Ahhh...

Rings was saying on IRC that without the media, it wouldn't be possible to test the source code.

So, I have shared in Dropbox the full game: https://dl.dropboxusercontent.com/u/306 ... cecode.zip

Please notice that the graphics are from Microsoft Word Clipart and also from the ZX Spectrum game (this is a remake). They are just there until I replace them with the final release graphics still to be developed.

In paths, please notice that in Linux you have to change "\" with "/".

Thanks!

Kind regards,

In paths, please notice that in Linux you have to change "\" with "/".

You can just use "/" and it will work on both linux and windows.

I tried to guess a word right and one wrong, in both cases it didn't crash (pb511 x86 / win7 x64).

Unless you are saying it crashes only on linux, because it's not clear.

[marcoagpinto]

Unless you are saying it crashes only on linux, because it's not clear.

Yes, it crashes only on Linux.

On Windows 8 it works without any problems.

[Shardik]

I tested your source code on Kubuntu 12.04 LTS x86. After changing all "\" to "/" I discovered the problem with your code: You should never use LoadMovie() without checking whether the file was successfully loaded. Otherwise you might produce a crash! On Linux LoadMovie() always returns an error when trying to load an mp3 file because mp3 files are only supported on Windows:
http://www.purebasic.fr/english/viewtop ... 37&t=53683

No, the movie lib was never intended to play mp3. It does work on Windows because of the DirectShow plugin management but it's not the rule. The help should be changed.

[luis]

Well, we can say no return value is actually ever tested in that code, not the init*(), not the loadimage(), not the loadmovie(). And this is a tiny program. Ignoring return values usually is not a good idea.

[marcoagpinto]

Buaaaaaaaaaaaa

So, I can't use MP3s on Linux?

but, if I place audio in WAV the files will become huge.

Is there any other way of solving the issue?

Thanks!

Kind regards from Marco A.G.Pinto

[Fred]

There is an OGG lib for that, see: http://www.purebasic.com/documentation/ ... coder.html. Use it with PlaySound() and the streaming flag and should do the work. BTW, you don't have the right to play mp3 unless you paid a licence for the decoder.

Fred, I have changed all audio to .ogg format and it still crashes on Ubuntu 12.10...

What am I doing wrong?

Thanks!

[luis]

Updating your code in the first post or better yet on dropbox (new media included) with the changes you made could help.

Did you add the checks for the values returned by the commands or are you still ignoring them ?

With "changed all audio to .ogg format" do you mean you also stopped to use LoadMovie and switched to LoadSound, PlaySound ? Because it's not clear.

At least with these answers maybe someone else on linux can try to help you.

[marcoagpinto]

ahhhh...

here is the new source code: https://dl.dropboxusercontent.com/u/306 ... cecode.zip

I placed the load commands (fonts, audio and images) inside a procedure to make the code more modular.

Thanks for your help!

Kind regards,

I tried to run it under a VM with Linux mint x64 and PB 5.11 x64 but for some reason all the keyboard commands seems to have problems, I type and the chars go to the ide instead of the main program window, etc.
All seems to go upside down as soon graphical/keyboard commands are involved.
I'm sorry but you'll have to wait for someone with a real linux installation to check it, I cannot help.

[LuCiFeR[SD]]

I suspect it maybe related to this

[luis]

I suspect it maybe related to this

Could be, thank you.

[marcoagpinto]

Hello my dear ones,

I told Rings on IRC that my game still crashes even though I placed the hints to check if screens and files are opened.

This happens on my VM with Ubuntu 12.10 x86 with PureBasic 5.11 x86.

The source code is here: https://dl.dropboxusercontent.com/u/306 ... gman_5.zip

Could you take a look please?

Thanks!

Kind regards,
