[ottd] Best spec to vary ship speed by water tile class?

[andythenorth]

Use ship prop 14/15?

Or extend cb36 to run more often, and provide a new var for checking water class of current tile?

Question about best spec, not nfo/nml implementation.

This is in connection with some ponies

a) If prop 14/15 suit your needs, then use them. They are available as stated in the specs.
b) If prop 14/15 do not suit your needs, then explain what interactions between canal/sea and speed are missing.
c) If you want to treat river/canal differently, I am against it

"realistically", rivers would have a flowing speed which gets added/substracted from ship speed.

You mean there is no current in canals?

The maximum speed is already updated with CB 36 when water class changes, only a var for water class is missing currently.

Most canals are guarded by locks. As a result, there's much less current through a canal than through a river. Of course, there may be exceptions.

So if you really wanted to implement this properly, the game should check whether a canal has a lock or not and decide the current based on that. But that's probably too much effort for too little benefit. This is a game after all

Conclusion was:

- use prop 14 / 15
- extending cb36 is a bad idea
