Description of your issue

Evoland is an Adobe AIR based game on Steam. It's basically just an SWF file that can be played with flashplayer, even though the file extension is actually .dat. It has both a Windows and a Linux version (the Linux version is not advertised on the Steam page but exists), but the SWF files are not the same. The Windows version shows the developer logo, but once it fades out, the screen stays black and Lightspark just hangs and only prints INFO: FPS: XX Y to the terminal when I Alt+Tab. The Linux version crashes immediately.

~~For some reason I could not redirect the terminal output into a file so I have only the last 10k lines copied from the terminal~~
Nevermind. Here are the full logs:
With SWF from windows version: log_winswf.zip
With SWF from Linux version: log_linuxswf.zip

The text was updated successfully, but these errors were encountered:

For me, on latest git master (a75a5d8), it segfaults. This is with the Linux version.

Here is a backtrace

I've committed a fix that should fix the crash, so please test it.

The behavior for the Windows version of the game hasn't changed, the Linux version no longer crashes but it doesn't work either:

huwdp · 2021-11-07T23:21:05Z

Lightspark does not support MessageChannel as can be seen here (search for MessageChannel). Shumway stubbed it (https://github.com/mozilla/shumway/blob/master/src/flash/system/MessageChannel.ts).

dbluelle · 2021-11-08T13:23:18Z

Yeah, implementing the MessageChannel class is difficault without any example swf that uses that class.

huwdp · 2021-11-08T22:11:43Z

I've created an example here using code from https://github.com/probertson/as3-workers-examples. It works on my machine using the official Flash player.

dbluelle · 2021-12-02T18:53:25Z

I've implemented the MessageChannel class and the example works (except for the background color of the textfield, but that is a separate problem...)

Firlaev-Hans · 2021-12-02T19:11:43Z

The game still doesn't work. The Windows version still hangs after the logo at a black screen, and the Linux version immediately shows a "yet unsupported Flash file" error with the following terminal output:

I'm sorry but in this case I don't think I can do anything without the swf file...

Thank you so much! :)

I have purchased the game on Steam.

@Firlaev-Hans Do I have permission to send the game files privately to @dbluelle? I will send it to @dbluelle's commit email, as a link to a google drive upload. Then when @dbluelle has downloaded it, I will delete it from google drive.

I've got the game files from @eiglow and committed some fixes for lightspark so that it basically works now.
The only thing still missing are the music and sound effects.

I can confirm that the game is now playable (the Linux version anyways, the Windows version still hangs). But besides the missing audio, the color palette is wrong:

Anyways, thanks for your work!

huwdp · 2021-12-04T18:25:24Z

This is cool!

huwdp · 2021-12-04T18:33:28Z

The colour difference is probably just a RGBA and BGRA issue where the red and blue get mixed up

dbluelle · 2021-12-04T18:43:44Z

The colour difference is probably just a RGBA and BGRA issue where the red and blue get mixed up

Yeah, looks like it. The game uses Stage3D for rendering which is implemented but not much tested...

Firlaev-Hans · 2021-12-04T21:05:57Z

I did some more testing:

Once you get to the part where you unlock monsters (about just one minute into the game) performance drops significantly (30FPS instead of 60). In general performance is suboptimal and one CPU core is always utilized 100% almost all the time, and RAM usage continuously climbs as you play
The overworld (maybe 3-5 minutes into the game) looks incorrect, as there is a white grid pattern, plus the textures are not supposed to be blurred / filtered:
The game crashed when I tried to eat the weird magical seed inside the well in the village that is supposed to turn me into an adult. This part is approximately 10 minutes into the game so I didn't try it again because:
Save points don't work. The game will pretend that it was saved but once you restart the game or return to the main menu, "continue" is still greyed out. I assume Lightspark doesn't handle saving like this at all yet? Without saving it won't be fun to debug a game that takes 4 hours to complete.

dbluelle · 2021-12-09T18:25:04Z

Regarding the savepoints:
By default Lightspark doesn't allow local storage, it has to be explicitly enabled in the settings menu (right mouse click->settings).
This is how Adobe handled that in the browser plugin.
Maybe we should always allow local storage when starting from command line or at least add a command line parameter to enable that.

Firlaev-Hans · 2021-12-09T18:55:38Z

Regarding the savepoints: By default Lightspark doesn't allow local storage, it has to be explicitly enabled in the settings menu (right mouse click->settings).

