    Hi guys, I’m trying to repeat the text along path, but the end of the text and the beginning are connected without a space ” “. If I put “. “, then the break (space) after dot works. Is there a way to make a break without a dot, just a space.

    txt = thisComp.layer(“source”).text.sourceText+” “;

    num= 10 ;

    xRepeater = num;

    horzRepeat = ” “+txt.repeat(xRepeater); // does not work

    horzRepeat = “. “+txt.repeat(xRepeater); // space works after dot

    Thanks in advance!

    You could add 1 character that has the same width as the space (could be “-“ or “_” or “m”, whatever; it depends on the font and you can experiment to find the best one.).

    And then use a text animator to select just that 1 character and set its opacity to 0

    Hi Filip,

    Of course, I did this, added a “symbol” and made it transparent in the animator. But in any case, these are crutches for expression. Distance between words will constantly change due to repeaters, and the width of the “symbol” will not. During the cyclic animation along path (I have previously indicated to calculate the length of the path), this discrepancy is visible.I was hoping that in newer versions of Ae it is possible to put a space.

    thanks for your reply

    Right, I understand better now.

    Is it always 1 word that is repeated or a sentence of different words ?

    The number of repeats will change depending on the length of the text with the slider. The shorter the text, the more repeats. But with these changes, the gap between repetitions changes. The space is always different in this case, since Force Alignment is enabled.

    OK, this works:

    txt = text.sourceText+" \u200B";

    Unicode character 200B is a zero-width space, after the regular space, it doesn’t interfere with anything in the middle repeats, and it fixes the final margin.

    Thank you Filip! It even works without a dot “. ” !

    If you have your original Text in another Layer, you can automatically calculate the optimal number of repeats by dividing the approximate length of the Path by the width of the original Text.

    Like this:

    originalTxt = thisComp.layer("Original Text").text.sourceText;
    txt = originalTxt.value+" \u200B";
    w = thisComp.layer("Original Text").sourceRectAtTime().width;
    // get approximate length of path
    l = 0;
    precision = 10;
    txtPath = mask(text.pathOption.path.toString()).maskPath;
    p0=txtPath.pointOnPath(0, t = time);
    for (i=1; i<=precision; i++) {
    p1 = txtPath.pointOnPath(i/precision, t = time)
    l+=length(p0, p1);
    repeats = Math.max(1,Math.floor(l/w));
    style =; // make sure we also get formatting of original text

    See an example here:

    Bonus??? It is fantastic!!! Part of this expression also calculated the path length in my expression for animation, but I used this parameter for animation only. You have made a very elegant expression without extra controllers. I am grateful to you Filip!
