Hi

I need to create a sideways scroll effect, ideally using only actionscript, but to keep it simple I essentially need to be able to click and hold down a button and have another MC move, a progressive movement as opposed to an abrupt change from point A to B. I can’t use motion tweening animation between frames it has to be done with code…

Can this be done?

Thanks

Not unless you make loads of little “ **abrupt changes** ” till it gets where you want it!

do you have a fla? What you can do it set up a button to create an onEnterFrame handler for your movie clip that will move it a few pixels at a time. This will end up looking like motion. Then, you set it up to delete the onEnterFrame handler when they let go of the button, stopping the motion. I posted something like this a couple days ago let me see if i can find it.

what i meant was that you can move something onEnterFrame little by little until it gets where u want it to be!!!

this.onEnterFrame = function(){  
if( myClip.\_x+5 \< myLimit){  
myClip.\_x +=5;  
}  
}

There are much better ways of doing it (easing with physics, etc)  
but this is the basic thing you need

Cool that is very near to the effect i wish to achieve, 1 last thing

Is it possible to have it so that it only scrolls when the user holds the button down? as opposed to a rollover…

flash MX only has a press event :-/

oh yeah.  
[AS]  
on (press){  
this.onEnterFrame = function(){  
if(targetMovie.\_x \< moviesXLimit) targetMovie.\_x+=5;  
}  
}  
on (release){  
delete this.onEnterFrame;  
}  
[/AS]

should do it. you can use the on press event coupled with onEnterFrame to make a scrollbar type effect.

Thanks grandsp5 that worked perfectly, I have never come across anything like  
[AS]this.onEnterFrame = function(){  
if(targetMovie.\_x \< moviesXLimit) targetMovie.\_x+=5;  
}  
[/AS]

Is this new to FlashMX, do you know where i can learn more?

Thanks again :thumb:

The onEnterFrame handler is I believe a new thing. (I only started flash about a 2 and a half months ago so I’m not totally sure, I really only have experience with MX) Do some searching on the forums, I had a thread i posted about the onEnterFrame handler a while back. It basically runs a check at the framerate of the movie and executes the code. IE - that code would be executed 12 times a second if your fps is 12.

glad it worked for you 🙂
