Area of Effect Trait 

The 'Area of Effect' trait allows you to graphically highlight an area surrounding a game piece.  The area is shaded with a specified color and transparency.

Transparency Color: The color of the transparency.
Transparency Level: Specifies the opacity of the transparency.  100% is completely opaque.  0% is completely invisible.
Radius: Distance, in local grid units, from the game piece that will be highlighted. If the piece is on a board with a Rectangular Grid or Hex Grid, this distince is in grid units and the shaded area will conform to the grid. Otherwise, it will be a circle with the given radius in pixels.
Always Visible:If selected, the area is always highlighted when the piece is drawn on a Map.
Toggle Visible Command:If not always visible, this is the right-click menu command to show/hide the highlighted area.
Toggle Visible keyboard shortcut:If not always visible, the keyboard shortcut to show/hide the highlighted area..

Note: This trait could be extended in the future to support a light source trait.  For example, the VASL module could support night scenarios where the light source trait could be associated with a flare to illuminate the area surrounding the flare.  Areas outside the light source(s) would be shaded.
