Python platformer لعبة مشكلة في الانتقال إلى المستوى التالي

حسنًا ، لقد نجحت. فيما يلي الرمز ، فهو يعمل عن طريق إعادة تهيئة الأنظمة الأساسية والكيانات إلى القيمة المطلوبة (المطابق مع المستوى ، وإضافة المزيد من المستويات أيضًا ، وتغيير المستوى ، وقول فقط إذا

levelNum == 3:
     buildLevel(level3)

وإلا فإن الطريقة الأكثر فعالية ستضع القائمة في القائمة ، وتضبط المستوى رقمًا أيضًا 0 هيريس الشفرة الكاملة ، أيضًا ، قد لا تعمل إذا حصلت على "اجتياز" المستوى الثاني لأنه لا يوجد المستوى الثالث ، لذلك قد ترغب في اجعله يقول التهاني أو شيء من هذا.
