  scripting question: link expression in script

  Posted by Danni Runitz on August 28, 2015 at 2:02 pm

  Hey!

  I’m new to scripting and can’t get my first code done.

  Within my script I’ve been able to create 4 slider to the text layer, but can’t get my expression into the “soure text”.

  this is the expression I want to write in there:

  startT = effect(“StartFrame”)(“Slider”);
  endT = effect(“EndFrame”)(“Slider”);
  beginVal = effect(“BeginVal”)(“Slider”);
  endVal = effect(“EndVal”)(“Slider”);
  t = linear(time,startT,endT,beginVal,endVal);
  t.toFixed(0)

  How do I tell program to write that in the “source text” expression

  help pls?

  That would look something like this:

  
var myTextLayer = app.project.activeItem.layer(1);
var myExpr = 'startT = effect("StartFrame")("Slider");\r' +
'endT = effect("EndFrame")("Slider");\r' +
'beginVal = effect("BeginVal")("Slider");\r' +
'endVal = effect("EndVal")("Slider");\r' +
't = linear(time,startT,endT,beginVal,endVal);\r' +
't.toFixed(0)';

  myTextLayer.property("Text").property("Source Text").expression = myExpr;
