RaycastHit2D The cast results returned.
Casts a box against colliders in the Scene, returning the first collider to contact with it.
A BoxCast is conceptually like dragging a box through the Scene in a particular direction. Any object making contact with the box can be detected and reported.
This function returns a RaycastHit2D object with a reference to the collider that is hit
by the box (the collider property of the result will be NULL if nothing was hit). 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).
The returned RaycastHit2D returns both the point and normal of the contact where the box
would touch the collider. It also returns the centroid where the box would be positioned
for it to contact at that point.
BoxCast has a size option. This defines how large the box is. The box is fired
through the world. The larger the box is the more GameObjects will be hit.
BoxCast also has a angle option. The box which is fired through the elements in
the game can be rotated. This means that the collision between the BoxCast and a GameObject
can be more hard to observe.
The BoxCast.direction variable determines how the Box moves in the Game. This
is a 2D variable controlling the horizontal and vertical directions.
Distance controls how far from the origin the Box travels. It may interact with
many Colliders or none. In these cases the closest Collider2D provides the values set in
the RaycastHit2D variable. If no Collider2D is hit then NULL is returned.

int
Returns the number of results placed in the results array.
Casts a box against the Colliders in the Scene and returns all Colliders that are in contact with it.
A BoxCast is conceptually like dragging a box through the Scene in a particular direction. Any Collider making contact with the box can be detected and reported.
This function returns the number of contacts found and places those contacts in the results array. The results can also be filtered by the contactFilter.

void
Returns the number of results placed in the results list.
Casts a box against the Colliders in the Scene and returns all Colliders that are in contact with it.
A BoxCast is conceptually like dragging a box through the Scene in a particular direction. Any Collider making contact with the box can be detected and reported.
The integer return value is the number of results written into the results list. The results list will be resized if it doesn't contain enough elements to report all the results. This prevents memory from being allocated for results when the results list does not need to be resized, and improves garbage collection performance when the query is performed frequently.
The results can also be filtered by the contactFilter.
