Struct bevy_mod_picking::RayCastSource

source · [−]

pub struct RayCastSource<T> {
    pub cast_method: RayCastMethod,
    pub ray: Option<Ray3d>,
    /* private fields */
}

Expand description

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: RayCastMethodray: Option<Ray3d>

Implementations

source

impl<T> RayCastSource<T>

source

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.

source

pub fn with_ray_screenspace(
 self,
 cursor_pos_screen: Vec2,
 camera: &Camera,
 camera_transform: &GlobalTransform
) -> RayCastSource<T>

Initializes a RayCastSource with a valid screenspace ray.

source

pub fn with_ray_transform(self, transform: Mat4) -> RayCastSource<T>

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

source

pub fn new_screenspace(
 cursor_pos_screen: Vec2,
 camera: &Camera,
 camera_transform: &GlobalTransform
) -> RayCastSource<T>

Instantiates and initializes a RayCastSource with a valid screenspace ray.

source

pub fn new_transform(transform: Mat4) -> RayCastSource<T>

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

source

pub fn new_transform_empty() -> RayCastSource<T>

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.

source

pub fn intersect_list(&self) -> Option<&Vec<(Entity, IntersectionData), Global>>

source

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

source

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

source

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

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

source

pub fn intersections_mut(
&mut self
) -> &mut Vec<(Entity, IntersectionData), Global>ⓘNotable traits for Vec<u8, A>`impl<A> Write for Vec<u8, A> where A: Allocator,`

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