FAQ

I want to try this in single player before putting it on my server, is this possible?

You can play against yourself with the command "chess_debug 1". The game will then start with only one player. Turns aren't enforced, and you can move pieces for both sides.

How does the rating system work?

The game boards use an Elo system, meaning the score earned or lost for a game depends on the difference in rating of the two players. Win against someone higher than you to earn more score.

How do I spawn the boards?

There is an admin tool available, "chess_admin_tool". It should be possible to spawn this via your spawn menu or admin mod. Left click will spawn a board, right click will remove the board you're looking at, and reload will bring up a menu. Alternatively, if your gamemode has a spawn menu, you will be able to spawn them through the Entities tab.

How do I save the boards?

You can use the admin tool, as listed above. Alternatively, you can use the console command "chess_save" or the chat commands "!chessave", "!savechess", "/savechess", "/chesssave", or any of the above with the words "draughts" or "checkers" instead of chess. This will save all of your game board's positions to be reloaded when the server restarts or is cleaned up.

What rules are enforced in Chess?

All standard rules should be enforced properly. Notable rules include: Piece move rules; Capture rules; Check and Checkmate rules; Promotion rules; En Passant rule; Castling rules; Stalemate and Draw conditions.

What rules set does Draughts/Checkers use?

The draughts/checkers board uses standard British Draughts/American Checkers rules. The notable features of this rule set are: 8x8 board; If you can capture, you must; No "flying kings".

Is there any way to move the camera while playing?

Holding alt will enable "Free look" mode.
