Hit-testing is the process of finding elements of a scene located along a specified line segment in the scene’s coordinate space (or that of a particular node in the scene). For example, you can use this method to determine whether a projectile launched by a game character will hit its target.
To search for the scene element corresponding to a two-dimensional point in the rendered image, use the renderer’s
hit method instead.
