  How can i change the Text Size and change the Character Style in especific letter

  Posted by Adrián Wulfrath on June 9, 2015 at 7:08 pm

  Hello, i have this code for a blinking writting text:

  L = text.sourceText.length;
  T = time*effect(“Speed”)(“Slider”) – effect(“Start At”)(“Slider”)*effect(“Speed”)(“Slider”);
  F = Math.round(time % 1);

  if(F == 1 | (T0) ){Fl = “|”;}else{Fl=” “;}

  substr(0,T) + Fl

  But i want to personalise the size of the Blinking Cursor “|” change the size and change the character style just for that cursor. How can i do that?

  L = text.sourceText.length;
T = time*effect("Speed")("Slider") - effect("Start At")("Slider")*effect("Speed")("Slider");
F = Math.round(time % 1);

  if(F == 1 | (T0) ){Fl = "|";}else{Fl=" ";}

  substr(0,T) + Fl

  I can’t think of any way to do that directly in one expression, but you could have another text layer with the cursor and keep it positioned to the right of the visible text using sourceRectAtTime().

  So how can i use that correctly?

  Add another text and put that expression in Source Text?

  Sorry, I’ve been fairly inaccessible for the last couple of days(jury duty).

  You would apply something like this to the position property of the cursor layer:

  xOffset = 15;
  yOffset = -25;
  L = thisComp.layer(“text”);
  rect = L.sourceRectAtTime(time,false);
  L.toComp([rect.left+rect.width,rect.top+rect.height]) + [xOffset,yOffset];

  Adjust xOffset and yOffset to get it just where you want it.

  Presumably, you would apply your alternating ” ” and “|” to the source text property.
