Railroad game quick start.

Hi. I would like to create a railroad-based game, but I have a very vague idea of how to "build" a railroad and make the train follow the rails. I spent a couple of hours in the Asset Store, but didn't find a working example. There are several car-racing projects, but I suspect that moving a train along the railroad will be somewhat different.

Can somebody give me an idea where to start? Some example code would be great. Thanks!

 

Hi!

Well, we built a game based in railroad and exist too many ways to work around. I'll tell you 2 of I tested:

1- Raycast
You create a "main trail" and put your car above with one (or more) raycast to down and rotate according to normals. Apply some force to forward.

2- Follow Line
This way is nothing special, its more fast to prototype but you have some limitations. You create a spline and put your car to follow. You cant change directions rotations, etc. But, you can divert this limitations.

There are some Spline assets in the store which will help you create your paths and move objects along them, some are better than others at various things, one of them does even have a helper script for moving train objects along a spline.

 

Thanks everyone for the suggestions! I wonder if there's any significant difference between a train following a railway and a car automatically following a road. I think the tricky part is making all the wheels stay exactly on the rail.
