Overview

Light3D is the abstract base class for light nodes. As it can't be instantiated, it shouldn't be used directly. Other types of light nodes inherit from it. Light3D contains the common variables and parameters used for lighting.

Types

type Advanced 

type Advanced = class

Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.

type Any 

type Any interface {
	gd.IsClass
	AsLight3D() Instance
}

type BakeMode 

type BakeMode int //gd:Light3D.BakeMode

const (
	// Light is ignored when baking. This is the fastest mode, but the light will not be taken into account when baking global illumination. This mode should generally be used for dynamic lights that change quickly, as the effect of global illumination is less noticeable on those lights.
	//
	// Note: Hiding a light does not affect baking [LightmapGI]. Hiding a light will still affect baking [VoxelGI] and SDFGI (see [Environment.SdfgiEnabled]).
	//
	// [Environment.SdfgiEnabled]: https://pkg.go.dev/graphics.gd/classdb/Environment#Instance.SdfgiEnabled
	// [LightmapGI]: https://pkg.go.dev/graphics.gd/classdb/LightmapGI
	// [VoxelGI]: https://pkg.go.dev/graphics.gd/classdb/VoxelGI
	BakeDisabled BakeMode = 0
	// Light is taken into account in static baking ([VoxelGI], [LightmapGI], SDFGI ([Environment.SdfgiEnabled])). The light can be moved around or modified, but its global illumination will not update in real-time. This is suitable for subtle changes (such as flickering torches), but generally not large changes such as toggling a light on and off.
	//
	// Note: The light is not baked in [LightmapGI] if [EditorOnly] is true.
	//
	// [EditorOnly]: https://pkg.go.dev/graphics.gd/classdb/#Instance.EditorOnly
	// [Environment.SdfgiEnabled]: https://pkg.go.dev/graphics.gd/classdb/Environment#Instance.SdfgiEnabled
	// [LightmapGI]: https://pkg.go.dev/graphics.gd/classdb/LightmapGI
	// [VoxelGI]: https://pkg.go.dev/graphics.gd/classdb/VoxelGI
	BakeStatic BakeMode = 1
	// Light is taken into account in dynamic baking ([VoxelGI] and SDFGI ([Environment.SdfgiEnabled]) only). The light can be moved around or modified with global illumination updating in real-time. The light's global illumination appearance will be slightly different compared to [BakeStatic]. This has a greater performance cost compared to [BakeStatic]. When using SDFGI, the update speed of dynamic lights is affected by [ProjectSettings] "rendering/global_illumination/sdfgi/frames_to_update_lights".
