Hey, I had some downtime at work so I decided to write this script I would have liked to have a few times in the past, and I thought I'd share it if anyone might find it useful or have any suggestions.
What it does is take a group of layers and places a copy of the layer on each count item null you've placed in the document.
I'm thinking of adding some companion scripts later for stuff like various ways to distribute the count items on the document, like based on existing layers, randomly, in a grid, so it will be a sort of primitive particle system of sorts.

//Iterates over count items list and places a random layer from the srcLayerset at its location function runInstancer(srcLayerset, destLayerset) { for (var i = 0; i < activeDocument.countItems.length; i++) { var randomIndex = getRandomInt(0, srcLayerset.artLayers.length-1) var newLayer = srcLayerset.artLayers[randomIndex].duplicate (destLayerset, ElementPlacement.INSIDE) translateLayerTo(newLayer,activeDocument.countItems[i].position[0],activeDocument.countIt ems[i].position[1]); } }
//Generates a random integer between min and max function getRandomInt(min, max) { return Math.floor(Math.random() * (max - min + 1)) + min; }
