DirectionalLight2D

继承： Light2D < Node2D < CanvasItem < Node < Object

Directional 2D light from a distance.

描述

A directional light is a type of Light2D node that models an infinite number of parallel rays covering the entire scene. It is used for lights with strong intensity that are located far away from the scene (for example: to model sunlight or moonlight).

Note: DirectionalLight2D does not support light cull masks (but it supports shadow cull masks). It will always light up 2D nodes, regardless of the 2D node's CanvasItem.light_mask.

属性说明

float height = 0.0

  • void set_height ( value: float )
  • float get_height ( )

The height of the light. Used with 2D normal mapping. Ranges from 0 (parallel to the plane) to 1 (perpendicular to the plane).

float max_distance = 10000.0

  • void set_max_distance ( value: float )
  • float get_max_distance ( )

The maximum distance from the camera center objects can be before their shadows are culled (in pixels). Decreasing this value can prevent objects located outside the camera from casting shadows (while also improving performance). Camera2D.zoom is not taken into account by max_distance, which means that at higher zoom values, shadows will appear to fade out sooner when zooming onto a given point.
