プレイヤーが剣を持っているプラットフォーマー ゲームに取り組んでいます。私は、プレイヤーが彼の下に地面がある場合にのみ攻撃できるようにしたい (したがって、彼は空中で攻撃できない)。だから私はこのコードを実装しました：
for b in instancelist:
for p in players:
if b.rect.collidepoint(p.rect.centerx,p.rect.bottom+4):
grounded=1
else:
grounded=0
print grounded
しかし..
print grounded
毎回ゼロを返します..exit(1)プレイヤーが地面にいることをテストする部分に追加しても、それでも終了します! （接地はまだゼロに等しい間）
コード全体は次のとおりです。
