Methods

boardEquals

boardEquals(other): boolean
Returns true if the .board field from the other board is equal to this one
Parameters
- other: BoardState
Returns boolean
Inherited from BoardState.boardEquals
- Defined in engine/BoardState.ts:405

clearAutoScore

clearAutoScore(): void
Returns void
- Defined in engine/ScoreEstimator.ts:357

clearRemoved

clearRemoved(): void
Clear all stone removals

Returns void
Overrides BoardState.clearRemoved
- Defined in engine/ScoreEstimator.ts:352

cloneBoard

cloneBoard(): JGOFNumericPlayerColor[][]
Returns a clone of .board

Returns JGOFNumericPlayerColor[][]
Inherited from BoardState.cloneBoard
- Defined in engine/BoardState.ts:115

cloneBoardState

cloneBoardState(): BoardState
Clone the entire BoardState

Returns BoardState
Inherited from BoardState.cloneBoardState
- Defined in engine/BoardState.ts:110

computeLibertyMap

computeLibertyMap(): number[][]
Compute the liberty map for the current board. This is used by kidsgo

Returns number[][]
Inherited from BoardState.computeLibertyMap
- Defined in engine/BoardState.ts:328

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
Inherited from BoardState.computeScoringLocations
- Defined in engine/BoardState.ts:414

countLiberties

countLiberties(raw_stone_string): number
Parameters
- raw_stone_string: RawStoneString
Returns number
Inherited from BoardState.countLiberties
- Defined in engine/BoardState.ts:309

estimateScore

estimateScore(trials, tolerance, autoscore): Promise<void>
Parameters
- trials: number
- tolerance: number
- autoscore: boolean
Returns Promise<void>
- Defined in engine/ScoreEstimator.ts:166

`Private` estimateScoreLocal

estimateScoreLocal(trials, tolerance): Promise<void>
Parameters
- trials: number
- tolerance: number
Returns Promise<void>
- Defined in engine/ScoreEstimator.ts:253

`Private` estimateScoreRemote

estimateScoreRemote(autoscore): Promise<void>
Parameters
- autoscore: boolean
Returns Promise<void>
- Defined in engine/ScoreEstimator.ts:178

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
Inherited from BoardState.foreachNeighbor
- Defined in engine/BoardState.ts:351

getGroup

getGroup(x, y): StoneString
Parameters
- x: number
- y: number
Returns StoneString
- Defined in engine/ScoreEstimator.ts:388

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[]
Inherited from BoardState.getNeighboringRawStoneStrings
- Defined in engine/BoardState.ts:249

getProbablyDead

getProbablyDead(): string
Returns string
- Defined in engine/ScoreEstimator.ts:304

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
Inherited from BoardState.getRawStoneString
- Defined in engine/BoardState.ts:272

getStoneRemovalString

getStoneRemovalString(): string
Returns string
- Defined in engine/ScoreEstimator.ts:365

handleClick

handleClick(i, j, mod_key, press_duration_ms): void
Parameters
- i: number
- j: number
- mod_key: boolean
- press_duration_ms: number
Returns void
- Defined in engine/ScoreEstimator.ts:339

score

score(): ScoreEstimator
Computes a rough estimation of ownership and score.

Returns ScoreEstimator
- Defined in engine/ScoreEstimator.ts:395

setRemoved

setRemoved(x, y, removed): 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
Returns void
Overrides BoardState.setRemoved
- Defined in engine/ScoreEstimator.ts:347

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
Inherited from BoardState.toggleSingleGroupRemoval
- Defined in engine/BoardState.ts:126

updateEstimate

updateEstimate(estimated_score, ownership, score?): void
Parameters
- estimated_score: number
- ownership: number[][]
- Optional score: number
Returns void
- Defined in engine/ScoreEstimator.ts:285
