Era Transition Graphics/Religions

[neutral_leader]

So, I have an idea for an extension of the Next War mod, but I need the ability to do a couple of things. I know my way around the XML pretty well, but beyond that things get fuzzy for me real quick. My needs are these:

I would like to change city art when certain religions are adopted. I know Kael does this in Fall From Heaven by assigning the religion city art to eras commensurate with those religions. I cannot, however, figure out how he set up the trigger that puts a player in that religion's era when they change state religion, or how he prevents conflicts with the normal era progression.

Secondly, I would like either a) entering certain eras to remove certain religions from all of the player's cities or b) certain religions to remove all other religions when they are spread to a city.

I'm not asking anybody to do my work for me (though I wouldn't refuse), I'd just appreciate someone pointing me in the right direction about how to implement these things. Thanks.

There is no Era progression in FfH. Era is used for Religion and nothing else (well, there are 3 defined Eras for using WorldBuilder to grant yourself techs, and presumably they would work for advanced start settings as well. But in-game you will never move from one to the next).

This is handled by a check for your religion during the start of each turn, and assigning the appropriate Era via Python calls.
