戻り値

RaycastHit[] 通過で衝突した全コライダーの配列

説明

Physics.CapsuleCast のようですが、この関数はヒットしたすべての情報を取得します

Casts a capsule against all colliders in the scene and returns detailed information on each collider which was hit. The capsule is defined by the two spheres with radius around point1 and point2, which form the two ends of the capsule. Hits are returned all colliders which would collide against this capsule if the capsule was moved along direction. This is useful when a Raycast does not give enough precision, because you want to find out if an object of a specific size, such as a character, will be able to move somewhere without colliding with anything on the way.

Notes: For colliders that overlap the capsule at the start of the sweep, RaycastHit.normal is set opposite to the direction of the sweep, RaycastHit.distance is set to zero, and the zero vector gets returned in RaycastHit.point. You might want to check whether this is the case in your particular query and perform additional queries to refine the result.
