What it solves

The gap

Duel games need a rule that is easy to read yet deep, an AI that can be tuned from easy to hard, and fair controls for two people on one keyboard.

What it is

This template has one three-line rule, an AI built on the same commands as the players, and an input map for two keyboards and touch.

How you use it

Unzip, serve the folder and open index.html, then edit game.js; npm test plays it again in headless Chrome.

Source code of a real, playable game to reskin and learn from, with a smoke test whose bot plays it.

Who it is for

Use it when

  • Making your own one-on-one fighting or duel game with local multiplayer and a tunable AI.
  • Learning how a complete fencing duel game is built in plain JavaScript and Canvas 2D.
  • Building a branded mini-game for a client.

Built for

  • Web and indie game developers who know some JavaScript.
  • Developers who want a finished, tested game to build on instead of a blank canvas.

What you get

One skill value per rival

Reaction delay, parry chance and aggression are all derived from a single number, so a new rival is one line in a table.

Same commands for everyone

Keys, touch buttons, the computer fencers and the test bot all call the same step, line and lunge functions.

No build step

Plain JavaScript and Canvas 2D; open index.html through any static server and edit game.js.

A smoke test

A headless Chrome test loads the game, checks the console, presses keys and taps, and lets the built-in bot play a run to its result screen.

Any static web server to run the game, and some JavaScript. Node.js 22.12 or newer and Google Chrome run the smoke test.

No ad or portal SDK, and English only. It is tested in desktop Chrome and a phone-sized Chrome viewport with touch, not yet on iOS Safari, Firefox or a real phone.
