Simple Fog

A module for FoundryVTT that lets you draw fog of war manually.

Feature Overview Video

Encounter Library did a review of Simple Fog which explains how it works much better than I can, please check it out if you would like an idea how this module works.

Features

• Simple Fog implements a manual fog of war layer above the core vision layer
  • Enable and disable the Simple Fog layer at any time, per scene
  • This allows you to use both Simple Fog AND the core vision for line of sight, or alternatively use only one or the other, on a scene by scene basis
• Tokens can be automatically hidden and revealed when underneath Simple Fog with a configurable opacity threshold
• Implements a history system so you can easily undo your actions
• Various drawing tools for drawing and erasing fog of war manually
  • Brush tool
  • Hotkeys for quickly changing brush size [ ]
  • Rectangle & Ellipse tool
  • Hold shift to force equal width & height while drawing
  • Polygon Shape tool
  • Click the orange handle to finish your drawing, or right click to cancel
  • Grid tool
  • Reveals any grid square you drag across, works for both Hex and Square grids
  • Room tool
  • Reveals walled rooms. Hold the SHIFT key to take doors into account.
  • This feature doesn't detect an actual "room", it is limited by sight, so it won't reveal fog over corners.
• Add an image to the Simple Fog layer which overlays the selected tint for both GMs and Players.

Scene Configuration

Allows you to set various options which affect the entire layer for the current scene

• Set an image overlay for the fog on both player and GM screens.
• Set the opacity of the entire fog layer for both players and GMs
• Animate transitions in opacity, allowing for effects such as "Fade to Black"
• Change tint of the fog for both player and GM, for example to indicate a green poison cloud
• Apply a blur filter for soft edges to fog
• Enable or disable the automatic vision feature
• Save your settings as the new default when creating a scene

Planned Future Features

• More AutoVisibility options:
  • Reveal based on center of token
  • Reveal only if entire token visible
  • Reveal if any part of token is visible
• Brush Smoothing / Interpolation
• Sepia / monochrome filters
• Add indicator icon of player controlled icons hidden under fog
• Currently incompatible with the module "GM Scene Background" when a GM layer is active

Build

Install all packages

npm install

npm build scripts

build

will build the code and copy all necessary assets into the dist folder and make a symlink to install the result into your foundry data; create a foundryconfig.json file with your Foundry Data path.

{
  "dataPath": "~/.local/share/FoundryVTT/"
}

build will build and set up a symlink between dist and your dataPath.

npm run-script build

NOTE:

You don't need to build the foundryconfig.json file you can just copy the content of the dist folder on the module folder under modules of Foundry

build:watch

build:watch will build and watch for changes, rebuilding automatically.

npm run-script build:watch

clean

clean will remove all contents in the dist folder (but keeps the link from build:install).

npm run-script clean

prettier-format

prettier-format launch the prettier plugin based on the configuration here

npm run-script prettier-format

package

package generates a zip file containing the contents of the dist folder generated previously with the build command. Useful for those who want to manually load the module or want to create their own release

npm run-script package
