setIntensity

actual fun setIntensity(instance: EntityInstance, intensity: Float)

Dynamically update the light's intensity. Meaning depends on light type:

Directional: illuminance in lux
Point/Spot: luminous power in lumen Intensity can be negative.

Parameters

instance

Light instance

intensity

New intensity

actual fun setIntensity(instance: EntityInstance, watts: Float, efficiency: Float)

Dynamically update the light's intensity from watts and efficiency. Equivalent to setIntensity(watts * 683.0 * efficiency).

Parameters
