Property Value Types

Composition Type

This type will be extended to contain an unlimited number of "simple" values. For examples, OT uses three values.

FF4 definition Compose = ValueType ":" ValueType
FF5 definition Compose = ValueType ":" ValueType { ":" ValueType }

Color Type

The color type for property values is made ignorant of games. For Go (and other two player games) everything remains as it was. One player is named B, the other W. For multi-player games the color is stored as numerical value (1,2,3,...).

FF4 definition Color = ("B" | "W")
FF5 definition Color = ("B" | "W") for two player games and Color = Digit {Digit} for multi-player games

New: Extended Color Type

The new type extended color consists of all entities the color type has, plus "A" for all players.

FF4 definition -
FF5 definition ExtColor = ("B" | "W" | "A") for two player games and Color = ("A" | Digit {Digit}) for multi-player games

FF4 definition	`Compose = ValueType ":" ValueType`
FF5 definition	`Compose = ValueType ":" ValueType { ":" ValueType }`

FF4 definition	`Color = ("B" \| "W")`
FF5 definition	`Color = ("B" \| "W") for two player games and Color = Digit {Digit} for multi-player games`

FF4 definition	-
FF5 definition	`ExtColor = ("B" \| "W" \| "A") for two player games and Color = ("A" \| Digit {Digit}) for multi-player games`
