[−][src]Struct gdnative_bindings::SpotLight
core class SpotLight
inherits Light
(unsafe).
Official documentation
See the documentation of this class in the Godot engine's official documentation.
Memory management
Non reference counted objects such as the ones of this type are usually owned by the engine.
SpotLight
is a reference-only type. Persistent references can
only exist in the unsafe Ref<SpotLight>
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
SpotLight inherits methods from:
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 SpotLight
[src]
pub fn new() -> Ref<Self, Unique>
[src]
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 bake_mode(&self) -> BakeMode
[src]
The light's bake mode. See [enum BakeMode].
pub fn color(&self) -> Color
[src]
The light's color. An [i]overbright[/i] color can be used to achieve a result equivalent to increasing the light's [member light_energy].
pub fn cull_mask(&self) -> i64
[src]
The light will affect objects in the selected layers.
pub fn param(&self, param: i64) -> f64
[src]
Attempts to reduce [member shadow_bias] gap.
pub fn shadow_color(&self) -> Color
[src]
The color of shadows cast by this light.
pub fn shadow_reverse_cull_face(&self) -> bool
[src]
If [code]true[/code], reverses the backface culling of the mesh. This can be useful when you have a flat mesh that has a light behind it. If you need to cast a shadow on both sides of the mesh, set the mesh to use double-sided shadows with [constant GeometryInstance.SHADOW_CASTING_SETTING_DOUBLE_SIDED].
pub fn has_shadow(&self) -> bool
[src]
If [code]true[/code], the light will cast shadows.
pub fn is_editor_only(&self) -> bool
[src]
If [code]true[/code], the light only appears in the editor and will not be visible at runtime.
pub fn is_negative(&self) -> bool
[src]
If [code]true[/code], the light's effect is reversed, darkening areas and casting bright shadows.
pub fn set_bake_mode(&self, bake_mode: i64)
[src]
The light's bake mode. See [enum BakeMode].
pub fn set_color(&self, color: Color)
[src]
The light's color. An [i]overbright[/i] color can be used to achieve a result equivalent to increasing the light's [member light_energy].
pub fn set_cull_mask(&self, cull_mask: i64)
[src]
The light will affect objects in the selected layers.
pub fn set_editor_only(&self, editor_only: bool)
[src]
If [code]true[/code], the light only appears in the editor and will not be visible at runtime.
pub fn set_negative(&self, enabled: bool)
[src]
If [code]true[/code], the light's effect is reversed, darkening areas and casting bright shadows.
pub fn set_param(&self, param: i64, value: f64)
[src]
Attempts to reduce [member shadow_bias] gap.
pub fn set_shadow(&self, enabled: bool)
[src]
If [code]true[/code], the light will cast shadows.
pub fn set_shadow_color(&self, shadow_color: Color)
[src]
The color of shadows cast by this light.
pub fn set_shadow_reverse_cull_face(&self, enable: bool)
[src]
If [code]true[/code], reverses the backface culling of the mesh. This can be useful when you have a flat mesh that has a light behind it. If you need to cast a shadow on both sides of the mesh, set the mesh to use double-sided shadows with [constant GeometryInstance.SHADOW_CASTING_SETTING_DOUBLE_SIDED].
