السلام عليكم ورحمة الله وبركاته، اخوتي الكرام احتاج لمساعدتكم في اتمام اللعبة، لم اعتد بعد على البرمجة بجافا، ومطلوب مني إضافة توقيت(Timer) وكذلك امكانية حفظ (Save) للعبة مع العلم انه عندما يتم حفظها يمكن إتمامها في وقت لاحق.
وجزاكم الله عني خيرا.
مساعدة في اضافة timer و Save للعبة

السلام عليكم ورحمة الله وبركاته.
اريد من فضلكم حفظ قطع اللعبة وكذلك اماكنها على الشاشة حتى يتسنى فتحها تانية وفي نفس المواقع التي كانت تتواجد بها.
شكرا لكم.
// ### Should Pieces be implemented as BufferedImages backed by Rasters,

// ### Classic piece edges are problematic. First of all, the corners are
// weird. Secondly, the edges are probably too close together. This is
// causing the bevels to overlap very slightly, so they don't look quite
