Modding requests

[yairm210]

There have been a lot of various requests to extend the modding in various ways.
Usually they're from one person, and have very little effect on the general playerbase, and they're kind of clogging up the issues.

So this is an issue to consolidate all those requests, as comments to this issue.

1. Making roads and railroads modifyable - currently, these seem hardcoded. Putting their parameters in TileResources.json and allowing Unciv to handle modded roads and railroads would be extremely beneficial for, say, a mod with several kinds of roads.

When described in the json, roads and railroads could have parameters like "Double movement rate" and "Triple movement rate upon researching [ ]". There's lots of opportunity here.

2. Allowing terrain-tied resources - currently, resources stay the same if a terrain feature (most commonly Forest and Jungle) is removed. I'd like it if it were possible to set a (in TileResources.json) a resource such that it disappears if the terrain feature it occurs on is removed. Admittedly, this is not present in Civ 5 itself, but it would be extremely helpful to modders like me in putting resources like Cedarwood: I mean, you can't get cedarwood from a tile you've deforested, after all!

A unique for this, maybe "Is removed by [Remove Forest]".

3. Selective improvement construction: currently, the Roman Legion has the "Can construct roads" unique. It would be great if this unique could be generalised so that it works with any improvement: not only would it make it easy to add the Legion's other ability of constructing forts, it would also be extremely fruitful for modders.

"Can construct [Road], [Fort]".

4. Tile improvements unique to units: I'd like to be able to define a modded tile improvement as being unique to a non-Worker unit, so that the Worker can't build it.

Maybe a "UniquetoUnit" parameter inside the "uniques": in TileImprovents.json or something similar? This would also allow Oil Wells to be restricted to Workers and Offshore Platforms to be restricted to Work Boats, as in Civ 5, assuming that the "improvement": parameter in TileResources.json can handle more than one improvement.

4. Allow terrains, terrain features and resources to be restricted to spawn only on River tiles.

A unique to the effect of "Must be on [River]" or something similar would be great, especially for futureproofing Unciv for Civ 6 (if you eber get to that), and also for modding.

Here are some ideas for uniques.

"Can not be sold" - for buildings.

"Unlocks at [Era name]" - for buildings and units and improvements (already implemented for Policies).

"Food required for population growth +/- [x]%" - as nation and policy unique (also called civ-wide).

[ravignir]

Just a clarification of what i've meant with the last idea.

A way to interact with this parameter. Maybe call it "City growth rate +/-[value]%"

[ravignir]

Another suggestions;
Modding unique that makes other policy trees non pickable:
i.e If i pick Piety, I can't pick Rationalism and vice versa;

"Unlocks at [era]" unique for buildings, units;

[Caballero-Arepa]

This is already mentioned on the first comment but: A unique that allows units to build specific tile improvements, like "Can construct [Fort]".
Currently there is only: "can build improvements on tiles" and " Can construct Roads".
