Layout Asset Frame JSFL

Here’s a handy command I created a while ago, but recently upgraded. It takes all the elements on stage in the current frame and lays them out neatly in a grid according to their size.

Why would you ever want to do such a thing? Two situations:

A. You are making a component. You have an assets frame with all your attachable symbols in it.
B. You are making an application where, in order to have a preloader, you do not export your assets first frame, and therefore need to include the assets in a frame somewhere to force them to be exported.

I do both pretty often and always just dump everything into the frame randomly. Sometimes I’ll use the alignment tools to neaten things up a bit. But it’s tough to tell quickly which assets are in the frame. I’m always dragging them here and there searching for a particular one. Kind of like digging through your sock drawer looking for your other green sock. All this command does is neaten things up for you so you can see everything in the frame.

Anyway, without further ado, here’s the command:
(It’s also pretty useful for demonstrating a few cool JSFL techniques.)

maxHeight = 100;

padding = 5;
// get current frame

_doc = fl.getDocumentDOM();

_tl = _doc.getTimeline();

currLayer = _tl.currentLayer;

currFrame = _tl.currentFrame;

_frame = _tl.layers[currLayer].frames[currFrame];
// put the elements in this frame into an array

elems = _frame.elements;

numElems = elems.length;

===
_doc.scaleSelection(scale, scale, "top left");

}
// if beyond right side of stage, make new row

if(dx + _elem.width > _doc.width){

dx = 0;

dy += Math.min(maxHeight, h);

}
// move to new position

_doc.moveSelectionBy({x:dx+2, y:dy+2});
// update variables

dx += _elem.width + padding;

h = _elem.height;

}
// custom height sort function (no sortOn available)

function heightSort(arr) {

var sorted = false;

while(!sorted){

sorted = true;
