+		A RayCast represents a line from its origin to its destination position, [code]cast_to[/code]. It is used to query the 3D space in order to find the closest object along the path of the ray.
 
-		RayCast can ignore some objects by adding them to the exception list via [code]add_exception[/code], setting proper filtering with layers, or by filtering object types with type masks.

+		Only enabled raycasts will be able to query the space and report collisions.
 
 		RayCast calculates intersection every fixed frame (see [Node]), and the result is cached so it can be used later until the next frame. If multiple queries are required between fixed frames (or during the same frame) use [method force_raycast_update] after adjusting the raycast.
