juj / emscripten-scummvm Goto Github PK

I've been trying to follow the tutorial, and I've been running into a lot of problems.

I think I've done everything correctly in steps 1-7. I resolved some issues by using the full path name instead of ~.

Trying to run emmake make results in the following output:

    C++      backends/platform/sdl/sdl.o
In file included from ./backends/platform/sdl/sdl.h:26:0,
                 from backends/platform/sdl/sdl.cpp:31:
./backends/platform/sdl/sdl-sys.h:55:17: fatal error: SDL.h: No such file or directory
 #include <SDL.h>
                 ^
compilation terminated.
make: *** [backends/platform/sdl/sdl.o] Error 1

I'm not sure how to debug this. I'm on a fresh install of Ubuntu 14.04, and might be missing packages. I think I'm supposed to load the SDL.h that is included in emscripten, but don't know how to point it there. I've edited the copy of sdl-config in the emscripten folder and ran configure with the sdl argument pointing t the emscripten folder as well.

It is not possible to play your own games with the current web version. This is a copyright/hosting issue, since we cannot put copyrighted games up on the web servers. Investigate other solutions for this (perhaps user locally adds the game files to the web app, or similar).

Not a big priority at the moment, we are more interested in polishing the experience across browsers and increasing performance to make it smooth for all.

In Chrome or Firefox, when one minimizes the browser window, the audio playback immediately becomes choppy.

Perhaps should just pause audio when game is not active. See here for help http://stackoverflow.com/questions/1060008/is-there-a-way-to-detect-if-a-browser-window-is-not-currently-active .

Something about how this is implemented makes it impossible to allow audio on Firefox if "Apply these restrictions to whitelisted sites too" is checked in NoScript's Embeddings tab. (It allows me to keep YouTube whitelisted while reliably preventing autoplay)

Specifically, it keeps forcing NoScript to regenerate its menu so quickly that I can't keep the submenu open for more than a split second.

(While I can't read anything in the menu, would it be correct to guess that you're using an <audio> element which receives new data URIs almost constantly? NoScript does regenerate its menu whenever the list of blocked elements or the URIs they reference change.)

If so, my suggestion would be to add a test which detects that the audio element has been blocked and pauses during the interval after the element has been added but before the runtime starts to offer the user the option to select Allow *@domain from the NoScript menu.

Currently emscripten SDL api only implements audio for the Firefox browser, which is why audio doesn't work in other browsers.

After emscripten SDL audio adds support for other browsers, rebuild emscripten-scummvm to add audio support in the games to other browsers as well.

IE 10 supports neither Mozilla Audio Data API or Web Audio API, and therefore audio does not play back at all when run in IE10.

Possible fixes to this are probably quite exotic in nature. Very low priority at the moment.

It is probably due to my little knowledge of linux but I can't set the Variables in step 4 on Windows 10.
Are they environment variables, need to be entered into the .emscripten file or entered from the command prompt?
Sometimes I'd get a BINARYEN_ROOT is not defined or my PATH=$PATH:~/emscripten is wrong.
Thanks

Tried this twice in Chrome on the Mac and once Guybrush steps on the plank he keeps stepping on it in an infinite loop.

(This is the best bug report I've ever had to write by the way, thanks!)

Hey,

when I try to build my own emscripten-scummvm, it fails at "emmake make" with this error message:

What exactly is wrong and how can I fix it?

Once emscripten upstream gets all the necessary code so that it is possible to build scummvm with stock emscripten, write a build instruction page for anyone interested in contributing or hacking with emscripten-scummvm.

Use ctx.imageSmoothingEnabled = false to show the pixels in their full glory :)

http://jsfiddle.net/VAXrL/190/

When run inside the Opera browser, the whole browser crashes the moment any of the games starts.

Doesn't seem to matter when you do it, but my cpu spins up to 100%.

On a chrome 27.0.1453.110 m, windows 7 system running Maniac Mansion gave

Uncaught Assertion failed: _mixerReady, at: audio/mixer.cpp,238,virtual void Audio::MixerImpl::playStream(Audio::Mixer::SoundType, Audio::SoundHandle *, Audio::AudioStream *, int, byte, int8, DisposeAfterUse::Flag, bool, bool) at Error

Other games seem to run fine.

