Arcade: three games in the conversation - Snake, Breakout and Pong - with persistent top-ten leaderboards the model can read. A Nodecode rewrite of leoresendedop-sys/hermes-arcade by leoresendedop-sys.

Get it

Tell the agent "add the arcade cell", or run nodecode add nc://arcade.

Set it up

Nothing is required. The arcade section of the config refines the cabinet: initials (the 1-3 letters your scores are filed under, YOU by default), keep_scores (ten), snake_width and snake_height (16 by 10; Neon Snake's grid), and answer_chars (1,200; how much of one frame an answer carries). config.example.jsonc is the section written out. The board is written under the Nodecode home, in arcade/scores.txt, and nothing is uploaded.

Use it

The cabinet is one machine, one game at a time, the way it stands in a room: a run starts, you call the next move, and the answer is the whole frame, the score, and - when the run ends - the rank the score reached.

/arcade                          the boards of all three games
/arcade snake nneee              three steps up, three right
/arcade breakout 5               put the paddle on column 5
/arcade pong 4                   cover zones 3-5 against the serve

• The tool arcade_play takes game, moves (one character a turn) and, if you want to file the score under someone else, initials. A move is a letter in Snake (n, s, e, w) and a column or zone in Breakout and Pong (1-9).
• arcade_games lists the cabinet, what each game pays and how a move is written.
• arcade_top_scores reads the top ten a game with their initials and points, and how many times each has been played - the answer the original's tool of the same name gave.
• arcade_player_stats answers total plays, plays a game, each game's champion, and with initials every board entry filed under them.
• (help :arcade) is the manual the model reads when it wants the full rules.

What comes back from a move:

Neon Snake  score 20

Snake pays 10 points a pellet and ends on a wall or its own body; Breakout pays 20 a brick and 250 a level, with three lives, and ends at the third miss; Pong is first to seven, 100 a point and 500 for the win. Scores are filed under your initials when a run ends, and the board keeps the ten best a game.

What it does not do: it runs no server and has no tab of its own, so there is no canvas, no glow, no particles and no sound; a run is a frame of text per move, not sixty frames a second. It reads and writes one file, the board, and never a credential, a network or a clock-dependent random.
