[R&F] How can I enable harvesting outside of territory for just ocean resources (or just whales)?

[Flethan]

I am trying to make a Civ that can harvest Whales outside of their territory, with either fishing boats, or preferably a military vessel. How possible is this?

You could temporarily make that plot a part of that civilization using

Map.GetPlot(x,y):SetOwner(iPlayerID, iCityID, true)

Probably you would also have to change UnitPanel.lua or some other UI Lua files to trigger the plot owner change. However, this UI trigger would only work for human players. For AI players you would have to add a different Lua script.
So I am afraid that implementing your idea is rather complicated.

Wasn't this possible with forests before it was patched out for being OP? Is it possible to put this back in that way?

Even if it was possible to set this game behavior to the pre-patch state in XML, it probably would not be possible to do this as a civilization specific trait.
