SokobanSnapshot¶

class SokobanSnapshot(moves_data: str = '')¶

Bases: Snapshot

Snapshot implementation for Tessellation.SOKOBAN and SokobanTessellation.

__init__(moves_data: str = '')¶

HexobanSnapshot¶

class HexobanSnapshot(moves_data: str = '')¶

Bases: Snapshot

Snapshot implementation for Tessellation.HEXOBAN and HexobanTessellation.

__init__(moves_data: str = '')¶

TriobanSnapshot¶

class TriobanSnapshot(moves_data: str = '')¶

Bases: Snapshot

Snapshot implementation for Tessellation.TRIOBAN and TriobanTessellation.

__init__(moves_data: str = '')¶

OctobanSnapshot¶

class OctobanSnapshot(moves_data: str = '')¶

__init__(moves_data: str = '')¶

Snapshot¶

class Snapshot(tessellation: Tessellation, moves_data: str = '')¶

Base class for game snapshots and accompanying metadata.

Game snapshot is a sequence of pusher steps representing actual steps, jumps (in reverse solving mode) and pusher selections (in Multiban variant).

classmethod is_move_step(character: str) → bool¶

classmethod is_push_step(character: str) → bool¶

classmethod is_pusher_step(character: str) → bool¶

classmethod is_marker(character: str) → bool¶

classmethod is_snapshot(line: str) → bool¶

True if line contains only:

movement characters
other snapshot characters (ie. jump markers)
Rle characters
spaces and newlines

to_str(rle_encode=False) → str¶: Formatted output of parsed and validated moves data.

property tessellation: Tessellation¶

property moves_data: str¶

property pusher_steps: List[PusherStep]¶: Game engine representation of pusher steps.

Warning

Setting this property will also replace moves_data.

property pushes_count: int¶: Count of box pushing steps.

property moves_count: int¶: Count of steps that are not pushing a box and are not selecting pusher.

property jumps_count: int¶: Count of groups of steps that are jumps. Jumps are possible when board is being solved in reverse mode.

property is_reverse: bool¶: True if snapshot contains any jumps.
