Irrigation through Hills with Cities?

[Kuciwalker]

I don't see any reason for it to be one way or the other.

Yes, I can confirm it.

You can irrigate through a city built on a hill in Conquests.

I was rather surprised to find that out myself...

Surprised?

I was surprised when I read that you were surprised, especially since I clearly remembered a PtW game (v1.27f) where I did exactly this.

Luckily I found the save, and after pillaging the irrigation that I had just set down through the hill city some turns earlier, you can clearly see that the worker can irrigate that grass tile. There is no nearby water except the coast, and I am on Printing Press (so no Electricity!). The game has not been modded in any way.

In fact, when I started searching for the save, I thought that perhaps this 'bug' had been in v1.21f, and been changed for the latest version. However, in whichever version I started this game in (99% certain v1.27f, remaining 1% chance of v1.21f) it was possible to irrigate through hill cities, and it is possible again when loaded into PtW v1.27f.

Any explanation to this, or has it ALWAYS been possible to irrigate through Hills?

Well, if you can place a city there, why not using the tile as a link in your irrigation network?

I like it, it helps the human a bit. The AI can irrigate everywhere, even before electricity. Which gives the peculiar strategy of waiting to capture a dry area until the AI has started with irrigation there...

There's something about that coast line that made me think. Without irrigating that tile, try moving your worker 8 of where it is now and see if you can irrigate that one. I might be wrong, but the game might consider the blob of water 9 of your current position to be a lake. I have seen such lakes in a lot of my games, since vanilla Civ3 to PTW 1.21f.

I'm quite certain that this is false.

Not to nitpick, but researching Printing Press is not valid proof of not having Electricity since Printing Press is an optional tech.

I think you are correct. That blob of water is really a lake and that's why the grassland can be irrigated.

I'm just about positive that PTW 1.27f did not allow irrigation through hilled cities.

Nice theory but I looked at the save with PTW and it doesn't look like a lake:

[Dominae]

It's not a lake because the tile SE of it is not a land tile.

[Jaybe]

BTW, in C3C the definitions of "lake" have changed. A "sea" tile doesn't invalidate a "lake" anymore.

[Arrian]

That is odd. Is Heliopolis definitely built on a hill (looks like it, but I'm running out of ideas here).

I was pretty sure that PTW 1.27 did not allow irrigation through hill cities, but I suppose it's possible that it got changed and I never noticed...

[bongo]

Dominae, I am pretty sure I have seen lots of irrigated tiles in funny places inside AI territory. I'm going to check a few saves before I call it a fact though..

[Arrian]

I have never seen a proven case of the AI irrigating where it shouldn't be able to. Not once.

I've seen a lot of claims that were proven false, however.

I tried to irrigate over a hill city in PTW and it didn't work. I was really suprised when it was an option to my Worker in Conquests. I don't have the latest PTW patch though so it may have been recently added via patch.

Confirmed. It is definitely on a hill. The worker cannot irrigate either North or south of that tile, It seems pretty evident that it is only being next to the city that provides the irrigation source.

Any other takers?
