Methods

addArrow(type, from, to)

removeArrows(type, from, to)

To remove all arrows, call chessboard.removeArrows() without parameters. To remove all arrows of a specific type (type "danger"), call chessboard.removeArrows(ARROW_TYPE.danger). To remove all arrows starting at "e2" you can call chessboard.removeArrows(undefined, "e2") and so on...

getArrows(type, from, to)

To get all arrows, call chessboard.getArrows() without parameters, as with removeArrows(type, from, to).
