Terrain Improvements costing gold

[Hammurabi II]

Does anyone know if there is a mod that allows you to apply a cost to certain terrain improvements? Just for an example, to build a cottage could cost 5 gold, or a mine 10 gold, etc. If not, would it be hard to create such a mod? Thanks!

I don't know of a way to do it from editing XML only, as neither ImprovementsInfos not MissionInfos do have relevant tags.

You will need to work with Python. There are a onImprovementBuilt() and onUnitBuildImprovement() entry points from the EventManager - should be easy to hook in there, check what improvement was built and substract the gold (or perhaps deny building if there is not enought money).

Watch out tho - unless you are planning to rebalance the whole economic systen - those numbers you talking about could have quite a big impact i.e. on the early game.
