Description

When I try to plot the agent position over time using DEBUG.POS.TRANS and overlay the trajectory over the top-down view of the map using DEBUG.CAMERA.TOP_DOWN, they don't seem to match up.

What exactly do values in DEBUG.POS.TRANS represent and how can I find their ranges? Is there any good way to overlay the trajectory on the map?
