なぜint型にint型を代入しようとするとエラーが発生してしまうのでしょうか。

エラーメッセージを見る限り配列を入れようとしているんじゃないんですか？

Answer 1

Assets\Scripts\Player.cs(137,23): error CS0029: Cannot implicitly convert type 'int[]' to 'int'

Player.csの137行目23文字の場所でint[]をintにキャスト(変換)できませんというエラーです。

137行目は

        p_Item_num1 = GameManager.Instance.Item_num;

ですが、23文字目以降のGameManager.Instance.Item_num がint[]のせいと推測されます。

原因となっているGameManagerはあなたの書かれた別のコードですので
そちらを直すべきなのかこのコードを直すべきかはこれだけでは判断できません。
