More Examples..
Probably the best way to figure out .DriftScript is by looking at examples and experimenting.
Make sure to look at the maps under /Dev/Maps/Custom/
Feel free to open them up in the map editor and going to:
Top Bar Menu --> Other --> Script --> /MapInit.DriftScript
and
Top Bar Menu --> Other --> Script --> /SimUpdate.DriftScript
Good Luck.. and if you still need help message BRZDRIFT on Discord
