こんにちはi`veが問題だ：彼らは私がGraphics2DObject.clearRectを追加する必要があると述べたいくつかのJavaフォーラム（X1、Y1にJavaの動くアニメーション（スプライト）
：私はこのコードを実行したときに私はこれを取得します、x2、y2）。 （X1とY1は、画像の幅、高さ画像及びX2、Y2の座標であるwhere`s。）私はこれを取得するコードに追加：

EDIT：
誰かがこのコードを実行してみてくださいもらえますか？
たぶんあなたは、私が犯した過ちを見つけることができます...
スプライト（または複雑な環境）が2つある場合は可能な限り画面全体をクリアしないようにしてください。ただし、悲しいです。 – ClickerMonkey
はい、ClickerMonkeyが正しいです。私はOPが何かを複雑にしようとしていたという印象を受けました。 –
