Implemented an automatic update mechanism for DF Remote server. Now the dfhack plugin needs to be installed only once, and the update procedure when a new version of the client application is released is greatly simplified.

Updates are cryptographically signed and this functionality can be disabled.

Good news - I finally have added a save button (quicksave), save and close button (like the normal DF save), and a disconnect button. Bad news - save and close doesn’t work on Windows for some reason. At least everything else seem to work, otherwise it would have been be a bad surprise. EDIT: Fixed, no bad news for today.

Implemented a simple NAT traversal mechanism

More people should now be able to connect to their DF game running at home. 

Also, shaking your device will now show a popup with a page from relevant to the current screen. This will change in future though – I don’t like using shake for any actions, and ideally it should be possible to show help for example for individual jobs in a workshop and not just for the entire screen.


Dwarf Fortress Remote status update

Over the weekend, I implemented a lot of missing functionality, mostly related to building and buildings. Almost all buildings have their actions and options available at build time implemented now. Also improved handling of announcements, specifically popup announcements, and other UI elements. Reconnection / restoration of game state is much faster now even if the app has been terminated while in background.

I do not answer questions about the estimated release date, mostly because I do not know how much time I’ll have to work on this. Below is the list of unimplemented stuff.

Missing: military screen (while squads menu is implemented), workshop profiles, stockpile-workshop links, health overview screen, justice-related stuff, stocks screen, civilizations screen, points/routes/notes, burrows, hauling, traps/levers and their linkage, world creation/starting a new game, several building actions (e.g. assigning creatures to cages and chains), nobles requirements/demands/mandates.

It’s a huge list, and some things are really important and I will work on them now, while some are deliberately skipped and will not be done until after the first public test release. Of course, advanced players may consider all of them must-have, but technically you can play without burrows and minecarts, for example.

I’m mostly happy with the networking and UI code, so can focus on this list now. The only other non-gameplay thing I’ll do is a support for NAT traversal, so that more people will be able to connect to their game running on a computer at home.

Spent last couple days playing Dwarf Fortress on the go (too bad there’s no save button yet). This resulted in fixing some crashes, making UI/UX improvements related to repeating operations like placing buildings, and also dramatically improving network performance and responsiveness. Here’s a video demonstrating gameplay over a 3G cellular connection to a server in another country (175ms ping). Actually, it’s a bit smoother in real life then on a recording.

I’m now finishing this stuff, then will be another round of implementing missing screens and functionality, and then I’ll prepare an alpha version to give out to number of people to try.

Experimenting with UI colours again

June 5, 2015
Dark background is required to be able to use standard DF colours for professions, jobs, materials and everything else, but initially I was going to use all the default colours for UI components. Probably only some screens will be dark, and some will be partly dark, as the item and unit info screens.

Also making row height smaller on certain screens either as an optional compact mode, or more likely not optional, because it’s much less comfortable to navigate long lists (units, trade goods) when only several items fit on screen, compared to one text line per item in DF on desktop.

Artifact list, item info screen, look mode, look list, container contents view. Look mode eventually will replace building query mode and unit selection modes because there’s no sidebar on mobile so no real differences between them anyway.

Overcoming 16-colour palette limitations in Dwarf Fortress

May 19, 2015
In Text Will Be Text version 5.46 I’ve added a way to use colour values from colour tokens for tiles. If any background or foreground colour is >= 100, then colour values will be taken from[value-100]. One example of how to use this is the included script realcolors.lua, which processes material definitions and replaces tile colours with values from material.state_color.Solid, which will give results similar to the screenshots below.

Before: After (note the different colours of wooden furniture): Technically this was very easy to do but some work probably will be required from tileset authors. Some colours specified in vanilla raws are not quite correct, but this can be fixed (e.g. by using an external colour database, one option is to use Stonesense data, as Japa suggested). The biggest problem here is that tilesets are designed to make use of background and foreground colours, while if we make use of colour tokens, there will be only one foreground colour. For the background colour, we’ll have to either leave it as is, or set to some fixed value (e.g. black or white), and that’s not what existing tilesets expect. EDIT: On the other hand, if you specify colours manually (in raws or overrides.txt for overrides), you can still have both foreground and background colours set to anything you want.

Here are some details on feedback to user actions and on behaviour in case of network issues.

The problem. There are basically three types of actions. Some you want to perform/queue quickly, e.g. marking many items for sale. You still want some feedback, but it shouldn’t prevent you from performing further actions. Some, on the other hand, should block the UI until they are executed and response received, e.g. actually selling items. Also, map-related actions do not require any feedback - when you change z-level you naturally wait for the screen to update.

I wanted the user experience to be smooth in case of possible frequent disconnections, either because of network problems, or because of switching to other apps, locking the phone, etc. So the reconnection must be quick and shouldn’t involve reloading more of the game state than required. At the same time, the game state must be always synchronised between the server and the app - if you issued a command to sell items, then disconnected and reconnected, you should see the result, and the command must not be sent/executed again.

The solution. The app and the server now maintain a queue of undelivered commands and responses that is preserved between connections to the same game. This means that no use action can ever fail because of a network problem - the app will try to reconnect until it succeeds and sends/receives all queued commands and responses, or until you cancel. You do not need to retry any actions manually. Implementation of game screens became easier too, there’s no need for any screen-specific actions to handle network problems and/or to synchronise the state after reconnection.

The video at the top shows how it all works from the user’s point of view. Timeouts are deliberately inserted in the server code, and also the same command was used to demonstrate both non-blocking and blocking behaviour. There’s a small set of commands that are transmitted separately and not handled by this mechanism, mostly related to map movement and updates.
