if文を使って色を変化させたい

前提・実現したいこと

簡単なゲームを作ろうとしています。プレイヤーとcheckポイントを設定してもしそのプレイヤーがチェックポイントの上に重なるとcheckポイントの色が変化するようにしたいです。checkポイントを設定して表示するとこまではできたのですが色を変化させる段階で自分なりにif文を追加してみたのですが行き詰ってしまい質問させていただきました。初心者のためつたないプログラムだとは思いますがどなたかご教授いただけると幸いです。

発生している問題・エラーメッセージ

座標指定にsetBoundsというものを利用したのですがその部分でvoidをbooleanに変換できませんというエラーが出ています。

試したこと

if文としてこの部分を追加しました。

if (player.setBounds(260, 260, LENGTH_OF_CHECKPOINT, LENGTH_OF_CHECKPOINT)){
              Image screen = createImage(FRAME_LENGTH, FRAME_LENGTH);
              Graphics2D g = (Graphics2D) screen.getGraphics();
              g.setColor(Color.white);
              g.draw(checkpoint2);
              }
          if (player.setBounds(260, 200, LENGTH_OF_CHECKPOINT, LENGTH_OF_CHECKPOINT)){
              Image screen = createImage(FRAME_LENGTH, FRAME_LENGTH);
              Graphics2D g = (Graphics2D) screen.getGraphics();
              g.setColor(Color.white);
              g.draw(checkpoint3);
              }
          if (player.setBounds(10, 200, LENGTH_OF_CHECKPOINT, LENGTH_OF_CHECKPOINT)){
              Image screen = createImage(FRAME_LENGTH, FRAME_LENGTH);
              Graphics2D g = (Graphics2D) screen.getGraphics();
              g.setColor(Color.white);
              g.draw(checkpoint1);
              }
          if (player.setBounds(10, 50, LENGTH_OF_CHECKPOINT, LENGTH_OF_CHECKPOINT)){
