Black Knight
Chess Mod is a mod developed by Yarmiplay and released on 31.12.2023 for the New year.
The mod adds "Chess Mode" and makes it the only mode available to play.
The rules for chess mode are as follows: For each apple in the count setting, there will exist 2 chess pieces on the board of opposite colors.
When the snake eats a chess piece of any color, the "head state" will become that chess piece and color - "pickup" mode. When the head moves in range for that chess piece to capture a piece of the opposite color, it will immediately do so to the closest piece available, opening a maximum of one apple in it's place, functionally similar to key mode or sokoban mode.
If the snake head moves into any chess piece of any color, or any open apple, while in the state that it picked up a piece from the board before capturing, it will die and the game will end. The snake can only be cleared of "pickup" mode once it captures a piece of opposite color which will always be available. The snake can capture any piece of the opposite color without restrictions, as long as it's done according to how that piece moves in chess.
Example: if the snake captured a Black Knight, it can "capture" any White piece by being a Knight move away from it, clearing the head status, allowing the snake to eat a new chess piece (of any color) or an apple.
Eating an apple will spawn 2 new chess pieces of opposite color, with spawn radius away from the snake's head.
The chances of each piece spawning:
- Pawn - 50%
- Knight - 12.5%
- Bishop - 12.5%
- Rook - 12.5%
- Queen - 6.25%
- King - 6.25%
There is no meaning to capturing kings or picking them up, they are treated like any other piece.
Pawns stay pawns even at the border.
