i was at my friends server and he had 4 vehicles out on a spawn. when a got in them, we could drive up walls and ceiling and stuff. i asked him how and he said he edited the script by putting gravity jeep script into the vehicles we were using scripts. how would you do that?

you take the script from gravity jeep that let's it go on walls and junk and put it into the script of the other vehicle?
