パラメーター

selectPrefabRoot	Select Prefab.
materialIndex	指定されたポジションに最も近い Renderer コンポーネントのマテリアル配列にインデックスを返します。
position	A position in screen coordinates. The top-left of the window is (0,0), and the bottom-right is (Screen.width, Screen.height).
ignore	An array of GameObjects that will not be considered when selecting the nearest GameObject.
filter	An array of GameObjects to be exclusively considered for selection. If null, all GameObjects in open scenes are eligible for selection.
selection	An array of GameObjects to be exclusively considered for selection. If null, all GameObjects in open scenes are eligible for selection.

戻り値

GameObject The GameObject that is under the requested position.

説明

指定したポジションに最も近いゲームオブジェクトを選択します。

HandleUtility.PickGameObject must not be called during a repaint. In most cases it is appropriate to call during EventType.MouseDown or EventType.MouseUp.