Even with local storage enabled save points don't seem to work ("Continue" is still greyed out in the main menu).

On a different note, I just played until the part where the game previously crashed once again, this time it didn't crash when I ate the weird seed. However, I got another "unsupported Flash file" error when I wanted to sleep at the Inn in the village:

dbluelle · 2021-12-10T19:25:21Z

Savepoints are now working (if you enable local storage in the settings)

dbluelle · 2021-12-11T16:23:50Z

The RGBA-BGRA issues should now be fixed, maybe also the other graphical issue and the "Property createRectangleTexture not found on flash.display3D::Context3D" error.

Firlaev-Hans · 2021-12-11T17:28:23Z

The RGBA-BGRA issues should now be fixed, maybe also the other graphical issue and the "Property createRectangleTexture not found on flash.display3D::Context3D" error.

Yes, all of those three issues are fixed.

The sound+music is still completely absent, and performance is sub-optimal (seemingly due to being single-threaded?). Some loading times / transitions are kind of long too. And there are also some (not easily reproducible) crashes here and there but with save points working that's not such a big deal. The beginning of the game is completely playable now.

HOWEVER: The biggest problem is the continuously climbing memory usage. There must be some memory leak, because after just a few minutes of playing I had to kill Lightspark as it was using over 11GiB (out of my 16 gigs) of memory.

AND: After playing for about 20-30 minutes, there's a boss fight after which game is supposed to become 3D. (If it wasn't obvious, this game shows the development of RPGs so it gets more technically advanced as you play)
As I sort of suspected, this does not appear to work in Lightspark, as the window froze when the 2D to 3D transition was supposed to occur. Or maybe it would have worked after waiting some more, but due to the memory leak I could not afford to wait that long.

Here's a save state of just before that point.
You'll have to extract it to the respective folder in ~/.cache/lightspark/data (on Linux anyways). To get to the 3D transition, you will still have to walk to the right and up and then fight the boss in a turn based battle (initiated by walking up to the crystal and pressing space)

dbluelle · 2021-12-11T18:54:12Z

I suspect that the sound issue is somewhat connected to the memory usage.
In this game the sound is computed in a background worker thread which run's all the time, even if no sound is played (it generates silent samples in that case). I have to investigate further...

dbluelle · 2021-12-30T17:29:29Z

Ok, I've fixed some stuff, so this is the current state:

The sound now works to some extend, but it's not perfect yet.
The switch to 3d works, but there is a graphical glitch in the 3d world (the main character has no face...).
performance should be better, but not as good as Adobe
local storage is now stored in the same format as adobe does, so savegames from Adobe can be used in lightspark and vice versa. Unfortunately this means *.sol files from older lightspark versions don't work anymore. I've attached the savegame from above in the new format: savegame.zip

Firlaev-Hans · 2021-12-30T18:59:48Z

For some reason that isn't the current state for me. With the latest commits I currently get "Unsupported Flash file" again on launch:

I couldn't reproduce the exception in a reliable way, but I've committed something that should fix this.
Also there are more fixes for sound handling and local storage is now always enabled when using the standalone executable.

Firlaev-Hans · 2022-01-01T20:34:08Z

Yup, thanks! The game now runs again and, up to the 3D part, works quite well! However there were still some slight issues which I have compiled in a little video (forgive the horrible bitrate, I wanted to keep the file size small)

LightsparkEvoland.mp4

The color issue came back temporarily after loading a save game
The music often starts playing / changing with a delay, but most other sounds play fine and at the correct time now
The transition between the world map and the... normal world looks a bit weird
The screen randomly flickers white sometimes
Some transitions (like entering houses) lag for a second but it's tolerable. Performance and loading times in general are way better than they used to be and totally fine to me
As you already noted many 3D models render incorrectly (Z-Buffer glitches / surfaces get rendered in front of other surfaces when they should be rendered behind them)
When I opened the chest with the heart just after the 3D transition, the game froze, well, at least the graphics did. I could still hear me swinging the sword when pressing space. This is consistently reproducible for me.
Lightspark still got up to around 2.5 GiB of memory usage after playing from the beginning to the 3D part in one go. A bit on the high side, but definitely better than before.

dbluelle · 2022-01-02T16:21:02Z

I've fixed the game freezing after opening the chest with the heart.

