Wolf_und_Schaf (Wolf and Sheep)

Die soll den letzten Wurf anzeigen, allerdings scheint es nicht der letzte eigene zu sein, sondern der des Gegners. Hab den Fehler bisher nicht finden können - eigentlich hat jeder Spieler sein eigenes Visier-Objekt...

also Herr Lehrer: das Problem ist, dass nicht zwischen dem Wurf vom Linken und Rechten unterschieden wird, sondern einfach nur der letzte Wurf, eben der vom Gegner, angezeigt wird.
