enum Operation |
const RenderAttrib addLight | ( | Light | light | ) |
Returns a new LightAttrib, just like this one, but with the indicated light added to the list of lights.
This method is now deprecated. Use add_on_light() or add_off_light() instead.
const RenderAttrib addOffLight | ( | const NodePath | light | ) |
Returns a new LightAttrib, just like this one, but with the indicated light added to the list of lights turned off by this attrib.
const RenderAttrib addOnLight | ( | const NodePath | light | ) |
Returns a new LightAttrib, just like this one, but with the indicated light added to the list of lights turned on by this attrib.
LColor getAmbientContribution | ( | ) |
Returns the total contribution of all the ambient lights.

static |
Light getLight | ( | int | n | ) |
Returns the nth light listed in the attribute.
This method is now deprecated. LightAttribs nowadays have a separate list of on_lights and off_lights, so this method doesn't make sense. Query the lists independently.
NodePath getMostImportantLight | ( | ) |
Returns the most important light (that is, the light with the highest priority) in the LightAttrib, excluding any ambient lights.
Returns an empty NodePath if no non-ambient lights are found.
int getNumLights | ( | ) |
Returns the number of lights listed in the attribute.
This method is now deprecated. LightAttribs nowadays have a separate list of on_lights and off_lights, so this method doesn't make sense. Query the lists independently.
int getNumNonAmbientLights | ( | ) |
Returns the number of non-ambient lights that are turned on by this attribute.
int getNumOffLights | ( | ) |
Returns the number of lights that are turned off by the attribute.
int getNumOnLights | ( | ) |
Returns the number of lights that are turned on by the attribute.
NodePath getOffLight | ( | int | n | ) |
Returns the nth light turned off by the attribute, sorted in arbitrary (pointer) order.
list getOffLights | ( | ) |
NodePath getOnLight | ( | int | n | ) |
Returns the nth light turned on by the attribute, sorted in render order.
list getOnLights | ( | ) |
LightAttrib::Operation getOperation | ( | ) |
Returns the basic operation type of the LightAttrib.
If this is O_set, the lights listed here completely replace any lights that were already on. If this is O_add, the lights here are added to the set of lights that were already on, and if O_remove, the lights here are removed from the set of lights that were on.
This method is now deprecated. LightAttribs nowadays have a separate list of on_lights and off_lights, so this method doesn't make sense. Query the lists independently.
bool hasAllOff | ( | ) |
Returns true if this attrib turns off all lights (although it may also turn some on).
bool hasAnyOnLight | ( | ) |
Returns true if any light is turned on by the attrib, false otherwise.
bool hasLight | ( | Light | light | ) |
Returns true if the indicated light is listed in the attrib, false otherwise.
This method is now deprecated. LightAttribs nowadays have a separate list of on_lights and off_lights, so this method doesn't make sense. Query the lists independently.

bool hasOnLight | ( | const NodePath | light | ) |
