Description

This class provides spotlight related operations, i.e. whether or not to cast shadows, light color, light ray direction, light strength, etc.

Inheritance

RIBase > RIObject > RILight > RISpotLight

Examples

 1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
 2 
 3 # set Parent
 4 prop2 = RLPy.RScene.FindObject(RLPy.EObjectType_Prop, "Box2")
 5 result = light_object.SetParent(prop2)
 6 result = light_object.SetParent(None) #detach from parent
 7 
 8 # link to &  unlink
 9 result = light_object.LinkTo(prop2, RLPy.RTime(0))
10 result = light_object.UnLink(RLPy.RTime(0))
11 # set name
12 light_object.SetName( "new_name" )
13 #get bound
14 ret_max = RLPy.RVector3()
15 ret_center = RLPy.RVector3()
16 ret_min = RLPy.RVector3()
17 ret = light_object.GetBounds( ret_max, ret_center, ret_min )
18 print(ret)
19 #get pivot
20 ret_pos = RLPy.RVector3()
21 ret_rot = RLPy.RVector3()
22 light_object.GetPivot( ret_pos, ret_rot )
23 print(ret)
24 #clone object
25 clone_light_object = light_object.Clone()
26 print( clone_light_object )
27 #is selected
28 RLPy.RScene.SelectObject(light_object)
29 print(light_object.IsSelected()) #True

Member Functions

GetDarkenShadowStrength ( self )

Get the Spotlight's shadow strength at a given point in time (0 to 100).

See Also: SetDarkenShadowStrength

Returns

Spotlight's shadow strength - float
1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
2  
3 #get light shadow strength
4 print(light_object.GetDarkenShadowStrength())

GetRange ( self )

Get the Spotlight's range distance.

See Also: SetRange

Returns

Spotlight's range attribute - float
1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
2  
3 #get light range
4 print(light_object.GetRange())

GetSpotLightBeam ( self, nAngle, nFalloff )

Get the Spotlight's light beam attributes, e.g. beam angle and spill light attenuation (falloff intensity).

See Also: SetSpotLightBeam

Parameters

nAngle [OUT] Spotlight's angle value - int
nFalloff [OUT] Spotlight's falloff value - int

Returns

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure
 1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
 2  
 3 # set light beam
 4 spot_light_falloff_power = 40.0
 5 spot_light_angle = 135.0
 6 light_object.SetSpotLightBeam(RLPy.RTime(0), spot_light_falloff_power, spot_light_angle)
 7 # get light beam
 8 angle = 0
 9 falloff = 0
10 light_object.GetSpotLightBeam(angle, falloff)
11 print(angle) # angle = 135
12 print(falloff) # falloff = 40

IsCastShadow ( self )

Check whether or not the Spotlight is casting shadows.

See Also: SetCastShadow

Returns

True if the spotlight is casting shadows, else False - bool
1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
2  
3 print(light_object.IsCastShadow())

SetCastShadow ( self, bEnable )

Turn on / off the Spotlight's cast shadows.

See Also: IsCastShadow

Parameters

bEnable [IN] Whether to cast shadows - bool

Returns

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure
1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
2 light_object.SetCastShadow(True)
3 print(light_object.IsCastShadow())

SetDarkenShadowStrength ( self, kTime, fStrength )

Set the Spotlight's shadow strength at a given point in time (0 to 100).

See Also: GetDarkenShadowStrength

Parameters

fStrength [IN] Spotlight shadow strength value - float

Returns

Success - RLPy.RStatus.Success
Failure - RLPy.RStatus.Failure
1 light_object = RLPy.RScene.FindObject(RLPy.EObjectType_Light, "Spotlight") # Find the spotlight by name
2  
3 # Set light shadow strength
4 light_object.SetDarkenShadowStrength(RLPy.RTime(0), 50.0)

SetRange ( self, kTime, fRange )

Set the Spotlight's range value at a given point in time.

See Also: GetRange

Parameters

kTime [IN] Time at which to set the beam - RTime
fRange [IN] Spotlight range value - float