Firlaev-Hans · 2022-01-03T20:36:06Z

Another crash (stack overflow) when opening the chest on the world map that, I think, would make the map 3D:

dbluelle · 2022-01-05T17:49:15Z

I've fixed the stack overflow crash.
I'm still trying to figure out the glitches when rendering the 3d models...

Firlaev-Hans · 2022-01-05T20:35:41Z

I'm happy to report that, graphical/sound glitches and occasional hangs / crashes aside, the game now appears to be fully completable! I say "appears to be" because I haven't actually beaten the final boss yet, because it turns out that beating him while almost everything is invisible is a little hard... Let's say, the Z-Buffer glitch that we previously encountered isn't the only 3D rendering issue.
EDIT: I now managed to defeat the final boss and watch the credits sequence, so now I can definitively say that the game can be completed in Lightspark even if the graphical glitches make some parts harder than they ought to be.

So here are some more issues, each with screenshots and savegames:

What it should look like:

In turn-based battles on the 3D Overworld, the ground isn't rendered / is completely black. Maybe this is also simply caused by the Z-Buffer issues that you're looking into right now, but it doesn't really look like it to me. Also, the background is affected by another RGBA-BGRA issue.
What's even more annoying, is that the audio pops a lot during the battle.
Here's a savegame. Leave Aogai City by going down, then in the Overworld walk around on the grass until a battle starts.

This Diablo-esque part is almost unrecognizable:

It looks like the floor texture is stretched and has an RGBA-BGRA issue again, while the rock texture is just black.
EDIT: This behavior has changed now: No color issues, and the rock wall texture is now rendered (but stretched), ~~instead it's now the floor that is entirely black.~~ but blood stains on the ground are black.
What it should look like:

Also the performance drops quite a bit while fighting lots of monsters at once here, and during the boss fight, the audio popping returns.
Savegame - Go south east until you encounter a chest, opening it summons the boss.

The first encounter with the final boss suffers from black or missing objects:

At least in this case it doesn't really have an impact on gameplay, since this is a turn based battle.
Savegame - You will have to go far to the east over the bridge to the tower, and you may or may not get annoying random encounter battles in between...

During real the final boss fight it's even worse, and does impact gameplay

You can't see the stage at all and sometimes the boss is completely black too. This fight isn't a turn based battle, you have to see where you're going, so that's a problem. The first phase of the boss is sort of manageable but I didn't manage to defeat the boss this way.
Savegame - Simply walk to the mana tree (but don't enter the air ship)

But on a different note, I'd like to praise the recent performance improvements! I got the game to run in Lightspark on a RockPro64, an ARM based computer barely more powerful than a Raspberry Pi 4, and even after unlocking HD textures the game still ran semi-smoothly! (didn't test the obviously more demanding Diablo part yet though)
Thanks for your hard work, @dbluelle ;)

dbluelle · 2022-01-15T17:26:27Z

I've managed to get the windows version of the swf file running (at least on Linux ;) ) with the following limitations:

has to be run with --air.
it tries to start a native process "GetAch.exe", which does not yet work. The neccessary AIR classes "flash.desktop.NativeProcess" and "flash.desktop.NativeProcessStartupInfo" are only implemented as stubs but don't do anything.
unfortunately the save games are not compatible to the linux version, so I couldn't yet check if the 3d stuff has the same glitches in both version (It would be nice to know that to further debug the glitches...).

Firlaev-Hans · 2022-01-15T18:55:56Z

I replayed the beginning of the game with the windows SWF and found surprisingly many differences to the Linux version so far:

Some of the Linux versions minor bugs such as the music delays, the delays / lags when entering buildings, opening certain chests etc., the rough looking "Mode 7 Overworld" to village transition and probably others are NOT present using the Windows version
The font used in the main menu and some other places looks... weird. It's supposed to look the same as in the Linux version but it actually looks kind of jagged
When you load the savegame called "256colorsavebug" (see the bottom of this post) and you go to the left to and
unlock 256 colors, then return to the main menu (with Esc or by getting killed, but don't restart lightspark) and reload the savegame (where the game was still in 16 colors), some tiles are completely black
chests on the 2d world map are blurred / filtered (load "leavingPapunika", go to the far right and up to leave the village, then you'll see one)
When you load "InnSave", enter the inn, talk to the innkeeper and choose to sleep, suddenly only the bottom left of the screen will continue to be updated while the rest shows the last frame and flickers until you restart Lightspark
The 3D transition crashes Lightspark. "pre3dboss" is once again a savegame just before the boss fight leading to the 3D transition. Here's a -l 4 log.
Another thing I just noticed when I loaded up that savegame in the actual windows version in Wine, is the fog in the cave. It should look like this:

