## Place Marker
A Game Piece with this trait will have a menu command that places a different piece (the "marker") on top of this one. You can select any existing piece for the marker or define a new one from scratch. Horizontal offset: The marker will be placed this many pixels to the right of the original piece. Any value other than zero will prevent the marker from stacking with the original piece. Vertical offset: The marker will be placed this many pixels above the original piece. Any value other than zero will prevent the marker from stacking with the original piece. Match Rotation: If selected, and both the original piece and the marker have the Can Rotate trait, then the rotation angle of the marker will be adjusted to match that of the original piece. Place marker: Choose whether the marker should be place on the top of this piece's stack, on the bottom, or directly above/below the triggering piece. Keystroke to apply after placement:Optional keystroke to be applied automatically to the marker immediately after being placed EXAMPLE: If a game uses a fortification counter to indicate fortified status of an army counter, this trait could be given to the army counter to place a fortification marker on the army with a keyboard command, as an alternative to dragging the fortification counter from the Game Piece Palette. |
