Is it just going to be an animation? Or can the person actually control how fast the cart is going. If it is just an animation, then you have to do everything yourself. If there is a curve in the tracks, you have to say in the method "turn cart right 0.3 revolutions", or whichever way it is turning and at what angle. And have it in a Do Together block with the cart moving forward, so both happen at once. It will take a long time, especially if it is a long track, but it is way easier than creating a physics engine for the cart to have it move like that. O.o I don't even want to think about how long that would take.

You can use "move object forward", you can use "turn object", and thats about all you need to do, assuming that there are no twisty loops in the roller coaster, in which case you could use "roll object". Other than that, do trial and error, one step at a time until you have it set up the way you want.

The roller coaster is a popular amusement ride developed for amusement parks and modern theme parks. LaMarcus Adna Thompson patented the first coasters on January 20, 1885. In essence a specialized railroad system, a roller coaster consists of a track that rises in designed patterns, sometimes with one or more inversions (such as vertical loops) that turn the rider briefly upside down. The track does not necessarily have to be a complete circuit, as shuttle roller coasters exhibit. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars.
