looping news ticker template creation

[Dan Ebberts]

You can get the character count of a text layer this way:

thisComp.layer(“your text”).text.sourceText.length

This thread discusses a hack, using sampleImage() that will give you the left or right edge of the text:

Other than that, you’d have to use a script, which does have access to the actual extents of the text in a text layer.

if i under stand what you are trying to do — just have a line of text crawl across the bottom of the screen — then i don’t think you need to know the width.

i think you could time to offset the position with an expression like this:

offset = 2; // value in pixels per frame
x = timeToFrames()*offset;
value – [x,0]

it will march across the screen for as long as the comp’s duration.

and to make the source text string loop, you could use an expression like this:

value + ” ” + value + ” ” + value;

just keep adding + ” ” + value to make the string loop.

if you want a ticker to look like fox news where it wraps around, just add effect-distort-offset and add this to shift center, creating an infinite wrap-looping ticker.

Did you try something like this?
Seems like what you are trying to do….


txt = thisComp.layer("text");

w = txt.sourceRectAtTime(time,true).width;

border = 10;

s = (w + 2*border)*100/width;

[s,value[1]]
