Enable physics when cart is off-rail

[R-0ne]

Hello,

Would it be possible for the cart to leave normal rails if it does not meet a stop rail for example ? this would allow to drop the cart several blocks at once to fall back on rails for theme park maps for example.

thank you

The cart does not have physics enabled for the reason that it would break while going up- and downhill. However, it would be possible to turn that on as soon it's no longer on rails. Additionally do many cart railways rely on the behaviour that the cart stops when there's no rail to continue moving, so it should be an optional feature unless it's acceptable that carts slide away several nodes (depending on max speed).

I feel like making railways add a break or start/stop rail is a small price to pay for being able to have much more flexible cart routing and distribution.

Does that work reliably? I had great problems with cart passing several air nodes on a laggy server.

Anyway, I’d prefer to have explicit buffer stops do the job. These are nicer and more natural.

@numberZero boost_cart does not skip rail node checks (any more) due to the pathfinder algorithm I implemented a while ago. So either it's caused by an outdated clone or by a new, yet unhandled case where the cart moves but on_step is not called.
However, it's still possible that the cart does not stop at start/stop rails because the pathfinder only checks whether there are continuous rail nodes.
