Instantly Swap Left and Right Tags in Illustrator [Download Free Script]

Download a free script to switch between the left and right tags of layer and object names in Adobe Illustrator. Make your workflow fast and simple.

In this post, you will find one more script that can make your workflow of making illustrator puppets for Adobe Character Animator faster and easier. The script attached here will help you automate the process of mirroring right/left character views by swapping the left and right tags in the names of all the elements.

Using this “Swap Left and Right tags” script together with the “remove copy suffix from all layers ” script (posted earlier) may help you save hours of tedious work. 

The Main Idea

Change all layer names and object names to include the word left instead of right and vice versa. 

The Problem Explained

For a puppet to work properly in Adobe Character Animator it should follow a very specific hierarchy and naming convention. One of the rules of this naming standard is that the different facial and body elements of the illustrated character should have right and left tags in their names.

Facial features that are named properly are recognized by Adobe Character Animator automatically and save lots of extra rigging work. For example, an right eye should be named as +Right eye. Below it in the hierarchy there should be right blink, +right pupil, right pupil range etc…

So if we copy the left quarter facial view for example and mirror it to turn it into a right quarter facial view, we will need to find all the tagged layers and rename them. It is possible to do it manually, but it may take some time and effort.

The script in this post is created to automate this process. So once you highlight the top layer of the view you want to swap and run the script, all the left tags will turn into right tags and all the right tags will turn into left tags. All in a single click.

How to Use this Script

You should now have a hierarchy with renamed layers. So If you selected to run the script on the “right profile copy” layer: the layer itself will become “left profile copy”. All the layers and items containing the word “right” in their name will also change:

The above items will now be named:

Script Logic Explained

You can skip this section if you don’t like coding.  

The script goes over all layers  and items which are placed in the hierarchy below the highlighted layer. It finds all the sublayers and items containing the word left and right in their name. Once all the items are located, the script goes all of them, finds the string matching left or right and replaces it with the opposite one.

					if(!layersList)
  {
  layersList=  app.activeDocument.activeLayer.layers;
  checkLayerTagLeft(app.activeDocument.activeLayer);
  checkLayerTagRight(app.activeDocument.activeLayer);

  app.activeDocument.activeLayer.hasSelectedArtwork=true;
  var topsel=app.activeDocument.selection;
  checkSelectedItems(topsel);
 
  }
				
			
				
					for (var i = 0; i < layersList.length; i++) {

            layersList[i].hasSelectedArtwork=true;
            var sel=app.activeDocument.selection;
            checkSelectedItems(sel);
            checkLayerTagLeft(layersList[i]);
            checkLayerTagRight(layersList[i]);
          


      if (layersList[i].layers.length) findLayersWithLeftAndRightTags(layersList[i].layers)
    
    
    }
				
			
				
					swapLeftAndRightTags();
				
			
				
					function swapLeftAndRightTags(){
  
  
    for (var i = 0; i < layersWithLeftTag.length; i++)
    {

      layersWithLeftTag[i].name = layersWithLeftTag[i].name.replace('Left', 'Right');
      layersWithLeftTag[i].name = layersWithLeftTag[i].name.replace('left', 'right');
      numOfLeftTagsChanged++;
    }

 
    for (var i = 0; i < layersWithRightTag.length; i++)
    {

      layersWithRightTag[i].name = layersWithRightTag[i].name.replace('Right', 'Left');
      layersWithRightTag[i].name = layersWithRightTag[i].name.replace('right', 'left');
      numOfRightTagsChanged++;
    }

 
    for (var i = 0; i < itemsWithRightTag.length; i++)
    {

      itemsWithRightTag[i].name = itemsWithRightTag[i].name.replace('Right', 'Left');
      itemsWithRightTag[i].name = itemsWithRightTag[i].name.replace('right', 'left');
      numOfRightTagsChanged++;
    }
    
    for (var i = 0; i < itemsWithLeftTag.length; i++)
    {

      itemsWithLeftTag[i].name = itemsWithLeftTag[i].name.replace('Left', 'Right');
      itemsWithLeftTag[i].name = itemsWithLeftTag[i].name.replace('left', 'right');
      numOfLeftTagsChanged++;
    }
