Pieces
Pieces
Pieces can be added both through text mods and script mods.
See the respective documentation for more information on how to add pieces.
Movement
Pieces are defined by their movement, which is a string in a modified version of Betza's Funny Notation.
Betza's Funny Notation consists of a list of characters that represent the movement of a piece.
There are five types of characters:
Atom: Capital characters that represent a 'leap'. For example, 'N' represents a knight's move, and
BKrepresents a piece that moves like a bishop and a king. Atoms are in all directions unless a direction modifier prefix is used.Repeat: Number characters that represent the number of times an atom is repeated. For example, 'K3' represents a king that moves three squares in any direction. Repeat characters are optional and default to 1. A repeat of 0 means infinite repeats. Alternatively, the atom character can be repeated to also represent infinite repeats (e.g. 'WW' for a wazir that moves any number of squares in any cardinal direction).
Modifier: Lowercase characters that modify the direction or other properties of the atom. For example, 'fB' represents a bishop that moves only forward, and 'cQ' represents a queen that only captures.
Chain: A symbol that chains two atoms together. For example, 'K-N' represents a piece that moves like a king, then like a knight.
Separator: A symbol that separates two groups of atoms. For example, 'K-B|N' represents a piece that moves like a king then bishop, or like a knight.

Chain Characters
Character | Description |
|---|---|
- | Blocking Chain: Moves like the first atom, then like the second atom. Cannot jump the piece the left chain ends on. |
+ | Non-Blocking Chain: Moves like the first atom, then like the second atom. Can jump the piece the left chain ends on. |
-! | Blocking Forced Chain: Moves like the first atom, then like the second atom. Cannot jump the piece the left chain ends on. The move may not end during the left chain. |
+! | Non-Blocking Forced Chain: Moves like the first atom, then like the second atom. Can jump the piece the left chain ends on. The move may not end during the left chain. |
-/ | Blocking Half-Forced Chain: Moves like the first atom, then like the second atom. Cannot jump the piece the left chain ends on. The move may end on the end of the left chain. |
+/ | Non-Blocking Half-Forced Chain: Moves like the first atom, then like the second atom. Can jump the piece the left chain ends on. The move may end on the end of the left chain. |
Separator Characters
Character | Description |
|---|---|
| | Separator: Moves like the first atom, or like the second atom. |
Examples
mBcK: A piece that moves like a bishop and captures like a king.W-B|F-R: A piece that moves like a wazir, then like a bishop, or like a ferz, then like a rook (Andromeda).WB: A piece that moves like a wazir or a bishop.fW3: A piece that moves forward up to 3 squares.brB: A piece that moves diagonally backward-right like a bishop.
Old notation
The old notation is still supported for compatibility reasons. It is a string in the format of (a,r,f,b),(a,r,f,b),...;(a,r,f,b),(a,r,f,b),..., a = ahead, r = right, f = forward, b = backward. The first group is the non-capturing movement, and the second group is the capturing movement. For example, (1,0,1,1):(0,1,1,1):(1,1,1,1):(1,-1,1,1);(1,0,1,1):(0,1,1,1):(1,1,1,1):(1,-1,1,1) represents a piece that moves like a king.
