<brief_description>
A ray in 3D space, used to find the first [CollisionObject3D] it intersects.
</brief_description>
<description>
A raycast represents a ray from its origin to its [member target_position] that finds the closest [CollisionObject3D] along its path, if it intersects any. This is useful for a lot of things, such as
[RayCast3D] can ignore some objects by adding them to an exception list, by making its detection reporting ignore [Area3D]s ([member collide_with_areas]) or [PhysicsBody3D]s ([member collide_with_bodies]), or by configuring physics layers.
[RayCast3D] calculates intersection every physics frame, and it holds the result until the next physics frame. For an immediate raycast, or if you want to configure a [RayCast3D] multiple times within the same physics frame, use [method force_raycast_update].
To sweep over a region of 3D space, you can approximate the region with multiple [RayCast3D]s or use [ShapeCast3D].

<methods>
<method name="add_exception">
<return type="void" />
<param index="0" name="node" type="CollisionObject3D" />
<description>
Adds a collision exception so the ray does not report collisions with the specified [CollisionObject3D] node.
</description>
</method>
<method name="add_exception_rid">
<return type="void" />
<param index="0" name="rid" type="RID" />
<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" />
<description>
Removes all collision exceptions for this ray.
</description>
</method>
<method name="force_raycast_update">
<return type="void" />
<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.
</description>
</method>
<method name="get_collider" qualifiers="const">
<return type="Object" />
<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_rid" qualifiers="const">
<return type="RID" />
<description>
Returns the [RID] of the first object that the ray intersects, or an empty [RID] 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" />
<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]).
</description>
</method>
<method name="get_collision_mask_value" qualifiers="const">
<return type="bool" />
<param index="0" name="layer_number" type="int" />
<description>
Returns whether or not the specified layer of the [member collision_mask] is enabled, given a [param layer_number] between 1 and 32.
</description>
</method>
<method name="get_collision_normal" qualifiers="const">
<return type="Vector3" />
<description>
Returns the normal of the intersecting object's shape at the collision point, or [code]Vector3(0, 0, 0)[/code] if the ray starts inside the shape and [member hit_from_inside] is [code]true[/code].
</description>
</method>
<method name="get_collision_point" qualifiers="const">
<return type="Vector3" />
<description>
Returns the collision point at which the ray intersects the closest object.
[b]Note:[/b] This point is in the [b]global[/b] coordinate system.
</description>
</method>
<method name="is_colliding" qualifiers="const">
<return type="bool" />
<description>
Returns whether any object is intersecting with the ray's vector (considering the vector length).
</description>
</method>
<method name="remove_exception">
<return type="void" />
<param index="0" name="node" type="CollisionObject3D" />
<description>
Removes a collision exception so the ray does report collisions with the specified [CollisionObject3D] node.
</description>
</method>
<method name="remove_exception_rid">
<return type="void" />
<param index="0" name="rid" type="RID" />
<description>
Removes a collision exception so the ray does report collisions with the specified [RID].
</description>
</method>
<method name="set_collision_mask_value">
<return type="void" />
<param index="0" name="layer_number" type="int" />
<param index="1" name="value" type="bool" />
<description>
Based on [param value], enables or disables the specified layer in the [member collision_mask], given a [param layer_number] between 1 and 32.

</member>
<member name="collision_mask" type="int" setter="set_collision_mask" getter="get_collision_mask" default="1">
