Alright, forgive me, I'm a bit of a newbie here.
I'm making this little game where you race a car around a track, and try to get the best lap time. It's basic. Anyways, I have a start/finish line. I have it set up so each time the car runs over the line, it makes the car's private variable 1.
Anyways, after running debug mode, I noticed every time the car would pass the finish line, the variable would stay at 1. I want it to (each time the car passes) INCREASE the variable by one. I tried +1, but that doesn't work. -1 does, though. What do I need to do to increase the variable by one each time the car passes over (collides) with the finish line?
