If you want sub-pixel movement, you must turn smoothing on for the asset, but there are a few "gotchas" that I'm aware of:
1) If DisplayObject/MovieClip has any filters applied to it (blur, drop shadow, etc.), I'm pretty sure it's impossible to get sub-pixel movement. It will only move on whole pixels which would explain that undesirable effect you described. 2) If you're animating a TextField with anti-aliasing set to "anti-alias for readability", you'll probably get some visual vibration as it moves. Obviously bitmap text (no anti-aliasing) won't work well for sub-pixel movement. 3) In certain scenarios, Flash will not allow smoothing on subloaded assets from other domains unless you have a crossdomain.xml file in place. It's a security thing. If your asset is a raster image in your library, you can simply right-click on it, choose properties, and select the "allow smoothing" checkbox. If it's a BitmapData object, you'll need to enable smoothing when you create it through code. If it's not a raster image, could try creating a BitmapData of your asset, set smoothing to true, and animate that in order to get the sub-pixel movement. Not sure it would give you great results, but it's worth a shot. Hope that helps.

AS3 Hi everyone, so I have a MC I want to move very-very slowly across the screen; so that it is subtle. I have the frame rate set to 30fps and any increase to the FPS doesn't seem to make much of a difference. I have tried basic timeline motion tween, and also the AS3 Tweener class; but in both cases I get the issue that the slow animation makes the image do little 1 pixel jumps that are VERY visible and break the effect I am going for [which needs to be extremely subtle]. Am I just stuffed? Or is there a way to achieve very smooth animations in Flash/AS3? [short of laying it all out as frames and cross fading! which would be ridiculous and over-size the file so not possible]. Maybe I just need to turn on something somewhere? I can't remember where if that's the case... Thanks!! Sebastian. _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
