Darkness Dependent Vision

A module for Foundry Virtual Tabletop that provides functionality to make the dim and bright vision of tokens depend on the scene's darkness level.

Installation

To install and use the Darkness Dependent Vision module for Foundry Virtual Tabletop, simply paste the following URL into the Install Module dialog on the Setup menu of the application.

https://git.f3l.de/ghost/darkness-dependent-vision/-/raw/latest/src/module.json?inline=false

Usage

In order to configure the darkness range in which a token has dim and bright vision, a dialog is provided that can be accessed from a header button in the Token Configuration:

In the next image, you can see an example of the module in action: The token is configured to only have bright vision at a darkness level between 0 and 0.5, but the scene's darkness level is set to 0.6, so the token has no bright vision. On the other hand, the token is also configured to have dim vision at a darkness level between 0 and 0.7, so it does have dim vision.

Development

Prerequisites

In order to build this module, 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 build:watch

to watch for changes and automatically build as necessary.

Linking the built project to Foundry VTT

In order to provide a fluent development experience, it is recommended to link the built module 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": "/absolute/path/to/your/FoundryVTT/Data"
}

(if you are using Windows, make sure to use \ as a path separator instead of /)

Then run

yarn link-project

On Windows, creating symlinks requires administrator privileges, so unfortunately you need to run the above command in an administrator terminal for it to work.
