- <brief_description>
- Query the closest object intersecting a ray.
- </brief_description>
- <description>
- 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] or by setting proper filtering with collision layers and masks.
- RayCast can be configured to report collisions with [Area]s ([member collide_with_areas]) and/or [PhysicsBody]s ([member collide_with_bodies]).
- Only enabled raycasts will be able to query the space and report collisions.
- RayCast 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.

- <methods>
- <method name="add_exception">
- <return type="void">
- </return>
- <argument index="0" name="node" type="Object">
- </argument>
- <description>
- Adds a collision exception so the ray does not report collisions with the specified node.
- </description>
- </method>
- <method name="add_exception_rid">
- <return type="void">
- </return>
- <argument index="0" name="rid" type="RID">
- </argument>
- <description>
- Adds a collision exception so the ray does not report collisions with the specified [RID].
- </description>
- </method>
- <method name="clear_exceptions">
- <return type="void">
- </return>
- <description>
- Removes all collision exceptions for this ray.
- </description>
- </method>
- <method name="force_raycast_update">
- <return type="void">
- </return>
- <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] [code]enabled == true[/code] is not required for this to work.

- </method>
- <method name="get_collider" qualifiers="const">
- <return type="Object">
- </return>
- <description>
- Returns the first object that the ray intersects, or [code]null[/code] if no object is intersecting the ray (i.e. [method is_colliding] returns [code]false[/code]).
- </description>
- </method>
- <method name="get_collider_shape" qualifiers="const">
- <return type="int">
- </return>
- <description>
- Returns the shape ID of the first object that the ray intersects, or [code]0[/code] if no object is intersecting the ray (i.e. [method is_colliding] returns [code]false[/code]).

- <method name="get_collision_mask_bit" qualifiers="const">
- <return type="bool">

- </description>
- </method>
- <method name="get_collision_normal" qualifiers="const">

- <description>
- Returns the normal of the intersecting object's shape at the collision point.
- </description>
- </method>
- <method name="get_collision_point" qualifiers="const">
- <return type="Vector3">
- </return>
- <description>
- Returns the collision point at which the ray intersects the closest object.

- </description>
- </method>
- <method name="is_colliding" qualifiers="const">
- <return type="bool">
- </return>
- <description>
- Returns whether any object is intersecting with the ray's vector (considering the vector length).
