  Grabbing source.Text from one layer and incorporating it into a layer with an expression

  Posted by Richard Torres on August 2, 2012 at 3:17 pm

  Hey Guys,

  This is my first post so any help will be appreciated. I’ve been piecing together an expression for a text layer. It should simulate typing and deleting (expression attached) while controlling the start, duration and animation speed. Now I need that expression layer to use the text from another layer in a different comp. Does anyone know how I can integrate that into my code?

  Thanks,

  F=Math.round(time%1);
L=text.sourceText.length;
T=time*thisComp.layer("Controller Sliders").effect("Speed")("Slider")-thisComp.layer("Controller Sliders").effect("Start at")("Slider")*thisComp.layer("Controller Sliders").effect("Speed")("Slider");
D=thisComp.layer("Controller Sliders").effect("Start at")("Slider")+thisComp.layer("Controller Sliders").effect("Duration")("Slider");

  if(T>L){(R=L)}else{R=T};
  if(time>D){(E=0)}else(E=1);
  if(time>D){(G=L-(time-D)*thisComp.layer("Controller Sliders").effect("Speed")("Slider"))}else(G=0);
  if(F==1|((R0)|G>0&G<L){Fl="_";}else{Fl=" ";}

  substr(0,(E*R)+G)+Fl

  Try this:

  myText = comp("Name of Comp").layer("Name of Layer").text.sourceText;
L = myText.length;

  F=Math.round(time%1);
  T=time*thisComp.layer("Controller Sliders").effect("Speed")("Slider")-thisComp.layer("Controller Sliders").effect("Start at")("Slider")*thisComp.layer("Controller Sliders").effect("Speed")("Slider");
  D=thisComp.layer("Controller Sliders").effect("Start at")("Slider")+thisComp.layer("Controller Sliders").effect("Duration")("Slider");

  if(T>L){(R=L)}else{R=T};
  if(time>D){(E=0)}else(E=1);
  if(time>D){(G=L-(time-D)*thisComp.layer("Controller Sliders").effect("Speed")("Slider"))}else(G=0);
  if(F==1|((R0)|G>0&G<L){Fl="_";}else{Fl=" ";}

  myText.substr(0,(E*R)+G)+Fl
