Does AI always know the location of Iron?

[Tecibbar]

In my current game, I teched Iron working with oracle just so I could grab it before Rome, only to find out Rome already settled near it. That city has no food, no water. I checked world editor. Rome doesn't even has broze working.

AIs always seem to settle on blue circles (unless racing you to a spot), so my assumption would be no - don't know for certain though. I would not put it past the AI though, those cheatin' bahstahd's.

edit: Oracling IW is a pretty bad idea

The AI knows the location of every resource in the game before researching the requisite techs.

..... in Civ3.

As far as I recall it has been proven to not be the case in 4.

Ah. They changed it, then? I always worked under the assumption that it knew. Not that it really mattered to my way of playing, mind you, but still good to know

Yes. As I, and many others, have said before the AIs in CIV have no idea where any hidden resources are until they research the required tech.

If I have time later, I'll post to link to the post 7Sins is referring to.

But they do know how much of the world you know. That's why Isabella might sell me a world map for only 5 gold, if I just bought a map revealing her empire from someone else.

I teched Iron working with oracle

terrible..... btw, iron is pretty common, it's not so strange, AI spam cities in terrible places all the times.

@jtb1127

Yup, that is ( partly ) true. By acident I browsed that part of the code yesterday , so i remember the details

Better said, the AI in that part of the code calls for the number of revealed tiles you ( or another player ) have and draws a economic value out of it ... it does not exactly what you ( or another player ) know exactly, though.

P.S Seen your sig link. I know atleast one by heart

Re. map selling the way it works is IMO perfectly realistic. Two tribal chiefs over a camp fire could fairly easily determine how much of the world each of them knew and arrive at a fair price for maps going either way. It's just quicker if the game engine does it for us

i think AIs knows all of the location of resources,they just pretend ,as they know all of the worldmap

 

[strijder20]

I think the AI is on even footing with us, otherwise the great amount of AI explorers and caravels running around the map makes no sense.

If playing on the higher difficulties, then go to aesthetics/alphabet to trade for IW. You generally don't need to self-tech IW unless you're expanding into the jungle. As many have said, oracling IW is generally not a good idea. Oracling targets can include CoL, MC, Civil Service, etc.

I really needed IW 30 turns before everyone else. I started in Siberia, and the grass were just greener in their land. As August settled near the only iron around, all military resource are like 10 roads away, deep into the barbarian territor.

I should see that coming when my starting points has gold, silver, and 2 wheet.

Wait, you have 2 food and 2 major commerce sources and you are not happy???

You're upset about starting gold? After mining that 7 is a huge bonus to .

Phew - lots of misinformation in this thread, let's see if I can clear it up.

Civ4's AI does not know the location of hidden resources, nor does it see the full map (as has been claimed here). We tested this right after release because these rather obvious AI cheats were a big issue for many of us with the Civ3 AI - it was quite aggravating to see the Civ3 AI settle in the middle of the desert because it knew there would be oil later, and it was quite hilarious to exploit the Civ3 AI's knowledge of the map by "channeling" its attack forces into endless loops. We were pretty glad when we saw that these issues did not happen with the Civ4 AI.

We did some (imho) pretty solid tests on alleged AI cheats in this thread. Note that at first we actually found out that the AI _did_ "see" hidden resources under certain conditions (which were unlikely to happen in a real game), but that was a bug, which Soren promptly fixed.

Side note: No offense, but I really wonder why people keep making obviously false claims without testing them. I mean, I would feel pretty bad if I stated something like "The AI sees / doesn't see the resources" as a fact without either checking it myself before, or making sure that the claim is based on a reliable source. Checking it by oneself is quite easy to do with the worldbuilder.

In case you wonder why I'm addressing this: I believe that such false statements about the AI are one of the reasons why Civ5 has such an abysmal AI. You can listen to Sid Meier talking about game AI in his GDC 2010 keynote address, he says that an AI must not be too clever because the player will just say that it cheats. (Source: here). Civ4 has a pretty good AI that removed many cheats that the Civ3 AI still had - but people are still just saying that it cheats when it does something well. The logical conclusion for game developers is that it doesn't pay to develop a very good AI because lots of players will simply refuse to acknowledge it. Therefore it's much more cost efficient to develop a game with a weak AI -> see Civ5.

So, next time you state as a fact that the Civ4 AI is cheating with something, do actually test that, okay?

How much have you been paid by Firaxis, you obedient instrument of pro-Firaxis propaganda?! It's the duty of every independent thinker on the planet to denounce the secret manipulation of Firaxis and their brainwashed sheeple! The Firaxis Conspiracy has its agents in every government in the world, and they wouldn't hesitate to bribe these governments, so that they would spread disinformation about the lying, cheating, dirty Civ4.

You obviously haven't read my rants about Civ5.

The AI does get to see everything in the squares it can move to, right? Which means for late game naval units, they have a sight range of about 5+?
