Melarikan Diri dari Menara

Termasuk bagian Proyek dalam perjalanan Pygame di Coddy. Pelajaran 29 dari 31.

Lewat pintu ruangan terakhir, ksatria berhasil keluar: game menampilkan You escaped!. Setelah salah satu dari kedua akhir, tekan R untuk memulai lagi di ruangan pertama.

Sekarang, pengujian pintu memiliki dua hasil:

if room.door_open and knight.rect.colliderect(room.door):
    if level == len(ROOMS) - 1:
        state = "won"
    else:
        level += 1
        room = Room(ROOMS[level])
        knight.rect.center = room.start

Memulai lagi hanya memerlukan sedikit kode karena class menampung game. Room baru membangun ulang ruangan pertama dengan kunci, pintu, dan semua slime kembali ke tempatnya. Knight baru memiliki 3 hati, tidak terluka, dan tidak sedang mengayunkan senjata.

elif event.key == pygame.K_r and state != "playing":
    level = 0
    room = Room(ROOMS[level])
    knight = Knight(room.start)
    state = "playing"

Mainkan dari awal. Jika sebuah ruangan terlalu sulit atau terlalu cepat, ubah peta: pindahkan slime, tambahkan ramuan, gambar ruangan baru, lalu tambahkan ke ROOMS. Tidak ada hal lain yang perlu diubah karena setiap aturan membaca peta. Slime di koridor selebar satu tile tidak bisa dilewati, jadi harus dilawan; slime di aula terbuka bisa dihindari.

Tantangan

Sedang

Ubah pemeriksaan pintu seperti di atas: di ruangan terakhir, atur state menjadi "won".
Saat state bernilai "won", tampilkan You escaped! di tengah pada (336, 240).
Setelah salah satu akhir permainan, tampilkan Press R to play again di tengah pada (336, 290).
Tekan R saat state bukan "playing" untuk memulai lagi seperti di atas, menggunakan KEYDOWN.
