By the way, how's going with those old theme about special buttons for run/strafe/n.vision?
Post by: Meridian on September 21, 2018, 04:31:34 pm
It's still high on my todo list.
Post by: Alphyn on September 21, 2018, 05:54:53 pm
I've tried playing OXCE on Android and the combat controls feel really odd and unpredictable. In odrer to make a soldier go to a certain tile you need to click the tile directly over the tile you want him to go. To confirm movement, you need to tap the top of the cursor cage. If you tap the bottom of the cage where the actual tile is and where the circle with an X that shows the remaining TUs is, you will select the tile under it.
This is even more noticeable when controlling a tank. Intuitively, you need to tap the intersection of the four tiles you want the tank to occupy. Te results of this are unpredictable. What you actually need to do is to tap the tile which is over the northern tile of the 4 tiles you want the tank to go to.
It looks like this behavior is inherited from the desktop version. But it isn't a problem on desktop because you can see the cursor cage all the time as you hover the mouse cursor over the battlescape. But you can't hover on Android. If you tap and drag you scroll map instead, so more precision is required for the mobile controls.
This issue results in a lot of annoying misclicks. It's especially bad when you want to select the tile to the north of the currently selected and you tap the top of the cursor and accidentally confirm the movement.
Is there anything that can be done about this?
Post by: Meridian on September 21, 2018, 06:06:05 pm
Can some regular Android user confirm that it feels like this and it's not just Alphyn's issue? @Yataka? @Nord?
As for a fix for this:
1/ I don't know what kind of options are available... any ideas/suggestions?
2/ I am not really an Android developer, I just took the Android support from OpenXcom and merged it into OXCE... maybe @sfalexrog could help? He did the OpenXcom for Android port.
Post by: Nord on September 22, 2018, 08:53:55 am
It is so for pc version, but there you see a "cage" when move your mouse.
To fix this problem you need only to turn on a option "confirm moves" (or something like that) to tap screen twice to make unit go.

Main feature for mods is lazy-loading extraSprites... which should drastically decrease memory (RAM) requirements and significantly improve startup time.

Tried this version as well and found one problem. Search on the Tech Tree Screen is broken. Entering three symbols or complete titles of the topics available to research doesn't solve the issue regardless of the case. Ufopedia search works like a charm, though.

After installation and launch, the background music in the game began to sound much quieter. At the same time, all other sounds (button presses, shots, screams) remained at the same level. This is observed both in the vanilla version and with the FMP mod.
The problem is not very significant, after I increased the volume of the music in the settings from about 40% to 100%, the music began to sound something like in older versions of the game. But I wonder, this is how it works only for me or for everyone who plays on Android?
Post by: Meridian on January 25, 2019, 11:13:17 pm
there is a new version: https://lxnt.wtf/oxem/builds//Extended/Extended-5.2-ef6401a-2019-01-23-android.apk
with a lot of engine changes.
I'd like to ask for help with testing... to begin with, just try installing and running the new version and let me know if it runs fine on your device...
Thanks for all the help.

I'd like to ask for help with testing... to begin with, just try installing and running the new version and let me know if it runs fine on your device...On my Android 6.0 with 1 gigabyte of RAM, this version works well. I did not play a lot, but I ran several mods, including X-Files and X-Piratez, packed in zip-archives, there were no failures.
Thanks for all the help.
Of the features of the work, I can only indicate increased RAM consumption. When playing in X-Piratez, other applications running in the background are unloaded. Perhaps this is due to unpacking the mod. On older OXCE for Android, with X-Piratez not packed in the archive, this did not happen. But maybe there were some other reasons.
I also post OXCE for Android on the Russian-language forum for those who are uncomfortable to follow the updates here. I reported about this version as soon as it appeared, gave a link to the repository with it (and tried it myself at the same time). And when the link to download was changed here, I posted the apk-file itself, with a description of its capabilities. The file was downloaded 13 times (and someone could have previously downloaded from the repository), but so far there have been no reports of incorrect work.

I'd expect some small increase in RAM consumption with the ziploader since it keeps zip directories and decompression contexts of all zips, plus the list of what file is where became more verbose. But I would not expect this to be significant. This I'll be looking into.
On a general note, 1Gb RAM is not really sufficient for Piratez. Also beware that since the lazy resource loading upgrade last year RAM usage grows with use, so it not being killed on startup means not much.

You probably see Adlib only because the game didn't find/recognize any music at all and defaulted to this option.

I looked into the files you sent me, the gold edition has only MIDI music files... which don't work on Android atm... we'll be looking into that.don't worry about android midi support. it'll need timidity at least to make it sound plausible, but eats resources like hell. my tablet goes through it's charge like a wolf through a young rabbit while playing the current version.

the adlib.cat attachment is for xcom-eu, using it with tftd plays the intercept music at the menu, which is cool btw. ;)
so, in short, adlib works perfectly.

When trying to upgrade from OpenXcom Extended 5.3 (v2019-03-05) to the latest (Extended-5.3.2-78915c2-2019-03-25-android.apk) it fails.
From Logcat output I found this line:
PackageManager: Package org.libsdl.openxcom signatures do not match previously installed version; ignoring!

Seems I misunderstood the changelog, or rather I didn't review the OXCE xcom1 files -- the Skyranger and Interceptor will always show up by default because they have the forceShowInMonthlyCosts attribute set to true. I was playing Reaver's megamod on PC and noticed that one of the mod crafts no longer showed up in the monthly costs page and attempted to reproduce it on Android by getting rid of my Interceptors.

Is it possible that changing the game files directory to one I created on removable storage is causing problems? When I open the app, it takes me to the setup screen and shows that both UFO and TFTD are there, status is green, but when I save and restart it just takes me back to the setup screen. The log shows:
[INFO] Loading rulesets...
[FATAL] FileRecord::at(GEODATA/PALETTES.DAT): requested file not found.
[ERROR] FileRecord::at(GEODATA/PALETTES.DAT): requested file not found.
[INFO] Found candidate method ID: 0x7f71b2v0f8
[INFO] Returned to native code!
I've verified that the file exists in both UFO and TFTD directories.
I prefer to keep as much non-critical data as possible on SD card, so I changed the 'Path to game data files:' setting to my SD card, placed the game files in the folders, and OXCE seems to recognize that they're there - it seems it just fails to actually load them.

If I leave everything as default and use the setup screen to copy the files from the directory I was previously trying to use, it works fine. It definitely seems to be a problem with selecting a different directory as the game files directory.
I don't know how that part works, never used it actually.
I'll try to have a look at it eventually, but right now I'm not in a mood to install Android Studio.
If someone wants to help, it would be most welcome...

Thank you again for Android OXCE adaptation. You do a great job. People from russian mobile community are really excited with it.
Only thing they asked - what about your plans of additional screen buttons?
Thank you again.

Hi, Meridian.

Thank you again.
I'm postponing it each time I see it, because it's not the easiest nor the most interesting task to work on.
Maybe I can work on some "quick win" smaller features during Xmas... but no promises.

Does this have external sd card support (via the storage access framework) and if not would it be possible to add it to the next version?
Sorry, we're not exactly Android devs here.
Can you please write why is this needed, what problems does it solve, wtf is storage access framework and how you see it working?