But in Lightspark it looks like this, not terrible but not quite right either:

Interestingly, the Linux version of the game doesn't have this fog at all (and I don't mean in Lightspark, it just doesn't have it even in the original version)

Here are the mentioned savegames: sharedObjects.tar.gz

dbluelle · 2022-01-15T19:21:18Z

Yeah, the versions are handling the resources (images, fonts and sounds) differently.
The windows version uses standard flash resources for all this, but the linux version has some kind of "virtual filesystem" added, so that all resources are just some binary tags in the swf.
Also the windows version is heavily obfuscated, so it's really hard to look through the actionscript code...
That's why I like to have a comparison of the 3d stuff, to exclude that this "virtual filesystem" code triggers any bugs on lightspark.

dbluelle · 2022-01-16T15:01:02Z

The crash when transitioning to 3d is now fixed. The 3d models of the player, the monsters and the boxes look "interesting"...
Edit:
I've fixed the textures on the 3d models, so they now look more or less the same as in the linux version. That means the "virtual filesystem" is working correctly and is not the reason for the broken 3d models.

Firlaev-Hans · 2022-01-16T17:47:56Z

Sweet, the 3D crash seems to have been the only thing blocking a full playthrough this time. Although I get an error message when trying to quit the game from the main menu:

Also there are memory leaks again. It seems like, whenever a 3D scenery is loaded memory usage increases, like, it doesn't remove the previously loaded data from memory or whatever. You can see this while walking between the different screens in Aogai village, or every time you switch from 2D to 3D with a crystal in the sacred grove.

The graphical issues are interesting:

The depth buffer glitch from the Linux version is also present here (surfaces being rendered in the wrong order)
Skeletal animations of entities don't work at all (e.g. walking animations)
~~some textures in the 3D world are garbled, notably that of the main character, chests, savepoints, fire and some other entities~~ Nevermind you just fixed that
Completely black textures or issues with red and blue being swapped are not present in the windows version, so e. g. 3D fights look correct (the background anyways, the characters are all transparent and garbled, also the sound popping is once again present here)

and also the pre-final boss stage is properly textured
In the Diablo part, performance issues are still there when fighting many enemies, and there's more audio popping during the boss fight. The ground and rock textures are still stretched (1st screenshot), and sometimes in the beginning the whole terrain is all over the place (2nd screenshot) so you can't see where you're going:
The bug from my previous comment where some ground textures in the 2D world suddenly became black came back in other places, like in the sacred grove towards the end, and during the end credits
Some objects are not rendered at all, like the stage of the final boss fight (just like in the Linux version), or wizards in the mines of Noria (you can only see their shadows)

Note: The final boss' eyes are supposed to be red like in this screenshot. In the screenshot of the Linux version in a previous comment they were purple, which was likely another issue with red/blue, but it's now also fixed and it's red in both versions of the game.

Here's a new archive of 18 savegames of various stages of the game: sharedObjects.tar.gz

That means the "virtual filesystem" is working correctly and is not the reason for the broken 3d models.

I'm not sure it's the 3D models that are themselves broken or loaded incorrectly. I think it's the 3D depth buffer / Z-order that is broken.
The overall shape of the 3D objects looks pretty much correct after all, but, for example, when the main character is looking at the camera, instead of his face you see basically the inside of the back of his head as it is drawn on top of the face even though the face should be drawn on top (if that makes sense), and in the "Mines of Noria" the lava is often drawn on top of the floor that is raised above the lava.
I've seen this phenomenon before in some other old game (not in Lightspark), which is why I (believe that I) immediately recognized it.

