# DS4

An implementation of the Dungeonslayers 4 game system for [Foundry Virtual
Tabletop].

This system provides sheet support for Actors and Items and mechanical support
for dice and rules necessary to play games of Dungeonslayers 4.

## Installation

To install and use the Dungeonslayers 4 system for Foundry Virtual Tabletop,
simply paste the following URL into the **Install System** dialog on the Setup
menu of the application.

https://git.f3l.de/api/v4/projects/dungeonslayers%2Fds4/packages/generic/ds4/latest/system.json

## Development

### Prerequisites

In order to build this system, recent versions of `node` and `yarn` are
required. Most likely using `npm` also works but only `yarn` is officially
supported. We recommend using the latest lts version of `node`. If you use `nvm` to manage your `node` versions, you can simply run

```
nvm install
```

in the project's root directory.

You also need to install the project's dependencies. To do so, run

```
yarn install
```

### Building

You can build the project by running

```
yarn build
```

Alternatively, you can run

```
yarn watch
```

to watch for changes and automatically build as necessary.

### Linking the built system to Foundry VTT

In order to provide a fluent development experience, it is recommended to link
the built system to your local Foundry VTT installation's data folder. In order
to do so, first add a file called `foundryconfig.json` to the project root with
the following content:

```
{
    "dataPath": "<path to your home directory>/.local/share/FoundryVTT"
}
```

On platforms other than Linux you need to adjust the path accordingly.

Then run

```
yarn link-package
```

### Running the tests

You can run the tests with the following command:

```
yarn test
```
