-==== Implicit Bool Casting Magic ==== +==== Casts Implicitly To a Bool ==== 
- +RaycastHit2D implements the C# [[https://forum.unity.com/threads/c-beginner-tips-1-your-friend-the-implicit-bool.185761/|implicit bool]] operator. This allows it to be used in an if statement to check whether a hit is found
-''RaycastHit2D'' can be used in an if statement to tell if the raycast hit anything, or if it hit nothing. +++++ Example | 
-This is because C# has the ability to do implied type conversions, and Unity has made it so RaycastHit2D can be converted to a boolPretty cool. +<code c#>

-Example: +
-<code>+
 RaycastHit2D hit = Physics2D.Raycast(someStartPoint, someDirection); RaycastHit2D hit = Physics2D.Raycast(someStartPoint, someDirection);
