  Writing “Alert” to Text File

  Posted by Ben Christie on December 3, 2015 at 7:41 pm

  Hey guys,

  So currently I have a script working pretty well that pops up an alert within after effects with my results.

  What I’m looking to do is keep that as it currently is but now add another button that the user could click to write that same “alert” information to a text file on the desktop.

  I’m having trouble making the connection of how to do that.

  Suggestions?

  Thanks!

  This should help:

  var myFileName = “Example.txt”;
  var myFilePath = “~/desktop/” + escape(myFileName);
  var myMessage = “Hello world!”;
  var myFile = new File(myFilePath);
  myFile.open(“w”);
  myFile.write(myMessage);
  myFile.close();

  Dan,

  This is exactly what I’m looking for!!!

  Is there a way to name the text file your AE project title automatically instead of example?

  Would I use the following code somehow?

  Thanks!

  myProjName = app.project.item(index).name;

  Hey Dan,

  Also this is similar question in relation to the alert that you might be able to help with.

  I have the following code that works really well at getting the information from my function but it keeps over writing the file with the new keyframe if I have five keyframes. If I have one it works well but if I have multiple they over write each other. I’m sure it’s because of the way I am calling the information from my function but I’m not sure how to fix it.

  Any help would be great. Thanks!

  var myFileName = "example.txt";
var myFilePath = "~/desktop/" + escape(myFileName);
var myMessage = "keyframe: " + i +" Cubic-bezier["+x1r+", "+y1r +", "+x2r+", "+y2r +"]";
var myFile = new File(myFilePath);
myFile.open("w");
myFile.write(myMessage);
myFile.close();

  Shoot I’m pretty sure it has to do with the fact that I’m looping a script to get each keyframes curve, and the keyframe is called “i” each time so it just overwrites itself.
