PolylightNode¶ Bases:
PandaNodeA PolylightNode
Inheritance diagram
-
__init__(param0: PolylightNode) → None¶
-
__init__(name: str) → None Use
PolylightNode()to construct a new PolylightNode object.
-
enable() → None¶ Enable this light
-
disable() → None¶ Disable this light
-
setPos(position: LPoint3) → None¶ Set this light’s position
-
setPos(x: float, y: float, z: float) → None Set this light’s position
-
getPos() → LPoint3¶ Returns position as a LPoint3
- Return type
LPoint3
-
setColor(color: LColor) → None¶ Set the light’s color…
-
setColor(r: float, g: float, b: float) → None Set the light’s color… 3 floats between 0 and 1
-
getColor() → LColor¶ Returns the light’s color as LColor
- Return type
LColor
-
getColorScenegraph() → LColor¶ This differs from get_color in that when applying the light color we need to make sure that a color flattening external to the PolylightNode is not ignored.
- Return type
LColor
-
setRadius(r: float) → None¶ Set radius of the spherical light volume
-
getRadius() → float¶ Get radius of the spherical light volume
-
setAttenuation(type: Attenuation_Type) → bool¶ Set ALINEAR or AQUADRATIC attenuation
-
getAttenuation() → Attenuation_Type¶ Get “linear” or “quadratic” attenuation type
- Return type
Attenuation_Type
-
setA0(a0: float) → None¶ Set the quadratic attenuation factor a0 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
setA1(a1: float) → None¶ Set the quadratic attenuation factor a1 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
setA2(a2: float) → None¶ Set the quadratic attenuation factor a2 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
getA0() → float¶ Get the quadratic attenuation factor a0 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
getA1() → float¶ Get the quadratic attenuation factor a1 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
getA2() → float¶ Get the quadratic attenuation factor a2 fd = 1 / ( a0 + a1*distance + a2*distance*distance)
-
flickerOn() → None¶ Set flickering to true so at every loop this light’s color is varied based on flicker_type
-
flickerOff() → None¶ Turn flickering off
-
isFlickering() → bool¶ Check is this light is flickering
-
setFlickerType(type: Flicker_Type) → bool¶ Flicker type can be FRANDOM or FSIN At a later point there might be a FCUSTOM Custom flicker will be a set of fix points recorded by animating the light’s intensity
-
getFlickerType() → Flicker_Type¶ Returns FRANDOM or FSIN
- Return type
Flicker_Type
-
setOffset(offset: float) → None¶ Set the offset value for the random and sin flicker variations… used to tweak the flicker This value is added to the variation
-
getOffset() → float¶ Get the offset value for the random and sin flicker variations
-
setScale(scale: float) → None¶ Set the scale value for the random and sin flicker variations… used to tweak the flicker This value is multiplied with the variation
-
getScale() → float¶ Get the scale value for the random and sin flicker variations
-
setStepSize(step: float) → None¶ Set the step size for the sin function in flicker This is the increment size for the value supplied to the sin function
-
getStepSize() → float¶ Get the step size for the sin function in flicker This is the increment size for the value supplied to the sin function
-
setFreq(f: float) → None¶ Set frequency of sin flicker
-
getFreq() → float¶ Get frequency of sin flicker
-
compareTo(other: PolylightNode) → int¶ Returns a number less than zero if this PolylightNode sorts before the other one, greater than zero if it sorts after, or zero if they are equivalent.
Two PolylightNodes are considered equivalent if they consist of exactly the same properties Otherwise, they are different; different PolylightNodes will be ranked in a consistent but undefined ordering; the ordering is useful only for placing the PolylightNodes in a sorted container like an STL set.
-
isEnabled() → bool¶ Is this light is enabled/disabled?
-
static
getClassType() → TypeHandle¶ - Return type
