  cs6 scripting – toggle all proxies – can’t find a “ProxyExisting” value

  Posted by Adam Seeley on November 2, 2012 at 4:28 pm

  Hi,

  Help! 🙂

  I’m very new to scripting in AE (Although have used lot’s of OM type stuff using VB in Softimage).

  I want a simple script to toggle all proxies on & off.

  I’ve dragged my slowly melting brain as far being able to loop through all project elements & turn proxies off, as AE will turn a proxy off whether or not one exists.

  I haven’t found a way to test if there’s an existing proxy to turn one again. The script will stop if there’s no existing proxy attached to a project item.

  Any help would be gratefullt recieved.

  Cheers,

  Adam.

  {
// ams_ToggleAllProxies.jsx
//
// This script one day will toggle all proxies on & off.

  function ams_ToggleAllProxies()
  {

  clearOutput()
  writeLn("ams ToggleAllProxies");

  var oItems = app.project.items;
  var totalItems = oItems.length;
  var temp=1

  writeLn("Number of items is: "+ totalItems)

  for (var i=1; i<oItems.length; i++) {
  $.writeln("item:[" +i+ "] is " + app.project.item(i).name);
  $.writeln("proxyFlag:[" +i+ "] is " + app.project.item(i).useProxy);

  // I WANT TO CHECK A VALUE OF THE PROXY PATH TO SEE IF A PROXY EXISTS BUT I DON'T KNOW HOW.
  //$.writeln("type:[" +i+ "] is " + app.project.item(i).proxySource.path);

  // JUST AN "IF" FOR WHEN I HAVE A PROXY-EXISTING TYPE VALUE TO TEST.
  if (temp=1)
  {
  $.writeln("AAGHH")

  // THIS DOESN'T WORK WHEN NO PROXY EXISTS AND STOPS THE SCRIPT
  app.project.item(i).useProxy=true

  // THIS DOES WORK AND TURNS OFF A PROXY WHETHER THERE'S ONE IN USE OR NOT - HALF WAY THERE
  //app.project.item(i).useProxy=false
  }

  }
  alert("Proxies Toggled")
  }

  ams_ToggleAllProxies();
}

  I haven’t tried it, but I think you should be able to do this:

  if(app.project.item(i).proxySource == null) continue; // skip to end of loop

  Brilliant, thanks for that…. works perfectly.

  Always tricky getting just the right syntax when your’e learning a new language.

  I now have two scripts, one for turning all proxies on & one to turn them off.

  I can’t believe it’s not already a feature for a hotkey!

  Thanks again,

  Adam.

  Hi,

  would you be able to post these two scripts?
  I’m looking for exactly that and can’t find it anywhere.

  That would be great!

  Thanks

  Hi,

  And why not…

  Here’s the script to Toggle All Proxies OFF

  Save it into

  ams_turnAllProxies_OFF.jsx

  and stick it into the

  C: -> Program Files -> Adobe -> Adobe After Effects CS6 -> Support Files -> Scripts”

  Folder

  Hope it works for you,

  Adam.

  {
// ams_ToggleAllProxies_Off.jsx
//adam_seeeley@yahoo.com
// This script one day will toggle all proxies on AND off.

  function ams_ToggleAllProxies()
  {

  clearOutput()
  writeLn("ams ToggleAllProxiesbbb");

  var oItems = app.project.items;
  var totalItems = oItems.length;
  var temp=1

  writeLn("Number of items is: "+ totalItems)

  for (var i=1; i<oItems.length; i++) {
  $.writeln("item:[" +i+ "] is " + app.project.item(i).name);
  $.writeln("proxyFlag:[" +i+ "] is " + app.project.item(i).useProxy);

  //if(app.project.item(i).proxySource == null) continue; // skip to end of loop
  app.project.item(i).useProxy=false

  }
  alert("Proxies Toggled")
  }

  ams_ToggleAllProxies();
}

  And for turning them all on again…..

  save into a text file:

  ams_turnAllProxies_ON.jsx

  Hope it helps.

  Adam.

// ams_ToggleAllProxies.jsx
// adam_seeley@yahoo.com
// This script one day will toggle all proxies on AND off.

  function ams_ToggleAllProxies()
  {

  clearOutput()
  writeLn("ams ToggleAllProxiesbbb");

  var oItems = app.project.items;
  var totalItems = oItems.length;
  var temp=1

  writeLn("Number of items is: "+ totalItems)

  for (var i=1; i<oItems.length; i++) {
  $.writeln("item:[" +i+ "] is " + app.project.item(i).name);
  $.writeln("proxyFlag:[" +i+ "] is " + app.project.item(i).useProxy);

  if(app.project.item(i).proxySource == null) continue; // skip to end of loop
  app.project.item(i).useProxy=true

  }
  alert("Proxies Toggled")
  }

  ams_ToggleAllProxies();
}
