C is play the AI vehicle V is change the barrier (this doesn't work, will be fixed in 2.0)
Contact me if you want to use the code, however integration for this to work well will be difficult. I am currently working on 2.0 for my own game. -------------------- So this isn't a game. It's demonstration of scratch principles. It's very rudimentary, and isn't very visually appealing. I will update it to make it look at bit better so it is a bit easier to understand.
