The directional light emits light in one direction from an unidentifiable source located infinitely far away. This is similar to the way sunlight works in real life. A directional light has infinite range and does not diminish.
若 castsShadow is enabled, shadows will be parallel to the light direction.
Moving a directional light does not have any effect. The light will always be emitted in the direction of the light's Z axis.
Rotating the light along its X or Y axis will change the direction of the light emission.
Scaling a directional light will only have an effect in the following cases:
If the scale of any axis is set to 0, the light will be emitted along the world's Z axis.
注意： Rotating the light will then have no effect.
