rect | 内部の点を見つけるための RectTransform。 |
cam | スクリーン空間位置に関連するカメラ。 |
screenPoint | スクリーン空間位置。 |
localPoint | Rect Transform のローカル空間でのポイント。 |
bool RectTransform の平面がヒットした場合、ポイントが矩形の内側にあるかは関係なく true を返します。
スクリーン空間ポイントを、矩形の平面上にある RectTransform のローカル空間の位置に変換します。
cam 引数は、スクリーン空間位置に関連するカメラである必要があります。スクリーン空間として設定した Canvas の RectTransform については、オーバーレイモードやカメラパラメーターは null にしなければなりません。
ScreenPointToLocalPointInRectangle が PointerEventData オブジェクトを提供するイベントハンドラ内で利用されるとき、PointerEventData.enterEventCamera (hover 機能向け) や PointerEventData.pressEventCamera (click 機能向け)を使用することによって正しいカメラを取得することができます。このとき所定のイベント向けに自動的に選ばれた適切なカメラ(と null のどちらか)を使用します。
