An open-source, mod-friendly Android+Desktop remake of Civ V, made with LibGDX

Last update: Jan 5, 2023

Overview

Unciv - FOSS Civ V for Android+Desktop

What is this?

An open-source, mod-friendly Android+Desktop remake of Civ V, made with LibGDX

Is this any good?

Depends what you're looking for. If you're in the market for high-res graphics, amazing soundtracks, animations etc, I highly recommend Firaxis's Civ-V-like game, "Civilization V".

If you want a small, fast, moddable, FOSS, in-depth 4X that can still run on a potato, you've come to the right place :)

What's the roadmap?

Is this order:

Polish! As you may have noticed, Unciv is fully functional but rough around the edges. This means:
- UI+UX improvements (suggestions welcome!)
- Better automation, AI etc. in-game
Finishing off Vanilla mechanics - Time Victory, Air sweep action - mostly done!
G&K mechanics - espionage, the Maya's, etc.
BNW mechanics - trade routes, world congress, etc.

FAQ

Will you implement {feature}?

If it's in the original Civ V, then yes!

There's a lot left to implement, so it's hard to give an estimation of when exactly each feature will be added, but we're constantly improving!

If not, then the feature won't be added until we've finished all the features from the original Civ - as mentioned, this will take a while!

Why not? This is its own game, why not add features that weren't in Civ V?

Having a clear vision is important for actually getting things done.

Anyone can make a suggestion. Not all are good, viable, or simple. Not many can actually implement stuff.

As an open source project, this stuff is done in our spare time, of which there isn't much.

We need a clear-cut criteria to decide what to work on and what not to work on.

Will you implement Civ VI?

Considering how long it took to get this far, no.

Is there a desktop version?

Yes! Windows and Linux versions are available at itch.io, and if you're using the Itch app, your game will stay up-to-date - and we release pretty frequently so that's an issue ;)

UnCiv can also be installed on macOS, a guide on how to do that can be found here.

If you have Java 8, and are familiar with the command line, there are (considerably smaller) JARs in Releases which you can run with java -jar Unciv.jar. For Mac users, you'll need to add extra parameters, java -XstartOnFirstThread -Djava.awt.headless=true -jar Unciv.jar.

If you use Flatpaks, there's a Flatpak by MayeulC and you can know more about it here. Flathub link is available in the Downloads section.

If you want to build it from scratch for some reason, we have instructions for that as well

How about IOS?

I'm not planning on it.

It means paying money to Apple, yet another release path, and since I don't have an IOS device it means I can't test it properly.

How can I learn to play? Where's the wiki?

All the tutorial information is available in-game at menu > civilopedia > tutorials

All the information is included in the amazing Civ V wiki

Since this is a Civ V clone, you can search Google for how to play Civ V and there are loads of answers =)

Alternatively, you could join us on Discord and ask there =D

Aren't you basically making a Civ V clone? Is that even legal?

This is a subject that I've heard a lot of hearsay on but no solid sources of law.

From what I gather, it is illegal:

To use the Civilization name
To impersonate the Civ games (so calling yourself civi|zation with a similar logo, for instance)
To use any assets from the original game (images, sound etc) - they belong to Firaxis

From what I understand, intellectual property rights apply to names, characters and settings. They do not apply to mechanics - as I'm sure you know, there are a billion Flappy Bird knockoffs

If anyone has any real legal sources, or can shed some light on the limits of what is and is not allowed, I'd be happy to hear!

Multiplayer takes advantage of Dropbox, which is non-free software, for syncing purposes.

vpn/proxy issues when creating new mp game

resolves #6709, resolves #6649 by opening a connection to dropbox when starting a new mp game

Tested on windows and linux (Zorin OS). Seems to be working now. I removed the redundant ping and replaced it with opening a connection to dropbox

I've also fixed the unnecessary commits and will close the other PR

Zone of Control

This PR implements Zone of Control (mentioned in #663), as described by https://civilization.fandom.com/wiki/Zone_of_control_(Civ5).

The normal ZoC rule is quite simple, but the exception for units that can move after attacking required an additional boolean parameter that propagates through a bunch of the movement functions.

