I’ve a trivial (not for me) question!  
I try to move a movieclip via actionscript in the following way:

here is the “stupid” code in the main frame

\_root.onEnterFrame=function()  
{  
ball.\_x-=5;  
if (ball.\_x\<0) ball.\_x=500;  
}

where “ball” is the instance name of the movieclip

The problem is that the ball **flickers too much** during the animation, even if the frame rate is the highest and even if the movieclip is the simplest one (in this case a small ball)!

How can I reduce this horrible effect?

Thanks!  
S.

I just tried the “MC TWEEN” class, the motion is very smooth but the movieclip still flickers.  
My laptop is powerfull so it cannot be a ram or cpu problem…  
What to do?

Thanks a lot,  
Simone

you probably have more than one frame in your ball clip, which is causing it to flicker

ie, frame 1, ball

frame 2, nothing

played quickly it makes it flicker

either stick in a stop() command or get rid of the extra frame

No, my movielcip has a single frame, and also the stage has a single looping frame.  
It seems that flash is too slow to refresh the screen, as it always happens (for example using openGL) in a “non double buffer” animation.  
I’m getting crazy!!! This flickering occurs also in all the examples I downloaded.  
Help!!!

I tried to use updateAfterEvent() , but it seems to apply only on some event as explained in the help :  
"This function works only with certain Mouse and MovieClip handlers: the mouseDown, mouseUp, mouseMove, keyDown and keyUp handlers for the Mouse class; the onMouseMove, onMouseDown, onMouseUp, onKeyDown, and onKeyUp handlers for the MovieClip class. It does not work with the Key class. "

your just the most insane noob… I might just like you

> import mx.transitions.Tween;  
> import mx.transitions.easing.\*;

var tw1:Tween = new Tween(ball, “\_x”, Strong.easeIn, 100, 0, 5, true);

try the default tween class in flash

try putting in stop() in , I assumed you had

I don’t know that tween class… but no major problems my end, although onload part of the tween command seemed off to me

Ok last question!

look at this site  
[http://www.oman3d.com/tutorials/flash/tweenclasseasing/](http://www.oman3d.com/tutorials/flash/tweenclasseasing/)

In the middle of the page there is an example of the tween for 2 balls!

The motion is smooth but there is the “famous flickering” !

Can you tell me if you see it?!

thank for the attention!
