Class Sprite

  • Direct Known Subclasses:
    TextureAtlas.AtlasSprite
    public class Sprite
extends TextureRegion
    Holds the geometry, color, and texture information for drawing 2D sprites using Batch. A Sprite has a position and a size given as width and height. The position is relative to the origin of the coordinate system specified via Batch.begin() and the respective matrices. A Sprite is always rectangular and its position (x, y) are located in the bottom left corner of that rectangle. A Sprite also has an origin around which rotations and scaling are performed (that is, the origin is not modified by rotation and scaling). The origin is given relative to the bottom left corner of the Sprite, its position.
