class PolylightNode¶

Bases: PandaNode

A PolylightNode

Inheritance diagram

enum Attenuation_Type¶

enumerator ALINEAR = 0¶

enumerator AQUADRATIC = 1¶

enum Flicker_Type¶

enumerator FRANDOM = 0¶

enumerator FSIN = 1¶

enumerator FCUSTOM = 2¶

__init__(param0: PolylightNode) → None¶

__init__(name: str) → None¶: Use PolylightNode() to construct a new PolylightNode object.

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.

disable() → None¶: Disable this light

enable() → None¶: Enable this light

flickerOff() → None¶: Turn flickering off

flickerOn() → None¶: Set flickering to true so at every loop this light’s color is varied based on flicker_type

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)

getAttenuation() → Attenuation_Type¶

Get “linear” or “quadratic” attenuation type

Return type: Attenuation_Type

static getClassType() → TypeHandle¶

Return type: TypeHandle

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

getFlickerType() → Flicker_Type¶

Returns FRANDOM or FSIN

Return type: Flicker_Type

getFreq() → float¶: Get frequency of sin flicker

getOffset() → float¶: Get the offset value for the random and sin flicker variations

getPos() → LPoint3¶

Returns position as a LPoint3

Return type: LPoint3

getRadius() → float¶: Get radius of the spherical light volume

getScale() → float¶: Get the scale value for the random and sin flicker variations

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

isEnabled() → bool¶: Is this light is enabled/disabled?

isFlickering() → bool¶: Check is this light is flickering

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)

setAttenuation(type: Attenuation_Type) → bool¶: Set ALINEAR or AQUADRATIC attenuation

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

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

setFreq(f: float) → None¶: Set frequency of sin flicker

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

setPos(position: LPoint3) → None¶: Set this light’s position

setPos(x: float, y: float, z: float) → None¶: Set this light’s position

setRadius(r: float) → None¶: Set radius of the spherical light volume

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

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
