I was just wondering, that in my map, you are more or less required to enter a vehicle. So I was wondering, since its possible to put a hill around a vehicle, is it possible to do the same with a soft safe boundary so that if the vehicle is exited, you get a 10 seconds till death warning?
No, but you could put a really short one down so that you are above it when you enter a vehicle and enter itwhen you get out
This is correct. If you place a soft killzone at the proper height, vehicles can drive over it without being affected, but you will be affected on foot.
