A raycast is conceptually like a laser beam that is fired from a point in space along a particular direction. Any object making contact with the beam can be detected and reported. This function returns a RaycastHit2D object with a reference to the Collider that is hit by the ray 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. Overloads of this method that use contactFilter can filter the results by the options available in ContactFilter2D.

Raycasting is often the subject of heated debate in tutorials, forums, and blogs.

You may optionally provide a LayerMask , to filter out any Colliders you aren't interested in generating collisions with. If true is returned, hitInfo will contain more information about where the closest collider was hit. Returns bool Returns true when the ray intersects any collider, otherwise false.
