Beaver's System Interface

This module is for developers only. It helps to write system agnostic foundry vtt modules.

Beaver's System Interface is an interface for often used system dependent functionalities. When you write your module you just call the methods of this interface instead of writing system dependend code. It should speed up your development as well as gives your module the ability to work instantly for multiple Systems.

Beavers System Interface: Is an interface with some default implementations for common system dependent functionalities.

BSA-X: Beavers System Adapter for System x is an implementation of Beavers System Interface for System X.

The intention is that BSA-X implementations are kept small and simple, while complex algorithm are implemented within BSI.

Supported systems

Main Functionality v1

• configurations e.g. list of skills,abilities,currencies
• adjust Currencies
• manipulate Items
• roll on skill,abilities
• UI Dialog Selectbox
• TokenMovement

How to work with this

Setup

• register your module to BSI

Hooks.on("beavers-system-interface.init", async function () {
    beaversSystemInterface.addModule("beavers-crafting");
});

• enable your module only when a BSA implementation for the current system is found

Hooks.once("beavers-system-interface.ready", async function () {

}

Use BeaversSystemInterface

your module can access all "System" interface methods and properties:

functions

types.ts

e.g.

const selection = await beaversSystemInterface.uiDialogSelect({
    choices:[
    {text:"Carpenter's Tools:8",img:".."},
    {text:"Cartographer's Tools:8",img:".."},
    {text:"Weaver's Tools:8",img:".."},
    {text:"Alchemist's Supplies:8",img:".."}
  ]
});

TypeScript Support

When you use typescript for your module development, you can attach the types for beaversSystemInterface so your IDE can help you with spellings and autocompletion. There should be a npm package in the same version as the module.

package.json

{
  ...
  "devDependencies": {
    "beavers-system-interface": "^1.0.6"
  }
}

tsconfig.json

{
  "compilerOptions": {
    ...
    "types": [ "beavers-system-interface/src"]
  }
}

How to write BSA-X implementations

Setup

• register your BSA-X to BSI

Hooks.on("beavers-system-interface.init", async function(){
  beaversSystemInterface.register(new Dnd5e());
});

Implement the SystemApi

create A class that implements the SystemApi

export class Dnd5e implements SystemApi {
  
}

and then implement it SystemApi

some methods have a default implementation see functions

Set your version to the major version of the SystemApi you implement.

Why this module

• Request for another system

  I got requested to make my module available for another system. I did not know this system, so I searched for a way to allow others to write the system dependent parts for their system they know without breaking my module.

• Discussion about "open gaming Licence"

  With the discussion of wizards of the coast "open gaming licence", I do no longer want to write a module explicitly for dnd especially if I can get sued for any or no reasons. So I decided to rewrite my module system agnostic. Then I only need to write an implementation of BSI for dnd5e, this implementation does not enable anyone todo anything it just connects an interface to its implementation this can not be sued.

• Multiple modules use the same code
