direction | A vector representing the direction of the circle. |
results | 結果を受け取る配列 |
distance | The maximum distance over which to cast the circle. |

int
Returns the number of results placed in the results
array.
Casts a circle into the Scene, returning Colliders that contact with it into the provided results array. Note: This method will be deprecated in a future build and it is recommended to use CircleCast instead.
この関数は結果が配列に返されること以外は CircleCastAll 関数と同様です。返される int 値は円形と交わるオブジェクトの数です( 0 の可能性もあります)が、オブジェクトの数が配列よりも多くとも配列の長さが変わることはありません。この仕様について重要なのは、この結果からメモリ割り当てが行われないため、頻繁に実行された場合にガベージコレクションのパフォーマンスが向上するということです。
The returned RaycastHit2D returns both the point and normal of the contact where the circle would touch the Collider. It also returns the centroid where the circle would be positioned for it to contact at that point.
