Game templates
Two tanks on a grassy arena with stone blocks and hedges, a shell bouncing between them

What it solves

The gap

A duel game needs a fair arena, reliable bouncing physics and AI rivals that feel different, not just more accurate.

What it is

This template mirrors every arena, shares one shell simulation between the game and the AI, and describes each rival as one line of numbers that changes how it treats cover.

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

  • Publishing your own local-multiplayer or arena duel game on itch.io, web portals or your site.
  • Learning how a complete real-time duel with AI personalities, local two-player, a daily mode, a menu standard and tests is built in plain JavaScript and Canvas 2D.

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

Arenas

Draw the left half of a map in eleven characters per row ('#' stone, '1' the spawn, 'o' a relic spot); the right half is the same map turned 180 degrees.

Rivals

Each personality is one line in PROFILES: think rate, angles and bounces it tests, aim error, dodging, relic greed, and how often it builds, cages, breaks or holds cover.

No build step

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

Tests included

19 unit tests of the core (settling, firing slits, cracks, the five-cairn limit, armour, relics, sinking, rounds, AI, saves), 69 headless Chrome checks (keyboard for two players, mouse, two gamepads, phones by touch, menus, saves, sound levels) and a smoke test whose bot plays a duel.

Questions

Make and sell any number of your own games from it, and build games for clients. You may not resell or share the source code itself (PN Scripts Template Licence 1.0).

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

No ad or portal SDK, and English only. It is tested in desktop Chrome and phone-sized Chrome viewports with touch (held sideways at 915x412, 844x390 and 750x342; upright shows a turn-sideways hint), not yet on iOS Safari, Firefox or a real phone.

The code was written with AI assistance and checked by PN Scripts with automated tests. All visuals and sounds are generated by code; there are no AI-generated image or audio files.

It is not on sale yet. When it is, this page will link to the store; PN Scripts does not take payment on this site.
