Pertama Mencapai Lima

Termasuk bagian Proyek dalam perjalanan Pygame di Coddy. Pelajaran 19 dari 31.

Pemain pertama yang mencapai 5 poin menang. Simpan nama pemenang dalam variabel yang dimulai dengan None, nilai Python untuk "belum ada":

winner = None

if left_score == 5:
    winner = "Left player wins!"
elif right_score == 5:
    winner = "Right player wins!"

Uji dengan winner is None atau winner is not None. Setelah seseorang menang, bola akan terus menunggu: tombol Space hanya melakukan servis saat winner is None.

Tampilkan pemenang di tengah pada (300, 120), menggantikan pesan servis.

Tantangan

Sedang

Sebelum perulangan, tetapkan winner = None.
Setelah pemberian skor, tetapkan winner menjadi "Left player wins!" saat left_score == 5, atau "Right player wins!" saat right_score == 5.
Tombol Space hanya melakukan servis saat winner is None.
Saat ada pemenang, tampilkan pemenang di tengah pada (300, 120), bukan Press Space to serve.
