To make the canal go further inland then you need another extra "Inland canal2" requiring "ExtraFlag", "Inland canal", "CAdjacent", which again only gets you one more tile, so then you need another extra "Inland canal3" requiring "ExtraFlag", "Inland canal2", "CAdjacent", etc. The ideal solution would be to have multiple reqs that allow Canal next to Oceanic, River or Canal. The issue of requirement vectors has been discussed in a couple other threads - http://forum.freeciv.org/f/viewtopic.php?f=11&t=91457 and http://forum.freeciv.org/f/viewtopic.php?f=13&t=551

My idea was to make one extra flag for both "coast" canal and inland canal (and probably rivers), so you can start inland canal from any suitable extra and continue infinitely, and "coast" canal will start from an oceanic terrain in absense of such an extra. (Also, if any bonuses
other than movement are provided by a canal, you probably should put river and other canal type into negated local requirements).
Huh, trade bonuses would be natural for canals, they are often built just to carry cargo ships, and so Freeciv concept of "trade" works that you increase it just from roads to nowhere. We can use civ2civ3 hack that most trade goes from routes and caravans to establish them move only by roads, but we probably don't want. Also, maybe if we have invented channels here, we should disable irrigating from irrigation and enable irrigating from a canal.

Gave it another try and failed again. Problem is that custom flags defined for terrain can't be used by extras. Extras can only have flags from the list of pre-defined extra flags.

Dino the Dinosore wrote: An argument could be made that a Canal should give a trade bonus like a River does, but I did not do that because then you could add a Canal to tiles worked by a city just to get that trade bonus, which seems wrong.

In Civ I, you only get the trade bonus once for road and/or river. You could add canals to that list.

Well, yes... but, as a kludge, some of the flags will not do much harm (e.g. "ConnectLand" or, if no defense value given, "NaturalDefense"), maybe some of them will do the thing

edit: oops, custom extra flags are already done in v.3.0

Thanx, Ignatus - it's a kludge for sure but it works! The "ConnectLand" extra flag is not used by any ruleset AFAIK (wonder why it's there), so I tried it and it does the job. I have edited my first post in this thread to have an updated zip file which now has an "Inland Canal" in addition to "Canal" so canals can be longer.

Ow, they explained me how it should be done: you put
* into extra_canal.reqs: "TerrainClass", "Land", "Local",
* into road_canal.first_reqs: "TerrainClass", "Oceanic", "Adjacent"
* into road_canal.integrates: "River"
If you have specified any first_reqs for the 'road', it won't be built unless either similar/integrated road is near (cardinally adjacent if move mode on the road in question is cardinal or relaxed, adjacent if the road is always fast), or the first_reqs are fulfilled alongside with extra reqs.

I don't know much about rulesets.
Maybe adding rules like this:
A.
1.Connect: A->B
2.Connect: B->A
OR:
B.
1.Connect:A->B
2.Connect:B->C
3.Connect:C->A

Now that "Inland Canal" is working, I have found some consequences to deal with.
1 Having e.g. Battleship or AEGIS Cruiser in a canal warps land combat. Fixed with change in effects.ruleset to give 50% defense penalty to Sea class units in a canal, which is realistic.
2 Having a canal should enable irrigation in adjacent tiles. Added fix in effects.ruleset.
3 Found that a canal next to a non-coastal city enables the city to produce naval units - not a problem. Added to help text.
4 Found that a canal next to a non-coastal city does not enable the city to build any improvements - again, not a problem. Added to help text.
5 Canals and bases (Fort, Airbase, etc) should not be allowed on the same tile. Made changes to reqs in terrain.ruleset.

Updated the zip file in my first post in this thread.

I've just discovered that the game.ruleset file can have a section e.g. This means I don't have to use a modified amplio2.tilespec file, so I've reorganized my stuff to make it easier to install. Just download a zip file, un-zip it, and put the 3 files contained in the resulting folder into your share/freeciv folder or ~/.freeciv/2.6 folder.

I have also figured out to make them into modpacks - can anyone help me get them onto the "modpack.freeciv.org" server?

Do you have .mpdl files for these? What is the difference between dino and dino2?
