sunLight property

SunLight? get sunLight

Aims directionalLight at a sky's sun so cast shadows track the sky.

While set, the binding owns directionalLight: each frame the engine points the light opposite the sky's sun and recolors it. Clearing it (setting null) removes the light the binding was driving. Pair it with a skyEnvironment on the same sky so soft IBL and the hard shadow agree.

Implementation

SunLight? get sunLight => _sunLight;

set sunLight (SunLight? value)

Implementation

set sunLight(SunLight? value) {
  // The binding owns the convenience light; when it is cleared, retire the
  // light it was driving so shadows stop.
  if (value == null &&
      _sunLight != null &&
      identical(directionalLight, _sunLight!.light)) {
    directionalLight = null;
  }
  _sunLight = value;
}
