Fix: Game not starting using pre alpha 2 on Ubuntu 10.04

[Snap]

Hello,

I wanted to test the game so I grabed it from playdeb.net. I can run the game, choose "Single player" and click on "Start the game" but the screen is blocked when the progress bar is full.

I started the game from a terminal and I got this:

gui/loading/loading.js(38): ReferenceError: curr_music is not defined

ERROR: JavaScript Error (gui/loading/loading.js, line 38): ReferenceError: curr_music is not defined

GAME STARTED, ALL INIT COMPLETE

To fix it, edit as root the file /usr/lib/games/0ad/data/mods/public/gui/loading/loading.js

sudo gedit /usr/lib/games/0ad/data/mods/public/gui/loading/loading.js

And replace at line 38

if (curr_music)

with

if (typeof(curr_music) != "undefined")

.

And then it works !

Hope this helps

Is this the 0.0.0+r07539~pre-alpha-1~getdeb1 package from PlayDeb? I don't understand why you get this problem when it appears to work fine for me and (as far as I'm aware) for most other people . Implicit global variables are yucky but it shouldn't fail randomly - functions_page_pregame.js sets curr_music which I think should make it available to other GUI scripts. Do you have other problems with music/sounds not playing, which might make this work differently? (I could apply this fix to the code in SVN but I'd prefer to understand the problem first.)

Yes, this is exactly this package. I don't understand. I have no sound until game is started.

Here is the complete log taken from terminal:

I'm not a JavaScript expert, but you seem to be right. As long as you do not write "var" before curr_music, it is global and should be accessible from everywhere. Could it be possible for the file functions_page_pregame.js to be loaded/parsed *after* loading.js ? What JavaScript engine do you use ?

Good luck, if you find the solution I'm curious to know it !

What JavaScript engine do you use ?

SpiderMonkey (as used in Firefox etc). I committed a fix in r7550 a while ago since I encountered a similar problem when making the game launch directly into the loading screen skipping the menu - I don't think that's the same problem (so I don't know what the original problem was) but it's the same solution so hopefully it'll work okay.
