## Detailed Description

Scene node which is a dynamic light.

You can switch the light on and off by making it visible or not. It can be animated by ordinary scene node animators. If the light type is directional or spot, the direction of the light source is defined by the rotation of the scene node (assuming (0,0,1) as the local direction of the light).

## Member Function Documentation

virtual void irr::scene::ILightSceneNode::enableCastShadow | ( | bool | shadow = `true` | ) | `[pure virtual]`

Sets whether this light casts shadows.

Enabling this flag won't automatically cast shadows, the meshes will still need shadow scene nodes attached. But one can enable or disable distinct lights for shadow casting for performance reasons.

Parameters:

  | shadow | True if this light shall cast shadows.

virtual bool irr::scene::ILightSceneNode::getCastShadow | ( |  | ) | const`[pure virtual]`

Check whether this light casts shadows.

Returns:
  True if light would cast shadows, else false.

virtual video::SLight& irr::scene::ILightSceneNode::getLightData | ( |  | ) | `[pure virtual]`

Gets the light data associated with this ILightSceneNode.

Returns:
  The light data.

virtual const video::SLight& irr::scene::ILightSceneNode::getLightData | ( |  | ) | const`[pure virtual]`

Gets the light data associated with this ILightSceneNode.

Returns:
  The light data.

Referenced by ILightSceneNode().

virtual video::E_LIGHT_TYPE irr::scene::ILightSceneNode::getLightType | ( |  | ) | const`[pure virtual]`

Gets the light type.

Returns:
  The current light type.

virtual f32 irr::scene::ILightSceneNode::getRadius | ( |  | ) | const`[pure virtual]`

Gets the light's radius of influence.

Returns:
  The current radius.

virtual void irr::scene::ILightSceneNode::setLightData | ( | const video::SLight & | light | ) | `[pure virtual]`

Sets the light data associated with this ILightSceneNode.

Parameters:

  | light | The new light data.

Referenced by ILightSceneNode().

virtual void irr::scene::ILightSceneNode::setLightType | ( | video::E_LIGHT_TYPE | type | ) | `[pure virtual]`

Sets the light type.

Parameters:

  | type | The new type.

Referenced by ILightSceneNode().

virtual void irr::scene::ILightSceneNode::setRadius | ( | f32 | radius | ) | `[pure virtual]`

Sets the light's radius of influence.

Outside this radius the light won't lighten geometry and cast no shadows. Setting the radius will also influence the attenuation, setting it to (0,1/radius,0). If you want to override this behavior, set the attenuation after the radius.

Parameters:

  | radius | The new radius.

Referenced by ILightSceneNode().

virtual void irr::scene::ILightSceneNode::setVisible | ( | bool | isVisible | ) | `[pure virtual]`

Sets if the node should be visible or not.

All children of this node won't be visible either, when set to true.

Parameters:

  | isVisible | If the node shall be visible.

Reimplemented from irr::scene::ISceneNode.
