boolが他のスクリプトに正しく渡されていない？

unity2dでPlayerにRaycastが当たっていないときにfalse、当たっているときはtrueをスクリプトsurpriseに渡すプログラムを書こうとしたのですがうまくいかなかっため(Debug.Logすら出ない)、unity3dで簡易的なものをつくってみたところ問題なく渡せたので何がいけなかったのかがわからなくて困っています。お手数をおかけしますがご教示いただけますでしょうか。

---確認したこと---
GameObject.Find("")の名前が間違っていないかどうか
→Inspectorからコピペして貼ったので間違うことはないはず
if (hit2D.collider.tag == "Player" && hit2D.distance < 10f)が通らないのでは
→Debug.Logで確認しましたが問題なかったです
found_Flagですべての参照を検索
→bool bikkuri = found.found_Flag;がでてきたので問題ないはず

enemy_MoveのDiscovery()がRaycastの描画でUpdateの上から３行目のところで呼び出しています
