ok, i got it and i made want i wanted. finally. thank you!!! the only thing is that i really can't understand how to close this spawn points window in the editor. but anyway, i just saved the map and quit and it's ok. i put all the interval values to 2. highways to 1. that's cool. i have a REAL-life highway and traffic-full streets. ofcourse a couple of places need attention, but placing three cars = 6 cops on three most jammed intersections without traffic lights sorts any problems. i just block one street and let another pass, then change. ofcourse the game missions cannot be played, so i just waited for an ambulance mission and just enjoy the traffic-ergency 4 ))) thanks!
