Shape position after drag

[Tony Morgan]

Hi. I'm a newcomer to Snap, so please excuse my ignorance.

I have functions that need the current position of a shape. If I access the x,y coordinates for a shape I get the location where it was originally defined, not where it is right now. How can I get the current position of a shape that might have been dragged?

If its been dragged you probably need to look at the transform and it's matrix. I think matrix.split() will provide dx and dy which is it's translation. 

So something like     someElement.transform().localMatrix.split().dx   &    someElement.transform().localMatrix.split().dy

This supposes that the drag is simple, no rotations, scales etc.

Just to add, if you are doing the drag code yourself, you may find it easier to just store whatever drag you are doing in a variable! I'm assuming you can't do that with my previous response.

A found a simple solution, which is to use getBBox on the moved shape and work from the BBox coordinates.
