Instance Property


The radial angle, in degrees, of the area fully illuminated by the light.


var innerConeAngle: Float { get set }


This property measures the angle from the light axis (the direction in which the light points; the negative z-axis of its local coordinate space) to the edge of the light’s effect. For example, a cone angle of 22.5 degrees (the default) creates a broad spot light. (The light’s lightType value is An angle of 90 degrees divides space evenly, illuminating in all directions in front of the light and none behind, and an angle of 180 degrees illuminates in all directions (creating a light whose type is MDLLightType.point).
