# Risk Dice Modifier

An implementation of risk rolls as found for example in the Splittermond game
system.

This module provides a new dice modifier `ri` for regular Dice. This modifier
causes the dice roller to keep / drop dice according to the following rules:
- If there are either two `1`s or a `1` and a `2` in the results, keep only
  these dice.
- Otherwise, keep the two dice with the highest results.

```
/roll 4d10ri # Roll 4d10 in risk die mode
```

## Development

### Prerequisites

In order to build this module, recent versions of `node` and `yarn` are required.
We recommend using the latest lts version of `node`, which is `v14.15.4` at the
time of writing. 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 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 build:watch
```

to watch for changes and automatically build as necessary.

### Linking the built module 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/Data"
}
```

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

Then run

```
yarn link-project
```
