Continuously scrolling text

[mansfieldcaleb]

I am trying to create a dynamic text field that continuously scrolls through dynamically loaded text (like a news ticker, except it scrolls down). If have got the text to load in, and I can get it to scroll with buttons, but I don't want it to use buttons. I just want it to scroll, and when it has scrolled through the text, I want it to wait for a little bit and then rescroll through it again. Do you know how I can do this with actionscript?

_root.createEmptyMovieClip("mc", 0);
_root.mc.createTextField("t", 0, 0, 0, 100, 100);
_root.mc.t.text = "BEGIN ovfpkrv werognorw ojnvwor wpjw ijege ovfpkrv werognorw ojnvwor wpjw ijege ovfpkrv werognorw ojnvwor wpjw ijege FINISHED";
_root.mc.t.wordWrap = true;
_root.mc.t.border = true;
function scrollDown() {
	trace(_root.mc.t.scroll);
	_root.mc.t.scroll = _root.mc.t.scroll%_root.mc.t.maxscroll+1;
}
setInterval(scrollDown, 1000);

thanks mate - could that great. could you just tell me how to specify the font and how to dynamically load the content with that script?

[mansfieldcaleb]

and how can i get it to pause for a few seconds when its finished scrolling through the text, before it starts scrolling again?

[mansfieldcaleb]

and is there a way to possibly make it scroll more smoother rather than line by line? sorry but i'm only a beginner.

myFormat = new TextFormat();
myFormat.font = "Verdana";
myformat.embedFonts = true;
/*i'm not sure about how to embed a font... if you can't do it, don't ask me cause i don't know more then this
but i think it's like this: go to the library, on top, on the right, there is a button. in the popUp menu
choose new font. choose the font that you want,then assign it a name. that's the name wich will appear
here: myFormat.font = "font name";

to load the text dinamically use loadVariables():
important!: the text takes some time to load, so you have to be sure that the text has loaded that's why I use onData, but I've had some trouble with it, and there is a known issue about that
in the external.txt i placed: externalText=BEGINING and more garbish

//
_root.createEmptyMovieClip("mc", 0);
_root.mc.loadVariables("external.txt");
_root.mc.onData = function() {
	trace("jong");
	_root.mc.createTextField("t", 0, 0, 0, 100, 100);
	_root.mc.t.text = _root.mc.externalText;
	_root.mc.t.wordWrap = true;
	_root.mc.t.border = true;
};
//
function scrollDown() {
	_root.mc.t.scroll = _root.mc.t.scroll%_root.mc.t.maxscroll+1;
	if (_root.mc.t.scroll == _root.mc.t.maxscroll) {
		clearInterval(firstInterval);
		secondInterval = setInterval(wait, 3000);
	}
}
firstInterval = setInterval(scrollDown, 1000);
function wait() {
	clearInterval(secondInterval);
	firstInterval = setInterval(scrollDown, 1000);
}

you are a genius mate. just one more thing - do you know how i can make this a html text field, and can i make the scroll run more smoothly rather than line by line? so it just looks like a motion tween sort of thing?

[nunomira]

for the html thing:
instead of

_root.mc.createTextField("t", 0, 0, 0, 100, 100);
_root.mc.t.text = _root.mc.externalText;
_root.mc.t.wordWrap = true;

use this

_root.mc.createTextField("t", 0, 0, 0, 100, 100);
_root.mc.t.htmlText = true;
_root.mc.t.htmlText = _root.mc.externalText;
_root.mc.t.wordWrap = true;

it is not possible to make it smoother because, to make it scroll i use textField.scroll, and it receives integers only
