As an addendum to the post I made yesterday, here is one other filter which can be used in the Starling framework that could probably come in quite handy for a few. In essence, it’s sort of a spotlight effect that illuminates a specified oval area of a Starling DisplayObject. Though I mainly see it being used for games where you only want to light up an area around your player (to move the light around, you just adjust the centerX and centerY properties), I suppose it could also produce a nice vignette effect as well. In any case you can see an example here. After the swf loads (around 200k or so), move your mouse around to see the filter in action. And if you’re looking for a flickering torch/dying flashlight or old movie effect, you can set the useFlicker property to true. In the example, clicking the image will toggle the flicker.
