| Parameter | Description |
|---|---|
| hit | The RaycastHit2D to being checked for valid results. |
Description
Implicit operator used to return a true or false result indicating if the result is valid or not.
When using any physics query that returns a RaycastHit2D, you should always first check to see if it contains a valid result which indicates a hit (intersection) was detected. You can do this by checking if the RaycastHit2D is true or false.
NOTE: A valid result is indicated by the field RaycastHit2D.Collider referring to a valid Collider2D i.e. not being NULL. This operator is therefore equivalent to checking if that field is NULL ( false ) or not NULL ( true ).
