public bool SweepTest (Vector3 direction, out RaycastHit hitInfo, float maxDistance= Mathf.Infinity, QueryTriggerInteraction queryTriggerInteraction= QueryTriggerInteraction.UseGlobal);

パラメーター

direction リジッドボディをスイープする方向。
hitInfo true が返されたときhitInfo はヒットしたコライダーについての情報が含まれています。(関連項目: RaycastHit)
maxDistance スイープの長さ。
queryTriggerInteraction トリガーに設定されているものも検索対象にするか

戻り値

bool リジッドボディが他のコライダーを横切ってスイープする場合は true を返します。その他の場合は false を返します。

説明

Tests if a rigidbody would collide with anything, if it was moved through the Scene.

Tests if a rigidbody would collide with anything, if it was moved through the Scene. This is similar to doing a Physics.Raycast for all points contained in any of a Rigidbody's colliders and returning the closest of all hits (if any) reported. This is useful for AI code, say if you need to know that an object would fit through a gap without colliding with anything.

Note that this function only works when a primitive collider type (sphere, cube or capsule) or a convex mesh is attached to the rigidbody object - concave mesh colliders will not work, although they can be detected in the Scene by the sweep.
