Overview ¶
Casts light in a 2D environment. A light is defined as a color, an energy value, a mode (see constants), and various other parameters (range and shadows-related).

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 BlendMode ¶
type BlendMode int //gd:Light2D.BlendMode
const ( // Adds the value of pixels corresponding to the Light2D to the values of pixels under it. This is the common behavior of a light. BlendModeAdd BlendMode = 0 // Subtracts the value of pixels corresponding to the Light2D to the values of pixels under it, resulting in inversed light effect. BlendModeSub BlendMode = 1 // Mix the value of pixels corresponding to the Light2D to the values of pixels under it by linear interpolation. BlendModeMix BlendMode = 2 )
type Extension ¶
Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension
func (*Extension[T]) AsCanvasItem ¶
func (self *Extension[T]) AsCanvasItem() CanvasItem.Instance
type ID ¶
ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.
type Instance ¶
Instance of the class with convieniently typed arguments and results.
var Nil Instance
Nil is a nil/null instance of the class. Equivalent to the zero value.
func (Instance) AsCanvasItem ¶
func (self Instance) AsCanvasItem() CanvasItem.Instance
func (Instance) EditorOnly ¶
func (Instance) GetHeight ¶
Returns the light's height, which is used in 2D normal mapping. See graphics.gd/classdb/PointLight2D.Instance.Height and graphics.gd/classdb/DirectionalLight2D.Instance.Height.
func (Instance) RangeItemCullMask ¶
func (Instance) RangeLayerMax ¶
func (Instance) RangeLayerMin ¶
func (Instance) SetBlendMode ¶
func (Instance) SetEditorOnly ¶
func (Instance) SetEnabled ¶
func (Instance) SetHeight ¶
Sets the light's height, which is used in 2D normal mapping. See graphics.gd/classdb/PointLight2D.Instance.Height and graphics.gd/classdb/DirectionalLight2D.Instance.Height.

type ShadowFilter ¶
type ShadowFilter int //gd:Light2D.ShadowFilter
const ( // No filter applies to the shadow map. This provides hard shadow edges and is the fastest to render. See [Instance.ShadowFilter]. ShadowFilterNone ShadowFilter = 0 // Percentage closer filtering (5 samples) applies to the shadow map. This is slower compared to hard shadow rendering. See [Instance.ShadowFilter]. ShadowFilterPcf5 ShadowFilter = 1 // Percentage closer filtering (13 samples) applies to the shadow map. This is the slowest shadow filtering mode, and should be used sparingly. See [Instance.ShadowFilter]. ShadowFilterPcf13 ShadowFilter = 2 )
