Struct gdnative_bindings_lily::ray_cast::RayCast

pub struct RayCast { /* fields omitted */ }

core class RayCast inherits Spatial (unsafe).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Memory management

Non reference counted objects such as the ones of this type are usually owned by the engine.

RayCast is a reference-only type. Persistent references can only exist in the unsafe Ref<RayCast> form.

In the cases where Rust code owns an object of this type, for example if the object was just created on the Rust side and not passed to the engine yet, ownership should be either given to the engine or the object must be manually destroyed using Ref::free, or Ref::queue_free if it is a Node.

Class hierarchy

RayCast inherits methods from:

• Spatial
• Node
• Object

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl RayCast

pub fn new() -> Ref<Self, Unique>

Creates a new instance of this object.

Because this type is not reference counted, the lifetime of the returned object is not automatically managed.

Immediately after creation, the object is owned by the caller, and can be passed to the engine (in which case the engine will be responsible for destroying the object) or destroyed manually using Ref::free, or preferably Ref::queue_free if it is a Node.

pub fn add_exception(&self, node: impl AsArg<Object>)

Adds a collision exception so the ray does not report collisions with the specified node.

pub fn add_exception_rid(&self, rid: Rid)

Adds a collision exception so the ray does not report collisions with the specified [RID].

pub fn clear_exceptions(&self)

Removes all collision exceptions for this ray.

pub fn force_raycast_update(&self)

Updates the collision information for the ray. Use this method to update the collision information immediately instead of waiting for the next _physics_process call, for example if the ray or its parent has changed state. Note: enabled is not required for this to work.

pub const NOTIFICATION_ENTER_WORLD: i64

pub const NOTIFICATION_EXIT_WORLD: i64

pub const NOTIFICATION_TRANSFORM_CHANGED: i64

pub const NOTIFICATION_VISIBILITY_CHANGED: i64

pub fn force_update_transform(&self)

Forces the transform to update. Transform changes in physics are not instant for performance reasons. Transforms are accumulated and then set. Use this if you need an up-to-date transform when doing physics operations.

pub fn gizmo(&self) -> Option<Ref<SpatialGizmo, Shared>>

The SpatialGizmo for this node. Used for example in EditorSpatialGizmo as custom visualization and editing handles in Editor.

pub fn global_transform(&self) -> Transform

World space (global) Transform of this node.

pub fn get_parent_spatial(&self) -> Option<Ref<Spatial, Shared>>

Returns the parent Spatial, or an empty Object if no parent exists or parent is not of type Spatial.

pub fn rotation(&self) -> Vector3

Rotation part of the local transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle). Note: In the mathematical sense, rotation is a matrix and not a vector. The three Euler angles, which are the three independent parameters of the Euler-angle parametrization of the rotation matrix, are stored in a Vector3 data structure not because the rotation is a vector, but only because Vector3 exists as a convenient data-structure to store 3 floating-point numbers. Therefore, applying affine operations on the rotation “vector” is not meaningful.

pub fn rotation_degrees(&self) -> Vector3

Rotation part of the local transformation in degrees, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).

pub fn scale(&self) -> Vector3

Scale part of the local transformation.

pub fn transform(&self) -> Transform

Local space Transform of this node, with respect to the parent node.

pub fn translation(&self) -> Vector3

Returns the current World resource this Spatial node is registered to.

pub fn global_rotate(&self, axis: Vector3, angle: f64)

Rotates the global (world) transformation around axis, a unit Vector3, by specified angle in radians. The rotation axis is in global coordinate system.

pub fn is_transform_notification_enabled(&self) -> bool

Returns whether the node notifies about its global and local transformation changes. Spatial will not propagate this by default.

If true, this node is drawn. The node is only visible if all of its antecedents are visible as well (in other words, [method is_visible_in_tree] must return true).

pub fn is_visible_in_tree(&self) -> bool

Returns true if the node is present in the SceneTree, its [member visible] property is true and all its antecedents are also visible. If any antecedent is hidden, this node will not be visible in the scene tree.

pub fn look_at(&self, target: Vector3, up: Vector3)

Rotates itself so that the local -Z axis points towards the target position. The transform will first be rotated around the given up vector, and then fully aligned to the target by a further rotation around an axis perpendicular to both the target and up vectors. Operations take place in global space.

pub fn look_at_from_position(
    &self,
    position: Vector3,
    target: Vector3,
    up: Vector3
)

Rotates the local transformation around axis, a unit Vector3, by specified angle in radians.

pub fn rotate_object_local(&self, axis: Vector3, angle: f64)

pub fn set_global_transform(&self, global: Transform)

World space (global) Transform of this node.

pub fn set_identity(&self)

Reset all transformations for this node (sets its Transform to the identity matrix).

pub fn set_ignore_transform_notification(&self, enabled: bool)

Sets whether the node ignores notification that its transformation (global or local) changed.

pub fn set_notify_local_transform(&self, enable: bool)

Sets whether the node notifies about its local transformation changes. Spatial will not propagate this by default.

pub fn set_notify_transform(&self, enable: bool)

Sets whether the node notifies about its global and local transformation changes. Spatial will not propagate this by default.

pub fn set_rotation(&self, euler: Vector3)

Rotation part of the local transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle). Note: In the mathematical sense, rotation is a matrix and not a vector. The three Euler angles, which are the three independent parameters of the Euler-angle parametrization of the rotation matrix, are stored in a Vector3 data structure not because the rotation is a vector, but only because Vector3 exists as a convenient data-structure to store 3 floating-point numbers. Therefore, applying affine operations on the rotation “vector” is not meaningful.

pub fn set_rotation_degrees(&self, euler_degrees: Vector3)

Rotation part of the local transformation in degrees, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).

pub fn set_scale(&self, scale: Vector3)

Local space Transform of this node, with respect to the parent node.

pub fn set_translation(&self, translation: Vector3)

Local translation of this node.

pub fn set_visible(&self, visible: bool)

If true, this node is drawn. The node is only visible if all of its antecedents are visible as well (in other words, [method is_visible_in_tree] must return true).

pub fn show(&self)

pub fn to_global(&self, local_point: Vector3) -> Vector3

Transforms local_point from this node’s local space to world space.

pub fn to_local(&self, global_point: Vector3) -> Vector3

Transforms global_point from world space to this node’s local space.

pub fn translate(&self, offset: Vector3)

Changes the node’s position by the given offset Vector3. Note that the translation offset is affected by the node’s scale, so if scaled by e.g. (10, 1, 1), a translation by an offset of (2, 0, 0) would actually add 20 (2 * 10) to the X coordinate.

pub fn translate_object_local(&self, offset: Vector3)

Changes the node’s position by the given offset Vector3 in local space.

pub fn update_gizmo(&self)

Updates the SpatialGizmo of this node.
