Collider2D The collider overlapping the area.
Checks if a collider falls within a rectangular area.
矩形はワールド座標で反対向きの斜め座標により定義されます。左上と右下の隅と考えていいですが、順番を逆にしても動作します。オプションとして layerMask 設定することで特定レイヤーのオブジェクトのみ判定できます。
2D のレンダリングと衝突において Z 軸は無関係であるもの、minDepth や maxDepth パラメーターを使用することで Z 軸にもとづいてオブジェクトをフィルタリングすることができます。もし一つ以上のコライダーが点を含む場合はもっとも小さい Z 座標の値を持ったものが返されます。また点を含むコライダーがない場合は null が返されます。

int
Returns the number of results placed in the results array.
Checks if a collider falls within a rectangular area.
The rectangle is defined by two diagonally opposite corner coordinates in world space. You can think of these as top-left and bottom-right but the test will still work if the ordering of the points is reversed.
This function returns the number of colliders found and places those colliders in the results array. The results can also be filtered by the contactFilter. Note that filtering by normal angle is not available for overlap functions.

Checks if a Collider falls within a rectangular area.
The rectangle is defined by two diagonally opposite corner coordinates in world space. You can think of these as top-left and bottom-right but the test will still work if the ordering of the points is reversed.
The integer return value is the number of results written into the results list. The results list will be resized if it doesn't contain enough elements to report all the results. This prevents memory from being allocated for results when the results list does not need to be resized, and improves garbage collection performance when the query is performed frequently.
The results can also be filtered by the contactFilter.
Note that filtering by normal angle is not available for overlap functions.
