MaterialConditions<T> class

Specifies the minimum sets of pieces required for the game not to be a draw. T should be String for definitions, and is converted to int when the Variant is built.

Properties

combinedPairMaters → List<T>
Pieces that can mate if there are two of them. The pieces can belong to different players. e.g. Bishops in standard chess. Note: this doesn't consider the fact that two bishops of the same colour can't deliver mate.
final
enabled → bool
If material conditions are not enabled, insufficient material draws will not be checked.
final
hashCode → int
The hash code for this object.
no setterinherited
pairMaters → List<T>
Pieces that can mate if there are two of them. The pieces can belong to different players. Note: this doesn't consider the fact that two bishops of the same colour can't deliver mate.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
soloMaters → List<T>
Pieces that can deliver checkmate on their own (or with a king). e.g. Queens and Rooks in standard chess.
final
specialCases → List<List<T>>
Specific sets of pieces that can deliver mate. e.g. a Knight and a Bishop in standard chess.
