Rigidbody.SweepTestのようですが、これはヒットした全てを返します
The sweep may return multiple hits against the same collider if more then one of the rigidbody's attached colliders would hit it. Note that this function only works when a primitive collider type (sphere, cube or capsule) is attached to the rigidbody object - mesh colliders will not work, although they can be detected in the scene by the sweep.
