<description>
A Spotlight is a type of [Light3D] node that emits lights in a specific direction, in the shape of a cone. The light is attenuated through the distance. This attenuation can be configured by changing the energy, radius and attenuation parameters of [Light3D].
[b]Note:[/b] When using the Mobile rendering method, only 8 spot lights can be displayed on each mesh resource. Attempting to display more than 8 spot lights on a single mesh resource will result in spot lights flickering in and out as the camera moves. When using the Compatibility rendering method, only 8 spot lights can be displayed on each mesh resource by default, but this can be increased by adjusting [member ProjectSettings.rendering/limits/opengl/max_lights_per_object].
[b]Note:[/b] When using the Mobile or Compatibility rendering methods, spot lights will only correctly affect meshes whose visibility AABB intersects with the light's AABB. If using a shader to deform the mesh in a way that makes it go outside its AABB, [member GeometryInstance3D.extra_cull_margin] must be increased on the mesh. Otherwise, the light may not be visible on the mesh.

The spotlight's angle in degrees.
[b]Note:[/b] [member spot_angle] is not affected by [member Node3D.scale] (the light's scale or its parent's scale).

<member name="spot_angle_attenuation" type="float" setter="set_param" getter="get_param" default="1.0">
The spotlight's angular attenuation curve.

The spotlight's light energy attenuation curve.
</member>
<member name="spot_range" type="float" setter="set_param" getter="get_param" default="5.0">
The maximal range that can be reached by the spotlight. Note that the effectively lit area may appear to be smaller depending on the [member spot_attenuation] in use. No matter the [member spot_attenuation] in use, the light will never reach anything outside this range.
[b]Note:[/b] [member spot_range] is not affected by [member Node3D.scale] (the light's scale or its parent's scale).
