<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].

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.