Original game:

I don't know a whole lot about 3D graphics so sorry for rambling on about it without really knowing what I'm talking about but I just figured I might as well share this idea in case you hadn't thought of it ;)

I'm curious about one thing though: Are there any other 3D flash games that work in Lightspark yet, and do they have similar problems? I don't know that many flash games overall and "3d adobe flash game" is not a very expedient search term, but it would be interesting to see if Lightspark's depth buffer (assuming I'm right about this) is universally broken / glitchy.

dbluelle · 2022-01-18T19:04:45Z

I think you are right about the z-buffer stuff. I'm currently using apitrace to get a deeper understanding of what's going on in the OpenGL part and the shaders.
I've not found many flash files that use the 3d stuff.
Evoland uses the haxe engine (see https://haxe.org/ ), so maybe there are other games that use this engine and are available as swf or AIR files.
Also searching for "Stage3D" flash games may get some results...

eiglow · 2022-01-19T00:12:20Z

I think one game which uses Stage3D is Running Fred, although at the moment it doesn't work.

dbluelle · 2022-01-23T15:03:50Z

Yeah, Running Fred seems to use the Unity engine, so maybe there are more flash games based on the Unity engine.
I've fixed Running Fred so that it doesn't crash anymore, but it still has graphical glitches and runs very, very, very... slow.

dbluelle · 2022-04-14T18:01:43Z

I think I've fixed the z-buffer issues with the latest commit :)
I haven't tested all your savegames, but at least on my test savegame everything is rendered correctly!

Firlaev-Hans · 2022-04-14T18:41:05Z

Indeed, and it also fixed the stretched ground textures in both Evoland 1 and Evoland 2!
There are some remaining graphical glitches, e. g. in the Linux version there are some black textures (e. g. during the final boss fight), wizards in the Noria mines are invisible in the Windows version, and probably a bunch more (e. g. frequent screen flashes). But at least it's mostly rendered correctly, I'd argue the Evoland 1 is now fully enjoyable in Lightspark... except:
There seems to have been a regression causing a crash during the final boss fight as well as during turn-based battles on the 3D world map (both in the Windows and the Linux version) so the game is no longer completable right now. I attached a gdb backtrace of the crash during a 3D battle in the Linux version:
linux3dfightcrash_backtrace.txt

dbluelle · 2022-04-17T18:17:40Z

I've fixed the crashes (at least on my savegame...) and the black textures should now be gone, too.

Firlaev-Hans · 2022-04-18T14:30:38Z

Great, those issues are indeed fixed now! However, while I have yet to do another playthrough I have done some more testing with my existing savegames and besides some minor already known issues that are remaining, there seem to have been more regressions.
(Testing done with Windows version, archive of savegames is here):

When you sleep at the Inn in Papunika Village (papunikaInnsave), the screen flickers indefinitely with the exception of the lower left corner. This reminds me a lot of the issue in Evoland 2 where opening the inventory or a name text input field will cause similar flickering.
At the beginning of the 3D part (post3dtransition) when you unlock pixelated textures, everything goes black except for the player, enemies and bushes will go black. Same thing goes for the overworld right after that part once you unlock the 3D overworld, for switching timelines in the sacred grove, and for the end credits.
Sometimes the " unlocked!" messages are bugged, making the text fields display the previous message

And then there are some remaining previously reported issues, notably these:

Painful audio popping during 3D turn based battles on the overworld, as well as during busy battles and the boss fight in the Diablo section
Slightly broken / aliased font rendering in windows version
In the Windows version in the mines of Noria, wizards are invisible (only their shadows can be seen), and so are hearts dropped by enemies or destroyed pots (if you load the provided Noria savegame and go to the far right and break the pot, you'll see it)
Various smaller graphical glitches which are minor enough that I don't feel like listing them all as they're barely worth looking into

Anyways, if you could figure out at least the black world regression, Papunika Inn flicker glitch, sound popping and perhaps the invisible wizards, I'd consider this game good enough that the issue can be closed. As I said, there are various tiny glitches left but fixing them all could take ages and probably isn't worth it.

dbluelle · 2022-07-17T16:09:58Z

I've fixed some of the issues:

the black textures don't appear anymore
the text rendering is now smoother and the "unlocked" messages shouldn't display the previous message anymore.
several audio issues in other games were fixed, maybe these fix the audio popping here, too (not tested).

The Papunika Inn flicker glitch seems to be related to playing in fullscreen. When switching to windowed (ctrl+f) everything is rendered as it should be.
Unfortunately the wizards and hearts int the mines of Noria are visible in the linux version (The actionscript code of the windows version is heavily obfuscated, so that's very hard to debug).

Firlaev-Hans · 2022-07-17T16:45:12Z

The audio popping is still there. The other two glitches are gone, including the "black world regression".
However, when in fullscreen, the game suddenly shrinks into the bottom left corner to a size equvalent to what the windowed size would be, when you unlock the 3D world, 3D textures or generally anything that changes the current scene significantly.
It's not quite like the Papunika flicker glitch, because here, the game actually properly resizes to the smaller size, rather than only rendering a small part of the image, and toggling fullscreen mode fixes it.

I can confirm that the Papunika flicker glitch doesn't happen when you exit full screen mode beforehand and use the Inn with the default window size. But it triggers if you resize the window (either before or after sleeping) as well, not just in fullscreen mode.
(As a side note, the inventory flickering in Evoland 2 is unrelated to the window size, I just tested it, so it's different from this)

Additionally, with the Mesa RadeonSI OpenGL driver, now the whole image "jitters" both in the main menu and in-game, which then goes away after a while but may come back briefly when e. g. using the sword. This wasn't the case two or three days ago when I did some testing. Using Zink (Mesa's OpenGL on Vulkan driver) or the proprietary AMD GL drivers, this issue is not present.

dbluelle · 2022-07-17T17:05:00Z

How can I to reproduce the audio popping error?

Firlaev-Hans · 2022-07-17T17:08:03Z

How can I to reproduce the audio popping error?

Either in the boss fight of the diablo part, or in 3D turn-based battles.
The fastest way would be loading one of the Aogai savegames, leaving the city and walking around the overworld map to trigger a turn-based battle.

dbluelle · 2022-07-20T16:48:21Z

I've fixed the Papunika flicker glitch!
I couldn't reproduce the audio issue, to me the turn based battle in Aogai save game sounds the same in lightspark as well as when running the game via wine.
Does the issue also occur when playing the linux version of the game?
Can you check if the "popping" sounds originate from the music or from the sound effects during the battle (by setting music/sound to off in the options) ?

Firlaev-Hans · 2022-07-20T18:37:21Z

The sound popping appears to be music related, as it doesn't happen with music at 0 (but sounds enabled), but it does with sound at 0 (and music enabled). Both in the Linux and Windows version.
Btw while testing I happened to go back to the main menu in-game with Esc, and I got this:

Firlaev-Hans · 2022-07-21T13:42:47Z

I have now confirmed that Evoland (Windows version) is once again 100% playable in Lightspark! I did another playthrough and this time I backed up savegames of every single point in the game and actually ordered them chronologically for once: evoSave.tar.gz

Besides the audio popping and the invisible wizards I also noticed memory leaks when loading new scenery just like in Evoland 2. Very noticeable when switching back and forth between 2D and 3D with the blue crystals in the sacred grove, or when navigating Aogai. Also there was a huge memory leak in the diablo part but I'm not sure if it is the same or not.

Besides that, there are only small graphical glitches, e. g. some textures being filtered when they shouldn't be, black outlines around textures with alpha, and some black lines between the individual "tiles" in the 3D world. All of those are very noticable in the 12_3DpixelTextures save game. I do not consider fixing these particularly important though. The memory leaks are the biggest issue.

I haven't done much more testing in the Linux version, though I noticed that all music is still delayed by ~1sec in that version. But I think people are much more likely to play the Windows version anyways considering the Linux version is hidden on Steam and not on GOG at all.

dbluelle · 2022-08-10T17:04:02Z

The wizards and the hearts are now rendered correctly.
I could reproduce the audio popping but have not yet found out why it occurs...

Firlaev-Hans · 2022-08-14T09:41:59Z

I could reproduce the audio popping but have not yet found out why it occurs...

My guess would be that there's something weird with the specific music files in question: battle_hd.mp3 for the 3D battles, and hs3.mp3 for busy Diablo battles and the Diablo boss fight, since the popping only always occurs when these specific tracks play.

dbluelle · 2023-01-14T16:39:00Z

I think I've fixed the sound issue, at least on my machine the popping has stopped.

This Diablo-esque part is almost unrecognizable:

The first encounter with the final boss suffers from black or missing objects:

During real the final boss fight it's even worse, and does impact gameplay
