Unigine.WidgetSprite Class
| Inherits from: | Widget |
This base class is used to create sprites, which are basically any widgets dealing with images.
A sprite has a background layer which is used to calculate a bounding box of the widget and in addition can have a number of layers. All layer including the bottom one can be assigned textures, tiled and blended.
Notice
You can transform all layers, but avoid rotating a background layer. Being used to calculate a BB, it stretches if rotated. Rotate layers instead.
