RaycastHit2D[] The cast results returned.
Casts a ray against colliders in the Scene, returning all colliders that contact with it.
BoxCast, концептуально, это как протягивание коробки сквозь сцену в определенном направлении. Любой объект, вступающий в контакт с коробкой, может быть обнаружен и зарегистрирован.
This function is similar to the Raycast function but instead of detecting just the first collider that is hit, an array of all colliders along the path of the ray is returned. The colliders in the array are sorted in order of distance from the origin point. The layerMask can be used to detect objects selectively only on certain layers (this allows you to apply the detection only to enemy characters, for example).
Raycasts are useful for determining lines of sight, targets hit by gunfire and for many other purposes in gameplay.
Additionally, this will also detect Collider(s) at the start of the ray. In this case, the ray starts inside the Collider and doesn't intersect the Collider surface. This means that the collision normal cannot be calculated, in which case the returned collision normal is set to the inverse of the ray vector being tested. This can easily be detected because such results are always at a RaycastHit2D fraction of zero.
