Public Property LinearAttenuation As Single
Property Value
float
The linear coefficient in the light's attenuation equation that determines how the light falls-off with distance. Range is from 0 to infinity.
Examples
_pointLight.LinearAttenuation = .14F;
Remarks
The PointLight.LinearAttenuation property is part of the attenuation equation which also contains PointLight.ConstantAttenuation and PointLight.QuadraticAttenuation:
![1/(Constant+Linear*(Distance/100)+Quadratic*(Distance/100)*(Distance/100))](windows.ui.composition/images/attenuationequation.png?view=winrt-22621)
