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, nAttenuation )
Get the Spotlight's light beam attributes, e.g. beam angle and spill light attenuation (falloff intensity).
- ⚠ Current implementation is faulty, subject to change in later editions.
See Also: SetSpotLightBeam
Parameters
- nAngle [OUT] Spotlight's angle value - int
- nFalloff [OUT] Spotlight's falloff value - int
- nAttenuation [OUT] Spotlight's attenuation 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 light_object.SetSpotLightBeam(RLPy.RTime(0), 90, 50, 2)
5
6 # Get light beam
7 angle = 0
8 falloff = 0
9 attenuation = 0
10 status, angle, falloff, attenuation = light_object.GetSpotLightBeam(angle, falloff, attenuation)
11
12 print(status.IsError()) # False
13 print(angle) # 90
14 print(falloff) # 50
15 print(attenuation) # 2
IsCastShadow ( self )
Check whether or not the Spotlight is casting shadows.
See Also: SetCastShadow
