in code make a DIRSTEP (in iterates) from map coordinated in the code of
generator
this call data from DIR_DX, DIR_DY
if you work in map coordinates (ISO) and you want make a step to the E
you need a DX=+1 and ad DY=-1 no the values DX=+1, DY=0 called by
DIRSTEP for a step to N or S these is more complex you need to make a
new mapstep, DIRSTEP is only to be used in natural coordinated
