Edit

The linear coefficient in the light's attenuation equation that determines how the light falls off with distance. Animatable.

public:
 property float LinearAttenuation { float get(); void set(float value); };

float LinearAttenuation();

void LinearAttenuation(float value);

public float LinearAttenuation { get; set; }

var single = spotLight.linearAttenuation;

Public Property LinearAttenuation As Single

Property Value

Single

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

_spotLight.LinearAttenuation = .14F;

Remarks

The SpotLight.LinearAttenuation property is part of the attenuation equation which also contains SpotLight.ConstantAttenuation and SpotLight.QuadraticAttenuation:

1/(Constant+Linear*(Distance/100)+Quadratic*(Distance/100)*(Distance/100))
