Event that triggers when an improvement is contructed; how to reveal a resource

[PawelS]

I'm going to make some types of great people able to discover new resources by constructing a temporary improvement with good yields (so the AI will do it), immediately after constructing this improvement should disappear and create a resource on the tile. I think I can handle the code that removes the improvement and places the resource, but I need help with 2 things:

1. How to make an event trigger when a specific improvement is created?
2. In case the hex where the improvement is constructed already contains a resource, undiscovered due to not having the needed technology, the resource should be revealed instead of creating a new one (like it's done with an unused goody hut effect). Is it possible to do it with Lua, and if so, how?

The standard event which triggers for the completion of an improvement is particularly useless as it only fires if the hex is visible to the human player

So I guess doing it properly will require DLL changes. Theoretically it can be done by scanning the entire map with Lua every turn, but this can have a negative effect on performance...

Depends on the size of the map And if the improvements can only be built on certain terrain, you can cache the possible tiles on the first full pass.

You mean it's in your version of the DLL? I can't see it in the description on your site...
