* @class Phaser.Sprite
*
* @classdesc Create a new `Sprite` object. Sprites are the lifeblood of your game, used for nearly everything visual.
*
2013-10-25 15:54:40 +00:00
* At its most basic a Sprite consists of a set of coordinates and a texture that is rendered to the canvas.
* They also contain additional properties allowing for physics motion (via Sprite.body), input handling (via Sprite.input),
* events (via Sprite.events), animation (via Sprite.animations), camera culling and more. Please see the Examples for use cases.
