Examples of com.badlogic.gdx.graphics.g2d.TextureRegion

com.badlogic.gdx.graphics.g2d.TextureRegion
Defines a rectangular area of a texture. The coordinate system used has its origin in the upper left corner with the x-axis pointing to the right and the y axis pointing downwards. @author mzechner @author Nathan Sweet
