Kennungen, Kachelformen und Platzhalter für die Grafik

Browse Source 
Jede Grafik auf dem Spielfeld bekommt eine Kennung. Art zeichnet sie im
gewählten Stil oder aus einem Bild gleichen Namens unter game/art.
ArtStyle zeichnet vorerst schlichte Platzhalter. TileShape beschreibt
die Nachbarn einer Kachel, damit Felsmassen außen rund und innen
geschlossen gezeichnet werden können. Die drei Stile Warm, Pastell und
Glimmen gibt es schon mit Namen, noch ohne eigene Zeichnungen.
