  valueAtTime preexpression bug when used on paths?

  Posted by Arne Münch on June 21, 2020 at 12:44 pm

  Hello there

  valueAtTime(time, preExpression) in scripting seems not to work when used on paths. The preExpression parameter acts always like it is false.
  Can you please try for me, I tested on cc2018 and cc2020 and this script creates a keyframe after calculating the expression, so the original path has changed, but this shouldn´t happen:

  var actItem = app.project.activeItem;
  var selProps = actItem.selectedProperties;
  selProps[1].setValueAtTime(0, selProps[1].valueAtTime(0,true))

  For testing purposes you can just use this expression on a path and test if the script changes the original preExpression path (by selecting the path property and running the script), which it shouldn´t.

  originalPath = thisProperty;
  createPath([[-100,0] , [100,0]] , [] , [] , originalPath.isClosed());
