The OBject Hit packet is now implemented. Please have a look and see if you think it is OK. This does not report wall contacts - only contacts with actual objects - like autocross objects or other polygon objects that are not available in layouts.
Wall hits will be reported with a simpler packet that will also be used to report illegal ground surfaces. Those reports will be triggered using the HLVC code.