Assign Population Improvements
Solves #6144 With a lot of help from @SomeTroglodyte

[x] Make Tile Lock matter for reassignPopulation()

[x] Reassign on new trigger at start of NextTurn. Population Growth, Improvement completed/pillaged, new Tech

Make Unassigned Population text also reassign population

[x] Add Reset Tiles button for quick tile unlocks and assignment

[x] Add Manual vs Auto Specialists functionality and controls

Auto switch to Manual when adding/removing Specialists

Click on text to toggle back to Manual. Need to work on making that clear

[x] Update Locked icon

[x] Change manual population override to Lock Tile on first click

This would match Civ5. But do people really want that?

[x] Focus Production UI and Equations (stretch goal)

[x] Avoid Growth (stretch)

[x] Translation templates

Example:

TODOS for future contributions:

Make ScrollPane to support smaller resolutions, or ExpanderTab

AI usage of Focuses

More speed improvements

JSON the weights of Stats for mod support

Great Person Focus

Translations for the mods
Resolves #2219

The changes are:

Newly generated language files contain emply lines separation between key elements (leftover from #2205 )

The language files in the mods folders are used for the translations

The TranslationFileWriter is simplified a bit: no redundant calls - no caching needed

Percentage calculation is done on-the-fly while forming the new files (instead of an extra run as it was before)

Running the app with rewriteTranslationFiles = true will also create the translation files for the mods (if any found). The additional template files can be also used, if needed.

Demanding tribute from city states

Relates to #4602. Draft for now as I'd like some feedback. This PR implements demanding tribute from city states. The formula for whether the city states go along with this is complex and some values are found in this spreadsheet. Note that this thread has some slightly different values, though that might be for BNW, or just wrong.

Demanding gold transfers gold from the city state to the demander. Demanding a worker first looks for a free worker to give to the demander, if there is none a new worker is created out of thin air.

All values are hardcoded for now.

Currently only human players are able to demand tribute, ideally I'd implement it for AI as well. Also missing is the option to denounce another player that demands tribute from a city state that you are protecting - but denouncing is currently not implemented either. I'd like some feedback on how to structure this screen to not clutter everything up. The willingness score should be displayed in the UI somewhere, possibly itemised. Perhaps another button for "stats drilldown" or similar?

Implementation of Religion - Roadmap
This issue is meant as a collection of features that religion should include once implemented. I have started working on this very large new feature, and am planning to gradually implement more parts of it over the following weeks/months.

The issues below are in the approximate order at which I'll start implementing them and includes features already implemented.

Roadmap:

[x] Great Prophet can create religions - #4505

[x] Follower beliefs - #4530

[x] May choose a different name for your religion

[x] Spreading religion with a great prophet also removes other religions somewhat or something

[x] Renaming a religion changes notifications

[x] Religious city-states

[x] Sharing a religion with a city-state decreases rate of influence decrease or something

[x] Religious wonders (Taj Mahal, Grand Temple, etc.)

[x] AI improvement so that they will choose beliefs that are directly benefiting them

[x] AI improvement so they can actually buy and use religious units

[x] AI buys religious buildings

[ ] AI for buying great persons with Faith

[x] AI chooses when to spend faith and when to save up

[x] AI for great prophets when they don't have a religion

[X] AI uses inquisiteurs to remove religions

Required policies being shown as incompatible policies in policy picker screen

Windows 10, 64 bit, and Android 12.

4.3.12 from Play Store and 4.3.14 from itch

DeCiv has a policy (Singularity) that requires three other policies and a building as prerequisites. The trouble is that the policy picker screen is saying the opposite - instead of saying that the policies have to be adopted together, it's saying "Cannot be adopted together".

The policy behaves the way it should, remaining locked until the three prerequisite policies are adopted and the required building is built. It's just the description that's got it backwards.

This PR serves as a draft, someone can copy the file, improve/correct it, and create another PR if needed, or post suggestions/corrections here directly.

Vanilla nations.json file will be added later, once final descriptions will be ready (to not have to review/modify two files).

EDIT: I made a big historical mistake in one of the description. Let's see if someone notices it ^^
