Struct bevy_mod_raycast::deferred::RaycastSource

pub struct RaycastSource<T: TypePath> {
    pub cast_method: RaycastMethod,
    pub should_early_exit: bool,
    pub visibility: RaycastVisibility,
    pub ray: Option<Ray3d>,
    /* private fields */
}

The RaycastSource component is used to generate rays with the specified cast_method. A ray is generated when the RaycastSource is initialized, either by waiting for update_raycast system to process the ray, or by using a with_ray function.`

Fields

cast_method: RaycastMethod

The method used to generate rays for this raycast.

should_early_exit: bool

When true, raycasting will only hit the nearest entity, skipping any entities that are further away. This can significantly improve performance in cases where a ray intersects many AABBs.

visibility: RaycastVisibility

Determines how raycasting should consider entity visibility.

ray: Option<Ray3d>

Implementations

impl<T: TypePath> RaycastSource<T>

pub fn new() -> RaycastSource<T>

Instantiates a RaycastSource. It will not be initialized until the update_raycast system runs, or one of the with_ray functions is run.

pub fn with_ray_screenspace( self, cursor_pos_screen: Vec2, camera: &Camera, camera_transform: &GlobalTransform, window: &Window ) -> Self

Initializes a RaycastSource with a valid screenspace ray.

pub fn with_ray_transform(self, transform: Mat4) -> Self

Initializes a RaycastSource with a valid ray derived from a transform.

pub fn with_early_exit(self, should_early_exit: bool) -> Self

Set the should_early_exit field of this raycast source.

pub fn with_visibility(self, visibility: RaycastVisibility) -> Self

Set the visibility field of this raycast source.

pub fn new_screenspace( cursor_pos_screen: Vec2, camera: &Camera, camera_transform: &GlobalTransform, window: &Window ) -> Self

Instantiates and initializes a RaycastSource with a valid screenspace ray.

pub fn new_cursor() -> Self

Initializes a RaycastSource for cursor raycasting.

pub fn new_transform(transform: Mat4) -> Self

Initializes a RaycastSource with a valid ray derived from a transform.

pub fn new_transform_empty() -> Self

Instantiates a RaycastSource with RaycastMethod::Transform, and an empty ray. It will not be initialized until the update_raycast system is run and a GlobalTransform is present on this entity.

Warning

Only use this if the entity this is associated with will have its Transform or GlobalTransform specified elsewhere. If the GlobalTransform is not set, this ray casting source will never be able to generate a raycast.

pub fn get_intersections(&self) -> Option<&[(Entity, IntersectionData)]>

Get a reference to the ray cast source’s intersections, if one exists.

pub fn intersections(&self) -> &[(Entity, IntersectionData)]

Get a reference to the ray cast source’s intersections. Returns an empty list if there are no intersections.

pub fn get_nearest_intersection(&self) -> Option<(Entity, &IntersectionData)>

Get a reference to the nearest intersection point, if there is one.

pub fn intersect_primitive( &self, shape: Primitive3d ) -> Option<IntersectionData>

Run an intersection check between this RaycastSource and a 3D primitive Primitive3d.

pub fn get_ray(&self) -> Option<Ray3d>

Get a copy of the ray cast source’s ray.

pub fn intersections_mut(&mut self) -> &mut Vec<(Entity, IntersectionData)>

Get a mutable reference to the ray cast source’s intersections.

pub fn is_screenspace(&self) -> bool

Returns true if this is using RaycastMethod::Screenspace.
