Basic Scrolling AS Question

[wyclef]

Hi, i've got a text field "scrollable_text" and two buttons with the following code on them to "scroll" the text. Just wondering if there is a way to stop it when it reaches the end of the text (top and bottom). currently u can scroll up or down as long as u want.....



on( press, release, keyPress "")
{
scrollable_text._y -= 30;
}




on( press, release, keyPress "")
{
scrollable_text._y += 30;
}

Are you loading in dynamic text that changes a lot? Or is it a set amount of text?

:hr:

it will not be dynamically loaded in but it will change a lot, however...if there was an easy way to designate top and bottom i might eb able to just set the max and min pts and not worry too much. as long as it doesnt go on forever...

You can use the textWidth and textHeight properties of a textfield to set those mins and maxs and tell the scroller not to go beyond say textHeight +5 or something.

can u give me an example of what the AS would look like?

Find the attachment in this thread (post #5): auto resize a caption (http://www.kirupa.com/forum/showthread.php?t=55969)

This doesn't use a scroller but captures the text field width and height and adjusts them for the amout of text loaded in. It's really just a resizing rollover caption for buttons but you get the idea.

Hope it helps!

I added this to my buttons now and nothing scrolls anymore...what's wrong with the code?



on (press, release, keyPress "<Up>") {
if (scrolling && scroll_txt._y<0) {
scroll_txt._y += 10;
}
}




on (press, release, keyPress "<Down>") {
if (scrolling && scroll_txt._y>-(scroll_txt._height-50)) {
scroll_txt._y -= 10;
}
}
