Level Format

A Windstille level or sector needs to hold multiple tilemaps, some meta information, object placments and information on the background and the triggers/scripts. S-Expressions will be used as textbased-format, if necessary there might also be a compiled binary format, but textbased formats have shown to be very flexlible in the develompent procress, so we start with them first.

There are three default tilemaps, 'foreground', 'background' and 'interactive'. 'interactive' is the one on which the player walks normally, 'foreground' is for stuff infront of the player, 'background' for tiles behind the player, both don't have any impact on collision detection.

(windstille-sector (name "City") (music "foo.ogg")

(objects (tilemap (name "forground") (x-offset 50) (y-offset 50) (width 100) (height 500) (paralax-x 0.5) (paralax-y 0.5) (data 1 0 12 0 0 0 0 0 ....) )

 (box (pos 10 20))
 (enemy (pos 10 20)
        (energy 50)))
