false

  Returns {
      group: RawStoneString;
      removed: boolean;
  }

  • group: RawStoneString

  • removed: boolean
