[Lua] Interesting Finding: GameEvents.CityCanCreate

[Androrc the Orc]

After trying around a bit, I've found out that it is possible to affect the conditions to create projects in a city, by accessing GameEvents.CityCanCreate in Lua. This is a very simple example:

function CanCreate(iPlayer, iCity, iProject)
	local player = Players[iPlayer]
	local project = GameInfo.Projects[iProject]

	if (iProject == GameInfo.Projects["PROJECT_NEW_IDEA"].ID) then
		return false
	end

	return true --need this for everyone else
end
GameEvents.CityCanCreate.Add(CanCreate)

This will naturally block PROJECT_NEW_IDEA from being created in a city. Of course though, this is just a demonstrative example, the game event can be accessed to include conditions as desired.

Very interesting

Too bad that (at least as far as I know) there is no comprehensive, complete list of GameEvents.
