See in Glossary needs a method for detecting where current input events need to be sent to, and this is provided by the Raycasters.

There are a few types of Raycasters that are provided:
When a Raycaster is present and enabled in the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary it will be used by the Event System whenever a query is issued from an Input Module.
If multiple Raycasters are used then they will all have casting happen against them and the results will be sorted based on distance to the elements.
