  Cursor for Type On Effect

  Posted by Aaron Williams on April 27, 2022 at 3:40 pm

  It sounds simple but I’m having a hard time getting this to work right. I just want a non-blinking cursor to wright on text, often in multiple lines. Then the option of the cursor to erase it all again. I have gotten real close using a few methods. This one I think give the most flexibility for what I want to do.

  The problems are with line breaks in paragraph boxes: The text will start typing on the first line until in runs out of room then jumps the current word to the second line and finishes typing. I could manually add a line break, but it then breaks the cursor because line breaks must count as a character and throws the whole thing off.

  I’m not that hip on the programing. I took a blinking cursor script and changed it enough to replace the empty space with the same character. Don’t make fun of me too bad 😉

  Source Text

  var sign = "|";
  var blinkInterval = 15;
  var i = effect("Text")("ADBE Slider Control-0001");
  var on = effect("On/Off")("ADBE Checkbox Control-0001");
  var frames = timeToFrames(time);
  var check = frames / blinkInterval;
  if (on == 1) {
  	if (i.valueAtTime(time + thisComp.frameDuration) > i){
  		end = sign;
  	} else {
  		if (Math.floor(check) % 2 == 0) {
  			end = sign;
  		} else {
  			end = "|";
  		}
         }
  } else {
  	end = " ";
  }
  text.sourceText.substr(0,parseInt(i)) + end;

  Range Selector 1 > Start

  text.animator("ADBE Text Animator")("ADBE Text Selectors")("ADBE Text Selector")("ADBE Text Index End") - 1;

  Range Selector 1 > End

  text("ADBE Text Document").length;

  In the Effects there is the Slider, Checkbox, and Color picker.

  Any help would be great. Thank you!
