Apply pattern swatch to object and retain pattern rotation

[Katrina2023]

I have a script that will apply a pattern swatch to the objects I want, but when I do, it resets any changes I have made to the scale or direction of the pattern. For example, I have a front and back object, the pattern on the front needs to be right side up and the back upside down. Is there a way apply the pattern and retain the orientation that I have previously given the object? Here is what I have:

var doc = app.activeDocument;

var swatchFrontIndex = doc.swatches.length - 1;
var swatchBackIndex = doc.swatches.length - 2;
var swatchFront = doc.swatches[swatchFrontIndex].color;
var swatchBack = doc.swatches[swatchBackIndex].color;
var numbOfLayers = doc.layers.length;
var designLayer = doc.layers[numbOfLayers - 1];
var numbOfItems = designLayer.pathItems.length;

try{

for(j = 0; j < numbOfItems; j++){

if(designLayer.pathItems[j].name == "Front"){

designLayer.pathItems[j].fillColor = swatchFront;

}

if(designLayer.pathItems[j].name == "Back"){

designLayer.pathItems[j].fillColor = swatchBack;

}

}
}catch(err) {}

would rotating the pattern 180 degrees work for the "Back"?

if so, after applying the swatch use

designLayer.pathItems[j].rotate (180, false);

That would work for one instance, but I have a variety of artboards that have different angles and scales. Would there be a way to build into the script to know which scale and orientation to apply to a given artboard?

[CarlosCanto]

yeah, it can be done in different ways, depending on how your art is set up (or maybe you need a new setup suitable for automation)

basically we would need to pass "name", "rotation", "scale" to the script, for example if the pieces had names like "Back-180-100", you would get the pathItem name, split the string at each dash to get ["Back", "180", "100"], then you would apply the Swatch, Rotation, Scale based on those numbers. Instead of using If-Else.

But the above process would require renaming your pieces, if that's not doable then we would need to find a way to come up with that info based on where they are, but that would need structure. So the file might need some prepping.

I can rename the pathItems. That would work great. Thank you!
