Assets/Player.cs(30,21): error CS1061: 'Rigidbody2D' does not contain a definition for 'Moveposition' and no accessible extension method 'Moveposition' accepting a first argument of type 'Rigidbody2D' could be found (are you missing a using directive or an assembly reference?)

どこか構文が間違ってると思うんですがどこがエラーかわからないためわかる方いましたら教えてください。
