moving object across screen smoothly in as3

Question

I'm programming a game in as3 using flashDevelop the player (among other things) is moving across the screen using EnterFrame event which update his coordinates while he moves its hard to see details of the animation and its look kinda blur how do i fix this problem?

Another thing that might be useful depending on the type of movement and animations you want is Tweens. Just google "Flash as3 Tweens" or check out a simple tutorial like [this](http://www.zedia.net/actionscript-3-tweens-tutorial/) — M. Laing, Feb 16 '12 at 01:05
What is the object that you are animating? A vector or bitmap? — redhotvengeance, Feb 17 '12 at 23:45

As Patrick mentioned you should avoid non integer co-ordinates. You just need to round the values. So instead of:

clip.x += value

Use:

clip.x += Math.round(value)

If you set non-integer co-ordinates Flash the clip may appear blurry due to anti-aliasing as Flash is trying to split pixels. You could also try increasing the frame rate.

Have you considered using Tweening libraries?

Some of them are lightweight and automatically make calculations on the movement according to the FPS ( which you should try to maintain high )

Here are couple of them:

Hope it helps

addEventListener(Event.ENTER_FRAME, smothMove);

var i:int = 0;
var j:int= 1;

function smothMove (event:Event):void
{

clip.x = clip.x + i;
        i = i + j;

}
