Cause of plague

[TruePurple]

Is the odds of a plague event caused or increased by-
Placing the town on floodplains?
Working jungle/floodplain squares?
Your town being close to floodplain/jungle squares? If so how close?

If its caused by working or being close to plague causing terrain, does working more such tiles or being closer to more such tiles make plague more likely? Would someone please explain how plague works

I think you are talking about disease not plague, plague is only enabled in some Conquests unless you enable it with the editor.

I think disease only depends on the number of flood plains worked. I do not think the base square counts (not sure). If a city is struck with disease it will automatically be diseased the following turn as well (unless already reduced to size 1), this happens even if no flood plains are worked.

Units fortified in jungle may also randomly be struck by disease so sentry such units instead.

Could have sworn I got a message about a plague hitting one of my cities in a random conquest game. You sound uncertain about your information, is there someone who knows for sure?

As you can see the permit plague is not checked off in the random conquest game.

You sound uncertain about your information,(not related to the plague verses disease issue) is there someone who knows for sure?

There is no plague causing terrain, it is a random event, the same way volcanos are random events.

Terrain can cause desease which will cause decrease in population, but will not cause plague. Plague causes units to be killed, where desease will not harm units.

Enough about plague please. My questions were, how does terrain cause disease. -insert first post with the words disease instead of plague-

If you are talking disease, bingen answered your question in post #2.

...and, the city center does count IMHO.

 

[TruePurple]

No bingen, told me how he thinks it might work. He did not sound certain at all.

It has been determined that just the presence of disease causing terrain within the city radius will put that city/town at risk. It use to be thought that citizens had to be working the tiles. I have no idea where the thread is that showed this.

Discovery of Sanitation will stop disease from floodplains but not jungle.

It appears (from much play time) that the initial risk of disease striking is extremely low... possible around 1% or maybe less. Once disease has struck, the odds of it striking in subsequent turns is much increased for an unknown # of turns.

Hope that helps.

City radius- all possible to work terrain tiles for that city? Does it include tiles outside your domain but inside what will become your city radius?

Does more tiles of those two types inside your city area increase your risk of disease? By how much for each tile, do you know? Does the tile the city sits on count for causing disease, or even count extra?(meaning more odds if the city is sitting on it verses just being in city radius?)

Does closeness of these tile types increase your likeliness of disease? Like is jungle right next to a city more likely to cause disease then jungle two squares away?

If tiles just within your city limits cause disease, does working them increase your chance of disease?

I don't think anyone knows the answers to your questions. Except maybe the first. City raidii is accepted to be the radius that has workable tiles at the moment.

Inferences may be made by the notification that comes up. 'NEARBY jungle/floodplains is causing disease in such&such city.

Disease is almost impossible for the mathmatically inclined to set up a test for and derive the formula. Thus, AFAIK, it has never been done. Plus i don't think the programmers ever enlightened us as to the chances.

I've gone many a game without ever getting any disease. Other games have had a lot of it. It's all up to the RNG. The benefits of floodplains far out weigh the small chance of losing population. Jungle turns into nice grassland once it is cleared. It just sucks having alot of jungle early in the game.

This might be true, but actually working the tiles seem to increase the chances. One can test this by reloading to the turn before disease struck and rearranging the working of tiles, this will sometimes prevent disease from happening.

By constantly reloading and replaying the same interturn (with preserve random seed OFF) and varying the worked tiles it ought to be possible to statistically discover the formula. If the formula is complicated one might need very many iterations though.
