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.
