Jatuh keluar dari level

Termasuk bagian Dunia Game dalam perjalanan Pygame di Coddy. Pelajaran 18 dari 35.

Tanah memiliki lubang. Berjalanlah ke dalamnya, lalu pemain akan jatuh selamanya hingga tidak terlihat. Nilai y-nya terus bertambah dan tidak ada yang membawanya kembali.

Level berakhir di bagian bawah jendela, y = 360. Setelah bagian atas pemain melewati batas itu, seluruh tubuhnya berada di luar level: kembalikan ke titik awal dan hentikan jatuhnya.

if player.top > 360:
    player.midbottom = start
    vel_y = 0

start adalah titik yang disimpan oleh perulangan peta untuk tile P: bagian tengah bawah tile itu, tempat pemain pertama kali berdiri. Nanti, nyawa akan hilang di sini.

Tantangan

Mudah

Setel player.midbottom = start dan vel_y = 0 setelah tabrakan vertikal, saat player.top > 360.
