pygameで三角衝突を起こすには？

Question

私はpygameでplatformerを作ろうとしており、私は問題を見つけました。私は簡単に四角形と四角形の衝突を作ることができますが、私は直角三角形に対してはできません。 pygameを使ってこれを行うことも可能ですか？私はコーナーの1つを取り除くことを考えましたが、これを行う方法を知らず、どこでも役に立つ情報を見つけることができません。 1人の人間がより小さな四角い衝突を使用して三角衝突を起こすことを示唆していましたが、これは望みの効果を与えませんでした。次のコードが他の人によって作られたが、それは基本的に私のと同じでありました、唯一の違いは私はアニメーションなどを持っていると私はそれがすることはできませんなど

ジャンプ物理学の数値の一部を変更しましたPygameモジュールメソッドで三角衝突を実装します。しかし、Pylygonモジュールについて調べる。
