One of the things that really appealed to me about ND2D over the Starling Framework was the ability to scroll textures by manipulating their UV coordinates like this. Obviously this could come in pretty darned handy for space games, side scrollers, etc, etc. Well, as it turns out, doing the same thing is also pretty easy in Starling using the Image object’s setTexCoords() method. Generally speaking, you loop through the four vertex points of the Image in question, get the coordinates of each vertex using getTexCoords() (which returns a Point instance), add a very small amount to the x and y properties of that point, then reset the coordinates of that vertex with setTexCoords() (which takes the vertex id and a Point). Stealing assets like some mad pirate (the star fields from the ND2D example above and the ship from Lee Brimelow’s space game), I came up from this quick example here (around 430k with no preloader). And the full source for the Starling bit (the magic taking place in updateStarfields() )… [crayon-6046c77db5d32338493207/]
