Realy good one, i like it. 9/10

thanks

That's pretty darn awesome! That's a really clever idea, and i'd like to know how you did it.

it's all mechanical and collision layer. The mechanics are invisible just to keep things clean. For the horizontal traversals, the two opposite halves are connected by a link, with stops in the middle, and on the left side, and a spring on the right. For the vertical, there is a trigger arm on the track segment above the intersection which links to the long arm, and pulls the long arm up when the vehicle depresses the trigger arm. when going the opposite way, the long arm is pushed up, and depresses the trigger arm itself, allowing the vehicle to pass the trigger arm

Very nice! I drove it all the way around.

did you try running it around the other way?
