Smooth Image Scroll in Flash

[orlNewbie]

what's up forum...


many flash ads these days, incorporate an image...scrollling across the window....i'm trying to get this effect (which is quite simple), but it's not turning out very smooth...i have a frame rate of about 35 and have spanned the movement over about 250 frames, i'd rather not use this many frames...but i want the image to move across very slowly...but very smooth...right now..all i could get is a very jerky motion...hope my explanation was clear...

any ideas?

35 is a high frame rate for web based applications however you will get a much smoother effect using actionsript to control the movement of the image rather than all those frames. just build a loop that incrementally alters the _x and _y properties of the image

Hi there

There shouldn't be a problem. How big is your image? Is this movie embeded in another one? If so you may set the frame rate high for the scroll but it will take on the frame rate of the parent movie. Otherwise , without more information, I can't see why there would be any problem.

Bill, thanks so much for your qucik response and advice..
however, i'm still quite unfamiliar to action scripting...
do you think you could provide me some example to assist in achieving my objective...how to create the script..what the parameters might be etc...?

thanks again very much for the assist

oldgrey, no it's not embedded in any other movies...i just used a high frame rate, as i imagined the scroll would be a lot smoother than if it were lower...however it's still turning out somewhat jerky...the images are about 450x300...

i havent had a chance to try this out but something like

clip._x=0;
clip._y=0;
for(i=0;i<640;i++){
//keeping y constant
clip._x=i;
//delay suggest using gettimer()if needed
}

play around with the values and you ought to get a smooth scroll. it may be necessary to introduce a delay as code as written above will flash the clip across the screen. you could also try increasing the number of loops and reducing the value of i.
