Kingdom architects is intended to be a combined simulation and city building game around building your own kingdom and protecting it from hordes of evil monsters. It is intended to be single-player and playable both on mobile screens and desktop size clients. Your kingdom might last for decades or only seconds, who knows what the legends of your reign will be.

• Play both using the keyboard and mouse/touch.
• Only depend on browser-apis, no extra libraries.
• Kingdoms are ephemeral, they only exists within the memory of the browser. Once its closed only bards will sing the tales of your kingdom. Something rewarding should happen from the start.
• Progress in some way should be able to be carried over into future kingdoms, rogue-lite style.

Great, if you feel like it aligns with the goal for the project open a thread under discussion with some details on your idea

Fantastic, getting bug reports is important. File an issue with steps to reproduce 🙏.

Wow, thanks! First see if there are any open issues or open a thread under discussion on the improvement or contribution you would like to make.

• Node v20 or higher
• An editor to edit typescript with

Install the required development packages (typescript and rollup) with npm i. Build and bundle the typescript source with npm run build. npm run start will start a development server and give you a link to test out the game locally. Use your favourite IDE to edit any typescript game code. If you want to contribute on the development on the game, here follows some notes on the architecture for the game/application and some tools used during development.

The architecture of the game is loosely based around three concepts:

• A timer ticking each second
• An entity tree and component system
• A state system for the HUD/GUI

Ever second a timer invokes two code paths for most of the game components. An update function and a draw function. The update function should only be invoked once per timer tick, but the draw method can be called multiple. Be wary of putting logic depending on a timed update as it will be invoked potentially more than one time per tick when input events happen or other actions are perfomed. Panning the gameworld is a good example of when the draw method of the different classes are invoked, this method is executed on each drag event from the browser.

A entity component system is in the works where all items in the world are tied to an entity with some amount of componets on it handle updates and draw actions. Some exceptions exists like tiles where all tiles belong to the same entity with a component that is responsible for drawing and handling all the tiles. All new game world items and data will be stored in components on entities. If you create new components or jobs, remember to run the Typelistgen tooling

Items that are not directly connected to the game world, like menus and screens are considered InteractionStates these are screens that can be navigated to and from in a stack. States can draw custom actions and handle events as well as setting up complex views using the custom UI system

Typescript and rollup is used for transpiling, typechecking and bundling the code. This is performed with the build npm task.

Note: The test suite uses the node test runner and requires node >=20.

Some tests already exists for the game, these are made with the built in node test runner. Note that files are not automatically built when tests are run. These needs to be built independently (however the npm test script includes the tsc step before the tests are run). Some files are currently just scaffold and some contain actuall test code. Tests can be run with npm test.

• Task: spritepack
• Note: typescript sources needs to be built before the task can run

To optimize, remove unused parts of images and bundling them together into a spritebin the spritepack npm task can be used. If you update any of the images in asset you need to run this task to get the updated version to show up in game. The source for this can be found in ts/tool/spritepack.

• Task: generate-loaders
• Note: typescript sources needs to be built before the task can run

To support persisting and loading the state of components and jobs, we need a list of the constructors for all components and jobs. To update the generated list of these, or the path for their imports run the generate-loaders npm task.
