私の衝突検出は機能しているようですが、検出されている衝突のいくつかは奇妙ですが、そうでないときに衝突がプラットフォームの底にあったと言うようです。しかし、それは主な問題ではありません。
プレイヤーがプラットフォームに衝突すると、プラットフォームの表面に移動するのではなく、プラットフォームの上に移動し、私の重力が適所にあるため、常にバウンドしているように見えます。理由がわかりません。
あなたたちが助けてくれれば、それは大歓迎です。私は XNA と C# を初めて使用するので、見逃している非常に単純なものである可能性があります。
以下に、私の Game1、Player、および Platform クラスをリストします。（私の衝突検出はプレーヤークラスにあります）
ありがとう
