When I get symbol positions currently it gets them relative to where they started on the stage.
How can I get their absolute position on the stage? So if 2 symbols are in the exact same position on the stage - that's the position they'll report?
position() returns values relative to the elements parent whereas offset() returns values relative to the document.
Try offset which might solve your problem
I think I gave you a sample with offset(). Did this not work for you?
Here is a sample with css and offset. Note that css return a value with px like 100px and offset() returns the value as 100. So with css if you are doing calculations you will need to parse the value.
