  text field changes every frame

  Posted by Andrew Ibarra on January 13, 2011 at 7:38 pm

  Hi,

  I’m planning on creating a field of words using trapcode particular. Is there a script that will take words from a text file or from wherever, and break it up so that one word appears every frame? I’m trying to avoid typing it out every time and having 50+ text layers.

  Thanks!

  Hey Andrew…

  Maybe you can paste everything in a single text layer, then use
  https://aescripts.com/decomposetext/ to break it in layers. Trim them to 1 frame long and use after’s build in “sequence layers” command to make them work with particular later on.

  Hope this helps.

  an expression can parse out a text layer’s source text pretty easily, you just need to decide on a character to use to ‘split’ the source text. this could be any thing you want, but a space or a linefeed (hard carriage return) would be my suggestion.

  here’s an expression i used to split source text at the linefeed (‘\r’ is the ‘return’ character).

  TextArray = text.sourceText.split(‘\r’);
  ArrayIndex = timeToFrames()%TextArray.length;
  TextArray[ArrayIndex];

  my source text was just a list of names that i copy/pasted from an email into the text layer. the expression creates an array with each line being a separate item in the array. then with each frame it changes the text to be the next item of the array.
