A quad that efficiently draws a 2D light ray effect on its surface. That's useful for adding atmospheric effects, like the typical effects you see underwater or in a forest. (Demo Source.)
Play around with the different settings to make it suit the style you want. In addition to the class-specific properties, you can also assign an overall color or different colors per vertex.
Add it to a juggler or call advanceTime so that the effect
becomes animated.
var godRays:GodRayPlane = new GodRayPlane(320, 200); godRays.color = 0xff8000; godRays.speed = 0.1; // animation speed godRays.size = 0.1; // number of rays ~= 1 / size godRays.skew = 0; // angle of rays godRays.shear = 0; // spread of angle godRays.fade = 1; // rays fade out towards the bottom godRays.contrast = 1; // distinctiveness and brightness of the rays addChild(godRays); Starling.juggler.add(godRays);
Since most of the work is done in a shader, this effect is very lightweight and renders really fast. A MeshStyle, together with a MeshEffect, does the heavy lifting.

Questions are better asked in the forum, though.
