画像とPygameのオブジェクトとの衝突検出

Question

皆さんはすばらしい一日を過ごしたいと願っています。
オブジェクト（黒い四角形）と食べ物の画像の衝突を検出しようとしています。
私は基本的に何をしたいのですか？長方形が食べ物の画像と衝突し、食べ物の画像がランダムに画面に配置され、スコアが+1増加すると、いつでもそうなります。 drawcellで

（）の呼び出し：

if makecell.colliderect(foodrect): 
    foodrect.x = random.randint(0, sceeenwidth) 
    foodrect.y = random.randint(0, screenheight) 

はそれを行う必要があります。
