Digital Workshop

Been trying for ages to persuade/adapt the attached imp file to accept one long continuous line of text and scroll it without a break showing. between end of line and its start.

Any suggestions would be gratefully received. Scroller imp file courtesy of Robin Garrett.

Hi John,

I'd use a script. Depending on how you need it set up, simply use substring to extract part of the orginal string and concat it to the end of the original. Here's one variation:

function Scroll()
{

for (i=0;i<1000000000;i++)
{
aStr = myText.substring(1,myText.lenght)
bStr = myText.substring(0,1)
myText = aStr + bStr
wait(0.1)
}
}

Thanks Mack,

Scripting is definitely not a strong point for me!

I'm trying to present (on show of a page) a single long line of text that continuously scrolls and re-scrolls without a break showing between end of the line of text and its restarting.

With your script it seems to require two lots of substrings - or am I reading it incorrectly? Not sure but I guess it requires me to set up mystring = "all the text I want to continuously show"

"simply use substring to extract part of the orginal string and concat it to the end of the original" - not sure what you are saying here given what I want to do. Think the sample imp I attached might be confusing to the reader. It uses two sets of text - I wanted to amend it to use a single text box whose contents continuosly scroll.

Bet I've confused the hell out of you now!

John --

My first thought was to have TWO Text Objects, then I download your example and I see on Page 1 that's exactly what the creator did. Why is that not acceptable? If the text is longer than what's in this example, then you have to adjust the "Amount" under Simulatenous Action Group under the "On Show" Trigger.

Fred,

Thanks for responding.

My piece of text is 2480 wide. So I had already tried replicating two copies of that text and adjusting the Amount as suggested. Screen text does not scroll when I test it - hence my query.

Strikes me there ought to be a simple way of getting a piece of text to repeatedly scroll across the screen! Thought I had found it - but I cannot get it to do what I want.

Hi John,

1. Create a textbox and insert a variable called myText

2. Create an OnShow trigger. Attatch a the script action from the programming tab. Enter Scroll() in the script box.

3. Add a script object to the page. In the script editor add the following text:



Sorry if this oversimplifies things, but it should work. As i've got Opus VI, I wasn't sure whether it could be open in v5?

Mack

Thanks Mack,

Got it working - almost (!) on first attempt.

Before the 'next' word appears spaces are shown on screen and then the word 'jumps in' and fills the spaces. Can this be overcome so each word appears letter by letter? At the moment it gives a very jerky appearance to each word as it apears.

If I'm asking too much - just ignore me and I'll accept the small miracle you have worked with good grace!

All the best.

John

Hi John,

Can you post or email your version with the text your using. It's not the smoothest method, but shouldn't be too bad - not sure about the space.

I've have a look though.

Mack

Update. This issue above is caused by using large sized fonts. Something to do with wrapping around to the next line. There doesn't seem to be any way around this with a textbox (?) BUT if you change to using a text input box, you can limited it to a single line.

Add an invisable frame with stop m-clicks passing through to prevent editting.

Mack

Mack,

Very many thanks - works perfectly. Much appreciated.