Now consistently reproduced, the latest Firefox stable hangs on Windows 7 systems at least momentarily in the start of the DOTT cutscene where purple tentacle drinks the water. Audio also stops.

Waiting for 5-10 seconds resolves the block and the playback and audio continues.

Tested the latest Firefox nightly on the same computer, and it works without pauses, so this might be fixed in Firefox.

The advanced image scalers were disabled since Emscripten SDL support does not have proper 16-bit SDL surface support (but treats all surfaces as 32-bit internally). Add back support to the more advanced scalers for better graphics effects.

This is related to issue #12.

The full version of Beneath a Steel Sky is freely available for download at http://scummvm.org/downloads/ . Add support for that game.

It looks like voice playback lags behind the animated characters when playing Sam&Max.

The colors of the mouse cursor are rendered wrong in all games.

Comi uses the scumm7-8 engine, which is slightly different to compile than the scumm0-6 engine set.

I have this partially working, video doesn't play back, and audio doesn't work, and some other stuff seems to be broken.

Add support for this.

Parts of the functionality have been done in a straighest-route-to-victory manner, adding workarounds first to get a clear picture of the amount of hurdles that lie ahead.

Now that the system is actually functional and the set of obstacles known, go back and report all issues and fixes to upstream emscripten, and see proper fixes for the workarounds, if possible.

In mobile Nexus 7 tablet device with Android 4.2.2 and Firefox 21.0:

Starting up, baseline Firefox takes up 100MB of memory.
While playing Monkey 1, Firefox consumes 200MB - 261 MB of memory.
While playing Sam & Max 1, Firefox consumes 271MB - 290 MB of memory.

The same device with the Opera 14.0.1074.56201 browser:
baseline: 108 MB,
Monkey 1: 221 MB (in two different processes)

The same device with the Chrome 27.0.1453.90 browser:
baseline: 72MB
Monkey 1: 189 MB

In native Win32 exe:
baseline: 8 MB,
while playing Monkey 1: 20MB,
Sam & Max 1: 21MB.

In both games, Firefox gives about 8-10x memory consumption compared to native.

Anyway, I'm doing my best to try and compile this on a Debian sid chroot, and the main hold up appears to be when I try to compile with emscripten, it cannot find any version of sdl-config, where as attempting to configure as normal gives me no issues whatso ever. Are the build intructions out of date in regards to emscripten changing around where some things are? Or would I have better luck with Retroarch in regards to compiling Scumm around emscripten?

The Safari browser renders the whole game screen completely wrong.

In fullscreen mode, the mouse cursor is stuck to the top-left corner of the screen.

In IE, the progress bar just doesn't hide, even if display:none; or hidden=1 is set to the element. Fix with something else.

The mouse cursor is stuck at top-left on IE.

This is probably due to the same reason as issue #3.

Trying to compile emscripten-scummvm under Mac OS X 10.9 yields the following errors.

Am I assuming correctly that it requires older SDL headers I might be lacking or is this something entirely different?

I've also tried building this with an older emscripten fork (the one hosted in one of your repositories), hoping this was simply an architectural change in the newer releases of emscripten.

Unfortunately, to no avail.

Hi there,

I had to hackup the configure script to compiled on Ubuntu 18.04 with Emscripten 1.38.27. It was giving an error about GCC version > 2.7 required as I recall. All said and done I finally got it to generate the scummvm.html .data .js and .wasm files. It seems to be working but all I see is this:

scummvm: Stray argument ''
Usage: scummvm [OPTIONS]... [GAME]

Try 'scummvm --help' for more options.

It clearly seems that scummvm is running without any arguments...problem is where are these defined?

i used the pre-load path in the export and I DO see the files being packaged...Am I missing a scummvm.ini or something else to tell it it's "Zak" or "Maniac"? I put a scummvm.ini in the game folder but that doesn't seem to make a difference.

I've compiled dosbox-x emscripten fork and that required me to have an entry in dosbox.conf to mount the packaged game folder and execute a BAT (or EXE) to start the game.

Any hints to complete this (I really want to get Zak FM-Towns working hehe) is greatly appreciated please and thank you for the fork! :)

EDIT: I removed some checks from the configure script I mentioned above - testing again on new source folder - this is the error:
