This is the base class for all light sources and provides settings for some basic properties, e.g. active states, strength, color values, etc.  It also provides a Transform Control with the ability to set translation, rotation, and scale keys.
−
This class is the interface to lights in the scene.
+
 
−
It provides methods to access various parts of a light such as

Description

This is the base class for all light sources and provides settings for some basic properties, e.g. active states, strength, color values, etc. It also provides a Transform Control with the ability to set translation, rotation, and scale keys.

Inheritance

RIBase > RIObject > RILight 
RILight > SpotLight | PointLight | DirectionalLight

Member Functions

SetActive ( self, bActive )

Set the active state for the light.

See Also: GetActive

Parameters

bActive [IN] The active state - bool
1 # Get light object
2 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight")
3 
4 # Set light object active status
5 light_object.SetActive(True)

GetActive ( self )

Get the active state of the light.

See Also: SetActive

Returns

Whether or not the light is active - bool
1 # Get light object
2 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight")
3 
4 # Get light object active status
5 active_status = light_object.GetActive()
6 print(active_status)

SetMultiplier ( self, kTime, fMultiplier )

Set the light's strength value at a given time.

See Also: GetMultiplier

Parameters

kTime [IN] Time at which to set the light's strength value - RTime
fMultiplier [IN] The strength value - float

Returns

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure
1 # Get light object
2 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight")
3 
4 # Set light object multiplier value
5 result = light_object.SetMultiplier(RLPy.RTime(0), 8.0)

GetMultiplier ( self )

Get the light's current strength.

See Also: SetMultiplier

Returns

The strength of the light - float
1 # Get light object
2 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight")
3 
4 # Get light object multiplier value
5 multiplier_value = light_object.GetMultiplier()
6 print(multiplier_value)

SetColor ( self, kTime, kColor )

Set the light's color at a given time.

See Also: GetColor

Parameters

kTime [IN] Time at which to set the light's color - RTime
kColor [IN] The target color for the light - RRgb

Returns

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure
1 # Get light object
2 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight")
3 
4 # Set light object color value
5 result = light_object.SetColor(RLPy.RTime(0), RLPy.RRgb.RED)

GetColor ( self )

Get the light's color at a given time.

See Also: SetColor

Returns

The light's color in RRgb - RRgb
1 # Get light object
2 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight")
3 
4 # Set light object color value
5 light_color = light_object.GetColor()
6 print(light_color)
