Query the closest object intersecting a ray.

</brief_description>

<description>
|
|
A RayCast represents a line from its origin to its destination position, [member target_position]. It is used to query the 2D space in order to find the closest object along the path of the ray.
|
|
RayCast2D can ignore some objects by adding them to the exception list via [method add_exception], by setting proper filtering with collision layers, or by filtering object types with type masks.
|
|
RayCast2D can be configured to report collisions with [Area2D]s ([member collide_with_areas]) and/or [PhysicsBody2D]s ([member collide_with_bodies]).
|
|
Only enabled raycasts will be able to query the space and report collisions.
|
|
RayCast2D calculates intersection every physics frame (see [Node]), and the result is cached so it can be used later until the next frame. If multiple queries are required between physics frames (or during the same frame) use [method force_raycast_update] after adjusting the raycast.

|
<description>
|
|
Updates the collision information for the ray. Use this method to update the collision information immediately instead of waiting for the next [code]_physics_process[/code] call, for example if the ray or its parent has changed state.
|
|
[b]Note:[/b] [member enabled] does not need to be [code]true[/code] for this to work.
