in a routine I have a bunch of polygons, that the participant can move by clicking on them and dragging with the mouse. I want to save the final position of these polygons, but using .pos (e.g. thisExp.addData(“final_pos”, myPolygon.pos) saves the coordinates in this format: [xy] (e.g. [-0.25 -0.3 ]).
Is there a way to save this information as a number? Preferably as two separate numbers: (e.g. final_pos_x = -0.25, final_pos_y = -0.3)
