Memory

Die Karten können mit einem Mausklick aufgedeckt werden. Falls Sie eigene Bilder verwenden möchten, speichern Sie Ihre neue Bilder lokal im userhome/gamegrid/sprites. Die Bilder werden beim Erstellen des Jars automatisch mitverpackt.

Unsere Bilder sind 113 x 113 Pixel gross. Falls Sie eine andere Grössen verwenden möchten, müssen Sie die Zeile
super(4, 4, 115, null, null, false)
entsprechend anpassen.
